What Is a 51% Attack? Binance Academy - Bitcoin Exchange

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low
Bearish:
A tendency of prices to fall; a pessimistic expectation that the value of a coin is going to drop.
Bear trap:
A manipulation of a stock or commodity by investors.

Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:
An unchangeable digital record of all transactions ever made in a particular cryptocurrency and shared across thousands of computers worldwide. It has no central authority governing it. Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.

ABSTRACT

Aryacoin is a new cryptocurrency, which allows for decentralized, peer to peer transactions of electronic cash. It is like Bitcoin and Litecoin, but the trading of the coin occurs on sales platforms that have no restriction to use. Further, it was created with the goal of addressing the double spend issues of Bitcoin and does so using a timestamp server to verify transactions. It works by taking the hash of a block of items to be timestamped and widely publishing the hash. The timestamp proves that the data must have existed at the time in order to get the hash. Each timestamp then includes the previous timestamp in its hash, forming a chain.
The Aryacoin team is continuously developing new use cases for the coin, including exchanges where users can exchange the coins without any fees or restrictions, and offline options where the coins can be bought and sold for cash. The coins can also be used on the company’s other platform, mrdigicoin.io. Along with the coin, there is a digital wallet that can be created and controlled by the user entirely, with no control being retained by the Aryacoin team.

1.INTRODUCTION

The concept of Blockchain first came to fame in October 2008, as part of a proposal for Bitcoin, with the aim to create P2P money without banks. Bitcoin introduced a novel solution to the age-old human problem of trust. The underlying blockchain technology allows us to trust the outputs of the system without trusting any actor within it. People and institutions who do not know or trust each other, reside in different countries, are subject to different jurisdictions, and who have no legally binding agreements with each other, can now interact over the Internet without the need for trusted third parties like banks, Internet platforms, or other types of clearing institutions.
When bitcoin was launched it was revolutionary allowing people to transfer money to anytime and anywhere with very low transaction fees . It was decentralized and their is no third party involved in the transaction , only the sender and receiver were involved.
This paper provide a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes. Bitcoin was made so that it would not be controlled or regulated but now exchanges and governments are regulating bitcoin and other cryptocurrencies at every step. Aryacoin was developed to overcome these restrictions on a free currency.
Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.

1.1 OVERVIEW ABOUT ARYACOIN

Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.
Aryacoin is a blockchain based project that allows users to access their wallet on the web and mobile browsers, using their login details.
Aryacoin can be mined; it also can be exchanged by other digital currencies in several world-famous exchanges such as Hitbtc, CoinEx, P2pb2b, WhiteBit, Changelly and is also listed in reputable wallets such as Coinomi and Guarda.
Aryacoin is a coin, which can be used by anyone looking to use cryptocurrency which allows them to keep their privacy even when buying/selling the coin along with while using the coin during transactions. Proof of work and cryptographic hashes allows transactions to verified.
Stable Fee Per AYA is a unique feature of Aryacoin, so by increasing the amount or volume of the transaction, there is no change in the fee within the network, which means that the fee for sending an amount less than 1 AYA is equal to several hundred million AYA. Another unique feature of Aryacoin is the undetectability of transactions in Explorer, such as the DASH and Monero, of course, this operation is unique to Aryacoin.
Using Aryacoin digital currency, like other currencies, international transactions can be done very quickly and there are no limitations in this area as the creators claim.
Aryacoin aims to allow users to access the Aryacoin wallet via the web and mobile browsers using their login details.
Aryacoin is a peer-to-peer electronic cash system that enables users to send and receive payments directly from one party to another, and allow them to transfer funds across borders with no restriction or third party involvement. The blockchain-based system embraces the digital signature, which prevents double spending and low transfer fees, which enables users to transfer huge amounts with very low fees. The proof-of-work consensus mechanism allows each transaction to be verified and confirmed, while anonymity enables users to use the coin anywhere at any time.
According to the website of the operation, each wallet is divided into 2 or more AYA wallet addresses for each transaction, and depending on the volume of the transaction block, the origin, and destination of transactions in the network can not be traced and displayed to the public.
In fact, each wallet in Aryacoin consists of a total of several wallets. The number of these wallets increases per transaction to increase both security and privacy. Aryacoin also uses the dPoW protocol. In the dPoW protocol, a second layer is added to the network to verify transactions, which makes “51% attack” impossible even with more than half of the network hash, and blocks whose Blockchain uses this second layer of security never run the risk of 51% attacks.
AYA has been listed on a number of crypto exchanges, unlike other main cryptocurrencies, it cannot be directly purchased with fiats money. However, You can still easily buy this coin by
first buying Bitcoin from any large exchanges and then transfer to the exchange that offers to trade this coin.

1.1.1 ARYACOIN HISTORY

Aryacoin (AYA) is a new cryptocurrency, which has been created by a group of Iranian developers, is an altcoin which allows for decentralised, peer to peer transactions of electronic cash without any fees whatsoever. Along with the coin, there is a digital wallet that can be created and managed by the user entirely, with no control being retained by the Aryacoin team.
Aryacoin’s founder, Kiumars Parsa, has been a fan of alternative currencies and particularly Bitcoin.
We see people from all around the world using Blockchain technology and the great benefits that came with it and it then that I decided to solve this puzzle for find a way of bringing the last missing piece to the jigsaw. The idea for Aryacoin was born.” Parsa said.
Parsa and his team of Iranian ex-pats not only persevered but expedited the project and just a year later, in the summer of 2019, the first version of Aryacoin was released. In 2020, Aryacoin is the first and only Iranian coin listed on CMC.
Parsa goes on to state that it is now the strength of the community that has invested in the coin that will ultimately drive its success, alongside its robust technology and appealing 0% network fees.
We have thousands of voices behind Aryacoin. People for the people make this coin. It is a massive shout out for democracy. This had made us base the whole team strategy on the benefits for both our users and our traders.
One key example is that the network fee on AYA Blockchain is 0%. Yes, absolutely nothing, which which differentiates us from other networks. What also differentiates us from other coins is that we have AYAPAY which is the first cryptocurrency Gateway in the world which does not save funds on third party storage with all funds being forwarded directly to any wallet address that the Gateway owner requests”.
So for the first time ever, and unlike other gateways, incoming funds will be saved on the users account with submitted withdrawal requests then made on the Gateway host website. In AYAPAY which has also been developed by the Aryacoin team, all funds without extra fees or extra costs will directly forwarded to users wallets. We have named this technology as CloudWithdrawal.
We are continuously challenging ourselves as it is a crowded marketplace. We are striving to have a safer Blockchain against 51% attacks, faster confirmations speeds of transactions, cheaper network fee, growing the market by cooperation with Top tier Exchangers.

1.1.2 ARYACOIN’S MAIN GOAL

Aryacoin’s main goal is to educate people and give them the freedom to use cryptocurrency in any way they want. Aryacoin empowers the users to transfer, pay, trade cryptocurrency from any country around the globe.

1.1.3 PROBLEM ARYACOIN SEEKS TO SOLVE

Aryacoin aims to provide a long-term solution to the problem of double spending, which is still common in the crypto market. The developers of the system have created a peer-to-peer distributed timestamp server that generates computational proof of the transactions as they occur.
Besides, the system remains secure provided honest nodes control more CPU power than any cooperating group of attacker nodes. While Bitcoin was designed not to be regulated or controlled, many exchanges and governments have put regulatory measures on the pioneer cryptocurrency at every step. Aryacoin aims to overcome these restrictions as a free digital currency.

1.1.4 BENEFITS OF USING ARYACOIN

Aryacoin solution offers the following benefits:

1.1.5 ARYACOIN FEATURES

1. Anonymity
The coin provides decent level of anonymity for all its users. The users can send their transactions to any of the public nodes to be broadcasted , the transaction sent to the nodes should be signed by the private key of the sender address . This allows the users to use the coin anywhere any time , sending transactions directly to the node allows users from any place and country .
2. Real Life Usage
aryacoin’s team is continuously developing new and innovative ways to use the coins , they are currently developing exchanges where the users can exchange the coins without any fees and any restrictions . They also are currently developing other innovative technologies, which would allow users to spend our coins everywhere and anywhere.
3. Offline Exchanges
They are also working with different offline vendors which would enable them to buy and sell the coins directly to our users on a fixed/variable price this would allow easy buy/sell directly using cash . This would allow the coins to be accessible to users without any restrictions which most of the online exchanges have, also increase the value and number of users along with new ways to spend the coin. This would increase anonymity level of the
coin. In addition, introduce new users into the cryptomarket and technology. Creating a revolution, which educates people about crypto and introduce them to the crypto world, which introduces a completely new group of people into crypto and a move towards a Decentralized future!
4. Transactions
When it comes to transactions, Aryacoin embraces a chain of digital signatures, where each owner simply transfers the coin to the next person by digitally signing a hash of the previous transaction and the public key of the next owner. The recipient can then verify the signatures to confirm the chain of ownership. Importantly, Aryacoin comes with a trusted central authority that checks every transaction for double spending.
5. Business Partner with Simplex
Aryacoin is the first and only Iranian digital currency that managed to obtain a trading license in other countries.
In collaboration with the foundation and financial giant Simplex, a major cryptocurrency company that has large companies such as Binance, P2P, Changelly, etc. Aryacoin has been licensed to enter the world’s major exchanges, as well as the possibility of purchasing AYA through Credit Cards, which will begin in the second half of 2020.
Also, the possibility of purchasing Aryacoin through Visa and MasterCard credit cards will be activated simultaneously inside the Aryacoin site. plus, in less than a year, AYA will be placed next to big names such as CoinCapMarket, Coinomi, P2P, Coinpayments and many other world-class brands today.

1.1.6 WHY CHOOSE ARYACOIN?

If you want to use a cryptocurrency that allows you to keep your privacy online even when buying and selling the coins, the Aryacoin team claims that AYA is the way to go. Aryacoin is putting in the work: with more ways to buy and sell, and fixing the issues that were present in the original Bitcoin, plus pushing the boundaries with innovative solutions in cryptocurrencies. You can get started using Aryacoin (AYA) payments simply by having a CoinPayments account!

1.1.7 ARYANA CENTRALIZED EXCHANGE

Aryana, the first Iranian exchange is a unique platform with the following features:
  • The first real international Persian exchange that obtains international licenses and is listed in CoinMarketCap.
  • The first Iranian exchange that has been cooperating with a legal and European exchange for 3 years.
  • The possibility of trading in Tomans (available currency in Iran) at the user’s desired price and getting rid of the transaction prices imposed by domestic sites inside Iran.
  • There is an internal fee payment plan by Iranian domestic banks for depositing and withdrawing Tomans for Aryacoin holders in Aryana Exchange.
  • The number that you see on the monitor and in your account will be equal to the number that is transferred to your bank account without a difference of one Rial.
  • The last but not least, noting the fact that there is a trading in Tomans possibility in Aryana exchange.
Aryana Exchange is using the most powerful, fastest, and most expensive server in the world, Google Cloud Platform (GCP), which is currently the highest quality server for an Iranian site, so that professional traders do not lag behind the market even for a second.
The feature of Smart Trading Robots is one of the most powerful features for digital currency traders. Digital cryptocurrency traders are well aware of how much they will benefit from smart trading robots. In the Aryana exchange, it is possible to connect exchange user accounts to intelligent trading bots and trade even when they are offline.
The injection of $ 1 million a day in liquidity by the WhiteBite exchange to maintain and support the price of Tether and eliminate the Tether fluctuations with Bitcoin instabilities used by profiteers to become a matter of course.

1.1.8 HOW DOES ARYACOIN WORK?

Aryacoin (AYA) tries to ensure a high level of security and privacy. The team has made sure to eliminate any trading restrictions for the network users: no verification is required to carry out transactions on AYA, making the project truly anonymous, decentralized, and giving it a real use in day-to-day life. The Delayed-Proof-of-Work (dPoW) algorithm makes the Aryacoin blockchain immune to any attempts of a 51% attack. AYA defines a coin as a chain of digital signatures — each owner transfers the coin to the next owner by digitally signing the hash of the previous transaction and the public key of the next owner, and the receiver verifies the signatures and the chain of ownership.

2. ARYACOIN TECHNOLOGY

2.1 PROOF-OF-WORK

They use a proof-of-work system similar to Adam Back’s Hashcash to implement a distributed timestamp server on a peer-to-peer basis, rather than newspaper or Usenet publications. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash.
For their timestamp network, they implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it.
The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If honest nodes control a majority of CPU power, the honest chain will grow the fastest and outpace any competing chains. To modify a past
block, an attacker would have to redo the proof-of-work of the block and all blocks after it, then catch up with, and surpass the work of the honest nodes.

2.2 NETWORK

The steps to run the network are as follows:
  • New transactions are broadcast to all nodes.
  • Each node collects new transactions into a block.
  • Each node works on finding a difficult proof-of-work for its block.
  • When a node finds a proof-of-work, it broadcasts the block to all nodes.
  • Nodes accept the block only if all transactions in it are valid and not already spent.
This is a very simple system that makes the network fast and scalable, while also providing a decent level of anonymity for all users. Users can send their transactions to any of the public nodes to be broadcast, and the private key of the sender’s address should sign any transaction sent to the nodes. This way, all transaction info remains strictly confidential. It also allows users to send transactions directly to the node from any place at any time and allows the transferring of huge amounts with very low fees.

2.3 AYAPAY PAYMENT SERVICES GATEWAY:

According to creators Aryacoin, the development team has succeeded in inventing a new blockchain technology for the first time in the world, which is undoubtedly a big step and great news for all digital currency enthusiasts around the world.
This new technology has been implemented on the Aryacoin AYAPAY platform and was unveiled on October 2. AYAPAY payment platform is the only payment gateway in the world that does not save money in users’ accounts and transfers incoming coins directly to any wallet address requested by the gateway owner without any additional transaction or fee.
In other similar systems or even systems such as PayPal, money is stored in the user account.

2.4 CONSENSUS ALGORITHM IN ARYACOIN

The devs introduced the Delayed-Proof-of-Work (dPoW) algorithm, which represents a hybrid consensus method that allows one blockchain to take advantage of the security provided by the hashing power of another blockchain. The AYA blockchain works on dPoW and can use such consensus methods as Proof-of-Work (PoW) or Proof-of-Stake (PoS) and join to any desired PoW blockchain. The main purpose of this is to allow the blockchain to continue operating without notary nodes on the basis of its original consensus method. In this situation, additional security will no longer be provided through the attached blockchain, but this is not a particularly significant problem. dPoW can improve the security level and reduce energy consumption for any blockchain.

2.5 DOUBLE-SPEND PROBLEM AND SOLUTION

One of the main problems in the blockchain world is that a receiver is unable to verify whether or not one of the senders did not double-spend. Aryacoin provides the solution, and has established a trusted central authority, or mint, that checks every transaction for double-spending. Only the mint can issue a new coin and all the coins issued directly from the mint are trusted and cannot be double-spent. However, such a system cannot therefore
be fully decentralized because it depends on the company running the mint, similar to a bank. Aryacoin implements a scheme where the receiver knows that the previous owners did not sign any earlier transactions. The mint is aware of all transactions including which of them arrived first. The developers used an interesting solution called the Timestamp Server, which works by taking a hash of a block of items to be ‘timestamped’ and publishing the hash. Each timestamp includes the previous timestamp in its hash, forming a chain. To modify a block, an attacker would have to redo the proof-of-work of all previous blocks, then catch up with, and surpass the work of the honest nodes. This is almost impossible, and makes the network processes more secure. The proof-of-work difficulty varies according to circumstances. Such an approach ensures reliability and high throughput.

Passive investing strategy

I have been holding crypto and following the ecosystem for a long time, and I believe crypto will revolutionise the financial system and still has much potential to increase in value.
However until now my holdings have been mostly handpicked. In traditional investments I am a subscriber to passive investing and usually invest in broad index funds, and I want to apply that investment philosophy to my crypto holdings.
With this in mind I looked at some available crypto indices and none of them seemed to fill my needs, but looking at them helped me define some of the criteria for my own index:
I will be reproducing the index manually, so having too many assets will make the extra hassle of trading and storing the small-weighted assets not worth it.
I don't see the point of including stablecoins in a cryptoasset index. If I wanted to invest in the asset the stablecoin tracks I'd be better off holding the followed asset itself.
All indices I found included assets such as Binance Coin and OKB. I see investing in such assets as investing in the managing entity and not in the crypto ecosystem itself, as those tokens will be much more correlated with the business success of the entity than with the success of the ecosystem.
The asset must be available for trading in a reasonable number of exchanges.
Free-float market cap weighting is the standard method of weighting whole-market indices. I have seen some indices that use square root of market cap weighting in order to not be so Bitcoin-heavy, but I am not convinced that that is a better representation of the market or that it would lead to better returns.
With these criteria in mind I evaluated the top coins by market capitalization. I decided to use CoinGecko as my main source, but I do cross check the values with CoinMarketCap and CoinCap.io to avoid some big flaw in CoinGecko's methodology.
Obviously the big guy is in.
I also have no issues with Ethereum.
Ripple is a bit too centrally-controlled for my taste and there's also the worry that the value of the XRP token itself may not be too correlated with the network's success, but I still consider it to be worthy for inclusion.
Tether is excluded due to being a stable coin and being centrally-controlled.
The only thing that worries me about Bitcoin Cash is that the community seems to be too worried about insisting that it is the true Bitcoin instead of developed, but I don't see any reason to exclude it given my criteria.
This is the first asset with which I don't have too much experience. Their website is a bit too heavy on buzzwords, but my research seems to show that it is a real network, there's no big problems with their whitepaper.
I personally have no idea how Bitcoin SV is so high in market capitalization, as I see it as just Craig Steven Wright's tool to strengthen his Satoshi claim, but the point of the index and the criteria is to remove my personal feelings from the decision, so it stays in.
Litecoin is one of the oldest assets around and I have no objection for it.
This is the first one where I am having a hard time deciding if it stays in or not. Its website is full of buzzwords. They have a whitepaper explaining how the network works, but I can't see it as much more than a centrally-managed token with a bunch of apps around it and no real value proposition. The company itself seems shady, having been through a name change, as it was previously called Monaco, the way their cards work smells heavily like a Ponzi scheme, they promise huge interest rates for staking random coins with them and the amount of people that show up speaking well of it in any post about it reeks of paid shills.
For some reason it is also not listed on CoinCap.io, although it is listed on CoinGecko and CoinMarketCap. It is also listed on fewer exchanges than other coins we've seen so far.
I couldn't find any concrete evidence of it being a scam, but I am excluding it for being a centrally-controlled token.
This is a Binance-controlled token, so it is out.
I also didn't know much about this coin, but my research didn't raise any red flags about it, so it's in.
This one is an ERC20 token, but it is managed by a smart contract and although it seems to be somewhat centrally-controlled by now it does have a governance model to make this control be diluted over time. It is also trying to solve a real problem, so it is in.
I was not too familiar with it, but after researching about it I really like the idea. I see no problem in including it.
Stellar feels to me a bit too much like Ripple 2.0, but I don't have any concrete problems with it.
This is an OKEX-controlled token, so it is out.
Another one of the old kids in town, I have no problems with it.
I have a "too buzzwordy" feeling about TRON, and I feel it is a bit too much connected to its founder, but no concrete problems as well.
This is a bitfinex-controlled token, so it is out.
USD Coin is excluded due to being a stable coin and being centrally-controlled.
This is an asset that I am not too sure I understand completely, and it is not listed from CoinCap.io and its market cap is not computed on CoinMarketCap.
From what I can gather a cToken is meant to be a token that identifies that you have deposited in Compound's loan market. The only place where it is really traded is in the Compound exchange itself, and it's value is tied to the interest accrued from the loans in the platform and to the underlying asset, which in this case is DAI, a stablecoin.
I find Compound Finance interesting and intend to read more about it, but I don't think cDAI is fit for my index, as it is not freely tradeable and tied to a stablecoin.
This is a Huobi-controlled token, so it is out.
This is one more buzzwordy smart contract platform with no concrete red flags to it.
A fork from the main Ethereum chain that rejects the rescue of stolen funds from a buggy smart contract. I am sympathetic to the idea of rejecting a centrally-proposed hardfork, and I see no red flags with this coin.
And with this we are up to my intended 15 assets. This is the composition of the index with current market capitalizations:
Asset Weight
bitcoin 72,29%
ethereum 12,71%
ripple 3,80%
bitcoin-cash 1,89%
cardano 1,56%
bitcoin-cash-sv 1,42%
litecoin 1,28%
eos 1,03%
chainlink 0,96%
tezos 0,73%
stellar 0,71%
monero 0,51%
tron 0,46%
vechain 0,36%
ethereum-classic 0,30%
This is the portfolio I intend to target from now on, with occasional rebalances of course. I would like to hear what you think about my criteria and my application of them, and where I could improve it.

How To End The Cryptocurrency Exchange "Wild West" Without Crippling Innovation


In case you haven't noticed the consultation paper, staff notice, and report on Quadriga, regulators are now clamping down on Canadian cryptocurrency exchanges. The OSC and other regulatory bodies are still interested in industry feedback. They have not put forward any official regulation yet. Below are some ideas/insights and a proposed framework.



Many of you have limited time to read the full proposal, so here are the highlights:

Offline Multi-Signature

Effective standards to prevent both internal and external theft. Exchange operators are trained and certified, and have a legal responsibility to users.

Regular Transparent Audits

Provides visibility to Canadians that their funds are fully backed on the exchange, while protecting privacy and sensitive platform information.

Insurance Requirements

Establishment of basic insurance standards/strategy, to expand over time. Removing risk to exchange users of any hot wallet theft.


Background and Justifications


Cold Storage Custody/Management
After reviewing close to 100 cases, all thefts tend to break down into more or less the same set of problems:
• Funds stored online or in a smart contract,
• Access controlled by one person or one system,
• 51% attacks (rare),
• Funds sent to the wrong address (also rare), or
• Some combination of the above.
For the first two cases, practical solutions exist and are widely implemented on exchanges already. Offline multi-signature solutions are already industry standard. No cases studied found an external theft or exit scam involving an offline multi-signature wallet implementation. Security can be further improved through minimum numbers of signatories, background checks, providing autonomy and legal protections to each signatory, establishing best practices, and a training/certification program.
The last two transaction risks occur more rarely, and have never resulted in a loss affecting the actual users of the exchange. In all cases to date where operators made the mistake, they've been fully covered by the exchange platforms.
• 51% attacks generally only occur on blockchains with less security. The most prominent cases have been Bitcoin Gold and Ethereum Classic. The simple solution is to enforce deposit limits and block delays such that a 51% attack is not cost-effective.
• The risk of transactions to incorrect addresses can be eliminated by a simple test transaction policy on large transactions. By sending a small amount of funds prior to any large withdrawals/transfers as a standard practice, the accuracy of the wallet address can be validated.
The proposal covers all loss cases and goes beyond, while avoiding significant additional costs, risks, and limitations which may be associated with other frameworks like SOC II.

On The Subject of Third Party Custodians
Many Canadian platforms are currently experimenting with third party custody. From the standpoint of the exchange operator, they can liberate themselves from some responsibility of custody, passing that off to someone else. For regulators, it puts crypto in similar categorization to oil, gold, and other commodities, with some common standards. Platform users would likely feel greater confidence if the custodian was a brand they recognized. If the custodian was knowledgeable and had a decent team that employed multi-sig, they could keep assets safe from internal theft. With the right protections in place, this could be a great solution for many exchanges, particularly those that lack the relevant experience or human resources for their own custody systems.
However, this system is vulnerable to anyone able to impersonate the exchange operators. You may have a situation where different employees who don't know each other that well are interacting between different companies (both the custodian and all their customers which presumably isn't just one exchange). A case study of what can go wrong in this type of environment might be Bitpay, where the CEO was tricked out of 5000 bitcoins over 3 separate payments by a series of emails sent legitimately from a breached computer of another company CEO. It's also still vulnerable to the platform being compromised, as in the really large $70M Bitfinex hack, where the third party Bitgo held one key in a multi-sig wallet. The hacker simply authorized the withdrawal using the same credentials as Bitfinex (requesting Bitgo to sign multiple withdrawal transactions). This succeeded even with the use of multi-sig and two heavily security-focused companies, due to the lack of human oversight (basically, hot wallet). Of course, you can learn from these cases and improve the security, but so can hackers improve their deception and at the end of the day, both of these would have been stopped by the much simpler solution of a qualified team who knew each other and employed multi-sig with properly protected keys. It's pretty hard to beat a human being who knows the business and the typical customer behaviour (or even knows their customers personally) at spotting fraud, and the proposed multi-sig means any hacker has to get through the scrutiny of 3 (or more) separate people, all of whom would have proper training including historical case studies.
There are strong arguments both for and against using use of third party custodians. The proposal sets mandatory minimum custody standards would apply regardless if the cold wallet signatories are exchange operators, independent custodians, or a mix of both.

On The Subject Of Insurance
ShakePay has taken the first steps into this new realm (congratulations). There is no question that crypto users could be better protected by the right insurance policies, and it certainly feels better to transact with insured platforms. The steps required to obtain insurance generally place attention in valuable security areas, and in this case included a review from CipherTrace. One of the key solutions in traditional finance comes from insurance from entities such as the CDIC.
However, historically, there wasn't found any actual insurance payout to any cryptocurrency exchange, and there are notable cases where insurance has not paid. With Bitpay, for example, the insurance agent refused because the issue happened to the third party CEO's computer instead of anything to do with Bitpay itself. With the Youbit exchange in South Korea, their insurance claim was denied, and the exchange ultimately ended up instead going bankrupt with all user's funds lost. To quote Matt Johnson in the original Lloyd's article: “You can create an insurance policy that protects no one – you know there are so many caveats to the policy that it’s not super protective.”
ShakePay's insurance was only reported to cover their cold storage, and “physical theft of the media where the private keys are held”. Physical theft has never, in the history of cryptocurrency exchange cases reviewed, been reported as the cause of loss. From the limited information of the article, ShakePay made it clear their funds are in the hands of a single US custodian, and at least part of their security strategy is to "decline[] to confirm the custodian’s name on the record". While this prevents scrutiny of the custodian, it's pretty silly to speculate that a reasonably competent hacking group couldn't determine who the custodian is. A far more common infiltration strategy historically would be social engineering, which has succeeded repeatedly. A hacker could trick their way into ShakePay's systems and request a fraudulent withdrawal, impersonate ShakePay and request the custodian to move funds, or socially engineer their way into the custodian to initiate the withdrawal of multiple accounts (a payout much larger than ShakePay) exploiting the standard procedures (for example, fraudulently initiating or override the wallet addresses of a real transfer). In each case, nothing was physically stolen and the loss is therefore not covered by insurance.
In order for any insurance to be effective, clear policies have to be established about what needs to be covered. Anything short of that gives Canadians false confidence that they are protected when they aren't in any meaningful way. At this time, the third party insurance market does not appear to provide adequate options or coverage, and effort is necessary to standardize custody standards, which is a likely first step in ultimately setting up an insurance framework.
A better solution compared to third party insurance providers might be for Canadian exchange operators to create their own collective insurance fund, or a specific federal organization similar to the CDIC. Such an organization would have a greater interest or obligation in paying out actual cases, and that would be it's purpose rather than maximizing it's own profit. This would be similar to the SAFU which Binance has launched, except it would cover multiple exchanges. There is little question whether the SAFU would pay out given a breach of Binance, and a similar argument could be made for a insurance fund managed by a collective of exchange operators or a government organization. While a third party insurance provider has the strong market incentive to provide the absolute minimum coverage and no market incentive to payout, an entity managed by exchange operators would have incentive to protect the reputation of exchange operators/the industry, and the government should have the interest of protecting Canadians.

On The Subject of Fractional Reserve
There is a long history of fractional reserve failures, from the first banks in ancient times, through the great depression (where hundreds of fractional reserve banks failed), right through to the 2008 banking collapse referenced in the first bitcoin block. The fractional reserve system allows banks to multiply the money supply far beyond the actual cash (or other assets) in existence, backed only by a system of debt obligations of others. Safely supporting a fractional reserve system is a topic of far greater complexity than can be addressed by a simple policy, and when it comes to cryptocurrency, there is presently no entity reasonably able to bail anyone out in the event of failure. Therefore, this framework is addressed around entities that aim to maintain 100% backing of funds.
There may be some firms that desire but have failed to maintain 100% backing. In this case, there are multiple solutions, including outside investment, merging with other exchanges, or enforcing a gradual restoration plan. All of these solutions are typically far better than shutting down the exchange, and there are multiple cases where they've been used successfully in the past.

Proof of Reserves/Transparency/Accountability
Canadians need to have visibility into the backing on an ongoing basis.
The best solution for crypto-assets is a Proof of Reserve. Such ideas go back all the way to 2013, before even Mt. Gox. However, no Canadian exchange has yet implemented such a system, and only a few international exchanges (CoinFloor in the UK being an example) have. Many firms like Kraken, BitBuy, and now ShakePay use the Proof of Reserve term to refer to lesser proofs which do not actually cryptographically prove the full backing of all user assets on the blockchain. In order for a Proof of Reserve to be effective, it must actually be a complete proof, and it needs to be understood by the public that is expected to use it. Many firms have expressed reservations about the level of transparency required in a complete Proof of Reserve (for example Kraken here). While a complete Proof of Reserves should be encouraged, and there are some solutions in the works (ie TxQuick), this is unlikely to be suitable universally for all exchange operators and users.
Given the limitations, and that firms also manage fiat assets, a more traditional audit process makes more sense. Some Canadian exchanges (CoinSquare, CoinBerry) have already subjected themselves to annual audits. However, these results are not presently shared publicly, and there is no guarantee over the process including all user assets or the integrity and independence of the auditor. The auditor has been typically not known, and in some cases, the identity of the auditor is protected by a NDA. Only in one case (BitBuy) was an actual report generated and publicly shared. There has been no attempt made to validate that user accounts provided during these audits have been complete or accurate. A fraudulent fractional exchange, or one which had suffered a breach they were unwilling to publicly accept (see CoinBene), could easily maintain a second set of books for auditors or simply exclude key accounts to pass an individual audit.
The proposed solution would see a reporting standard which includes at a minimum - percentage of backing for each asset relative to account balances and the nature of how those assets are stored, with ownership proven by the auditor. The auditor would also publicly provide a "hash list", which they independently generate from the accounts provided by the exchange. Every exchange user can then check their information against this public "hash list". A hash is a one-way form of encryption, which fully protects the private information, yet allows anyone who knows that information already to validate that it was included. Less experienced users can take advantage of public tools to calculate the hash from their information (provided by the exchange), and thus have certainty that the auditor received their full balance information. Easy instructions can be provided.
Auditors should be impartial, their identities and process public, and they should be rotated so that the same auditor is never used twice in a row. Balancing the cost of auditing against the needs for regular updates, a 6 month cycle likely makes the most sense.

Hot Wallet Management
The best solution for hot wallets is not to use them. CoinBerry reportedly uses multi-sig on all withdrawals, and Bitmex is an international example known for their structure devoid of hot wallets.
However, many platforms and customers desire fast withdrawal processes, and human validation has a cost of time and delay in this process.
A model of self-insurance or separate funds for hot wallets may be used in these cases. Under this model, a platform still has 100% of their client balance in cold storage and holds additional funds in hot wallets for quick withdrawal. Thus, the risk of those hot wallets is 100% on exchange operators and not affecting the exchange users. Since most platforms typically only have 1%-5% in hot wallets at any given time, it shouldn't be unreasonable to build/maintain these additional reserves over time using exchange fees or additional investment. Larger withdrawals would still be handled at regular intervals from the cold storage.
Hot wallet risks have historically posed a large risk and there is no established standard to guarantee secure hot wallets. When the government of South Korea dispatched security inspections to multiple exchanges, the results were still that 3 of them got hacked after the inspections. If standards develop such that an organization in the market is willing to insure the hot wallets, this could provide an acceptable alternative. Another option may be for multiple exchange operators to pool funds aside for a hot wallet insurance fund. Comprehensive coverage standards must be established and maintained for all hot wallet balances to make sure Canadians are adequately protected.

Current Draft Proposal

(1) Proper multi-signature cold wallet storage.
(a) Each private key is the personal and legal responsibility of one person - the “signatory”. Signatories have special rights and responsibilities to protect user assets. Signatories are trained and certified through a course covering (1) past hacking and fraud cases, (2) proper and secure key generation, and (3) proper safekeeping of private keys. All private keys must be generated and stored 100% offline by the signatory. If even one private keys is ever breached or suspected to be breached, the wallet must be regenerated and all funds relocated to a new wallet.
(b) All signatories must be separate background-checked individuals free of past criminal conviction. Canadians should have a right to know who holds their funds. All signing of transactions must take place with all signatories on Canadian soil or on the soil of a country with a solid legal system which agrees to uphold and support these rules (from an established white-list of countries which expands over time).
(c) 3-5 independent signatures are required for any withdrawal. There must be 1-3 spare signatories, and a maximum of 7 total signatories. The following are all valid combinations: 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7.
(d) A security audit should be conducted to validate the cold wallet is set up correctly and provide any additional pertinent information. The primary purpose is to ensure that all signatories are acting independently and using best practices for private key storage. A report summarizing all steps taken and who did the audit will be made public. Canadians must be able to validate the right measures are in place to protect their funds.
(e) There is a simple approval process if signatories wish to visit any country outside Canada, with a potential whitelist of exempt countries. At most 2 signatories can be outside of aligned jurisdiction at any given time. All exchanges would be required to keep a compliant cold wallet for Canadian funds and have a Canadian office if they wish to serve Canadian customers.
(2) Regular and transparent solvency audits.
(a) An audit must be conducted at founding, after 3 months of operation, and at least once every 6 months to compare customer balances against all stored cryptocurrency and fiat balances. The auditor must be known, independent, and never the same twice in a row.
(b) An audit report will be published featuring the steps conducted in a readable format. This should be made available to all Canadians on the exchange website and on a government website. The report must include what percentage of each customer asset is backed on the exchange, and how those funds are stored.
(c) The auditor will independently produce a hash of each customer's identifying information and balance as they perform the audit. This will be made publicly available on the exchange and government website, along with simplified instructions that each customer can use to verify that their balance was included in the audit process.
(d) The audit needs to include a proof of ownership for any cryptocurrency wallets included. A satoshi test (spending a small amount) or partially signed transaction both qualify.
(e) Any platform without 100% reserves should be assessed on a regular basis by a government or industry watchdog. This entity should work to prevent any further drop, support any private investor to come in, or facilitate a merger so that 100% backing can be obtained as soon as possible.
(3) Protections for hot wallets and transactions.
(a) A standardized list of approved coins and procedures will be established to constitute valid cold storage wallets. Where a multi-sig process is not natively available, efforts will be undertaken to establish a suitable and stable smart contract standard. This list will be expanded and improved over time. Coins and procedures not on the list are considered hot wallets.
(b) Hot wallets can be backed by additional funds in cold storage or an acceptable third-party insurance provider with a comprehensive coverage policy.
(c) Exchanges are required to cover the full balance of all user funds as denominated in the same currency, or double the balance as denominated in bitcoin or CAD using an established trading rate. If the balance is ever insufficient due to market movements, the firm must rectify this within 24 hours by moving assets to cold storage or increasing insurance coverage.
(d) Any large transactions (above a set threshold) from cold storage to any new wallet addresses (not previously transacted with) must be tested with a smaller transaction first. Deposits of cryptocurrency must be limited to prevent economic 51% attacks. Any issues are to be covered by the exchange.
(e) Exchange platforms must provide suitable authentication for users, including making available approved forms of two-factor authentication. SMS-based authentication is not to be supported. Withdrawals must be blocked for 48 hours in the event of any account password change. Disputes on the negligence of exchanges should be governed by case law.

Steps Forward

Continued review of existing OSC feedback is still underway. More feedback and opinions on the framework and ideas as presented here are extremely valuable. The above is a draft and not finalized.
The process of further developing and bringing a suitable framework to protect Canadians will require the support of exchange operators, legal experts, and many others in the community. The costs of not doing such are tremendous. A large and convoluted framework, one based on flawed ideas or implementation, or one which fails to properly safeguard Canadians is not just extremely expensive and risky for all Canadians, severely limiting to the credibility and reputation of the industry, but an existential risk to many exchanges.
The responsibility falls to all of us to provide our insight and make our opinions heard on this critical matter. Please take the time to give your thoughts.

ColossusXT Q2 2020 AMA Ends!

Thank you for being a part of the ColossusXT Q2 2020 AMA! Below we will summarize the questions and answers. The team responded to 46 questions! If your question was not included, it may have been answered in a previous question or AMA. The ColossusXT team will do a Reddit AMA at the end of every quarter.
The winner of the AMA contest is: ookhimself
Congratulations. I will send you a DM on Reddit.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Why does your blockchain exist and what makes it unique?
A: ColossusXT exists to provide an energy-efficient method of supercomputing. ColossusXT is unique in many ways. Some coins have 1 layer of privacy. ColossusXT and the Colossus Grid will utilize 2 layers of privacy through Obfuscation Zerocoin Protocol, and I2P and these will protect users of the Colossus Grid as they utilize the grid resources. There are also Masternodes and Proof of Stake which both can contribute to reducing 51% attacks, along with instant transactions and zero-fee transactions. This protection is paramount as ColossusXT evolves into the Colossus Grid. Grid Computing will have a pivotal role throughout the world, and what this means is that users will begin to experience the Internet as a seamless computational universe. Software applications, databases, sensors, video, and audio streams-all will be reborn as services that live in cyberspace, assembling, and reassembling themselves on the fly to meet the tasks at hand. Once plugged into the grid, a desktop machine will draw computational horsepower from all the other computers on the grid.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: What is the Colossus Grid?
A: ColossusXT is an anonymous blockchain through obfuscation, along with utilization of I2P (Armis). These features will protect end-user privacy as ColossusXT evolves into the Colossus Grid. The Colossus Grid will connect devices in a peer-to-peer network enabling users and applications to rent the cycles and storage of other users’ machines. This marketplace of computing power and storage will exclusively run on COLX currency. These resources will be used to complete tasks requiring any amount of computation time and capacity, or allow end-users to store data anonymously across the COLX decentralized network. Today, such resources are supplied by entities such as centralized cloud providers which are constrained by closed networks, proprietary payment systems, and hard-coded provisioning operations. Any user ranging from a single PC owner to a large data center can share resources through Colossus Grid and get paid in COLX for their contributions. Renters of computing power or storage space, on the other hand, may do so at low prices compared to the usual market prices because they are only using resources that already exist.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Is there any estimated date for the grid? What will set you apart from the opposition?
A: We are hoping to have something released for the community in Q4 this year. The difference between other competitors is that ColossusXT is putting consumer privacy first and we’re actively in the process of working with federal and state agencies in the United States.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How do you plan to get people to implement the technology? At your current rate of development, when do you foresee a minimum viable product being available?
A: We have been strategically networking with businesses, and we are currently undergoing the verification process in the United States to make bids on federal and state projects. We are working on an MVP and our goal is to have at least a portion of the Colossus Grid ready by Q4 2020.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: When we can expect any use-case for COLX? A company or service that uses COLX for its activities/tasks.
A: We’re aiming for Q4 of this year to have an MVP, throughout 2021 we will be strategically making bids on federal and state contracts in the United States with a goal to expand operations exponentially.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Are there any plans to be listed on the more prominent exchanges e.g binance, kraken?
A: Yes, we have applied to some of these exchanges that are considered Tier 1 or Tier 2 exchanges. Many of them upfront will tell you there are no fees associated with the listing, that is not entirely true most of the time. Regardless, have applied and are awaiting more responses as we move forward. Listing on these exchanges often requires that we cannot announce this information until ColossusXT is live on its platform.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Partnerships are the norm these days in crypto world. Which partnership would you consider feasible, if any, in order to grow the Colossus Grid project?
A: The Colossus Grid is a huge undertaking both in development and business partnerships. We are moving in both these directions strategically. One of the most important partnerships is not really a partnership but approval to bid on state and federal contracts. Working with the governments around the world will be a big part of the Colossus Grid use-case.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: If the ability to annonymise coins is turned off, can CLX still be marketed as a privacy coin? Do we have a date we can start using this feature again?
A: Yes and No. It’s frustrating right now having a lack of privacy for consumers as we don’t see privacy as a feature but a right. EVERY platform online should have some levels of privacy for their consumers, especially as technology continues to evolve and bad actors continue to use your personal information for their own nefarious purposes. Obfuscation will be implemented in the coming weeks, and Armis will follow suit shortly thereafter.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: When can we expect the grid to come out?
A: We are looking at releasing an MVP towards the end of the year. Stay tuned during Q3 and Q4 as we ramp on technical and business developments.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Can you tell the current budget for development work?
A: Much of the development work budget comes from Core team member's disposable income, we also use the self-funding treasury that Masternode owners vote on each month.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Will cold staking be implemented somedays? I like the model of Cardano. Hope you will implement kind of Cardano staking in our wallet. I would love the easiness.
A: ColossusXT staking has been enabled since 2017. We have calculators on the website that will estimate your average staking returns and you can join numerous pools to increase your staking power within the pools. Cold staking is on our radar and will make it into the roadmap when our budget allows us.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Which part of grid technology are you planning first to go live? Storage/RAM/CPU/GPU/all at once? Separately?
A: We will be rolling the Colossus Grid out in two phases. The first phase will be storage, and then we will roll out computing power (RAM/CPU/GPU).
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Is Armis I2P technology in development testphase I mean, I have read something like that… If Armis goes live, will there be some kind of option in deskopt wallet to transfer anonymous or will every transaction be fully anonymous like e.g. monero?
A: We recently had a testing phase with the community earlier this year, there will be another test phase with community participants who sign up. If you’re interested in this stay tuned on our socials and apply when the next testing phase happens All transactions will be fully anonymous behind Armis.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: What programming languate is being used for developing COLX? How well this programming language do you think is more suitable for developing crypto, in comparison with other programing languages?
A: C++ is what we’re using at ColossusXT. Each crypto project is different but with what we're developing at ColossusXT. We are best suited to utilize C++.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: What is the second biggest milestone other than launching the grid network for the team. What do you think of your competition like Golem network?
A: Armis will be a big milestone, and I don’t think we go back to our Polis partnership which allows users in Europe and Mexico (they do plan to expand to the US and other countries) the ability to spend their ColossusXT (COLX) wherever Mastercard is accepted. I don’t think the Golem network is taking consumer privacy far enough, in the blockchain industry I also see a lack of drive to push adoption within the United States. This is likely due to unclear regulations right now. ColossusXT is at the forefront of these issues and we intend to lead blockchain through these somewhat murky waters.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: I don’t have a lot of knowledge about crypto-technology… but are there any risks of sensitive data-hijacks through Colx infrastructure? Will the Colx-grid be available for individuals or only larger corporations, and how would one get access to the computing power?
A: There are always risks with technology. We are doing extensive testing and more testing prior to releasing anything. Consumer privacy is apart of the foundation of what we’re building at ColossusXT and we want to ensure any and all of your personal information is secure and private. As technology evolves, we will be right here evolving with it to ensure that consumer privacy protections are always in place.
The Colossus Grid will be available to anyone with a computer. You will access it through the desktop wallet.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Do you have any new exchange listings planned in the near future?
A: Yes, but unfortunately with these things, every day it’s not something we can often say before the exchange makes their own announcements. If you have certain exchanges that you prefer, do not be shy and tag us on Twitter letting us and the exchange know. You can also reach us everyday at all hours of the day and night on Discord and Telegram.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Given that Colx had no ICO, are we able to ramp development efforts in case we have potential partnership deal on the table?
A: It really depends. We strategically spend every dime we spend on development. We do not like even a single penny to be waisted, so we don’t move as fast as the projects that raised millions of dollars, but we continue moving none the less. Ramping up our development is something we are working on by securing additional funding and we’re currently working on securing funding. 😊
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How is the project development advancing? What are your plans for the next 5 years and what more can we expect from ColossusXT?
A: Our development is continuing on at a steady pace, we’re looking to ramp this up over the next year as the Colossus Grid will take much of our time but we’re excited. Over the next 5 years, you can expect the Colossus Grid to be live in all forms (storage and computing power), Armis will be released and we will share many technical details on how this consumer privacy protection rivals some of the other privacy protections in the blockchain industry. We expect to be verified and approved to work with the agencies in the United States long before then as well and will be aggressively pursuing federal contracts to utilize the computing power of the Colossus Grid. In 5 years, we plan to be a key player not just in the blockchain industry, but throughout the world. If you do not know ColossusXT now, expect to in 5 years or less.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Users often care less about technology, but rather the value of the token. How do you manage to strike a balance between developing the technology and also improving the value of COLX? There are so many privacy coins now, all of them claiming to have better features that ColossusXT. Moving forward, what do the next 10 years look like for ColossusXT in navigating the wave of privacy projects coming. How can ColossusXT continue to shine in the midst of seemingly legit projects that have come to challenge ColossusXT like mimblewimble projects and Monero, Zcoin, ect.?

A: The Colossus Grid and Masternodes will have a strong relationship with each other. When the Colossus Grid goes live we expect the masternode demand to continue to rise. Masternodes are a great incentive mechanism to increase network strength and will play an important role within the Colossus Grid. The more masternodes online, the less available coins in the circulating supply; which we expect will eventually reflect ColossusXT (COLX) coin value.
Over the next 10 years, ColossusXT (COLX) will solidify itself as a key player in the blockchain industry, and outside the blockchain industry. Following our strategic business plans, we intend to be one of the first, if not the first to truly bring government and other businesses into the blockchain industry through the Colossus Grid. Armis will be our defining privacy feature, which we expect in time will begin to be adopted by other projects. --------------------------------------------------------------------------------------------------------------------------------------------------
Q: How have the number of Masternodes (MNs) increased/decreased over time/in the past few years? What proportion (%) of MNs actively take part in Governance? How do you see the number of MNs increasing/decreasing in the next couple of years? Is there a trend upwards or downwards?
Is there a specific number (or range) of MNs the team would like to attain ideally? Is it better to have as many MNs as possible or is there a point at which too many MNs start to have an adverse effect on the performance of the blockchain?
Hope this wasn’t too many questions in one :), Ahmed

A: The number of masternodes in the active network is more or less the same, fluctuating around 200-220. About 40% - 50% of masternodes participate actively in governance (see https://governance.colossusxt.io). We expect a number of masternodes to grow as they will have additional benefits with Colossus Grid (see business plan: http://bit.ly/COLXBPLive).
As the team had no premines, only the dev fund can be used for masternodes which is hard to maintain due to actual budget flow. It’s better to have as many masternodes as possible for the network, there is no adverse effect.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Of all the milestones that $COLX has achieved since your humble beginnings, which do you consider to be the best of it all? What achievements do you feel proud most?
A: It’s often not mentioned but I’m very proud of our partnership with PolisPay, which allows ColossusXT community members to purchase Amazon, Spotify, and other gift cards with ColossusXT (COLX) through the Polis platform. You are also able to spend your COLX anywhere Mastercard is accepted, the card is available only for EU citizens right now and the Polis team hopes to bring in other countries in the future.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: There are problems that can slow down the course of a project such as the emergence of globalization, given the tighter budget, shorter implementation time requirements. My question is, How does $COLX resolve the issue?

A: Given the current situations around the world the Colossus Grid has more value than it ever has, and that value will continue to grow once we have released the Colossus Grid for consumers to share and utilize resources. You can already see from the [email protected] initiative that people are eager to share their computing resources to help researchers simulate different COVID19 simulations. We’ve always worked on a very small budget at ColossusXT starting with 0$ in funding and no pre-mine or ICO/IEO. This project was built for the community by the community, and as of lately we’ve actually been ramping up our business strategies and developments. Since we have all already worked remotely before the COVID19 pandemic, it interestingly allowed us more time to focus and achieve these goals as our day jobs allowed us to spend more time on ColossusXT.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How will you fight with regulators who are trying to stop privacy coins?

A: We have an amazing legal team at ColossusXT, and they are on top of any new law or regulation that comes out. We’re not afraid of regulators and our legal team makes sure that everything we do for ColossusXT is law-abiding. It's time the world stops looking at privacy as a feature and as a right, especially when you read about different applications and platforms using your personal DATA for their benefit. ColossusXT will continue to push this, and we're prepared to lobby this to lawmakers. --------------------------------------------------------------------------------------------------------------------------------------------------
Q: What type of utilities can $COLX give to users over its competitors like GOLM (computation) or STORJ (Data)?

A: The Colossus Grid has some major differences between Golem and Storj. One we’re a privacy-focused project. If you take a look at many of these applications and platforms today, in some way or another you’re giving up personal information, and/or geographic information. ColossusXT is focused on protecting consumer information, we do not look at privacy as a feature, we see privacy as a right, especially in the tech world today.
The second part of this question is that we’re currently in the verification process of registering with the United States federal and state governments so that we can legally bid on federal and state projects and work with different agencies. This will ensure that as the community members are sharing their idle resources, large corporations and businesses are using it. I’m not aware of the mentioned projects being registered in the United States or taking steps to work with the United States government.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How will computing power and storage sharing look like, for an average user (marketplace, program download)? What are you currently working on, when can we expect MVP? TY
A: The marketplace and Colossus Grid will be inside the ColossusXT desktop wallet that you currently have now. The UI/UX will change some to allow the additional settings and tabs that will become available and we’re preparing an MVP right now and we hope to share those details with you over the next few months, ask us again in the Q3 AMA if you haven’t seen anything yet :)
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: What would you say is the $COLX killer feature that sets it apart from the rest of the competition.
A: We believe that Armis is our killer feature. We recently had a beta this year with the community and will be moving forward later this year with Armis. ColossusXT consumers will have their geographic location and IP fully hidden behind the Armis layer for further security and anonymity for the transactions which will also take place in the Colossus Grid resource marketplace in the future.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: I have been a silent follower of $COLX and I must say that I'm truly impressed with how the team has been diligently working on the project. It'd be nice to have the community be part of something like a bounty or a social awareness contest. As this will not only attract more users to the platform but would also strengthen the bond within the community. When can we possibly expect a community project of this level? #spreadthegrid
A: We currently have a Gleam competition ongoing for social awareness, and we just hired a community manager to spread more community awareness and will be rolling on competitions more regularly. Every quarter we have an AMA on Reddit for the community to ask questions, or just gripe at us, and one person each quarter is awarded 100,000 COLX for participating in the AMA. As we deliver our targets and grow, we will shift more funds from development funds to marketing funds to raise further awareness.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: "Our main competitor is crypto adoption. We are all here to make it happen together.", this is quoted from a founder of a known crypto wallet. Do you see competition as something that strengthens the project as a whole or as a possible distraction due to pressure to be at the top of the crypto ecosystem?

A: This is a two scenario situation. Competition is good for ColossusXT, and we look at our main competitor in blockchain as Golem (GNT), having said that though too much competition or sometimes maximalist behavior isn’t good for crypto, many of these projects should be coming together to lobby lawmakers for laws and regulations that are good for the blockchain industry, as this is still an emerging market and the laws and regulations aren’t exactly in place at this time.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: "For people to believe in crypto, they need to understand the tangible benefits it offers to our society.", a remark made by a crypto project in the past. What exactly would be $COLX real life global benefits? And how do you plan on achieving this?
A: ColossusXT vision will be achievable when the Colossus Grid is released. We are currently in the process of registering with state and federal agencies in the United States, once we are registered to work with these agencies we will pursue contracts with the government, cybersecurity firms and colleges all around the United States, and the world to utilize the resources on the Colossus Grid. We’ve already started building business relationships for this very purpose.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: According to you how much time will it take for $COLX to get into mainstream adoption and execute all the plans set for this project?
A: It’s almost impossible to set a timeline on when the world/people will begin to adopt ColossusXT (COLX) and the Colossus Grid. We don’t believe that adoption for ColossusXT will happen before the Colossus Grid is live, and if I gave you an exact timeline for when or how long it will take you for the Colossus Grid to be adopted I would be lying to you, but we are already forming business relationships and making strategic moves to be able to bid, and work with state and federal agencies in the United States.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Does Tokens.net plan any kind of staking ($COLX or other coins)?
A: We will reach out to the tokens.net team and see if they have any plans to allow staking.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How will you try to boost adoption of #COLX, how do you think you will motivate programmers to join opensource project?
A: The Colossus Grid will be available for anyone to use, or share their idle resources for other consumers to use. We will be focusing on providing these resources to state and federal governments, cybersecurity firms, and researchers all across the world. Certainly, we expect some community members to use these resources to mine different PoW cryptocurrencies, but the team at ColossusXT will be focused on bringing in large colleges and universities as well as big cybersecurity businesses that may need supercomputing power at 1/10th of the current prices. Our programmers are our only paid team members, and we pay them at a competitive rate. We’re looking to bring in some more programmers later this year.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Do you have any special development funds for programmers?
A: Sometimes we pay our programmers out of our own pocket, sometimes we pay them in ColossusXT. It really depends on what kind of agreements have been made. We have been aggressively pursuing different funding opportunities throughout 2020 so that we can expand our development team and in the future, we may have incentives to drive programmers into joining our team. Right now we just stick to a competitive pay scale within the industry.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Why Android Wallet Revision hasn't been done? Any problems?
A: The Android wallet revision took some time to be approved in the Google Playstore, but it has been released and live since June 15, 2020.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Whats the second biggest milestone other than the grid network for COLX team?
A: Armis is likely to be considered our second biggest milestone this year, although as I mentioned above this can easily be overshadowed by our Polis partnership which allows you to spend ColossusXT (COLX) anywhere Mastercard is accepted. Although the epay debit card ownership is currently restricted to certain countries (EU zone only), these restrictions will lift in time.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How is COLX team going to contribute to crypto adoption, other than building a robust network?
A: We’re already in the process of verification to work with state and federal agencies. Adoption for blockchain projects isn’t going to move fast. I read a report just a few days ago about how scammers in the crypto industry stole over 2 million dollars worth of crypto just from the “Elon Musk” impersonations on Twitter.
We will continue to build our network, and seek out state and federal agencies as well as private cybersecurity firms that can utilize the Colossus Grid, we’re not just focused on making noise on social media, we intend to make noise throughout the entire world.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Are their industry partners to COLX that are awaiting your network to go live?
A: Yes, although I hesitate to go into too much detail here. We are talking with business leaders.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: The ongoing crisis affected the market badly, making many projects far from their targets. What is $COLX strategy in order to survive and pass through this crisis?
A: I agree it affected the market badly, especially the projects that raised hundreds of millions of dollars in crypto and held it through the entire market correction. ColossusXT strategy is different from those affected, we’ve always had a smaller budget than these large projects. We spend the money we have available very wisely, and we’re not in a hurry to grab something that sounds good without doing our due diligence. We make our moves very strategically.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: I gotta ask, what made $COLX decide to get listed on Tokens.net? What beneficial advantage does $COLX get in doing so? How about Tokens.net?
A: Tokens.Net is one of the best exchanges ColossusXT is listed at the moment in comparison to others in terms of volume.
  1. Tokens.net is one of the most secure and transparent exchanges out there, registered in the UK.
  2. The team behind the exchange has deep roots in the crypto/blockchain space, it was co-founded by Damian Merlak, a crypto-pioneer and co-founder of Bitstamp.
  3. Tokens.net provides free auto-trading tool / Market Making Bot. Their Dynamic Trading Rights concept adds transparency to trading volumes.
  4. They allow the community voting option of only truly decentralized projects after a thorough screening.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Hey everyone! What is the main purpose of the coin $COLX, does it have its own chain or is it some sort of an ERC-20 token? Thank you for the answers.
A: ColossusXT has never been an ERC-20 coin. We have been operating on our own mainnet since 2017. The purpose of ColossusXT (COLX) is to be the native currency of the Colossus Grid. This will allow users to share their idle resources on their computers, and consumers will rent/buy those resources to complete whatever they intend to use them for, from processing large DATA to running scientific simulations, to even mining PoW cryptocurrencies.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: When we can expect any usecase for COLX? A company or service that uses colx for its activities / tasks.
A: There are currently use cases now if your location allows you to utilize the Polis Pay app, or if you have a Polis Pay card you can buy things with ColossusXT (COLX). I myself have tested the card buying gas at a gas station. These are not ColossusXT’s primary focus though and much of our use case will not start until the Colossus Grid is live.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: What pairs will colx have to trade with on tokens.net // Will you connect #COLX with USDT EURS or BTC?
A: ColossusXT will be initially paired with Bitcoin (BTC). If the community would like different pairs, they can certainly request them and we will reach out to tokens.net and work to facilitate requests.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Will you try to convince users to trade on tokens.net if so how will you do it?
A: There is currently a gleam competition for users to sign up and trade on tokens.net. We “shill” tokens.net accordingly through social media to the ColossusXT community, but can’t really convince anyone to use a certain exchange, although we will try to push as many members to tokens.net as we can. We have many masternode holders who reside in the United States and they are not yet allowed to trade on tokens.net.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How will you try to create liquidity for your pairs?
A: We would like to increase the adoption rate with real-world partnerships such as our partnership with PolisPay for the use of gift/debit cards. As the liquidity is linked with the use cases, supply/demand mechanics, we are also preparing to provide additional use cases of COLX for the crypto world in an innovative & pioneering way; for the time being, we can hint this as a side business till we deliver fully operational Colossus Grid.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: How big is a development team of #COLX?
A: The ColossusXT team is probably bigger than some people realize, partly because many of the team members are very private. We have 9 core members, 2 in-house developers, 3 Colossus Grid architects, and 2 Colossus Grid developers.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Do you have some security guys in the team?
A: Yes, although I’m hesitant to share too many personal details about team members. We have core team members who have been working in different fields of IT security for several years.
--------------------------------------------------------------------------------------------------------------------------------------------------
Q: Since #COLX is planning on having some sort of a marketplace where you can take advantage of computing resources and the blockchain as well, are there any plans on introducing smart contracts? Will it help the grid? Is there a place for it?
A: This has been mentioned a few times in the past so it’s something on our radar, it’s currently not in the development timeline as the Colossus Grid is a massive amount of work. There may be a place for it as the blockchain industry evolves, and I can certainly see some cases where a smart contract can add some value to the Colossus Grid.

Questions I have about Bitcoin

Is bitcoin really viable as a peer-to-peer electronic cash?
Due to high transaction costs and slow transaction speeds, how can we ever use bitcoin to purchase, for example, a Sprite and a bag of potato chips at a gas station? If I want to send a micropayment, for example, of 1000 sats on-chain I can pretty much forget about it because no miner will for and the ftransaction hangs out in the memepool indefinitely. I had a lot of hope for lightning network, but I am now starting to have doubts about its long-term success. What happens when someone using lightning wants to settling a microtransaction on the bitcoin blockchain?
How secure is bitcoin really?
Remember when cz binance wanted to people to thank him for not ordering a re-org to recover lost funds? Isn't bitcoin mining dangerously centralized? What if in the future there is a terrorist attack by government or other criminal orgs that involve bombing or burning large bitcoin mining facilities.
Satoshi writes in the white paper that we propose a solution to the double spending problem, but has this really been achieved? Double spends are still possible with a 51% attack, so what solution to double spending has been achieved. Can't large mining pools conspire to attack bitcoin.
These are concerns I have for the long-term viability and intrinsic value of bitcoin.

Let's discuss some of the issues with Nano

Let's talk about some of Nano's biggest issues. I also made a video about this topic, available here: https://youtu.be/d9yb9ifurbg.
00:12 Spam
Issues
Potential Mitigations & Outstanding Issues
01:58 Privacy
Issues
  • Nano has no privacy. It is pseudonymous (like Bitcoin), not anonymous.
Potential Mitigations & Outstanding Issues & Outstanding Issues*
  • Second layer solutions like mixers can help, but some argue that isn't enough privacy.
  • The current protocol design + the computational overhead of privacy does not allow Nano to implement first layer privacy without compromising it's other features (fast, feeless, and scalable transactions).
02:56 Decentralization
Issues
  • Nano is currently not as decentralized as it could be. ~25% of the voting weight is held by Binance.
  • Users must choose representatives, and users don't always choose the best ones (or never choose).
Potential Mitigations & Outstanding Issues
  • Currently 4 unrelated parties (who all have a verifiable interest in keeping the network running) would have to work together to attack the network
  • Unlike Bitcoin, there is no mining or fees in Nano. This means that there is not a strong incentive for emergent centralization from profit maximization and economies of scale. We've seen this firsthand, as Nano's decentralization has increased over time.
  • Nano representative percentages are not that far off from Bitcoin mining pool percentages.
  • In Nano, voting weight can be remotely re-delegated to anyone at any time. This differs from Bitcoin, where consensus is controlled by miners and requires significant hardware investment.
  • The cost of a 51% attack scales with the market cap of Nano.
06:49 Marketing & adoption
Issues
  • The best technology doesn't always win. If no one knows about or uses Nano, it will die.
Potential Mitigations & Outstanding Issues
  • I would argue that the best technology typically does win, but it needs to be best in every way (price, speed, accessbility, etc). Nano is currently in a good place if you agree with that argument.
  • Bitcoin started small, and didn't spend money on marketing. It takes time to build a community.
  • The developers have said they will market more once the protocol is where they want it to be (v20 or v21?).
  • Community marketing initiatives have started to form organically (e.g. Twitter campaigns, YouTube ads, etc).
  • Marketing and adoption is a very difficult problem to solve, especially when you don't have first mover advantage or consistent cashflow.
08:07 Small developer fund
Issues
  • The developer fund only has 3 million NANO left (~$4MM), what happens after that?
Potential Mitigations & Outstanding Issues
  • The goal for Nano is to be an Internet RFC like TCP/IP or SMTP - development naturally slows down when the protocol is in a good place.
  • Nano development is completely open source, so anyone can participate. Multiple developers are now familiar with the Nano protocol.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
  • The developer fund was only ~5% of the supply - compare that to some of the other major cryptocurrencies.
10:08 Node incentives
Issues
  • There are no transaction fees, why would people run nodes to keep the network running?
Potential Mitigations & Outstanding Issues
  • The cost of consensus is so low in Nano that the benefits of the network itself are the incentive: decentralized money with 0 transaction fees that can be sent anywhere in the world nearly instantly. Similar to TCP/IP, email servers, and http servers. Just like Bitcoin full nodes.
  • Paying $50-$100 a month for a high-end node is a lot cheaper for merchants than paying 1-3% in total sales.
  • Businesses and whales that benefit from Nano (exchanges, remittances, merchant services, etc) are incentivized to keep the protocol developed and running.
11:58 No smart contracts
Issues
  • Nano doesn't support smart contracts.
Potential Mitigations & Outstanding Issues
  • Nano's sole goal is to be the most efficient peer-to-peer value transfer protocol possible. Adding smart contracts makes keeping Nano feeless, fast, and decentralized much more difficult.
  • Other solutions (e.g. Ethereum) exist for creating and enforcing smart contracts.
  • Code can still interact with Nano, but not on the first layer in a decentralized matter.
  • Real world smart contract adoption and usage is pretty limited at the moment, but that might not always be the case.
13:20 Price stability
Issues
  • Why would anyone accept or spend Nano if the price fluctuates so much?
  • Why wouldn't people just use a stablecoin version of Nano for sending and receiving money?
Potential Mitigations & Outstanding Issues
  • With good fiat gateways (stable, low fees, etc), you can always buy back the fiat equivalent of what you've spent.
  • The hope is that with enough adoption, people and businesses will eventually skip the fiat conversion and use Nano directly.
  • Because Nano is so fast, volatility is less of an issue. Transactions are confirmed in <10 seconds, and prices change less in that timeframe (vs 10 minutes to hours for Bitcoin).
  • Stablecoins reintroduce trust. Stable against what? Who controls the supply, and how do you get people to adopt them? What happens if the assets they're stable against fail? Nano is pure supply and demand.
  • With worldwide adoption, the market capitalization of Nano would be in the trillions. If that happens, even millions of dollars won't move the price significantly.
15:06 Deflation
Issues
  • Nano's current supply == max supply. Why would people spend Nano today if it could be worth more tomorrow?
  • What happens to principal representatives and voting weight as private keys are lost? How do you know keys are lost?
Potential Mitigations & Outstanding Issues
  • Nano is extremely divisible. 1 NANO is 1030 raw. Since there are no transaction fees, smaller and smaller amounts of Nano could be used to transact, even if the market cap reaches trillions.
  • People will always buy things they need (food, housing, etc).
  • I'm not sure what the plan is to adjust for lost keys. Probably requires more discussion.
Long-term Scalability
Issue
  • Current node software and hardware cannot handle thousands of TPS (low-end nodes fall behind at even 50 TPS).
  • The more representatives that exist, the more vote traffic is required (network bandwidth).
  • Low-end nodes currently slow down the network significantly. Principal representatives waste their resources constantly bootstrapping these weak nodes during network saturation.
Potential Mitigations & Outstanding Issues
  • Even as is, Nano can comfortably handle 50 TPS average - which is roughly the amount of transactions per day PayPal was doing in 2011 with nearly 100 million users.
  • Network bandwidth increases 50% a year.
  • There are some discussions of prioritizing bootstrapping by vote weight to limit the impact of weak nodes.
  • Since Nano uses an account balance system, pruning could drastically reduce storage requirements. You only need current state to keep the network running, not the full transaction history.
  • In the future, vote stapling could drastically reduce bandwidth usage by collecting all representative signatures up front and then only sharing that single aggregate signature.
  • Nano has no artificial protocol-based limits (e.g. block sizes or block times). It scales with hardware.
Obviously there is still a lot of work to be done in some areas, but overall I think Nano is a good place. For people that aren't Nano fans, what are your biggest concerns?

30+ Reasons Why Cryptocurrencies Are Worthless

1)It is possible to change the code through a miner vote or a fork and change the total supply or anything. DASH did it : they reduced the total supply from 84M to 18.9M a few years ago. They could also increase it to 999 Trillions if they wanted to so that millions of DASH are mined every week.

2)You can also fork bitcoin anytime , start over from 0 and claim it's the real bitcoin. (BCH , BSV , BTG , LTC , BCD etc)

3)Why would you pay $10,000 for a digital collectible unit called BTC when you can use BCH or TRX or LTC .. you name it. They work just as fine and cost less. There is no rarity like in gold.

4)Think of any amount you hold in ethereum as a gift card to use smart contracts on the ETH blockchain. Ridiculous. You’d rather hold a wal mart gift card or even simply cash.

5)Private keys may be bruteforced as we speak. Quintillions entries a second. When they’ll have enough bitcoins under control , they could move them all at once instantly.(At least 45,000 ETH have been stolen this way for now through ethereum bandit)SHA 256 is too old , bitcoin is 10 years old , it is not secure enough , quantum computing could potentially break it.

6)And that’s if people don’t find a way to create an infinite amount of coins to sell on exchanges.. it happened with monero , stellar , bitcoin , zcash , zcoin , eos , etc..

proofs :

“Bitcoin , Coindesk : “The Latest Bitcoin Bug Was So Bad, Developers Kept Its Full Details a Secret”an attacker could have actually used it to create new Bitcoin — above the 21 million hard-cap of coin creation — thereby inflating the supply and devaluing current bitcoins.”

Stellar : “Stellar Inflation: Glitch Leads to 2.25 Billion Extra XLM Printed”

Monero : “A bug in the Monero (XMR) wallet software that could enable fake deposits to exchanges has been recently brought to public attention through a Medium post”

Zcoin : Forged coins were created, but not exceeding 1% of the circulating supply. We will release further details on exact numbers when Sigma is released.

EOS : “Hackers Forge Billion EOS Coins to Steal Real Crypto From DEX “

Zcash : “Zcash Team Reveals It Fixed a Catastrophic Coin Counterfeiting Bug” etc..

7)Segwit , and especially Lightning network is a very complex technology and it will inevitably have flaws , bugs , it will be exploited and people will lose money. That alone can cause bitcoin to drop very low levels.

8)Then miners may be losing millions so they will stop mining , blocks may be so slow , almost no transaction will come though , and bitcoin may not have enough time to reach the next difficulty adjustement. This is reffered to as a death spiral. Then every crypto even those with no mining involved may crash hard.

9)Many crypto wallets are unsafe and have already caused people to lose all their investment , including the infamous “parity wallet”.

10)It is NOT trustless. you have to trust the wallet you’re using is not just generating an address controlled by the developper , you have to trust the node the wallet connects to is an honest node , you have to trust a Rogue state or organization with enough computing power will not 51% attack the network. etc..

11)Bitcoin is NOT deflationary. Bitcoins are created every blocks (roughly every 10 minutes) and you wil be dead by the time we reach the 21 million current hard cap.

12)Bitcoin price may artificially be inflated by Tether.

13)It’s an energy waste , an environmental catastrophy.

14)The only usecases are money laundering , tax evasion , gambling , buying on the dark net , evading sanctions and speculation.

15)Governments will ban it if it gets too big , and they have a big incentive to do so , not only for the obscure usecases but also because it threatens the stability of sovereign currencies. Trump could kill bitcoin with one tweet , force fiat exchanges to cease activity.

16)Most cryptos are scams , the rest are just crazy speculative casino investments.

17)It is pyramidal : early adopters intend to profit massively while last comers get crushed. That's not how money works. The overwhelming majority of crypto holders are buying it because they think they will be able to sell it to a higher price later. Money is supposed to be rather stable. That's why the best cryptocurrencies are USDT USDC etc..

18)The very few stores accepting bitcoin always have the real price in the local currency , not in bitcoin. And prices like 0.00456329 BTC are ridiculous !

19)About famous brokers listing bitcoin : they have to meet the demand in order to make money , it doesn't mean they approve it , some even short it (see interactive broker's CEO opinion on bitcoin)

20)People say cash is backed by nothing and losing value slowly , and yes it is very flawed , but there is a whole nation behind it , it's accepted everywhere , you can buy more things with it.

21)Everybody in crypto thinks that there will be a new bullrun and that then , they will sell. But because everybody thinks it will happen , it might not happen. The truth is past performance doesn’t indicate future performance and it is absolutely not guaranteed that there will ever be another bullrun. The markets are unpredictable.

22)Also BTC went from about $0.003 to the price it is today , so don’t think it’s cheap now.

23)There is no recourse if you’re scammed/hacked/made a mistake in the address etc. No chargebacks. But it might be possible to do a rollback (blockchain reorganization) to reverse some transactions. BSV did it.

24)In case of a financial crisis , the speculative assets would crash the most and bitcoin is far from being a non speculative safe heaven ; and governments might ban it to prevent fiat inflation to worsen.

25) Having to write down the private key somewhere or memorize it is a security flaw ! It’s insane to think a system like this will gain mass adoption.

26) The argument saying governments can not ban it because it is decentralized (like they banned drugs) doesn’t work for cryptos. First , drugs are much harder to find and much more expensive and unsafe because of the ban , and people are willing to take the risk because they like it. But if crypto is banned , value will drop too much , and if you can’t sell it for fiat without risking jail , goodluck to find a buyer. Fiat exchanges could close. Banks could terminate every crypto related bank account. And maybe then the mining death spiral would happen and kill all cryptos.

27) Crypto doesn’t exist. It’s like buying air. It’s just virtual collectibles generated by a code. Faguzzi, fugazzi, it’s a whazzie, it’s a whoozie.. it’s a.. fairy dust. It doesn’t exist. It’s never landed. It’s no matter, it’s not on the elemental chart. It… it’s not fucking real!

28) Most brilliant guys have come out and said Bitcoin was a scam or worthless. Including Bill Gates , Warren Buffet , The Wolf Of Wall Street…

29) Inflation is necessary for POW , BTC code will have to be changed to bypass the 21M cap or mining will die ! If BTC code is not changed to allow for miners to be paid reasonably , they will cease mining when the bitcoin block reward gets too low.Even monero understood it ,the code will have to be changed to allow for an infinite bitcoin supply (devaluating all current bitcoins) or the hash will decrease and the security of bitcoin will decrease dramatically and be 51% attacked

30) Don’t mix up blockchain and cryptos. Even blockchain is overrated. But when you hear this or that company is going blockchain , it doesn’t mean they support cryptocurrencies.

31) Craig Wright had a bitcoin mining company with Dave Kleinman (he died) and on january 1 2020 he claims he will be able to access the 1.1M BTC/BCH/BTG from the mining trust. He may or may not dump them on the market , he also said BTC had a fatal flaw and that by 2019 there will be no more BTC.

32) Hacks in cryptos are very common and usually massive. Billions of dollars in crypto have been stolen in the last 6 years. In may 2019 Binance was hacked and lost 7,000 BTC (and it’s far from being the biggest crypto hack).

33) Bitcoin was first. It's an ancient technology. Newer blockchains have privacy, smart contracts, distributed apps and more.Bitcoin is our future? Was the Model T the future of the automobile? (John Mc Afee)

34) IOTA investiguating stolen funds on mainnet. IOTA shuts down the whole network to deal with trinity wallet attack.

35) Compared to bitcoin other cryptos work just as fine and don't waste so much energy.

36 ) Everytime miners disagree on the updates it will create another version of bitcoin : problem of governance and legitimacy.

37) Cryptos are only legitimate if they act as a credit for a redeemable asset like USDT or gold backed coins.


While the native language of the writter is not english , I think you get the point and it doesn't make it any less relevant.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
  • Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with a blockchain network structure, a notion first created by Stuart Haber and W. Scott Stornetta in 1991.
  • Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
  • The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
  • With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.

1. What is Bitcoin (BTC)?

  • Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
  • Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
  • The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
  • The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
  • Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW).
The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer.
Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs.
As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”).
Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so.
With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic.
Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.

The blockchain

Block production

The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979.
With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”).
An illustration of block production in the Bitcoin Protocol is demonstrated below.

https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d

Block time and mining difficulty

Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty.
Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly.
Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.

What are orphan blocks?

In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency.
It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency.
Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted.
The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network.
However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.

3. Bitcoin’s additional features

Segregated Witness (SegWit)

Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017.
SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin.
SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become.
https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e
The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit.
Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade.
Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values.
For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890.
Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid.
This can create many issues, as illustrated in the below example:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
  3. At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID.
Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.

Lightning Network

Lightning Network is a second-layer micropayment solution for scalability.
Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins.
Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ.
A list of curated resources relevant to Lightning Network can be found here.
In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions.
Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel.
https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8
One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel.
However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.

Schnorr Signature upgrade proposal

Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain.
https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4
However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys.
This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block.
https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e
The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually.
Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.

4. Economics and supply distribution

The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years.
As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.
