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.
Typical securities frameworks will cost Canadians millions of dollars (ie Sarbanes-Oxley estimated at $5m USD/yr per firm). Implementation costs of this proposal are significantly cheaper.
Canadians can maintain a diverse set of exchanges, multiple viable business models are still fully supported, and innovation is encouraged while keeping Canadians safe.
Many of you have limited time to read the full proposal, so here are the highlights:
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.
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.
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.
Will China/USA/Europe ban the use of Bitcoin and traditional cryptocurrencies (including privacy coins) after they introduce their own state-controlled Central Bank Digital Currencies? Will they use fear, fake news of crime to justify this? They want to control money, they want data. Will they first cripple these currencies by regulating the shit out of them, assigning different value to coins people they don't like owed at some point? Regulations already started, everyone owning crypto is deanonymized, exchange is heavily controlled, centralized exchanges steal money from people they don't like by "freezing" their accounts. If big cuntries ban real cryptocurrencies, when 25%/50%/75% of all users loose access, how will that fuck with the price? Will people use decentralized networks -- like Tor and I2P -- to have access to crypto? China already bans Tor, and makes it almost impossible to access the network. Hardware and software spies on all of us. China banned the real internet, now Russia wants to follow. Australia tries to ban cryptography, now USA wants to follow, again. What will we do when other cuntries start banning privacy networks? Support decentralization, support free software. Don't let propaganda influence you, don't accept regulations. -gen_server|postsigned|pgp:F778933194DC122F8AD860FE3258E0996EC21CBD|
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.
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:
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:
There’s tons of different exchanges. Just make sure you find one that supports your national currency.
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.
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.
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.
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).
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
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.
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:
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.
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!
Retailers Around The World That Accept Crypto, From Pizza to Travel
News by Cointelegraph: Jinia Shawdagor Earlier on, when Bitcoin (BTC) arrived on the scene, most cryptocurrency enthusiasts held on to their coins, as there were only so many places they could be spent. Nowadays, the list of marketplaces and retailers accepting Bitcoin and other cryptocurrencies is significantly larger, providing crypto enthusiasts with more options for making real-world purchases. After all, with recognizable organizations like Microsoft and Wikipedia now accepting Bitcoin as payment, conversations about Bitcoin and the power of cryptocurrencies are becoming more prominent. Currently, several fast-food restaurants and coffee shops have started accepting Bitcoin as payment. This will likely provide traction for mass adoption as cryptocurrency payments become increasingly commonplace in day-to-day purchases. Granted, there are some jurisdictions that do not consider Bitcoin or any other cryptocurrency as legal tender. Despite this set back, even big tech companies like Facebook are coming up with payment systems that mimic cryptocurrencies. Here are some of the leading retailers, merchants and companies that will let you book flights and hotels, buy coffee or pizza, or even go to space with crypto.
Pay for a burger in Germany with crypto
The German branch of fast-food restaurant chain Burger King now claims to accept Bitcoin as payment for its online orders and deliveries, but this is not the first time Burger King has warmed up to Bitcoin as a form of payment. The company, headquartered in Florida in the United States, had its Russian branch announce in 2017 that it would start accepting Bitcoin payments, but it ultimately did not take off. The global fast-food retailer reports an annual revenue of about $20 billion and serves about 11 million customers around the world. If all its outlets move to accept Bitcoin as payment, cryptocurrency adoption would inevitably spread.
Spend crypto at Starbucks and other places
For crypto payments to gain traction, merchants need to implement systems that enable swift and easy cryptocurrency spending. Starbucks is one of the companies taking advantage of this concept through Flexa, a U.S.-based payment startup that is helping the cafe giant, as well as dozens of other companies, accept cryptocurrency payments. The company developed an app called Spedn that enables crypto holders to make purchases with merchants like Starbucks. The company’s CEO believes that by making cryptocurrencies spendable in the mainstream, commerce will realize the full benefit of blockchain technology all over the world. Crypto enthusiasts in Silicon Valley’s Palo Alto might already be familiar with Coupa Cafe for other reasons apart from its coffee and food. Through its partnership with a Facebook software developer, Coupa Cafe has been accepting Bitcoin as payment since 2013. Reports show that the cafe received a steady stream of Bitcoin revenue as soon as they started implementing crypto payments — a clear sign of how eager its customers were to pay in Bitcoin. Coupa Cafe is among the few physical businesses in Palo Alto that accept Bitcoin at the moment. The cafe owners believe that their collaboration with the Facebook software engineer will create more traction in terms of Bitcoin adoption.
Buy food with crypto
With over 50,000 takeaway restaurants listed on its United Kingdom-based site, OrderTakeaways is one of the surest ways to get a pizza paid for with crypto delivered to your doorstep. The company has been accepting Bitcoin payments for online takeout orders since 2018. And other similar services include the Korean platform Shuttledelivery as well as German-based service Lieferando and its subsidiaries in several other countries. Apart from online orders, crypto can also be spent at a regular Subway restaurants. As early as 2013, several Subway branches started accepting Bitcoin as payment. Now, for a fraction of a Bitcoin, a Subway sandwich can be purchased at select restaurants.
Pay with Bitcoin to tour space
Besides buying food and inexpensive, day-to-day items with crypto, a trip to space can now be bought with Bitcoin. That’s right. Richard Branson’s space tourism company, Virgin Galactic, started accepting Bitcoin as payment as far back as 2013. Although Branson’s predicted date for the first commercial flight has been pushed back several times, the company achieved its first suborbital space flight last year. Perhaps soon, people will be able to tour the moon on crypto’s dime.
Buy jewelry with Bitcoin
A brick-and-mortar American jewelry company called Reeds Jewelers accepts Bitcoin for both its physical and online stores. What’s more, if a purchase is worth more than $25,000, the company provides free armored delivery for safety. Other jewelry companies accepting Bitcoin include Blue Nile Jewelry, Stephen Silver Fine Jewelry and Coaex Jewelry, to name a few. A big advantage of purchasing large ticket items — like a diamond — with crypto is that it makes moving around large amounts of money cheap and effortless. Reports show that more Silicon Valley investors are buying jewelry with Bitcoin. Last year, Stephen Silver Fine Jewelry reported a 20% growth in crypto transactions, leading to a boost in the company’s sales. The company has been accepting Bitcoin since 2014.
Send and redeem gift cards with Bitcoin
Gyft, a digital platform that allows users to buy, send and redeem gift cards, was one of the first merchants enabling cryptocurrency adoption to gain traction in the real world. The mobile gift card app allows Bitcoin to be used to purchase gift cards from several retailers, some of which include Burger King, Subway, Amazon and Starbucks. The company has also partnered with popular crypto exchange Coinbase to enable users to buy gift cards from their Coinbase wallets.
Travel and pay in Bitcoin
If a traveler only has Bitcoin at their disposal, the following merchants will gladly offer services in exchange for it. TravelbyBit, a flight and hotel booking service, accepts cryptocurrencies like Bitcoin, Binance Coin and Litecoin (LTC) as payment. With a network of over 300 crypto-friendly merchants, the platform is one of the biggest supporters of crypto adoption. TravelbyBit can also alert you to upcoming blockchain events in order to interact with other crypto enthusiasts from around the globe. Other platforms to book flights with crypto include Destinia, CheapBizClass, CheapAir, AirBaltic, Bitcoin.Travel and ABitSky, among others.
Use crypto to book a five-star hotel in Zurich
If ever one finds themselves traveling to Zurich Switzerland, either BTC or Ether (ETH) can be used to pay for a stay in a five-star hotel in Zurich. In May 2019, five-star hotel and spa Dodler Grand announced that it will start accepting Bitcoin and Ether as payment. The hotel has partnered with a fintech firm Inacta as well as Bity (a Swiss-based crypto exchange) to facilitate the payment and conversion of crypto to fiat money. The hotel boasts an amazing view of the Swiss landscape among other enticing amenities that come with a five-star hotel.
Pay for electronics and more with crypto
For all the gadget lovers, there are a bunch of platforms that allow electronic purchases with cryptocurrency. Newegg, for instance, is an electronic retail giant that uses BitPay to process payments made with digital currencies. Even though one cannot get refunds for Bitcoin purchases, Newegg has a good reputation for quality items. Plus, the company boasts its being among the first merchants to support cryptocurrency adoption. Other platforms for gadget junkies include Eyeboot (a platform that sells crypto mining rigs in exchange for crypto), Microsoft, FastTech and Alza (a U.K.-based online store that sells phones and beauty products).
An ever-expanding list
It seems clear that more retailers are warming up to the idea of accepting cryptocurrencies. There is still a long way to go before full adoption can be achieved, but many companies have nevertheless benefited from being early adopters. Despite the volatile price movements of cryptocurrencies, all evidence points to a future cashless society that uses digital currencies, and crypto is leading the way.
Hashrate: went from 54 to 76 PH/s, the low was 50 and the new all-time high is 100 PH/s. BeePool share rose to ~50% while F2Pool shrank to 30%, followed by coinmine.pl at 5% and Luxor at 3%. Staking: 30-day average ticket price is 95.6 DCR (+3.0) as of Sep 3. During the month, ticket price fluctuated between a low of 92.2 and high of 100.5 DCR. Locked DCR represented between 3.8 and 3.9 million or 46.3-46.9% of the supply. Nodes: there are 217 public listening and 281 normal nodes per dcred.eu. Version distribution: 2% at v1.4.0(pre) (dev builds), 5% on v1.3.0 (RC1), 62% on v1.2.0 (-5%), 22% on v1.1.2 (-2%), 6% on v1.1.0 (-1%). Almost 69% of nodes are v.1.2.0 and higher and support client filters. Data snapshot of Aug 31.
Obelisk posted 3 email updates in August. DCR1 units are reportedly shipping with 1 TH/s hashrate and will be upgraded with firmware to 1.5 TH/s. Batch 1 customers will receive compensation for missed shipment dates, but only after Batch 5 ships. Batch 2-5 customers will be receiving the updated slim design. Innosilicon announced the new D9+ DecredMaster: 2.8 TH/s at 1,230 W priced $1,499. Specified shipping date was Aug 10-15. FFMiner DS19 claims 3.1 TH/s for Blake256R14 at 680 W and simultaneously 1.55 TH/s for Blake2B at 410 W, the price is $1,299. Shipping Aug 20-25. Another newly noticed miner offer is this unit that does 46 TH/s at 2,150 W at the price of $4,720. It is shipping Nov 2018 and the stats look very close to Pangolin Whatsminer DCR (which has now a page on asicminervalue).
www.d1pool.com joined the list of stakepools for a total of 16. Australian CoinTreeadded DCR trading. The platform supports fiat, there are some limitations during the upgrade to a new system but also no fees in the "Early access mode". On a related note, CoinTree is working on a feature to pay household bills with cryptocurrencies it supports. Three new OTC desks were added to exchanges page at decred.org. Two mobile wallets integrated Decred:
Coinomiadded Decred to their Android and iOS wallets. In addition to the Apple App Store and Google Play you can download the APK directly. Coinomi features an integrated cryptocurrency exchange and is the first company to offer a mobile Decred wallet.
Reminder: do your best to understand the security and privacy model before using any wallet software. Points to consider: who controls the seed, does the wallet talk to the nodes directly or via middlemen, is it open source or not?
Bit Dialsannounced DCR support via GloBee at their bitdials.eu luxury boutique. Their separate supercar and classic car shop bitcars.eu also accepts DCR, either via GloBee or with manual invoicing in case of privacy concerns.
Targeted advertising report for August was posted by @timhebel. Facebook appeal is pending, some Google and Twitter campaigns were paused and some updated. Read more here. Contribution to the @decredproject Twitter account has evolved over the past few months. A #twitter_ops channel is being used on Matrix to collaboratively draft and execute project account tweets (including retweets). Anyone with an interest in contributing to the Twitter account can ask for an invitation to the channel and can start contributing content and ideas there for evaluation by the Twitter group. As a result, no minority or unilateral veto over tweets is possible. (from GitHub)

The presentations were actually full of very worthwhile information from credible people, articulated aptly to a very government, academic, and corporate crowd, who genuinely took on board valuable insights. Good to know some of these key people are Decred holders and stakers as well. I got to use the entire day to speak directly with some of the most pivotal personalities in this particular populace. Ongoing relationships have been built and strengthened.". (photos: 123)
For those willing to help with the events:
BAB: Hey all, we are gearing up for conference season. I have a list of places we hope to attend but need to know who besides @joshuam and @Haon are willing to do public speaking, willing to work booths, or help out at them? You will need to be well versed on not just what is Decred, but the history of Decred etc... DM me if you are interested. (#event_planning) The Decred project is looking for ambassadors. If you are looking for a fun cryptocurrency to get involved in send me a DM or come talk to me on Decred slack. (@marco_peereboom, longer version here)
One private work channel was successfully migrated to Matrix.
Stylish room avatars were set.
@Haon has prepared a short guide to help new Matrix users get started and join the Decred rooms.
A thread was started to discuss changes to Decred jargon with the intent to make it more consistent and accessible to newcomers. The question whether changing "official" terminology requires stakeholder approval was touched in this thread and in #documentation.
Project fund transparency and constitution were extensively discussed on Reddit and in #general.
Pre-proposal to use Politeia to approve Politeia as a legitimate decision-making tool for Decred.
Reddit: substantive discussion about Decred cons; ecosystem fund; a thread about voter engagement, Politeia UX and trolling; idea of a social media system for Decred by @michae2xl; how profitable is the Obelisk DCR1. Chats: cross-chain trading via LN; plans for contractor management system, lower-level decision making and contractor privacy vs transparency for stakeholders; measuring dev activity; what if the network stalls, multiple implementations of Decred for more resilience, long term vision behind those extensive tests and accurate comments in the codebase; ideas for process for policy documents, hosting them in Pi and approving with ticket voting; about SPV wallet disk size, how compact filters work; odds of a wallet fetching a wrong block in SPV; new module system in Go; security of allowing Android app backups; why PoW algo change proposal must be specified in great detail; thoughts about NIPoPoWs and SPV; prerequisites for shipping SPV by default (continued); Decred vs Dash treasury and marketing expenses, spending other people's money; why Decred should not invade a country, DAO and nation states, entangling with nation state is poor resource allocation; how winning tickets are determined and attack vectors; Politeia proposal moderation, contractor clearance, the scale of proposals and decision delegation, initial Politeia vote to approve Politeia itself; chat systems, Matrix/Slack/Discord/RocketChat/Keybase (continued); overview of Korean exchanges; no breaking changes in vgo; why project fund burn rate must keep low; asymptotic behavior of Decred and other ccs, tail emission; count of full nodes and incentives to run them; Politeia proposal translations and multilingual environment. An unusual event was the chat about double negatives and other oddities in languages in #trading.
DCR started the month at USD 56 / BTC 0.0073 and had a two week decline. On Aug 14 the whole market took a huge drop and briefly went below USD 200 billion. Bitcoin went below USD 6,000 and top 100 cryptos lost 5-30%. The lowest point coincided with Bitcoin dominance peak at 54.5%. On that day Decred dived -17% and reached the bottom of USD 32 / BTC 0.00537. Since then it went sideways in the USD 35-45 / BTC 0.0054-0.0064 range. Around Aug 24, Huobi showed DCR trading volume above USD 5M and this coincided with a minor recovery. @ImacallyouJawdy posted some creative analysis based on ticket data.
StopAndDecrypt published an extensive article "ASIC Resistance is Nothing but a Blockchain Buzzword" that is much in line with Decred's stance on ASICs. The ongoing debates about the possible Sia fork yet again demonstrate the importance of a robust dispute resolution mechanism. Also, we are lucky to have the treasury. Mark B Lundeberg, who found a vulnerability in atomicswap earlier, published a concept of more private peer-to-peer atomic swaps. (missed in July issue) Medium took a cautious stance on cryptocurrencies and triggered at least one project to migrate to Ghost (that same project previously migrated away from Slack). Regulation: Vietnam bans mining equipment imports, China halts crypto events and tightens control of crypto chat groups. Reddit was hacked by intercepting 2FA codes sent via SMS. The announcement explains the impact. Yet another data breach suggests to think twice before sharing any data with any company and shift to more secure authentication systems. Intel and x86 dumpsterfire keeps burning brighter. Seek more secure hardware and operating systems for your coins. Finally, unrelated to Decred but good for a laugh: yetanotherico.com.

The biggest announcement of the month was the new kind of decentralized exchange proposed by @jy-p of Company 0. The Community Discussions section considers the stakeholders' response. dcrd: Peer management and connectivity improvements. Some work for improved sighash algo. A new optimization that gives 3-4x faster serving of headers, which is great for SPV. This was another step towards multipeer parallel downloads – check this issue for a clear overview of progress and planned work for next months (and some engineering delight). As usual, codebase cleanup, improvements to error handling, test infrastructure and test coverage. Decrediton: work towards watching only wallets, lots of bugfixes and visual design improvements. Preliminary work to integrate SPV has begun. Politeia is live on testnet! Useful links: announcement, introduction, command line voting example, example proposal with some votes, mini-guide how to compose a proposal. Trezor: Decred appeared in the firmware update and on Trezor website, currently for testnet only. Next steps are mainnet support and integration in wallets. For the progress of Decrediton support you can track this meta issue. dcrdata: Continued work on Insight API support, see this meta issue for progress overview. It is important for integrations due to its popularity. Ongoing work to add charts. A big database change to improve sorting on the Address page was merged and bumped version to 3.0. Work to visualize agenda voting continues. Ticket splitting: 11-way ticket split from last month has voted (transaction). Ethereum support in atomicswap is progressing and welcomes more eyeballs. decred.org: revamped Press page with dozens of added articles, and a shiny new Roadmap page. decredinfo.com: a new Decred dashboard by lte13. Reddit announcement here. Dev activity stats for June: 245 active PRs, 184 master commits, 25,973 added and 13,575 deleted lines spread across 8 repositories. Contributions came from 2 to 10 developers per repository. (chart)
Hashrate: growth continues, the month started at 15 and ended at 44 PH/s with some wild 30% swings on the way. The peak was 53.9 PH/s. F2Pool was the leader varying between 36% and 59% hashrate, followed by coinmine.pl holding between 18% and 29%. In response to concerns about its hashrate share, F2Pool made a statement that they will consider measures like rising the fees to prevent growing to 51%. Staking: 30-day average ticket price is 94.7 DCR (+3.4). The price was steadily rising from 90.7 to 95.8 peaking at 98.1. Locked DCR grew from 3.68 to 3.81 million DCR, the highest value was 3.83 million corresponding to 47.87% of supply (+0.7% from previous peak). Nodes: there are 240 public listening and 115 normal nodes per dcred.eu. Version distribution: 57% on v1.2.0 (+12%), 25% on v1.1.2 (-13%), 14% on v1.1.0 (-1%). Note: the reported count of non-listening nodes has dropped significantly due to data reset at decred.eu. It will take some time before the crawler collects more data. On top of that, there is no way to exactly count non-listening nodes. To illustrate, an alternative data source, charts.dcr.farm showed 690 reachable nodes on Jul 1. Extraordinary event: 247361 and 247362 were two nearly full blocks. Normally blocks are 10-20 KiB, but these blocks were 374 KiB (max is 384 KiB).
Update from Obelisk: shipping is expected in first half of July and there is non-zero chance to meet hashrate target. Another Chinese ASIC spotted on the web: Flying Fish D18 with 340 GH/s at 180 W costing 2,200 CNY (~340 USD). (asicok.com – translated, also on asicminervalue) dcrASIC team posted a farewell letter. Despite having an awesome 16 nm chip design, they decided to stop the project citing the saturated mining ecosystem and low profitability for their potential customers.
Changenow announced the option to buy DCR with fiat.
TokenPride: "We are seeking feedback on the general setup of our payment processor. We have tried to make it simple and user friendly. 10% of all purchases made in Decred will be donated to the Decred Development fund - and we will be releasing original Decred designs in the future".
BlueYard Capital announced investment in Decred and the intent to be long term supporters and to actively participate in the network's governance. In an overview post they stressed core values of the project:
There are a few other remarkable characteristics that are a testament to the DNA of the team behind Decred: there was no sale of DCR to investors, no venture funding, and no payment to exchanges to be listed – underscoring that the Decred team and contributors are all about doing the right thing for long term (as manifested in their constitution for the project). The most encouraging thing we can see is both the quality and quantity of high calibre developers flocking to the project, in addition to a vibrant community attaching their identity to the project.
The company will be hosting an event in Berlin, see Events below. Arbitrade is now mining Decred.
Campus Party in Brasilia, Brazil. @girino, @Rhama and @matheusd talked about Decred. Matheus was interviewed by a TV channel. Check this quick report about the event, click "Show newer" to continue reading. (photos: 123)
Blockchain Summit in London, UK. This was not a full blown presence with stand but rather investigation of opportunities by @kyle and @Ani. The resulting detailed report is a good example of a document advising to stakeholders whether it is worth spending project funds.
Meetup in Berlin, Germany on July 18. @jz will give a talk and Q&A about Decred and chat with Ele from @oscoin about incentivizing developers. Hosted by BlueYard Capital.
Hey guys! I'd like to share with you my latest adventure: Stakey Club, hosted at stakey.club, is a website dedicated to Decred. I posted a few articles in Brazilian Portuguese and in English. I also translated to Portuguese some posts from the Decred Blog. I hope you like it! (slack)
Decred Assembly - Ep20 - Governance: Driving the Future (youtube) @cburniske and @traceagain discuss the importance of governance protocols being foundational and problems with delegated proof of stake
"I think that developers in the future are going to base their decision on where to build on the basis of governance and community. And so I look for good governance mechanisms and strong communities in blockchains." (@decredproject)

Apples to apples, Decred is 20x more expensive to attack than Bitcoin by Zubair Zia (medium)
What makes Decred different and better from other cryptocurrencies? (cxihub.com)
Community stats: Twitter followers 40,209 (+1,091), Reddit subscribers 8,410 (+243), Slack users 5,830 (+172), GitHub 392 stars and 918 forks of dcrd repository. An update on our communication systems:
Matrix chat logs are nowviewable on the web with the exception of some channels that are not bridged. The new web logs means our chats are now fully public and indexed by search engines.
Slack had an outage on Jun 27 that disturbed communications for a few hours, discussions continued on Decred's bridged platforms.
Jake Yocom-Piatt did an AMA on CryptoTechnology, a forum for serious crypto tech discussion. Some topics covered were Decred attack cost and resistance, voting policies, smart contracts, SPV security, DAO and DPoS. A new kind of DEX was the subject of an extensive discussion in #general, #random, #trading channels as well as Reddit. New channel #thedex was created and attracted more than 100 people. A frequent and fair question is how the DEX would benefit Decred. @lukebp has put it well:
Projects like these help Decred attract talent. Typically, the people that are the best at what they do aren’t driven solely by money. They want to work on interesting projects that they believe in with other talented individuals. Launching a DEX that has no trading fees, no requirement to buy a 3rd party token (including Decred), and that cuts out all middlemen is a clear demonstration of the ethos that Decred was founded on. It helps us get our name out there and attract the type of people that believe in the same mission that we do. (slack)
Another concern that it will slow down other projects was addressed by @davecgh:
The intent is for an external team to take up the mantle and build it, so it won't have any bearing on the current c0 roadmap. The important thing to keep in mind is that the goal of Decred is to have a bunch of independent teams on working on different things. (slack)
A chat about Decred fork resistance started on Twitter and continued in #trading. Community members continue to discuss the finer points of Decred's hybrid system, bringing new users up to speed and answering their questions. The key takeaway from this chat is that the Decred chain is impossible to advance without votes, and to get around that the forker needs to change the protocol in a way that would make it clearly not Decred. "Against community governance" article was discussed on Reddit and #governance. "The Downside of Democracy (and What it Means for Blockchain Governance)" was another article arguing against on-chain governance, discussed here. Reddit recap: mining rig shops discussion; how centralized is Politeia; controversial debate on photos of models that yielded useful discussion on our marketing approach; analysis of a drop in number of transactions; concerns regarding project bus factor, removing central authorities, advertising and full node count – received detailed responses; an argument by insette for maximizing aggregate tx fees; coordinating network upgrades; a new "Why Decred?" thread; a question about quantum resistance with a detailed answer and a recap of current status of quantum resistant algorithms. Chats recap: Programmatic Proof-of-Work (ProgPoW) discussion; possible hashrate of Blake-256 miners is at least ~30% higher than SHA-256d; how Decred is not vulnerable to SPV leaf/node attack.
DCR opened the month at ~$93, reached monthly high of $110, gradually dropped to the low of $58 and closed at $67. In BTC terms it was 0.0125 -> 0.0150 -> 0.0098 -> 0.0105. The downturn coincided with a global decline across the whole crypto market. In the middle of the month Decred was noticed to be #1 in onchainfx "% down from ATH" chart and on this chart by @CoinzTrader. Towards the end of the month it dropped to #3.
Please note: we will not accept any kind of payment to list an asset.
Bithumb got hacked with a $30 m loss. Zcash organized Zcon0, an event in Canada that focused on privacy tech and governance. An interesting insight from Keynote Panel on governance: "There is no such thing as on-chain governance". Microsoft acquired GitHub. There was some debate about whether it is a reason to look into alternative solutions like GitLab right now. It is always a good idea to have a local copy of Decred source code, just in case. Status update from @sumiflow on correcting DCR supply on various sites:
To begin with, none of the below sites were showing the correct supply or market cap for Decred but we've made some progress. coingecko.com, coinlib.io, cryptocompare.com, livecoinwatch.com, worldcoinindex.com - corrected! cryptoindex.co, onchainfx.com - awaiting fix coinmarketcap.com - refused to fix because devs have coins too?

I wrote a 30,000 ft. "executive summary" intro document for cryptos. Not for you, for your non-technical parents or friends.
This document was originally written for my dad, an intelligent guy who was utterly baffled about the cryptocurrency world. The aim was to be extremely concise, giving a broad overview of the industry and some popular coins while staying non-technical. For many of you there will be nothing new here, but recognize that you are in the 0.001% of the population heavily into crypto technology. I've reproduced it for Reddit below, or you can find the original post here on my website. Download the PDF there or hit the direct link: .PDF version. Donations happily accepted:
This document is purely informational. At the time of writing there are over 1000 cryptocurrencies (“cryptos”) in a highly volatile, high risk market. Many of the smaller “altcoins” require significant technical knowledge to store and transact safely. I advise you to carefully scrutinize each crypto’s flavor of blockchain, potential utility, team of developers, and guiding philosophy, before making any investment  decisions. With that out of the way, what follows are brief, extremely high-level summaries of some cryptos which have my interest, listed in current market cap order. But first, some info: Each crypto is a different implementation of a blockchain network. Originally developed as decentralized digital cash, these technologies have evolved into much broader platforms, powering the future of decentralized applications across every industry in the global economy. Without getting into the weeds,  most cryptos work on similar principles: Distributed Ledgers Each node on a blockchain network has a copy of every transaction, which enables a network of trust that eliminates fraud.  Decentralized “Miners” comprise the infrastructure of a blockchain network.  They are monetarily incentivized to add computing power to the network, simultaneously securing and processing each transaction.  Peer-to-peer Cryptos act like digital cash-- they require no third party to transact and are relatively untraceable. Unlike cash, you can back them up. Global Transactions are processed cheaply and instantly, anywhere on Earth. Using cryptos, an African peasant and a San Francisco engineer have the same access to capital, markets, and network services. Secure Blockchains are predicated on the same cryptographic technology that secures your sensitive data and government secrets. They have passed seven years of real-world penetration testing with no failures. 
The first cryptocurrency. As with first movers in any technology, there are associated pros and cons. Bitcoin has by far the strongest brand recognition and deepest market penetration, and it is the only crypto which can be used directly as a currency at over 100,000 physical and web stores around the world. In Venezuela and Zimbabwe, where geopolitical events have created hyperinflation in the centralized fiat currency, citizens have moved to Bitcoin as a de facto transaction standard.  However, Bitcoin unveiled a number of issues that have been solved by subsequent cryptos. It is experiencing significant scaling issues, resulting in high fees and long confirmation times. The argument over potential solutions created a rift in the Bitcoin developer community, who “forked” the network into two separate blockchains amidst drama and politicking in October 2017. Potential solutions to these issues abound, with some already in place, and others nearing deployment. Bitcoin currently has the highest market cap, and since it is easy to buy with fiat currency, the price of many smaller cryptos (“altcoins”) are loosely pegged to its price. This will change in the coming year(s).
Where Bitcoin is a currency, Ethereum is a platform, designed as a foundational protocol on which to develop decentralized applications (“Dapps”). Anyone can write code and deploy their program on the global network for extremely low fees. Just like Twitter wouldn’t exist without the open platform of the internet, the next world-changing Dapp can’t exist without Ethereum. CurrentDapps include a global market for idle computing power and storage, peer-to-peer real estate transactions (no trusted third party for escrow), identity networks for governments and corporations (think digital Social Security card), and monetization strategies for the internet which replace advertising. Think back 10 years to the advent of smartphones, and then to our culture today-- Ethereum could have a similar network effect on humanity. Ethereum is currently the #2 market cap crypto below Bitcoin, and many believe it will surpass it in 2018. It has a large, active group of developers working to solve scaling issues,  maintain security, and create entirely new programming conventions. If successful, platforms like Ethereum may well be the foundation of the decentralized internet of the future.
Ripple is significantly more centralized than most crypto networks, designed as a backbone for the global banking and financial technology (“fintech”) industries. It is a network for exchanging between fiat currencies and other asset classes instantly and cheaply, especially when transacting cross-border and between separate institutions. It uses large banks and remittance companies as “anchors” to allow trading between any asset on the network, and big names like Bank of America, American Express, RBC, and UBS are partners. The utility of this network is global and massive in scale. It is extremely important to note that not all cryptos have the same number of tokens. Ripple has 100 Billion tokens compared to Bitcoin’s 21 Million. Do not directly compare price between cryptos. XRP will likely never reach $1k,  but the price will rise commensurate with its utility as a financial tool. In some sense, Ripple is anathema to the original philosophical vision of this technology space. And while I agree with the cyberpunk notion of decentralized currencies, separation of money and state, this is the natural progression of the crypto world. The internet was an incredible decentralized wild west of Usenet groups and listservs before Eternal September and the dot-com boom, but its maturation affected every part of global society.
Cardano’s main claim to fame: it is the only crypto developed using academic methodologies by a global collective of engineers and researchers, built on a foundation of industry-leading, peer-reviewed cryptographic research. The network was designed from first-principles to allow scalability, system upgrades, and to balance the privacy of its users with the security needs of regulators. One part of this ecosystem is the Cardano Foundation, a Swiss non-profit founded to work proactively with governments and regulatory bodies to institute legal frameworks around the crypto industry. Detractors of Cardano claim that it doesn’t do anything innovative, but supporters see the academic backing and focus on regulation development as uniquely valuable.
Stellar Lumens (XLM)
Stellar Lumens and Ripple were founded by the same person. They initially shared the same code, but today the two are distinct in their technical back-end as well as their guiding philosophy and development goals. Ripple is closed-source, for-profit, deflationary, and intended for use by large financial institutions. Stellar is open-source, non-profit, inflationary, and intended to promote international wealth distribution. As such, they are not direct competitors. IBM is a major partner to Stellar. Their network is already processing live transactions in 12 currency corridors across the South Pacific, with plans to process 60% of all cross-border payments in the South Pacific’s retail foreign exchange corridor by Q2 2018. Beyond its utility as a financial tool, the Stellar network may become a competitor to Ethereum as a platform for application development and Initial Coin Offerings (“ICOs”). The theoretical maximum throughput for the network is higher, and it takes less computational power to run. The Stellar development team is highly active, has written extensive documentation for third-party developers, and has an impressive list of advisors, including Patrick Collison (Stripe), Sam Altman (Y Combinator), and other giants in the software development community.
Iota was developed as the infrastructure backbone for the Internet of Things (IoT), sometimes called the machine economy. As the world of inanimate objects is networked together, their need to communicate grows exponentially. Fridges, thermostats, self-driving cars, printers, planes, and industrial sensors all need a secure protocol with which to transact information. Iota uses a “Tangle” instead of a traditional blockchain, and this is the main innovation driving the crypto’s value. Each device that sends a transaction confirms two other transactions in the Tanlge. This removes the need for miners, and enables unique features like zero fees and infinite scalability. The supply of tokens is fixed forever at 2.8*1015, a staggeringly large number (almost three thousand trillion), and the price you see reported is technically “MIOT”, or the price for a million tokens.
The most successful privacy-focused cryptocurrency. In Bitcoin and most other cryptos, anyone can examine the public ledger and trace specific coins through the network. If your identity can be attached to a public address on that network, an accurate picture of your transaction history can be built-- who, what, and when. Monero builds anonymity into the system using strong cryptographic principles, which makes it functionally impossible to trace coins,  attach names to wallets, or extract metadata from transactions. The development team actively publishes in the cryptography research community. Anonymous transactions are not new-- we call it cash. Only in the past two decades has anonymity grown scarce in the first-world with the rise of credit cards and ubiquitous digital records. Personal data is becoming the most valuable resource on Earth, and there are many legitimate reasons for law-abiding citizens to want digital privacy, but it is true that with anonymity comes bad actors-- Monero is the currency of choice for the majority of black market (“darknet”) transactions. Similarly, US Dollars are the main vehicle for the $320B annual drug trade. An investment here should be based on the underlying cryptographic research and technology behind this coin, as well as competitors like Zcash. 
Zero fees and instantaneous transfer make RaiBlocks extremely attractive for exchange of value, in many senses outperforming Bitcoin at its original intended purpose. This crypto has seen an explosion in price and exposure over the past month, and it may become the network of choice for transferring value within and between crypto exchanges. Just in the first week of 2018: the CEO of Ledger (makers of the most popular hardware wallet on the market) waived the $50k code review fee to get RaiBlocks on his product, and XRB got listed on Binance and Kucoin, two of the largest altcoin exchanges globally. This is one to watch for 2018. 
Developed as a single answer to the problem of supply-chain logistics, VeChain is knocking on the door of a fast-growing $8 trillion industry. Every shipping container and packaged product in the world requires constant tracking and verification. A smart economy for logistics built on the blockchain promises greater efficiency and lower cost through the entire process flow. Don’t take my word for it-- VeChain has investment from PwC (5th largest US corporation), Groupe Renault, Kuehne & Nagel (world’s largest freight company), and DIG (China’s largest wine importer). The Chinese government has mandated VeChain to serve as blockchain technology partner to the city of Gui’an, a special economic zone and testbed for China’s smart city of the future. This crypto has some of the strongest commercial partnerships in the industry, and a large active development team.
“Investment” is a misnomer. Cryptos are traded like securities, but grant you no equity (like trading currency).
It is impossible to double-spend or create a fake transaction, as each ledger is confirmed against every other ledger.
Some utility token blockchains use DAG networks or similar non-linear networks which don’t require mining.
In practice, these are giant warehouses full of specialized computers constantly processing transactions. Miners locate to the cheapest electricity source, and the bulk of mining currently occurs in China.
Centralized second-layer exchange websites have been hacked, but the core technology is untouched.
Detailed write up about EOS. Comments are appreciated.
#1 - What is EOS?
EOS has attained celebrity-like status in the cryptocurrency market - on the back of a very successful ICO, and because it’s seen a healthy rise in its price ever since news of its mainnet hit the markets.
EOS: The Basics
EOS is a decentralised operating system based on blockchain technology. It is designed to support of decentralised applications on a commercial-scale by giving all the required core functionalities. These enable businesses to build the blockchain applications in a manner that stays similar to that of web-based applications. This blockchain network has also claimed to remove transaction fees and conduct millions of transactions within a second.
The token name is EOS.
It has a few major notable tech designs, such as DPoS consensus, 100,000+ TPS, zero transactional fees, ability to alter codes, etc.
At BlockShow Asia, on November 29, 2017, Block.one revealed a publicly available testing environment, known as EOSIO Single-Threaded Application Testnet (EOS STAT).
The entire plan of EOS was published in 2017 in a whitepaper.
The EOSIO platform was developed by a private company, Block.one and was further released as an open-source software on June 1, 2018.
To ensure that the native tokens were distributed widely at the launch of the blockchain, around a billion tokens were sold on the Ethereum platform by Block.one. This provided a distribution network that everyone who owns the token can start using it once the EOS blockchain software is released.
10% of these tokens are reserved for Block.one. Total of 20% EOS tokens was sold on Ethereum in the first 5 days of the entire 341 days long token sale. The remaining 70% tokens, that stand under the majority, are to be sold and produced at market value. The startup, EOS ICO, managed to get $170 million in the first step, regardless of critics from numerous representatives on the blockchain community. EOS is presently the fifth leading cryptocurrency of the world by market capitalization.
#2 - What are the benefits of EOS?
The objective of EOS is to provide a decentralized platform to host applications, implement smart contracts and use blockchain for businesses while hoping to solve the scalability issues faced by pioneering cryptocurrencies such as Bitcoin and Ethereum.
It will also eliminate the fees charged for transactions. It will accomplish this by using delegated proof-of-stake of the consensus protocol as well as by being multi-threaded (being able to run on various computer cores).
The target of EOS is to be the very first operating system that will be decentralized. EOSIO provides a better developmental environment for decentralized applications, such as, BitShares, a platform for the decentralized exchange of cryptocurrency and Steemit, a social networking platform with monetary incentives.
The native token, EOS, is a utility token that gives both storage and the bandwidth on the blockchain. It is proportionate to the entire stake (owning only 1% of EOS tokens permits the usage of up to 1% of the total bandwidth).
These tokens also permit the owner to participate in the on-chain governance of the blockchain and to cast votes, in proportion to the stake of the owner.
The EOSIO platform will drop its vote for 21 block producers at the time of its launch that will further validate and generate blocks within the block time of 500 ms. The smart contract and general language for building the entire platform is WebAssembly (C, C++, Rust) and a portable machine build at World Wide Web Consortium (W3C).
#3 - How to buy and store EOS
How to buy EOS
The EOS coin is listed for trading on various trading exchanges all around the world, and is paired with a few major cryptocurrencies like BTC, ETH, BNB, KRW, and USDT, which is a pro for the user of EOS as this allows the users to access or obtain the EOS token by using their present ETH, BNB, BTC, USDT, or KRW. The entire list of trading exchanges for EOS token includes major global exchanges such as Binance, KuCoin, Bitfinex, Huobi, and more. It has over 120 pairings available across nearly as many exchanges - allowing users to purchase EOS using BTC, ETH, USDT and other major cryptocurrencies.
While cryptocurrency exchanges provide you a platform to buy or sell the EOS cryptocurrency, CoinSwitch, cryptocurrency exchange aggregator comes in to help you make the right decision by providing the prices for EOS on multiple crypto exchanges. It supports more than 140 coins and 45,000 pairs of cryptocurrencies.You can choose whichever pair you want with your token and compare the prices at exchanges. This way you can choose the best deal for you!
What’s more - with CoinSwitch, you do not rely on a separate wallet from the exchange to store your EOS cryptocurrency. Instead, all transactions happen to and from your own personal private wallets.
EOS is an ERC20 token - which means it can be stored on any wallet that supports Ethereum. While this will change once EOS releases its own mainnet, currently a EOS wallet that you can use can be one of the following:
Exodus Wallet is multi-cryptocurrency wallet which has an easy-to-use user interface. It has a built-in exchange that permits you to trade the coin instantly. The backup wizard keeps your wallet ready for later use and safe. It is partially open source wallet.
#4 - What is the future of EOS token?
Trends so far
EOS’s company, Block.one, is registered in Cayman Islands. It began offering EOS tokens to the public in June 2017. It raised $700 million during its ICO - a fairly large amount and a testament to the support it has received from the masses.
An online, wiki-based encyclopedia, Everipedia, has announced its plans for using EOS blockchain technology on 6th December 2017. As soon as the Everipedia is decentralized and hosted on EOSIO platform, few countries such as Iran and Turkey that have blocked Wikipedia, will not be able to block it any further via Everipedia’s fork.
EOS Global Acceptance
The Market Cap ranking of the EOS cryptocurrency is 5th, and it holds a market capitalisation of $10.9 billion USD as of June 2018. A total number of 900 million EOS coins are in circulation.
The EOS platform allows developers to build decentralized applications in a public environment. Above all, scalability can be achieved easily with the help of EOS as it is able to support thousands of commercial decentralized applications thanks to its architecture - which is Proof-of-Stake instead of the slower Proof-of-Work that cryptocurrencies generally use. EOS is gaining more traction day by day.
EOS saw an increase of over 15x between the closing months of 2017 and opening months of 2018 - going from around $1 to over $15. Impressively, despite the decline the market saw in general, the price of an EOS coin continues to however around the $15 mark as of June 2018. This may be supported by news of its upcoming mainnet launch.
The price is intended to get to $37 by the end of 2018, which would also lead to a price of around $143 in the next five years. Hence, the entire quantum of appreciation that can be gained is big enough, which is why it is worth investing in the platform.
Due to multiple decentralized applications, the need for an IT infrastructure for EOS has decreased. With the increase in the number of companies starting to use the platform for decentralized applications, the valuation of the platform will increase too.
#5 - How is EOS different from other cryptocurrencies?
One aspect that makes EOS entirely different and better than all the other cryptocurrencies is that it does not charge any transaction fees.
EOS is a decentralized platform that has room for far higher scalability. While both Ethereum and EOS are platforms that can run smart contracts, EOS claims to offer faster transaction times, and quicker execution. It can further support industrial-scale decentralized applications.
While Ethereum uses a Proof-of-Work (PoW) model for its mining operations, EOS will use a Delegated Proof-Of-Stake (PoS) model for EOS mining - which is far faster, and will not be as energy intensive as mining generally is.
While developers on blockchains typically have to use a specific language to build their applications, EOS allows developers to compile in Web Assembly, which means developers can use C++ to build their applications!
#6 - Should you invest in EOS?
It is likely to be the first third-generation blockchain to reach out to the market.
Unique features: - It has parallel processing that is good for scalability. - It has no transaction fees, block producers paid out by inflation.
There is an inflation build in the token model, which will help the block producers earn incentives when performing their work.
It will also have a process for the recovery of an account if you tend to lose your private keys. It will make human readable account names.
EOS has a massive reserve so far. Due to its initial coin offerings, it has earned billions of dollars. The platform has created a large ecosystem fund with this reserve.
Companies and organizations can easily make decentralized applications with the help of this platform.
The on-chain governance system will lead to more politics, as you need to garner a lot of votes to become one of the block producers.
It may not be as decentralized as say, ETH, as it can have only 21 block producers.
EOS has a lot going for it. This is why it raised over $700 million in its ICO in the first place. You already know how to buy eos coin by now. Whether you should buy and hold, is a decision that will require more deliberation, as with any other cryptocurrency.
BINANCE: A DRIVER FOR BLOCKCHAIN AND CRYPTO-CURRENCY ADOPTION
Introduction Binance is an exchange company formed in 2017. If one may ask, is Binance just an exchange or a progressive crypto exchange? My answer is that Binance is not just a crypto exchange company but an 'engine' that drives crypto-currency adoption. How? My readers may ask. My answers will first start with a simple analogy of what is adoption.
Adoption is a process whereby a person assumes the parenting of another, (usually a child, from that person's biological or legal parent or parents,) and in so doing, permanently transfers all rights and responsibilities, along with filiation, from the biological parent or parents (Wikipedia,2018). In the sense of crypto-currency it is a process whereby a person assumes the parenting of another ( new idea or way or thing) and in so doing permanently transfers all rights and responsibility that belong to the old or normal way to the new way. Driving in the other hand is knowing how to operate the mechanisms which control the system (vehicle); it requires knowing how to apply the rules of the road (which ensures safe and efficient sharing with other users). An effective driver also has an intuitive understanding of the basics of system (vehicle ) handling and can drive responsibly (Jacob,2018). A driver may be a person, company, a system or device that knows the mechanism which control a system and the driver must formulate or know the rules and the basics of directing the system to its target. A device driver for instance is a system (computer program) that operates or controls a particular type of device (EMC,2010). In our case we are looking at crypto-adoption driver, a person or company that knows the mechanism which can be used to make greater number of people to transfer permanently the rights and responsibility of fiat money to blockchain currency (Crypto-currency). A clear case of driving adoption can be easily seen in Football which have been in existence long ago, but FIFA devices a way to entice all nation to participate and develop football infrastructure in there countries by moving Football tournament hosting around different regions and other things they did to make the sports to be popular (adopted) all over the regions of the world. Similarly, crypto-currency have been there before Binance started, crypto-exchanges have been there before the advent of Binance but what Binance did and what they did not do helped in replicating adoption across all the regions of the globe. The only challenge here is whether these position can be substantiated?
The Authors experience My name is Bartholomew Eke (PhD), a Software Engineer and Senior Lecturer at the University of Port Harcourt, Nigeria, Africa. I developed interest on cryptocurrency in 2010 after reading Nakamoto published paper Bitcoin: A Peer-to-Peer electronic cash system (Satoshi,2008) which I saw as a research on cryptography protection of online payments. I didn't well understood it until on Febuary 2014 on hearing that Mt. Gox the largest Bitcoin exchange tend, had gone bankcrupt and had made away with depositors 'Coins'. The word coins attracted my interest, I wondererd why they should be keeping the Coins instead of the notes, but I latter learnt it was not Coins but Bitcoins. Before that time Satoshis's Bitcoin was simply viewed by me as a research exercise aimed at improving crryptography which I had many programs on. The research on tracking of Mt. Gox Bitcoin in the publication of Sarah et. al (2016) increased my interest in Crypto-currency and exchanges research. The research is still ungoing though I have published some of my findings but one of my crushial discovery is that Binance is not just a cryptocurrency exchange but a driver of cryptocurrency and blockchain adoption. I am one of the few people trading in crypto exchanges as part of my research project so it often does not matter whether I gained a trade or lost provided I made my findings. I have used more than 15 exchanges only on experimental bases some of which include Coinbase, Blockchain, Kraken, Bitrrex, Tradesatoshi, Binance, Kucoin, Bit-Z, Cryptopia, Luno, Abucoin and Cryptagio just to mention a few. My criteria of registering include Low volume, High Volume, Low fee, High Fee, difficulty of registration, exchange incentive, exchange policy, cardinal goal of exchange, Fiat or non-fiat, age of exchange and other criteria which I will still publish in my future paper. I have lost and gained crypto in the process of the research but I saw some things that Binance does differently which may or may not have contributed to surge in users interest.
Binance Key Drivers In discussing the story of a young exchange called Binance there are some findings worth mentioning and they include: i) Segregation (Discrimination) : In all the money transfer companies and exchanges I have studied before the advent of Binance there is serious segregation among its customers. In some exchanges this differentiation is very scaring but in Binance it is very minimal, unnoticeable and almost non existent. I will use three experiences to explain, in Coinbase my country (Nigeria) can not trade but they can deposit and withdraw crypto, so why allow them to register only to segregate. Most exchanges, majority of users do not withraw more than 1BTC per day but exchanges group them into three level of users which have different withdrawal limits ( which is very OK for some reasons) but many exchanges go further to place trade restrictions based on this segregations. For instance Cryptopia do not allow you to trade USDT or its equivalent if you are not in certain levels. Bit-z will not allow you to participate in some trading competition or even get airdrops if you are not in some category of user. There are more instances but you will not experience any difference as a user until you want to withdraw above certain limits in Binance. Binance operates little or no discrimination allowing 'Private Crypto' users to remain in level 1 and operate freely provided they withraw smaller amounts. There are many world micro scale and unbanked users who can not afford to get any valid government ID for level 3 registration- Binance is were they fill welcomed. I spent some months as level 1 client and now am in level 2 but my withrawal is hardly upto one BTC a day so I feel no difference but that's not true with many exchanges. ii) Incentives: The unprecidented incentives that Binance offer can make some body with zero dollar to be a marchant with Binance. In November 2017, I told my research students who do not have funds to complete their research work, to register in Binance and generate money to finish their research; they did and are about to graduate. Binance empowered them, they simply registered, got some Airdrops from some new crypto companies, sold and traded with the money and where given trading bonuses and they sold the coins and paid for there research costs via Binance. Their trading incentive vary so much that all kinds of traders benefit, to be more concrete Ontology had a condition of trading 0.5BTC over a week. Using $100 a trader can easily trade five times a day which is $1000 buy-sell volume, in five days that is $5000 volume above 0.5BTC at that time and they gave 1000 ONT which was worth (at some time) $10000, what else is incentive or empowerment. No one can deny these facts. Some new exchanges have copied these model which is great for cryptocurrency adoption. All young school leavers in my area are into Airdrop due to this model introduced by Binance. iii) Low trading Fee : Binance is a cryptocurrency which is accepted for transaction in my local domain thanks to the exchange, for the past six months IT training centers in my locality accept and use Binance as payment for IT training. Trading fee is half when the coin is used to pay for fees but due to its relative stability Binance have found usage in other payments. Beginners can easily learn trading at reduced cost due to low fees. Majority of crypto traders in Binance are startup traders who are learning fast due to trading incentives. iv) High Volume: One of the Support team in Abucoin said that people go to Binance because of there high trading volumes, many people still have the same opinion. But as an academics I know that at a time Binance traded less than 1BTC during their starting stage either as one second or one minute trade volume, they did not start the first second of opening trade with large volumes. BTC only have less than 40% of all Crypto (Coinmarketcap,2018) and Binance introduce good altcoins which was followed by volumes. I was told when Binance started by a forum friend that an exchange that does not offer fiat currency will not attract traders but I differed, insisting that a trader will always prefer to make money in 'Aghanistan and spend it in Paris'. If a trader can ingage in quality trade in an exchange he will only go to the next exchange for cash-out. Cashing out is not always a problem once there is another exchange that is ready to exchange even a single crypto like Bitcoin or even TUSD or USDT. v) Honesty: Binance is an honest exchange, they promise they will distribute prices for trade in a given time you will get it before the time or right at the time they promised. Some exchanges do not add crypto handling delays when they make promise only to discover that a transfer may take 30 seconds today and 3 days the next hour. Binance will tell you two weeks after trading competition the coins will be distributed, they do not usually mean it. What they actually said is that "in two days time after context we will send the winners there coins and the coins can take at most 10 days to reach". In most cases the coins reach in seconds instead of the added days they promised. Cryptocurrency is scary and new users are afraid of dealing with faceless customer service personnels, emails and text messages. What they always want is "your coin is confirming 1/30 confirmations"; they can go to sleep believing that in 5days the coin will be their own. Binance delivers on promises. When they found abnormality that will make customers loss they will raise alarm. For instance during Bytecoin surden price spike in early May 2018 they warned customers to trade with cursion explaining that coin deposit problem may have caused price abnormality-honesty. They constantly remind you to trade with their Binance coin for low fee even when they know that your failure to do that results to higher fees and more gain to the company but they prefer to honestly warn customers. v) Selection of Promising Alt Coins: I am a lecturer in Africa and have never worked with any crypto company but I have traded more than 15 coins in Binance (the evidence is the piece of coin left) but the coins are promising. The coin that is usually at the bottom of the Binance volume is Via Coin which is still a good coin (from my accessment). Most of the coins listed in the exchange easily move up creating great choice and selection space for traders. When crypto exchange grow, users grow and trading space need to grow, Binance is master in that strategy. If a company produces a fake coin or even a 'good coin' with bad road map they will not even approach Binance for listing for two reasons- fear of not spending their money since they do not have plans to make more money from long term plan, fear that there listing request will be rejected. The choice of coins cut across prices and different rating in Coinmarketcap; Binance does not wait for a coin to be in the first 100 before listing them rather if they believe the coin is promising they select the coin. vi) Recognition of developer community Any IT company today that do not take care of its developers or technical teams well will loose them to other cryptocurrency companies and there are many of them coming up. Exchanges seem to believe that there job is to deal on other peoples products but Binance has shown that the best we to understand the crypto world is by been one with it. Binance is not just an exchange, it is a cryptocurrency, a blockchain technology and security and software development organization. This is correct but that can not be said of many exchanges except those copying Binance model. Surprisingly those exchanges copying Binance are also getting visible result. vii) Efficiency and Speed of Site and Trading App. There are things that the Western countries take for granted- power availability and very high speed internet connectivity. Readers of this story from advanced nations should jump to the next point. But the rest of the world have little power which is not even available always and internet cost are high and speed are extremely low. Even when the provider have technology to provide high speed users prefer to have their data last for one full month than to see it finished due to high speed usage. Some times provider intentionally slow down speed to avoid customers outcry of quick finishing data. This calls for exchanges to carry majority of users along in developing there trading platforms. The faster the better and Binance is acting and continues to work on this. viii) Security This is closely related to technology since internally trading apps needed to be upgraded to remain ahead of hackers, crakers and phishing organisations. Early in the year 2018 Binance had a phishing attack, we could easily imagine the state of the cryptocurrency exchange now is they had suceeded. But the phishers could not still coins even when they have broken in, this increased users confidence in the exchange and draw more new clients. The new features added to the exchange have even made email phishing extremely difficult to phishers. There are other security features added which users can sence but are hidden to public discussion. ix) Rich Binance is a rich company, rich in their attitude to the world community, rich in income generation, rich in the way they give to start up companies even when they are also start up themselves, rich in their logo and rich in communicating with customers. Rich in innovative ideas. Binance is rich. Poverty repels, so Binance will keep attracting every body to itself. x) Binance is blessed with an experienced and humble CEO When a company has an experienced leader the multiplier effect is seeing on the rest of the staff. Innovative staff will have little headache in getting their ideas approved. An arrogant leader is a liability to a company and make the company to keep regreting its actions. The leader is planning to go to Malta but he is still insisting that it is just a branch of Binance making the current host the consider its stands on tough regulation.
Binance Road Pot Holes A driver must be careful about pot holes else his good car may tumble. Binance no dought now is really a cryptocurrency innovation adoption driver and must watch out for the following. i) Rise of Communities around cryptos Communities grow a company and communities make companies to go down. If all traders pull out from Binance the company will be history. When Bitcoin started, there was one cryptocurrency community, one group of Bitcoin developers, one Bitcoin enthusiast, but today that is far from the reality. We now have many Bitcoin communities (BTC, BCH, BTCP, BTG etc) and many altcoin communities. Passion have started to roll in these communities and support is continously solicited and soon tougher competitions will ensure the coin to list need to be voted for and a new way for paying for coin listing should be deviced using Binance Coin to vote. ii) Ico Support Binance supports ICOs but for more than three months there LaunchPad on their website have being showing Bread and Gifto, this is very bad. When not launching a coin the LaunchPad need to be empty and when new coin are not coming to the Binance LaunchPad the LaunchPad should go to new coins. Binance community can vote to select the next coin that will go into the LaunchPad. If it required payment then they can use their binance coin to vote and get rewarded by the new coin in a form of shared bounty or airdrop. iii) Strong Community We have discussed the rise of communities, binance is lacking on strong community (a group that have strong passion for Binance as an Exchange, a Cryptocurrency and as a Technology). A community driven by volunteers and not by Binance employee, a community that will work for the passion and not for duty. I see three Binance and the group must be very passionate about the three. This may not be group of Binance Traders - no they are too busy and have no coin or exchange friend. Binance may be working towards this direction in the Binance Angels project but wisdom must be used to get the correct arrow head of the community and to actually let go of the person to freely handle the community. If the staff want to lord it on the community followership will be for duty not for the passion. iv) Binance Bounties Binance have so many trading bounties won after the competitions. This is good but part of this bounties need to be used to bring in more new users who will register and a buy Binance and smaller amount for new members without any conditions. The trade competitions the way most of them are ends up in the hands of already suceessful members who can trade once a day and win the competition due to there financial musle. These group of big traders are highly desirable and will continue to remain in the first to third places. But future members need to be attracted with the little tokens falling out from every bounty. v) Need for Binance_Inc Exchange Binance is so big and will get bigger. Binance need to have another cryptocurrency exchange, but instead of just an exchange Binance should have an incubator exchange. 'Division Two exchange' this exchange will be low volume and should serve as a source for listing in the main exchange. If a coin is performing with high volume it can be moved to the main exchange. In a crypto in the main exchange is not performing in they can be moved back to the incubator exchange. In this way Binance will remain the technology and develop in other areas.
Binance as an Innovative Crypto-currency Adoption Driver It has been said that adoption is the original dependent variable in innovation research and the desirable property of innovative systems which change agents seek to enhance. "Innovation" on the other hand is any change in structure, design, products, or processes in which there is a definable new element introduced into the system; the process is essentially the same for all technologies including blockchain technologies. In innovative space the characteristics of people or organizations are associated with higher levels of adoption and the company that makes the adoption to happen faster is very innovative. The voiced or unvoiced assumption underlying the examination of correlates of innovativeness is causal: If we manipulate the characteristics of organizations or individuals so that they more closely resemble those of the highly innovative, we will make the organizations or individuals themselves more innovative (Eveland, 1979)
Conclusion It is very easy to conclude this article by saying that since Binance was able to make more people to adopt cryptocurrency in a fast manner that they are not only drivers of cryptocurrency adoption but they are Innovative. Ask of an innovative cryptocurrency exchange the response should be Binance, when they move others copy so without the statistics of their trade volumes one can easily see that they are truely the leaders that the crypto exchange space have today.
