The collapse of Mt Gox: from 2014 to present - Cryptoline News

$1 billion was transferred in the Bitcoin network with a commission of $3.5

One of the largest transactions in the history of transactions took place in the Bitcoin blockchain.
An unknown sender transferred 88,857 BTC (about $ 1.15 billion) with a commission of 0.00027847 BTC (about $3.5). The transaction was made by one of the largest existing bitcoin wallets.
According to the Whale Alert portal, the address was created on August 7 and belongs to the custodian service of the Xapo wallet. Transfers for similar large amounts were previously made by the Bitfinex ($1.1 billion at the time of transfer) and Binance ($1.26 billion at the time of transfer) exchanges.
A record transaction in Bitcoins was made by the Mt. Gox exchange. In 2011, it transferred 550,000 BTC worth about $1.32 million - today such volume of coins would be estimated at $7 billion.

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.

We recently had the opportunity to interview the VP of ViaBTC Group, Eddie Jiang. ViaBTC Group owns popular crypto exchange CoinEx and ViaBTC Pool. In this interview Eddie discusses being the first exchange to use BCH as the base currency, ViaBTC Pool and integrating with CoinEx, new features and ambassador program, and competing with other exchanges like Binance and Huobi. Please enjoy the interview below.
How come you decided to open up CoinEx to other cryptos other than just BCH?
Eddie Jiang: CoinEx is the world’s first exchange to implement Bitcoin Cash as a base currency. At that time, it was evident that there was a demand for BCH trading markets, and we are the first to explore this opportunity. It also shows our determination to support the BCH’s development.
As CoinEx is developing, our goal becomes bigger and we are aiming at the global market. We need to constantly improve our product diversification to meet the different needs of more users, so we open up to other cryptos. In the past six months, we have listed more than 50 new tokens. Up to now, we have listed 129 cryptos and 313 markets. Besides, in addition to spot trading, CoinEx also supports perpetual contract and other derivatives trading.
How does CoinEx integrate with the ViaBTC Pool?
Eddie Jiang: ViaBTC Group announced a strategic upgrade, which included a new organizational structure, product innovations and service improvements, on 30 May.
As part of the change, the Group has established three dedicated business units (BU): the financial services BU, consisting of ViaBTC mining pool and CoinEx exchange; the infrastructure services BU, including ViaWallet and Blockchain Explorer; and the ecological development BU, focusing on the research and development of public chain technology and the construction of the ecology.
After halving, the combination of mining and finance will become closer and closer. Investing in mining machines is like buying a Bitcoin option. Miners need more flexible financial products to maintain and increase the value of assets, or hedging services. Based on this judgment, the operations of ViaBTC mining pool and CoinEx exchange will be integrated in the future to realize the financial empowerment of the mining pool to meet the diverse financial needs of miners.
Features of this integrated product upgrade can be summarized as: “ The mining pool is the wallet, and the wallet is the transaction.” ViaBTC is the world first mining pool that has a wallet embedded in the mining pool account. Users do not need to transfer the mined coins, and can realize the function of coin exchange within the wallet. For example, they can directly convert the mined coins into USDT to pay electricity bill. What’s more, users can store, deposit and withdraw their revenue, and transfer assets to CoinEx at any time without charge, as well as complete other operations on the exchange, such as purchasing wealth management products for asset preservation and appreciation. In addition, we also provide hedging services. All of the above functions can be completed in one stop in the mining pool, without the need to transfer assets between different platforms.
The exchange empowers the mining pool, and the mining pool will further bring more traffic and resources to the exchange. The two complement each other and development coordinately.
CoinEx has recently added many new features. Can you talk about what new updates were made to the platform and why you made them?
Eddie Jiang: We have always attached great importance to the development of overseas markets since our establishment, and one of our major goals this year is to cover at least 10 different languages speaking markets.
To realize this and to meet the needs of more users worldwide, CoinEx has been continuously optimizing and upgrading its operating strategies, products and services. Our product diversifications are constantly improving. As I said before, we have launched leverage trading, perpetual contract trading, and wealth management products in addition to just spot trading. However, we don’t ignore the importance of spot trading. More mainstream, popular, and high-quality tokens have been listed, and up to now, there are 129 tokens and 313 trading pairs on CoinEx.
During the epidemic, we have never slowed down our development. Lacking of the OTC service has always been a shortage for CoinEx. In March, we partner with Simplex to integrate the first fiat onramp to our platform. People now can buy crypto with their credit cards, which lowers the threshold for more people to enter the crypto world. Moreover, we announced global strategic partnership with Matrixport to provide people with large amount of fiat to crypto needs the OTC service. These newly launched services also help to attract more users.
At the same time, CoinEx has been launched in Arabic, Italian, English, Japanese, Russian, Korean and other 16 languages. Earlier we also carried out product upgrades, making the UI and function sections clearer.
In terms of operations, we launched an upgraded CoinEx Ambassador program in March. To best utilize each ambassador’s personal strengths, there are four categories of CoinEx Ambassador with different responsibilities, namely Referral Ambassador, Marketing Ambassador, Operation Ambassador, and Business Ambassador, which will expand our brand’s exposure and help CoinEx grow into a more international exchange platform.
From March until now CoinEx has seen a 100% increase in user registrations. Why is that and are you able to see where they are coming from?
Eddie Jiang: Because of the efforts mentioned above, in 2020, we’ve seen an exponential increase in activity in just the past few months alone. In this year alone, CoinEx’s daily registered users increased by 100%. These new users mainly come from markets such as the Middle East, Asia Pacific, and more.
Interestingly, we saw an uptick in traffic from the Middle East in March. User growth in Southeast Asia also picked up significantly, newly registered users increased by 133.6% in April.
With Binance, BitMex, Huobi, Bybit, and Deribit, controlling most of the crypto futures and options markets, where do you see CoinEx fitting in? How do you plan to capture market share from these large exchanges?
Eddie Jiang: We won’t compete with others. We focus on ourselves to improve products and our goal is to be better than yesterday.
Our pace is solid and steady, instead of focusing on temporary heat and flow. We have always attached great importance of spot trading, and we are committed to be responsible for users’ investment. We have set up CoinEx Institution, which is dedicated on project research. A listing committee consist of core team members review and vote on projects recommended by the CoinEx Institution. In this way, fraud projects are avoided as much as possible.
Besides, we will focus on niche areas with great potential. For example, Southeast Asia and the Middle East. CoinEx can serve users in those countries well by providing a platform with rich cryptos to trade, and will pay more efforts on refined operations in different countries.
Moreover, CoinEx has a very complete ecosystem. Financial services, infrastructure, and ecological development, the three business units complement each other. The infrastructure BU is our cornerstone and is positioned as a defensive product; the financial service BU is a cash cow and is positioned as an aggressive product; the ecological development BU focuses on the public chain ecology and is the future infrastructure.
What is the geographical breakdown of the CoinEx userbase?
Eddie Jiang: The current proportion of CoinEx’s overseas users has reached 80% of the total registered users, and mainly in Australia, Southeast Asia, North America, Middle East and South Korea.
Do you have plans to focus on any certain jurisdictions? How will you do that?
Eddie Jiang: When we evaluate regions, two things matter: policy and potential.
Whether an exchange’s business expansion in a region is smooth or not largely depends on the region’s policies. If the region is not very friendly towards cryptocurrency or has repeated attitudes, there will be more difficulties and the cost will be much higher.
For a region’s development potential, we need to think about the demand and market development status. South Korea, Southeast Asia, the Middle East and other regions are all areas with good potential for cryptocurrency development. Compared with Europe and America, policy risks in these countries are lower, and the supervision mechanism is relatively complete. The public has a high degree of awareness of cryptocurrencies. Besides, some regions or countries have inflation problems due to political and economic reasons.
CoinEx will continue to focus on the Middle East and South Asia, which are relatively niche. India has just lifted ban on cryptocurrency trading this year, and there are many cryptocurrency investors in Indian. CoinEx can serve them well by providing a platform with rich cryptos to trade. More people in the Middle East are interested cryptos, especially in countries that are subject to economic sanctions or high inflation. For those people, cryptocurrencies are one of the best choices for asset preservation.
Since the CoinEx Ambassador program launched in March, it has been almost three months. We are conducting the second round of ambassador recruitment. This time, we will use the power of ambassadors to expand our recruitment coverage and strive to attract more crypto enthusiasts from all over the world to grow together with CoinEx. Moreover, we will launch the National Expansion plan and leverage on the CoinEx and ViaBTC mining pool resources, to further explore the Russian market. At the market level, we will make more PR efforts in local markets, and start refined operations.
What is CoinEx Chain and CoinEx DEX?
Eddie Jiang: CoinEx Chain is a public chain built on the Tendermint consensus protocol and the Cosmos SDK. It consists of three dedicated public chains parallel to each other. Among these three chains, CoinEx DEX meets the most basic needs of DeFi for token issuance, transfer, and transactions. The Smart Chain is designed to meet the needs of complex financial scenarios and delivers programmable cash. The Privacy Chain facilitates privacy and security.
On November 11, 2019, we took the lead in launching the Mainnet of CoinEx DEX. CoinEx DEX is the world’s first public chain dedicated to decentralized transactions. Users can easily manage their digital assets on it.
CoinEx DEX can fully satisfy the following conditions: users have private keys at their own disposal; transfers and transactions are all completed on-chain, which is 200% transparent and checkable; the issuance, transfer, and transaction of tokens do not require review or permission; the community governance and operation is decentralized, similar to EOS, and validators are introduced to the community ecosystem construction and governance. There are currently 41 validators.
It also has extreme performance. TPS reaches as high as 10,000 and transactions are confirmed within seconds. The transaction fee, 0.0001 US dollars for each transaction, is negligible.
Third, it’s simple and easy to use. The new operation interface design helps beginners get started quickly; with the one-click token issuing module, users only need to fill in a few items to issue tokens; the built-in automated market-making module guarantees liquidity.
How will CoinEx DEX improve the decentralized exchange space that has been unable to gain much adoption?
Eddie Jiang: There are many challenges and difficulties facing centralized exchanges. The first difficulty is security. Security is a huge concern for CEXs. Over the last 10 years, hackers have stolen more than $1.5 billion from centralized exchanges. In fact, research groups estimate that hackers stole somewhere between $950 Million and $1 Billion from centralized exchanges in 2018 alone. There were also incidents of coin thefts in other exchanges in 2019. Many exchanges, such as Mt. Gox, Youbit, were forced to file for bankruptcy and shut down as a result of hacks.
The second is high management costs. Centralized exchanges need to list a large number of cryptocurrencies and each of them have different trading pairs. That entails huge efforts in development and maintenance and, thus, high management costs.
The last is global policies. Cryptocurrency is faced with different regulatory policies in different countries. Every time a centralized exchange enters a country, it needs to adapt itself to local regulatory policies for compliance. This is a holdback for the exchange’s rapid market expansion globally. Such adaptation will also bring a huge learning cost for the exchange team.
Obviously, these problems can be well solved by DEX. CoinEx DEX is a true DEX with full open source and full community governance, as well as without depending on official nodes, websites, wallets, etc. On DEX, users are able to in charge of their own private keys and assets all by themselves. Their assets are more safe and secure. Transfers and transactions are all completed on-chain, which is 200% transparent and checkable; and the issuance, transfer, and transaction of tokens do not require review or permission. What’s more, CoinEx DEX provides a great and convenient user experience.
How will CoinEx Chain and DEX help the crypto industry as a whole?
Eddie Jiang: The public chain is the cornerstone of the blockchain industry. CoinEx Chain has the parallelism of multiple dedicated public chains, each of which performs its own functions, by cross-chaining for both high performance and flexibility.
CoinEx Chain is committed to building the next generation of blockchain financial infrastructure. It is a more complete ecosystem built around the DEX public chain. The DEX public chain is a dedicated public chain developed specifically for token issuance and trading and the biggest improvement on trading speed, so it only supports the necessary functions, not smart contracts.
But smart contracts are the foundation for building more complex financial applications. Outside the DEX public chain, CoinEx Chain also includes a Smart Chain that supports smart contracts.
Moreover, as privacy issues on the current blockchain have been criticized, it is one of the core tasks of CoinEx Chain to safeguard users’ privacy. Similar to the Smart Chain, the Privacy Chain specifically supports transaction privacy protection. With cross-chain circulation, it can improve the privacy characteristic of the entire CoinEx Chain ecosystem.
Nowadays, 1.7 million people in the world have no bank accounts; however, among them, two thirds are smartphone users with huge demands for financial services. The public chain will empower DeFi applications’ development and popularization, not only help more companies to seize the huge market opportunity, but also to bring lasting transformations and improvements in people’s lives.
With so many crypto exchanges, what is the future outlook of CoinEx when it comes to the crypto exchange space?
Eddie Jiang: It has been nearly 3 years since CoinEx has been launched, but it’s quite young for an entrepreneurial team. We have seen too many projects’ failures due to governance issues. CoinEx has a very elite team with high technical and management capabilities. In terms of business, CoinEx has gradually developed with diversified business and a complete ecosystem. It’s clear that the market will still grow very fast in the future, and the market size is still very large. We will continue to improve our products, put more efforts in marketing and operations, as well as look for more high-quality projects, to increase the number of users and transactions on the platform. Lay a solid foundation, and I’m sure the time will come for us to shine.
What updates is the CoinEx team most excited for?
Eddie Jiang: We are very excited about the National Expansion Plan which will be launched later this year. It is an important part in CoinEx’s globalization strategy. We will actively explore some new markets while consolidate the original ones. CoinEx will set aside 10 million US dollars to set up a “Pioneer Fund” to support this plan. This fund will be used to support local cryptocurrency projects and promote the development of the local cryptocurrency communities through investment or cooperation. Our goal this year is to invest in projects and communities that are conducive to expanding the CoinEx ecosystem in countries with high development potential.

Crypto-Powered: Understanding Bitcoin, Ethereum, and DeFi

Crypto-Powered: Understanding Bitcoin, Ethereum, and DeFi
Until one understands the basics of this tech, they won’t be able to grasp or appreciate the impact it has on our digital bank, Genesis Block.
https://reddit.com/link/ho4bif/video/n0euarkifu951/player
This is the second post of Crypto-Powered — a new series that examines what it means for Genesis Block to be a digital bank that’s powered by crypto, blockchain, and decentralized protocols.
---
Our previous post set the stage for this series. We discussed the state of consumer finance and how the success of today’s high-flying fintech unicorns will be short-lived as long as they’re building on legacy finance — a weak foundation that is ripe for massive disruption.
Instead, the future of consumer finance belongs to those who are deeply familiar with blockchain tech & decentralized protocols, build on it as the foundation, and know how to take it to the world. Like Genesis Block.
Today we begin our journey down the crypto rabbit hole. This post will be an important introduction for those still learning about Bitcoin, Ethereum, or DeFi (Decentralized Finance). This post (and the next few) will go into greater detail about how this technology gives Genesis Block an edge, a superpower, and an unfair advantage. Let’s dive in…

Bitcoin: The First Cryptocurrency

There are plenty of online resources to learn about Bitcoin (Coinbase, Binance, Gemini, Naval, Alex Gladstein, Marc Andreessen, Chris Dixon). I don’t wanna spend a lot of time on that here, but let’s do a quick overview for those still getting ramped up.
Cryptocurrency is the most popular use-case of blockchain technology today. And Bitcoin was the first cryptocurrency to be invented.
Bitcoin is the most decentralized of all crypto assets today — no government, company, or third party can control or censor it.
Bitcoin has two primary features (as do most other cryptocurrencies):
  1. Send Value You can send value to anyone, anywhere in the world. Nobody can intercept, delay or stop it — not even governments or financial institutions. Unlike with traditional money transfers or bank wires, there are no layers of middlemen. This results in a process that is much more cost-efficient. Some popular use-cases include remittances and cross-border payments.
  2. Store Value With nothing but a smartphone, you can become your own bank and store your own funds. Nobody can seize your assets. The funds are digital and stored on a blockchain. Your money no longer needs to be stored at a bank, in a vault, or under your mattress. I covered a few inspiring use-cases in a previous post. They include banking the unbanked, protecting assets from government seizure, mitigating the risk of a bank run, and protection against hyperinflation (like what recently happened in Venezuela).
The fact that there are so few things one can do with Bitcoin is one of its greatest strengths.
Its design is simple, elegant, and focused. It has been 10+ years since Satoshi’s white paper and no one has been able to crack or hack the Bitcoin network. With a market cap of $170B, there is plenty of incentive to try.

Public Awareness

A few negative moments in Bitcoin’s history include the collapse of Mt. Gox — which resulted in hundreds of millions of customer funds being stolen — as well as Bitcoin’s role in dark markets like Silk Road — where Bitcoin arguably found its initial userbase.
However, like most breakthrough technology, Bitcoin is neither good nor bad. It’s neutral. People can use it for good or they can use it for evil. Thankfully, it’s being used less and less for illicit activity. Criminals are starting to understand that transactions on a blockchain are public and traceable — it’s exactly the type of system they usually try to avoid. And it’s true, at this point “a lot more” crimes are actually committed with fiat than crypto.
As a result, the perception of bitcoin and cryptocurrency has been changing over the years to a more positive light.
Bitcoin has even started to enter the world of media & entertainment. It’s been mentioned in Hollywood films like Spiderman: Into the Spider-Verse and in songs from major artists like Eminem. It’s been mentioned in countless TV shows like Billions, The Simpsons, Big Bang Theory, Gray’s Anatomy, Family Guy, and more.
As covid19 has ravaged economies and central banks have been printing money, Bitcoin has caught the attention of many legendary Wall Street investors like Paul Tudor Jones, saying that Bitcoin is a great bet against inflation (reminding him of Gold in the 1970s).
Cash App already lets their 25M users buy Bitcoin. It’s rumored that PayPal and Venmo will soon let their 325M users start buying Bitcoin. Bitcoin is by far the most dominant cryptocurrency and is showing no signs of slowing down. For more than a decade it has delivered on its core use-cases — being able to send or store value.
At this point, Bitcoin has very much entered the zeitgeist of modern pop culture — at least in the West.

Ethereum: Programmable Money

When Ethereum launched in 2015, it opened up a world of new possibilities and use-cases for crypto. With Ethereum Smart Contracts (i.e. applications), this exciting new digital money (cryptocurrency) became a lot less dumb. Developers could now build applications that go beyond the simple use-cases of “send value” & “store value.” They could program cryptocurrency to have rules, behavior, and logic to respond to different inputs. And always enforced by code. Additional reading on Ethereum from Linda Xie or Vitalik Buterin.
Because these applications are built on blockchain technology (Ethereum), they preserve many of the same characteristics as Bitcoin: no one can stop, censor or shut down these apps because they are decentralized.
One of the first major use-cases on Ethereum was the ability to mint and create your own token, your own cryptocurrency. Many companies used this as a way to fundraise from the public. This led to the 2017 ICO bubble (Initial Coin Offerings). Some tokens — and the apps/networks they powered — were fascinating and innovative. Most tokens were pointless. And many tokens were outright scams. Additional token reading from Fred Ehrsam, Balaji, and Naval.

Digital Gold Rush

Just as tokens grew in popularity in 2017–2018, so did online marketplaces where these tokens could be bought, sold, and traded. This was a fledgling asset class — the merchants selling picks, axes, and shovels were finally starting to emerge.
I had a front-row seat — both as an investor and token creator. This was the Wild West with all the frontier drama & scandal that you’d expect.
Binance — now the world’s largest crypto exchange —was launched during this time. They along with many others (especially from Asia) made it really easy for speculators, traders, and degenerate gamblers to participate in these markets. Similar to other financial markets, the goal was straightforward: buy low and sell high.
https://preview.redd.it/tytsu5jnfu951.jpg?width=600&format=pjpg&auto=webp&s=fe3425b7e4a71fa953b953f0c7f6eaff6504a0d1
That period left an embarrassing stain on our industry that we’ve still been trying to recover from. It was a period rampant with market manipulation, pump-and-dumps, and scams. To some extent, the crypto industry still suffers from that today, but it’s nothing compared to what it was then.
While the potential of getting filthy rich brought a lot of fly-by-nighters and charlatans into the industry, it also brought a lot of innovators, entrepreneurs, and builders.
The launch and growth of Ethereum has been an incredible technological breakthrough. As with past tech breakthroughs, it has led to a wave of innovation, experimentation, and development. The creativity around tokens, smart contracts, and decentralized applications has been fascinating to witness. Now a few years later, the fruits of those labors are starting to be realized.

DeFi: Decentralized Finance

So as a reminder, tokens are cryptocurrencies. Cryptocurrencies can carry value. And value is a lot like money. Because tokens are natively integrated with Ethereum, it’s been natural for developers to build applications related to financial services — things like lending, borrowing, saving, investing, payments, and insurance. In the last few years, there has been a groundswell of developer momentum building in this area of financial protocols. This segment of the industry is known as DeFi (Decentralized Finance).
https://preview.redd.it/f0sjzqspfu951.png?width=461&format=png&auto=webp&s=8e0a31bf29250fc624918fbd8514b008762f379e
In Q2 of 2020, 97% of all Ethereum activity was DeFi-related. Total DeFi transaction volume has reached $11.5B. The current value locked inside DeFi protocols is approaching $2 Billion (double from a month ago). DeFi’s meteoric growth cannot be ignored.
Most of that growth can be attributed to exciting protocols like Compound, Maker, Synthetix, Balancer, Aave, dYdX, and Uniswap. These DeFi protocols and the financial services they offer are quickly becoming some of the most popular use-cases for blockchain technology today.
https://preview.redd.it/wn3phnkqfu951.png?width=800&format=png&auto=webp&s=02f56caa6b94aa59eadd6e368ef9346ba10c7611
This impressive growth in DeFi certainly hasn’t come without growing pains. Unlike with Bitcoin, there are near-infinite applications one can develop on Ethereum. Sometimes bugs (or typos) can slip through code reviews, testing, and audits — resulting in loss of funds.
Our next post will go much deeper on DeFi.

Wrap Up

I know that for the hardcore crypto people, what we covered today is nothing new. But for those who are still getting up to speed, welcome! I hope this was helpful and that it fuels your interest to learn more.
Until you understand the basics of this technology, you won’t be able to fully appreciate the impact that it has on our new digital bank, Genesis Block. You won’t be able to understand the implications, how it relates, or how it helps.
After today’s post, some of you probably have a lot more questions. What are specific examples or use-cases of DeFi? Why does it need to be on a blockchain? What benefits does it bring to Genesis Block and our users?
In upcoming posts, we answer these questions. Today’s post was just Level 1. It set the foundation for where we’re headed next: even deeper down the crypto rabbit hole.

Technical: A Brief History of Payment Channels: from Satoshi to Lightning Network

Who cares about political tweets from some random country's president when payment channels are a much more interesting and are actually capable of carrying value?
So let's have a short history of various payment channel techs!

Generation 0: Satoshi's Broken nSequence Channels

Because Satoshi's Vision included payment channels, except his implementation sucked so hard we had to go fix it and added RBF as a by-product.
Originally, the plan for nSequence was that mempools would replace any transaction spending certain inputs with another transaction spending the same inputs, but only if the nSequence field of the replacement was larger.
Since 0xFFFFFFFF was the highest value that nSequence could get, this would mark a transaction as "final" and not replaceable on the mempool anymore.
In fact, this "nSequence channel" I will describe is the reason why we have this weird rule about nLockTime and nSequence. nLockTime actually only works if nSequence is not 0xFFFFFFFF i.e. final. If nSequence is 0xFFFFFFFF then nLockTime is ignored, because this if the "final" version of the transaction.
So what you'd do would be something like this:
  1. You go to a bar and promise the bartender to pay by the time the bar closes. Because this is the Bitcoin universe, time is measured in blockheight, so the closing time of the bar is indicated as some future blockheight.
  2. For your first drink, you'd make a transaction paying to the bartender for that drink, paying from some coins you have. The transaction has an nLockTime equal to the closing time of the bar, and a starting nSequence of 0. You hand over the transaction and the bartender hands you your drink.
  3. For your succeeding drink, you'd remake the same transaction, adding the payment for that drink to the transaction output that goes to the bartender (so that output keeps getting larger, by the amount of payment), and having an nSequence that is one higher than the previous one.
  4. Eventually you have to stop drinking. It comes down to one of two possibilities:
    • You drink until the bar closes. Since it is now the nLockTime indicated in the transaction, the bartender is able to broadcast the latest transaction and tells the bouncers to kick you out of the bar.
    • You wisely consider the state of your liver. So you re-sign the last transaction with a "final" nSequence of 0xFFFFFFFF i.e. the maximum possible value it can have. This allows the bartender to get his or her funds immediately (nLockTime is ignored if nSequence is 0xFFFFFFFF), so he or she tells the bouncers to let you out of the bar.
Now that of course is a payment channel. Individual payments (purchases of alcohol, so I guess buying coffee is not in scope for payment channels). Closing is done by creating a "final" transaction that is the sum of the individual payments. Sure there's no routing and channels are unidirectional and channels have a maximum lifetime but give Satoshi a break, he was also busy inventing Bitcoin at the time.
Now if you noticed I called this kind of payment channel "broken". This is because the mempool rules are not consensus rules, and cannot be validated (nothing about the mempool can be validated onchain: I sigh every time somebody proposes "let's make block size dependent on mempool size", mempool state cannot be validated by onchain data). Fullnodes can't see all of the transactions you signed, and then validate that the final one with the maximum nSequence is the one that actually is used onchain. So you can do the below:
  1. Become friends with Jihan Wu, because he owns >51% of the mining hashrate (he totally reorged Bitcoin to reverse the Binance hack right?).
  2. Slip Jihan Wu some of the more interesting drinks you're ordering as an incentive to cooperate with you. So say you end up ordering 100 drinks, you split it with Jihan Wu and give him 50 of the drinks.
  3. When the bar closes, Jihan Wu quickly calls his mining rig and tells them to mine the version of your transaction with nSequence 0. You know, that first one where you pay for only one drink.
  4. Because fullnodes cannot validate nSequence, they'll accept even the nSequence=0 version and confirm it, immutably adding you paying for a single alcoholic drink to the blockchain.
  5. The bartender, pissed at being cheated, takes out a shotgun from under the bar and shoots at you and Jihan Wu.
  6. Jihan Wu uses his mystical chi powers (actually the combined exhaust from all of his mining rigs) to slow down the shotgun pellets, making them hit you as softly as petals drifting in the wind.
  7. The bartender mutters some words, clothes ripping apart as he or she (hard to believe it could be a she but hey) turns into a bear, ready to maul you for cheating him or her of the payment for all the 100 drinks you ordered from him or her.
  8. Steely-eyed, you stand in front of the bartender-turned-bear, daring him to touch you. You've watched Revenant, you know Leonardo di Caprio could survive a bear mauling, and if some posh actor can survive that, you know you can too. You make a pose. "Drunken troll logic attack!"
  9. I think I got sidetracked here.
Lessons learned?

Spilman Channels

Incentive-compatible time-limited unidirectional channel; or, Satoshi's Vision, Fixed (if transaction malleability hadn't been a problem, that is).
Now, we know the bartender will turn into a bear and maul you if you try to cheat the payment channel, and now that we've revealed you're good friends with Jihan Wu, the bartender will no longer accept a payment channel scheme that lets one you cooperate with a miner to cheat the bartender.
Fortunately, Jeremy Spilman proposed a better way that would not let you cheat the bartender.
First, you and the bartender perform this ritual:
  1. You get some funds and create a transaction that pays to a 2-of-2 multisig between you and the bartender. You don't broadcast this yet: you just sign it and get its txid.
  2. You create another transaction that spends the above transaction. This transaction (the "backoff") has an nLockTime equal to the closing time of the bar, plus one block. You sign it and give this backoff transaction (but not the above transaction) to the bartender.
  3. The bartender signs the backoff and gives it back to you. It is now valid since it's spending a 2-of-2 of you and the bartender, and both of you have signed the backoff transaction.
  4. Now you broadcast the first transaction onchain. You and the bartender wait for it to be deeply confirmed, then you can start ordering.
The above is probably vaguely familiar to LN users. It's the funding process of payment channels! The first transaction, the one that pays to a 2-of-2 multisig, is the funding transaction that backs the payment channel funds.
So now you start ordering in this way:
  1. For your first drink, you create a transaction spending the funding transaction output and sending the price of the drink to the bartender, with the rest returning to you.
  2. You sign the transaction and pass it to the bartender, who serves your first drink.
  3. For your succeeding drinks, you recreate the same transaction, adding the price of the new drink to the sum that goes to the bartender and reducing the money returned to you. You sign the transaction and give it to the bartender, who serves you your next drink.
  4. At the end:
    • If the bar closing time is reached, the bartender signs the latest transaction, completing the needed 2-of-2 signatures and broadcasting this to the Bitcoin network. Since the backoff transaction is the closing time + 1, it can't get used at closing time.
    • If you decide you want to leave early because your liver is crying, you just tell the bartender to go ahead and close the channel (which the bartender can do at any time by just signing and broadcasting the latest transaction: the bartender won't do that because he or she is hoping you'll stay and drink more).
    • If you ended up just hanging around the bar and never ordering, then at closing time + 1 you broadcast the backoff transaction and get your funds back in full.
Now, even if you pass 50 drinks to Jihan Wu, you can't give him the first transaction (the one which pays for only one drink) and ask him to mine it: it's spending a 2-of-2 and the copy you have only contains your own signature. You need the bartender's signature to make it valid, but he or she sure as hell isn't going to cooperate in something that would lose him or her money, so a signature from the bartender validating old state where he or she gets paid less isn't going to happen.
So, problem solved, right? Right? Okay, let's try it. So you get your funds, put them in a funding tx, get the backoff tx, confirm the funding tx...
Once the funding transaction confirms deeply, the bartender laughs uproariously. He or she summons the bouncers, who surround you menacingly.
"I'm refusing service to you," the bartender says.
"Fine," you say. "I was leaving anyway;" You smirk. "I'll get back my money with the backoff transaction, and posting about your poor service on reddit so you get negative karma, so there!"
"Not so fast," the bartender says. His or her voice chills your bones. It looks like your exploitation of the Satoshi nSequence payment channel is still fresh in his or her mind. "Look at the txid of the funding transaction that got confirmed."
"What about it?" you ask nonchalantly, as you flip open your desktop computer and open a reputable blockchain explorer.
What you see shocks you.
"What the --- the txid is different! You--- you changed my signature?? But how? I put the only copy of my private key in a sealed envelope in a cast-iron box inside a safe buried in the Gobi desert protected by a clan of nomads who have dedicated their lives and their childrens' lives to keeping my private key safe in perpetuity!"
"Didn't you know?" the bartender asks. "The components of the signature are just very large numbers. The sign of one of the signature components can be changed, from positive to negative, or negative to positive, and the signature will remain valid. Anyone can do that, even if they don't know the private key. But because Bitcoin includes the signatures in the transaction when it's generating the txid, this little change also changes the txid." He or she chuckles. "They say they'll fix it by separating the signatures from the transaction body. They're saying that these kinds of signature malleability won't affect transaction ids anymore after they do this, but I bet I can get my good friend Jihan Wu to delay this 'SepSig' plan for a good while yet. Friendly guy, this Jihan Wu, it turns out all I had to do was slip him 51 drinks and he was willing to mine a tx with the signature signs flipped." His or her grin widens. "I'm afraid your backoff transaction won't work anymore, since it spends a txid that is not existent and will never be confirmed. So here's the deal. You pay me 99% of the funds in the funding transaction, in exchange for me signing the transaction that spends with the txid that you see onchain. Refuse, and you lose 100% of the funds and every other HODLer, including me, benefits from the reduction in coin supply. Accept, and you get to keep 1%. I lose nothing if you refuse, so I won't care if you do, but consider the difference of getting zilch vs. getting 1% of your funds." His or her eyes glow. "GENUFLECT RIGHT NOW."
Lesson learned?

CLTV-protected Spilman Channels

Using CLTV for the backoff branch.
This variation is simply Spilman channels, but with the backoff transaction replaced with a backoff branch in the SCRIPT you pay to. It only became possible after OP_CHECKLOCKTIMEVERIFY (CLTV) was enabled in 2015.
Now as we saw in the Spilman Channels discussion, transaction malleability means that any pre-signed offchain transaction can easily be invalidated by flipping the sign of the signature of the funding transaction while the funding transaction is not yet confirmed.
This can be avoided by simply putting any special requirements into an explicit branch of the Bitcoin SCRIPT. Now, the backoff branch is supposed to create a maximum lifetime for the payment channel, and prior to the introduction of OP_CHECKLOCKTIMEVERIFY this could only be done by having a pre-signed nLockTime transaction.
With CLTV, however, we can now make the branches explicit in the SCRIPT that the funding transaction pays to.
Instead of paying to a 2-of-2 in order to set up the funding transaction, you pay to a SCRIPT which is basically "2-of-2, OR this singlesig after a specified lock time".
With this, there is no backoff transaction that is pre-signed and which refers to a specific txid. Instead, you can create the backoff transaction later, using whatever txid the funding transaction ends up being confirmed under. Since the funding transaction is immutable once confirmed, it is no longer possible to change the txid afterwards.

Todd Micropayment Networks

The old hub-spoke model (that isn't how LN today actually works).
One of the more direct predecessors of the Lightning Network was the hub-spoke model discussed by Peter Todd. In this model, instead of payers directly having channels to payees, payers and payees connect to a central hub server. This allows any payer to pay any payee, using the same channel for every payee on the hub. Similarly, this allows any payee to receive from any payer, using the same channel.
Remember from the above Spilman example? When you open a channel to the bartender, you have to wait around for the funding tx to confirm. This will take an hour at best. Now consider that you have to make channels for everyone you want to pay to. That's not very scalable.
So the Todd hub-spoke model has a central "clearing house" that transport money from payers to payees. The "Moonbeam" project takes this model. Of course, this reveals to the hub who the payer and payee are, and thus the hub can potentially censor transactions. Generally, though, it was considered that a hub would more efficiently censor by just not maintaining a channel with the payer or payee that it wants to censor (since the money it owned in the channel would just be locked uselessly if the hub won't process payments to/from the censored user).
In any case, the ability of the central hub to monitor payments means that it can surveill the payer and payee, and then sell this private transactional data to third parties. This loss of privacy would be intolerable today.
Peter Todd also proposed that there might be multiple hubs that could transport funds to each other on behalf of their users, providing somewhat better privacy.
Another point of note is that at the time such networks were proposed, only unidirectional (Spilman) channels were available. Thus, while one could be a payer, or payee, you would have to use separate channels for your income versus for your spending. Worse, if you wanted to transfer money from your income channel to your spending channel, you had to close both and reshuffle the money between them, both onchain activities.

Poon-Dryja Lightning Network

Bidirectional two-participant channels.
The Poon-Dryja channel mechanism has two important properties:
Both the original Satoshi and the two Spilman variants are unidirectional: there is a payer and a payee, and if the payee wants to do a refund, or wants to pay for a different service or product the payer is providing, then they can't use the same unidirectional channel.
The Poon-Dryjam mechanism allows channels, however, to be bidirectional instead: you are not a payer or a payee on the channel, you can receive or send at any time as long as both you and the channel counterparty are online.
Further, unlike either of the Spilman variants, there is no time limit for the lifetime of a channel. Instead, you can keep the channel open for as long as you want.
Both properties, together, form a very powerful scaling property that I believe most people have not appreciated. With unidirectional channels, as mentioned before, if you both earn and spend over the same network of payment channels, you would have separate channels for earning and spending. You would then need to perform onchain operations to "reverse" the directions of your channels periodically. Secondly, since Spilman channels have a fixed lifetime, even if you never used either channel, you would have to periodically "refresh" it by closing it and reopening.
With bidirectional, indefinite-lifetime channels, you may instead open some channels when you first begin managing your own money, then close them only after your lawyers have executed your last will and testament on how the money in your channels get divided up to your heirs: that's just two onchain transactions in your entire lifetime. That is the potentially very powerful scaling property that bidirectional, indefinite-lifetime channels allow.
I won't discuss the transaction structure needed for Poon-Dryja bidirectional channels --- it's complicated and you can easily get explanations with cute graphics elsewhere.
There is a weakness of Poon-Dryja that people tend to gloss over (because it was fixed very well by RustyReddit):
Another thing I want to emphasize is that while the Lightning Network paper and many of the earlier presentations developed from the old Peter Todd hub-and-spoke model, the modern Lightning Network takes the logical conclusion of removing a strict separation between "hubs" and "spokes". Any node on the Lightning Network can very well work as a hub for any other node. Thus, while you might operate as "mostly a payer", "mostly a forwarding node", "mostly a payee", you still end up being at least partially a forwarding node ("hub") on the network, at least part of the time. This greatly reduces the problems of privacy inherent in having only a few hub nodes: forwarding nodes cannot get significantly useful data from the payments passing through them, because the distance between the payer and the payee can be so large that it would be likely that the ultimate payer and the ultimate payee could be anyone on the Lightning Network.

Future

After LN, there's also the Decker-Wattenhofer Duplex Micropayment Channels (DMC). This post is long enough as-is, LOL. But for now, it uses a novel "decrementing nSequence channel", using the new relative-timelock semantics of nSequence (not the broken one originally by Satoshi). It actually uses multiple such "decrementing nSequence" constructs, terminating in a pair of Spilman channels, one in both directions (thus "duplex"). Maybe I'll discuss it some other time.
The realization that channel constructions could actually hold more channel constructions inside them (the way the Decker-Wattenhofer puts a pair of Spilman channels inside a series of "decrementing nSequence channels") lead to the further thought behind Burchert-Decker-Wattenhofer channel factories. Basically, you could host multiple two-participant channel constructs inside a larger multiparticipant "channel" construct (i.e. host multiple channels inside a factory).
Further, we have the Decker-Russell-Osuntokun or "eltoo" construction. I'd argue that this is "nSequence done right". I'll write more about this later, because this post is long enough.

$1B Bitcoins On The Move: Owner Transfers ~$100M to Bitfinex And Binance In 10 Days

$1B Bitcoins On The Move: Owner Transfers ~$100M to Bitfinex And Binance In 10 Days
This is the third post of a series of articles dedicated to investigate $1B worth of bitcoins (111,114 BTC/BCH/... BXX) that were dormant since 2014 and started moving actively. The BTC coins were originally located at this address (1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a).
The origin of the bitcoins is discussed here.
A deep-dive into the wallet activity was discussed here.
Today, I will focus on the transfer to major exchanges wallets that could indicate that the owner is selling his coins or exchanging it with alts or mixing it to cover his back.
I built a graph in order to deep dive into the transactions originated from the 111,114-BTC wallet and to follow it. This is the resulting graph were red indicates transactions <1 day, yellow <1 month, blue <1 year, green else.

4,421 BTC have been transferred to Binance wallet 1NDyJtNTjmwk5xPNhjgAMu4HDHigtobu1s and the majority of these coins have been transferred in the last 10 days (August 21st - September 2nd).
Here is the list of the transactions:

Surprisingly BTC price was pumping since those funds were starting to be transferred to Bitfinex and Binance wallets (see Binance transactions' list, August 11th)
How do you think this will impact the market?
Do you want me to continue this investigation? If yes let me know what you would want me to focus on.

Near $1B are currently on the move from a Silkroad related wallet

Near $1B are currently on the move from a Silkroad related wallet
It seems that the owner of a huge #SilkRoad related wallet is moving funds actively since 3 days, dividing it in chunks of 100 coins by subwallets.
The original wallet owned 111,114.62 $BTC / $BCH , which is currently valuated ~ $844M (without taking in account other #Bitcoin forks).
Last movements on these subwallets are 4 years and 5 months old (March 9th, 2014).
The chunks have been divided over time to 60,000 coins then to 30,000 / 20,000 / 10,000 / 5,000 / 500 and now 100 coins.
#Bitcoin: https://www.blocktrail.com/BTC/address/1KyJr2L6CN5XhDfv9Sb5q3kjKwFCrRxTLy/transactions
#BitcoinCash: https://www.blocktrail.com/BCC/address/1KyJr2L6CN5XhDfv9Sb5q3kjKwFCrRxTLy/transactions
Does the owner intend selling it on the market soon?

Update 1
For those who asked, the original wallet (1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a) seems to be related to a SilkRoad address per this post: https://bitcointalk.org/index.php?topic=310600.0.
So it's most probably a wallet owned linked to DPR / SilkRoad. Note that this address is still active with 5 transactions executed in 2018 and 13 in 2017, with really small amount of BTC received/sent.
However, I ran some checks and it does not seem to be linked to the DPR seized coins wallet (1FfmbHfnpaZjKFvyi1okTjJJusN455paPH, there's only a 0.001 BTC link between the 2 addresses), so either the FBI did not sold them yet (last auction was in November 2015) or someone else (linked or not to SilkRoad) has access to it .
Finally, if it's not a SilkRoad related wallet the other options are, by descending probability order:
a) a MtGox cold wallet that has been seized or is still owned by MtGox: in fact the wallet funds moved in March 2014 right after MtGox filed for bankruptcy one month earlier in February 2014; these movements dates are really similar to the 200,000 lost coins "found" by Karpeles which moved March 7th, 2014 (1dda0f8827518ce4d1d824bf7600f75ec7e199774a090a947c58a65ab63552e3), just 2 days before the movements on the wallet we are talking about here.
b) a whale wallet since the major part of the 111,111 coins are coming from a very old deposit of 37,421 coins processed on June 21st, 2011 making this an early adopter's wallet (70d46f768b73e50440e41977eb13ab25826137a8d34486958c7d55c5931c6081)
...
z) CSW's wallet ... https://www.scribd.com/document/372445546/Bitcoin-Lawsuit, credits mishax1

Update 2
This amount of $1B in bitcoins that MtGox is going to return to customers looks pretty familiar, it could match the 111,114-coin wallets we are investigating here: https://btcmanager.com/mt-gox-preparing-return-1b-stolen-bitcoin-affected-users/.
But the methodology of transfer does not match in my opinion, it looks that the owner tries to hide the movements by mixing the coins.

Investigating the $1B Bitcoins on the move from a SilkRoad related wallet

Investigating the $1B Bitcoins on the move from a SilkRoad related wallet
2 days ago, I reported that a SilkRoad related wallet containing about $1B worth of Bitcoins (111,114 $BTC and the same amount of $BCH and of other Bitcoin forks) was on the move after 4 years and 5 months of inactivity : https://www.reddit.com/Bitcoin/comments/9bfnff/near_1b_are_currently_on_the_move_from_a_silkroad/

Today, I will dig a little bit more into this wallet activity.

Below you will find a graph representation of the transactions sent over time from the original 111,114-BTC wallet to the most recent wallets which have received some of the coins. Each branch represent a sequence of transactions sent through several wallets.

Red nodes indicate the most recent transactions (< 1 month), blue nodes indicate quite recent ones (<1 year) and green nodes are the older ones ( > 1 year).

https://preview.redd.it/jjhfpb4udhj11.png?width=2233&format=png&auto=webp&s=7a369b73dfbe4601e05608f1aae36aff24a4d52e

  • Picture 2: original coins are currently transferred on Binance wallet, in fact it is a major end-point/aggregate of transactions originated from the 111,114-BTC wallet (1NDyJtNTjmwk5xPNhjgAMu4HDHigtobu1s).
https://preview.redd.it/7novcf2wdhj11.png?width=2222&format=png&auto=webp&s=d0c429674a70bf2baf32c4ecc9c4475a1d43ad7e

https://preview.redd.it/9ungmsexdhj11.png?width=1620&format=png&auto=webp&s=079fcf54605e88debe0cac297e492785b7cc73ed

  • Picture 4: funds are currently actively mixed, you can see a chain of red nodes with no other purpose than transferring n time the coins and splitting/mixing it a bit (3Ah15skNb8R1teRWs6h2Q2vRywkLJWUhhb).​
https://preview.redd.it/9lzr31n0ehj11.png?width=2227&format=png&auto=webp&s=ade9fcf046e86a595e47f8c196df3abcb28866d3

So it's now obvious that the wallet's owner :
  1. is very actively splitting his original 111,114 BTC this past month (a lot of transactions are very recent, see the amount of red nodes on the graph);
  2. some of this funds are currently being sold on Binance (picture 2 and 3);
  3. is very actively in the process of mixing, hiding and making difficult to track his coins (picture 4).
Is the owner going to sell all his coins? How do you think this can impact the market?

Update 1
Following the request of u/btc-reddit, below you will find the graph that marks with red dots the wallets which have been active in the past 24h. At least 88 BTC have been transferred in the last 24h to Binance wallet: 18afibtW5NLMqMwCZD6yt1qhkmEbrfa3QF , 1M2stLGnZGi9XhB2sqTwFfcSfxZhzYKHs6 , 15jFKpCBfHN599TopLPQYdv2aNCRZSUw2r , 1F1EWmLJtYUA1yvDGRBQ6Z6Zjp33ci9EZX , 1M2stLGnZGi9XhB2sqTwFfcSfxZhzYKHs6 ...

​Furthermore, more than 2,980 BTC have been transferred to Binance wallet in August 2018, certainly to be sold or exchanged with other currencies, which represents 3% of the original wallet.
That's more than $20M worth of bitcoin at current price, it definitely can have impacted the overall price this month.
Most of it was sold after August 12th, which corresponds to the start of an increase in Bitcoin price interestingly:

Update 2
​This address is also heavily involved in this graph: 1NyfNYAXZ76VNdvxUUVxdbhWFQGa7QDjTn. It saw 73,673 BTC go through it (only 350 BTC originated from the wallet we are studying here though), in a little bit more than a year.

Update 3
This address 3D83uPnvodCLpwedooiRrLjdQ9pcFVZF32 is part of the graph and is multiplexing a lot of coins, about 175 BTC in small chunks < 1 BTC.​

Update 4
This is a more refined and complete version of the graph (the yellow nodes indicate transactions activity < 1 month). I let you find where is Binance wallet located ;-)
Obvious, isn't it!

$1B bitcoins on the move: MtGox vs SilkRoad origin and BTC price impact discussed
Preamble: it seems that my post was censored and removed on bitcoin... from now I will only publish my articles on btc and crosspost it. Freedom and freespeech matter to me.
--

This is the 4th post of a series of articles dedicated to investigate $1B worth of bitcoins (111,114 BTC/BCH/... BXX) that were dormant since 2014 and started moving actively. The BTC coins were originally located at this address (1933phfhK3ZgFQNLGSDXvqCn32k2buXY8a).
  • The facts that part of this funds (>13%) have been transferred in the past month to Bitfinex, Binance and Bitmex exchanges is discussed here.
  • The origin of the bitcoins was originally discussed here.
  • A deep-dive into the wallet activity was discussed here.

Today I am writing a short update to discuss the origin of the funds and some events that could be related both to this wallet and yesterday's price crash.

Wallet's origin

This question has been discussed a lot by the crypto community in the past year.
Here is a summary of the most probable hypothesis for the 1933p wallet's origin:
  1. a SilkRoad user or DPRs wallet per this post: https://bitcointalk.org/index.php?topic=310600.0
  2. a MtGox cold wallet that has been seized or is still owned by MtGox: in fact the wallet funds moved in March 2014 right after MtGox filed for bankruptcy one month earlier in February 2014; these movements dates are really similar to the 200,000 lost coins "found" by Karpeles which moved March 7th, 2014 (1dda0f8827518ce4d1d824bf7600f75ec7e199774a090a947c58a65ab63552e3), just 2 days before the movements on the wallet we are talking about here.
  3. a whale wallet since the major part of the 111,111 coins are coming from a very old deposit of 37,421 coins processed on June 21st, 2011 making this an early adopter's wallet (70d46f768b73e50440e41977eb13ab25826137a8d34486958c7d55c5931c6081)

Wizsec, a prominent Bitcoin security expert, seems to be pretty sure that the wallet belongs to a MtGox hodler and early investor, who is not a DPR or a SilkRoad user, per his Twitter post: https://twitter.com/wizsecurity/status/1037030003068653569
Finally, Wizsec and I agree that this wallet is not CSW`'s wallet despite it is mentioned in several court documents. Wizsec spent a lot of time debunking CSW's ownership claims earlier this year: https://twitter.com/wizsecurity/status/968337084837781504

What do you think about this wallet origin?
`
BTC price crash

Also, I wanted to report some events that could be related to this 1933p wallet activity:

  • $100M USDT were transferred (reported by u/whalecheetah) while the 1933f wallet owner was in the process of transferring approximately the same amount to several exchanges.
(update) Here is a link provided by u/jesquit: https://www.reddit.com/btc/comments/9cj208/bitcoin_surge_expected_as_100m_tether_goes_to
  • 10,000 BTC buy order was filed last night on Bitmex with 8,030 BTC transferred from a Bitfinex user wallet while the 1933p wallet owner transferred approximately the same amount of BTC to Bitfinex since August, 24th.
(update) Here is the actual BTC transaction: https://www.blocktrail.com/BTC/tx/f2465a1225531d33696380f06034499a52d707f85ee6ae1419885980011f6e25 ,
with its Bitfinex inputs:
1Kr6QSydW9bFQG1mXiPNNu6WpJGmUa9i1g (3,000)
1Kr6QSydW9bFQG1mXiPNNu6WpJGmUa9i1g (2,000)
1Kr6QSydW9bFQG1mXiPNNu6WpJGmUa9i1g (2,000)
1Kr6QSydW9bFQG1mXiPNNu6WpJGmUa9i1g (1,029.98)
and output to Bitmex:
3BMEXqGpG4FxBA1KWhRFufXfSTRgzfDBhJ (10,000).

Was this deal prepared or was the buyer a bitcoin angel?

--
In the light of September 6th price crash, do you think the $100M transferred to the exchanges caused it?

NBA-China Scandal Crashes Nike Sneaker-Backed Crypto Token Price As Reuters reports on Oct. 16, an anonymous trader’s Weibo post from earlier this month had shone a spotlight on an apparent 10% crash in the price of crypto tokens backed by Nike’s Air Jordan sneakers on 55.com, a United States-based exchange. “It’s clear sneaker speculators were pulling money out of the market,” the trader told Reuters. He interpreted the market response in the context of Chinese netizens’ anger over a now-notorious tweet from Houston Rockets general manager Daryl Morey, in which he declared solidarity with anti-government, anti-Beijing protesters in Hong Kong.
Foxconn Founder: Libra Can ‘Converge’ With China’s Digital Currency In Taiwan Terry Gou, Taiwan’s richest man and the founder of manufacturing giant Foxconn, wants the island to roll out the red carpet for Facebook’s Libra cryptocurrency project. In a recent, little-noticed speech, the billionaire and one-time presidential candidate said Taiwan could boost its status as an international financial hub by embracing Libra, rather than approaching the project with skepticism as other governments have done. Gou also suggested the island could connect Libra, if and when it launches, with the digital currency being developed by the People’s Bank of China.
Ex-CFTC Chairman Proposes Digital Dollar, A Government-Sanctioned Blockchain Protocol Former Commodity Futures Trading Commission (CFTC) chairman Christopher Giancarlo, who had parted ways with the regulator this summer, published an article, named “We Sent a Man to the Moon. We Can Send the Dollar to Cyberspace,” stating that Washington should edge out rivals with a regulated platform for trading greenbacks via blockchain. “We propose a digital dollar — a government-sanctioned blockchain protocol, created and maintained by an independent nongovernmental group but administered by banks and other trusted payment organizations,” his words read.
SEC Restarts Clock On Proposed ‘Bitcoin and T-Bills’ ETF According to a public filing published on Oct 15, investment management firm Wilshire Phoenix and NYSE Arca filed an amendment to their ETF proposal earlier this month to address issuance and redemption for the securities and the listing trading of the fund’s shares. Coinbase Custody will act as the custodian for the bitcoin held by the trust, according to the filing. The notice of Oct 15 says Coinbase will provide attestations confirming the amount of Bitcoin it holds within five business days of the trust’s monthly rebalancing, adding a detail not present in the original filing.

Yesterday, we discussed the chances of a possible rebound in bitcoin if it breaks the $8,400 resistance against the US Dollar. However, BTC price struggled to climb above the $8,400 resistance area. As a result, there was a fresh decline below the $8,300 level. Moreover, there was a break below the key $8,200 support area and the 100 hourly simple moving average.
Finally, the price traded below the $8,100 level and formed a new weekly low near $8,062. It is currently consolidating losses above the $8,100 level. Besides, it traded above the 23.6% Fib retracement level of the recent decline from the $8,386 high to $8,062 low. An immediate resistance is near the $8,200 level (the recent key support). The next resistance is near the $8,220 level and the 50% Fib retracement level of the recent decline from the $8,386 high to $8,062 low.
However, the main resistance for bitcoin is near the $8,300 level and the 100 hourly SMA. Furthermore, there is a key declining channel forming with resistance near $8,350 on the hourly chart of the BTC/USD pair. Therefore, a successful break above the channel resistance and a follow through above $8,400 is must for a decent recovery in the near term.
On the downside, there are not many supports up to $8,000. If the bears gain strength, they may perhaps succeed in clearing the $8,000 support area. The next major support is near the $7,800 level, below which the price is likely to head towards the $7,500 zone.

In terms of the 4-hour line, BTC rose and fell yesterday, with a long shadow. There is a big resistance near the $8400 above. It is possible that BTC will continue to move back in a short term. Sex increased. The medium-term trend is still long. As long as the support of 7800 US dollars is kept below, it is difficult for the air force to dominate the panel. Short term below support around $8100. In terms of operation, close to the resistance level can properly stop the surplus, while maintaining the strategy of bargain hunting.

A Beginners Guide to Bitcoin, Blockchain & Cryptocurrency

As cryptocurrency, and blockchain technology become more abundant throughout our society, it’s important to understand the inner workings of this technology, especially if you plan to use cryptocurrency as an investment vehicle. If you’re new to the crypto-sphere, learning about Bitcoin makes it much easier to understand other cryptocurrencies as many other altcoins' technologies are borrowed directly from Bitcoin.
Bitcoin is one of those things that you look into only to discover you have more questions than answers, and right as you’re starting to wrap your head around the technology; you discover the fact that Bitcoin has six other variants (forks), the amount of politics at hand, or that there are over a thousand different cryptocurrencies just as complex if not even more complex than Bitcoin.
We are currently in the infancy of blockchain technology and the effects of this technology will be as profound as the internet. This isn’t something that’s just going to fade away into history as you may have been led to believe. I believe this is something that will become an integral part of our society, eventually embedded within our technology. If you’re a crypto-newbie, be glad that you're relatively early to the industry. I hope this post will put you on the fast-track to understanding Bitcoin, blockchain, and how a large percentage of cryptocurrencies work.

Community Terminology

Altcoin: Short for alternative coin. There are over 1,000 different cryptocurrencies. You’re probably most familiar with Bitcoin. Anything that isn’t Bitcoin is generally referred to as an altcoin.
HODL: Misspelling of hold. Dank meme accidentally started by this dude. Hodlers are much more interested in long term gains rather than playing the risky game of trying to time the market.
TO THE MOON: When a cryptocurrency’s price rapidly increases. A major price spike of over 1,000% can look like it’s blasting off to the moon. Just be sure you’re wearing your seatbelt when it comes crashing down.
FUD: Fear. Uncertainty. Doubt.
FOMO: Fear of missing out.
Bull Run: Financial term used to describe a rising market.
Bear Run: Financial term used to describe a falling market.

What Is Bitcoin?

Bitcoin (BTC) is a decentralized digital currency that uses cryptography to secure and ensure validity of transactions within the network. Hence the term crypto-currency. Decentralization is a key aspect of Bitcoin. There is no CEO of Bitcoin or central authoritative government in control of the currency. The currency is ran and operated by the people, for the people. One of the main development teams behind Bitcoin is blockstream.
Bitcoin is a product of blockchain technology. Blockchain is what allows for the security and decentralization of Bitcoin. To understand Bitcoin and other cryptocurrencies, you must understand to some degree, blockchain. This can get extremely technical the further down the rabbit hole you go, and because this is technically a beginners guide, I’m going to try and simplify to the best of my ability and provide resources for further technical reading.

A Brief History

Bitcoin was created by Satoshi Nakamoto. The identity of Nakamoto is unknown. The idea of Bitcoin was first introduced in 2008 when Nakamoto released the Bitcoin white paper - Bitcoin: A Peer-to-Peer Electronic Cash System. Later, in January 2009, Nakamoto announced the Bitcoin software and the Bitcoin network officially began.
I should also mention that the smallest unit of a Bitcoin is called a Satoshi. 1 BTC = 100,000,000 Satoshis. When purchasing Bitcoin, you don’t actually need to purchase an entire coin. Bitcoin is divisible, so you can purchase any amount greater than 1 Satoshi (0.00000001 BTC).

What Is Blockchain?

Blockchain is a distributed ledger, a distributed collection of accounts. What is being accounted for depends on the use-case of the blockchain itself. In the case of Bitcoin, what is being accounted for is financial transactions.
The first block in a blockchain is referred to as the genesis block. A block is an aggregate of data. Blocks are also discovered through a process known as mining (more on this later). Each block is cryptographically signed by the previous block in the chain and visualizing this would look something akin to a chain of blocks, hence the term, blockchain.
For more information regarding blockchain I’ve provided more resouces below:

What is Bitcoin Mining

Bitcoin mining is one solution to the double spend problem. Bitcoin mining is how transactions are placed into blocks and added onto the blockchain. This is done to ensure proof of work, where computational power is staked in order to solve what is essentially a puzzle. If you solve the puzzle correctly, you are rewarded Bitcoin in the form of transaction fees, and the predetermined block reward. The Bitcoin given during a block reward is also the only way new Bitcoin can be introduced into the economy. With a halving event occurring roughly every 4 years, it is estimated that the last Bitcoin block will be mined in the year 2,140. (See What is Block Reward below for more info).
Mining is one of those aspects of Bitcoin that can get extremely technical and more complicated the further down the rabbit hole you go. An entire website could be created (and many have) dedicated solely to information regarding Bitcoin mining. The small paragraph above is meant to briefly expose you to the function of mining and the role it plays within the ecosystem. It doesn’t even scratch the surface regarding the topic.

How do you Purchase Bitcoin?

The most popular way to purchase Bitcoin through is through an online exchange where you trade fiat (your national currency) for Bitcoin.
Popular exchanges include:
  • Coinbase
  • Kraken
  • Cex
  • Gemini
There’s tons of different exchanges. Just make sure you find one that supports your national currency.

Volatility

Bitcoin and cryptocurrencies are EXTREMELY volatile. Swings of 30% or more within a few days is not unheard of. Understand that there is always inherent risks with any investment. Cryptocurrencies especially. Only invest what you’re willing to lose.

Transaction & Network Fees

Transacting on the Bitcoin network is not free. Every purchase or transfer of Bitcoin will cost X amount of BTC depending on how congested the network is. These fees are given to miners as apart of the block reward.
Late 2017 when Bitcoin got up to $20,000USD, the average network fee was ~$50. Currently, at the time of writing this, the average network fee is $1.46. This data is available in real-time on BitInfoCharts.

Security

In this new era of money, there is no central bank or government you can go to in need of assistance. This means the responsibility of your money falls 100% into your hands. That being said, the security regarding your cryptocurrency should be impeccable. The anonymity provided by cryptocurrencies alone makes you a valuable target to hackers and scammers. Below I’ve detailed out best practices regarding securing your cryptocurrency.

Two-Factor Authentication (2FA)

Two-factor authentication is a second way of authenticating your identity upon signing in to an account. Most cryptocurrency related software/websites will offer or require some form of 2FA. Upon creation of any crypto-related account find the Security section and enable 2FA.

SMS Authentication

The most basic form of 2FA which you are probably most familiar with. This form of authentication sends a text message to your smartphone with a special code that will allow access to your account upon entry. Note that this is not the safest form of 2FA as you may still be vulnerable to what is known as a SIM swap attack. SIM swapping is a social engineering method in which an attacker will call up your phone carrier, impersonating you, in attempt to re-activate your SIM card on his/her device. Once the attacker has access to your SIM card he/she now has access to your text messages which can then be used to access your online accounts. You can prevent this by using an authenticator such as Google Authenticator.

Authenticator

The use of an authenticator is the safest form of 2FA. An authenticator is installed on a seperate device and enabling it requires you input an ever changing six digit code in order to access your account. I recommend using Google Authenticator.
If a website has the option to enable an authenticator, it will give you a QR code and secret key. Use Google Authenticator to scan the QR code. The secret key consists of a random string of numbers and letters. Write this down on a seperate sheet of paper and do not store it on a digital device.
Once Google Authenticator has been enabled, every time you sign into your account, you will have to input a six-digit code that looks similar to this. If you happen to lose or damage the device you have Google Authenticator installed on, you will be locked out of your account UNLESS you have access to the secret key (which you should have written down).

Hardware Wallets

A wallet is what you store Bitcoin and cryptocurrency on. I’ll provide resources on the different type of wallets later but I want to emphasize the use of a hardware wallet (aka cold storage).
Hardware wallets are the safest way of storing cryptocurrency because it allows for your crypto to be kept offline in a physical device. After purchasing crypto via an exchange, I recommend transferring it to cold storage. The most popular hardware wallets include the Ledger Nano S, and Trezor.
Hardware wallets come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key as well as any other sensitive information in a safety deposit box.
I know this all may seem a bit manic, but it is important you take the necessary security precautions in order to ensure the safety & longevity of your cryptocurrency.

Technical Aspects of Bitcoin

TL;DR
  • Address: What you send Bitcoin to.
  • Wallet: Where you store your Bitcoin
  • Max Supply: 21 million
  • Block Time: ~10 minutes
  • Block Size: 1-2 MB
  • Block Reward: BTC reward received from mining.

What is a Bitcoin Address?

A Bitcoin address is what you send Bitcoin to. If you want to receive Bitcoin you’d give someone your Bitcoin address. Think of a Bitcoin address as an email address for money.

What is a Bitcoin Wallet?

As the title implies, a Bitcoin wallet is anything that can store Bitcoin. There are many different types of wallets including paper wallets, software wallets and hardware wallets. It is generally advised NOT to keep cryptocurrency on an exchange, as exchanges are prone to hacks (see Mt. Gox hack).
My preferred method of storing cryptocurrency is using a hardware wallet such as the Ledger Nano S or Trezor. These allow you to keep your crypto offline in physical form and as a result, much more safe from hacks. Paper wallets also allow for this but have less functionality in my opinion.
After I make crypto purchases, I transfer it to my Ledger Nano S and keep that in a safe at home. Hardware wallets also come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key in a safety deposit box.

What is Bitcoins Max Supply?

The max supply of Bitcoin is 21 million. The only way new Bitcoins can be introduced into the economy are through block rewards which are given after successfully mining a block (more on this later).

What is Bitcoins Block Time?

The average time in which blocks are created is called block time. For Bitcoin, the block time is ~10 minutes, meaning, 10 minutes is the minimum amount of time it will take for a Bitcoin transaction to be processed. Note that transactions on the Bitcoin network can take much longer depending on how congested the network is. Having to wait a few hours or even a few days in some instances for a transaction to clear is not unheard of.
Other cryptocurrencies will have different block times. For example, Ethereum has a block time of ~15 seconds.
For more information on how block time works, Prabath Siriwardena has a good block post on this subject which can be found here.

What is Bitcoins Block Size?

There is a limit to how large blocks can be. In the early days of Bitcoin, the block size was 36MB, but in 2010 this was reduced to 1 MB in order to prevent distributed denial of service attacks (DDoS), spam, and other malicious use on the blockchain. Nowadays, blocks are routinely in excess of 1MB, with the largest to date being somewhere around 2.1 MB.
There is much debate amongst the community on whether or not to increase Bitcoin’s block size limit to account for ever-increasing network demand. A larger block size would allow for more transactions to be processed. The con argument to this is that decentralization would be at risk as mining would become more centralized. As a result of this debate, on August 1, 2017, Bitcoin underwent a hard-fork and Bitcoin Cash was created which has a block size limit of 8 MB. Note that these are two completely different blockchains and sending Bitcoin to a Bitcoin Cash wallet (or vice versa) will result in a failed transaction.
Update: As of May 15th, 2018 Bitcoin Cash underwent another hard fork and the block size has increased to 32 MB.
On the topic of Bitcoin vs Bitcoin Cash and which cryptocurrency is better, I’ll let you do your own research and make that decision for yourself. It is good to know that this is a debated topic within the community and example of the politics that manifest within the space. Now if you see community members arguing about this topic, you’ll at least have a bit of background to the issue.

What is Block Reward?

Block reward is the BTC you receive after discovering a block. Blocks are discovered through a process called mining. The only way new BTC can be added to the economy is through block rewards and the block reward is halved every 210,000 blocks (approximately every 4 years). Halving events are done to limit the supply of Bitcoin. At the inception of Bitcoin, the block reward was 50BTC. At the time of writing this, the block reward is 12.5BTC. Halving events will continue to occur until the amount of new Bitcoin introduced into the economy becomes less than 1 Satoshi. This is expected to happen around the year 2,140. All 21 million Bitcoins will have been mined. Once all Bitcoins have been mined, the block reward will only consist of transaction fees.

Technical Aspects Continued

Understanding Nodes

Straight from the Bitcoin.it wiki
Any computer that connects to the Bitcoin network is called a node. Nodes that fully verify all of the rules of Bitcoin are called full nodes.
In other words, full nodes are what verify the Bitcoin blockchain and they play a crucial role in maintaining the decentralized network. Full nodes store the entirety of the blockchain and validate transactions. Anyone can participate in the Bitcoin network and run a full node. Bitcoin.org has information on how to set up a full node. Running a full node also gives you wallet capabilities and the ability to query the blockchain.
For more information on Bitcoin nodes, see Andreas Antonopoulos’s Q&A on the role of nodes.

What is a Fork?

A fork is a divergence in a blockchain. Since Bitcoin is a peer-to-peer network, there’s an overall set of rules (protocol) in which participants within the network must abide by. These rules are put in place to form network consensus. Forks occur when implementations must be made to the blockchain or if there is disagreement amongst the network on how consensus should be achieved.

Soft Fork vs Hard Fork

The difference between soft and hard forks lies in compatibility. Soft forks are backwards compatible, hard forks are not. Think of soft forks as software upgrades to the blockchain, whereas hard forks are a software upgrade that warrant a completely new blockchain.
During a soft fork, miners and nodes upgrade their software to support new consensus rules. Nodes that do not upgrade will still accept the new blockchain.
Examples of Bitcoin soft forks include:
A hard fork can be thought of as the creation of a new blockchain that X percentage of the community decides to migrate too. During a hard fork, miners and nodes upgrade their software to support new consensus rules, Nodes that do not upgrade are invalid and cannot accept the new blockchain.
Examples of Bitcoin hard forks include:
  • Bitcoin Cash
  • Bitcoin Gold
Note that these are completely different blockchains and independent from the Bitcoin blockchain. If you try to send Bitcoin to one of these blockchains, the transaction will fail.

A Case For Bitcoin in a World of Centralization

Our current financial system is centralized, which means the ledger(s) that operate within this centralized system are subjugated to control, manipulation, fraud, and many other negative aspects that come with this system. There are also pros that come with a centralized system, such as the ability to swiftly make decisions. However, at some point, the cons outweigh the pros, and change is needed. What makes Bitcoin so special as opposed to our current financial system is that Bitcoin allows for the decentralized transfer of money. Not one person owns the Bitcoin network, everybody does. Not one person controls Bitcoin, everybody does. A decentralized system in theory removes much of the baggage that comes with a centralized system. Not to say the Bitcoin network doesn’t have its problems (wink wink it does), and there’s much debate amongst the community as to how to go about solving these issues. But even tiny steps are significant steps in the world of blockchain, and I believe Bitcoin will ultimately help to democratize our financial system, whether or not you believe it is here to stay for good.

Final Conclusions

Well that was a lot of words… Anyways I hope this guide was beneficial, especially to you crypto newbies out there. You may have come into this realm not expecting there to be an abundance of information to learn about. I know I didn’t. Bitcoin is only the tip of the iceberg, but now that you have a fundamental understanding of Bitcoin, learning about other cryptocurrencies such as Litecoin, and Ethereum will come more naturally.
Feel free to ask questions below! I’m sure either the community or myself would be happy to answer your questions.
Thanks for reading!
