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.
Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with ablockchainnetwork structure, a notion first created byStuart Haber and W. Scott Stornetta in 1991.
Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.
Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).
In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW). The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer. Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs. As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”). Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so. With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic. Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.
The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979. With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”). An illustration of block production in the Bitcoin Protocol is demonstrated below. https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d
Block time and mining difficulty
Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty. Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly. Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.
What are orphan blocks?
In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency. It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency. Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted. The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network. However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.
3. Bitcoin’s additional features
Segregated Witness (SegWit)
Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017. SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin. SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become. https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit. Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade. Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values. For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890. Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid. This can create many issues, as illustrated in the below example:
Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID. Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.
Lightning Network is a second-layer micropayment solution for scalability. Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins. Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ. A list of curated resources relevant to Lightning Network can be found here. In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions. Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel. https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8 One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel. However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.
Schnorr Signature upgrade proposal
Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain. https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4 However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys. This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block. https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually. Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.
4. Economics and supply distribution
The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years. As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.
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)
What is on-chain cryptocurrency governance? Is it plutocratic? by Richard Red (medium)
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?

About This Issue
This is the third issue of Decred Journal after April and May. Most information from third parties is relayed directly from source after a minimal sanity check. The authors of Decred Journal have no ability to verify all claims. Please beware of scams and do your own research. The new public Matrix logs look promising and we hope to transition from Slack links to Matrix links. In the meantime, the way to read Slack links is explained in the previous issue. As usual, any feedback is appreciated: please comment on Reddit, GitHub or #writers_room. Contributions are welcome too, anything from initial collection to final review to translations. Credits (Slack names, alphabetical order): bee and Richard-Red. Special thanks to @Haon for bringing May 2018 issue to medium.
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.

[Daily BAT Discussion] In Plain Sight - January 10, 2018
January 10, 2018 Hey BAT bunnies! Welcome to the Daily BAT Discussion! Yesterday's Market Movements - Sort of Sideways Consolidation Yesterday we saw another insane run-up in the middle of the day, hitting an ATH on Bittrex at 6777 sats ($0.96) while Binance retouched it for the 2nd time in two days. Afterwards, the BAT rocket cooled off when Ethereum began to take off. At the time of this post, we ended around where we started the day, around 5500 sats ($0.78). It's actually hard to fathom that I'm saying BAT had to fall back down to 80 cents haha. Even though we saw an insane run-up in price as well as a relatively quick descent, the community growth shows ever-increasing awareness and support. We got another 300 subs for the 3rd day in a row! Also, the BAT token holders have been growing at a rate of 500 new addresses per day! This is absolutely huge growth compared to seeing less than 100 in a single day a few months ago! (Recap) Binance Opens up Registration If you are still looking to get your hands on some BAT through Binance (referral link), they have just reopened registration! If you've never bought from an exchange or would like some help, check out the tutorial below to walk you through purchasing some BAT! (Recap) Uphold adds Debit/Credit Card Purchasing If you are looking to get some BAT fast, Uphold has just added debit/credit card purchasing. Uphold is an easy way to acquire BAT straight from fiat. If you didn't know, Uphold is one of Brave's official partners! Register here. Caution: Someone in the community discovered that Uphold does not work for New York citizens (Recap) Getting the Daily Stickied CryptoJennie has responded about getting the Dailies sticked. Currently they are working on settling some issues with the unofficial Facebook group, and once that is finished, these dailies should be getting some love and pinned to the top. Tutorials Here are some guides for new people getting into crypto, especially BAT. Invest responsibly!

4 Sub-$10 Million Market Cap Coins Worth Keeping An Eye On
1. Spectrecoin ($XSPEC) – $8.6 Million
What is Spectrecoin?
Utilizing a “range of proven cryptographic techniques” to achieve anonymous, untraceable, and un-linkable transactions, Spectrecoin is a secure Proof-of-Stake cryptocurrency enabling rapid P2P transactions and network privacy. Specifically, Spectrecoin is pulling out all the stops in order to protect user identity through their integration of:
Built-in Tor: Derived from the original software project moniker—The Onion Router—Spectrecoin is fully integrated with Tor, protecting real IP addresses at all times through the directing of traffic through a worldwide (and free) overlay network of more than 7,000 relays.
Anonymous coin creation: Deploying dual key stealth technology (a dual coin system), Spectre authorizes users to generate ‘anonymous coins’ known as SPECTRE for private and anonymous transactions as an alternative to their normal, everyday coin—XSPEC—for traditional transactions (most similar to Bitcoin).
Ring signatures: Through the execution and implementation of ring signatures, Spectrecoin user transaction history is wiped altogether, allowing users to exchange and transfer public coins, XSPEC, and SPECTRE.
At its core, Spectre’s dual coin system sanctions four fundamental types of privacy and anonymity transactions, XSPEC > XSPEC, XSPEC > SPECTRE, SPECTRE > SPECTRE, and SPECTRE > XSPEC, providing a plethora of transaction options for every type of user. And finally, if you’re looking for the TLDR (too long, didn’t read), Spectrecoin notes the best way to understand SPECTRE is to think of Bitcoin + Proof-of-Stake.v3 + anonymous transactions (similar to Monero) + Tor (for IP obfuscation).
Why You Should Keep an Eye On XSPEC
Unlike several other privacy coins which merely provide a Tor proxy—availing users to potential malicious exit nodes—Spectrecoin is fully integrated with Tor, a reliable and tested network providing one of the largest pools of IP addresses for confidentiality and untraceability. Coupled with staking, set at a 5% minimum per year, Spectrecoin offers a unique proposition (the only one in blockchain) for users looking to earn rewards while remaining anonymous by staking anonymous coins while generating more, fresh anonymous ones. Furthermore, for those looking for affirmation of Spectrecoin’s commitment to anonymity, not even the developers know each other’s real names—something that would have made walking away from a lacklustre ICO (which only raised 16 BTC at $600/700 per BTC) all too easy. Spectre has emphasized organic growth without an excessive and aggressive marketing push, opting instead for a working product and timely improvements to meet the ever-changing privacy arms race. And, with their funding gap set around £19,000, users can take solace in knowing the project isn’t an outright cash grab asking for millions to further tenuous goodwill—like far too many projects in the cryptosphere. At time of writing, XSPEC is listed on CoinMarketcap at US$0.41 or 5,970 Satoshis. Finally, if you’re wondering how Spectrecoin stacks up to other privacy coins, such as Monero, PIVX, and Zcash, check out this comparison chart.
2. FundRequest ($FND) – $1 Million
What is FundRequest?
In an age where open source software is an integral component for institutional, government, and nonprofit function and growth, there unfortunately remains a hindering factor—a cohesive, transparent, and styled request and transaction flow. Cue FundRequest, a decentralized marketplace for open source collaboration and catalyst for global open source sharing and circulation, empowering organizations, government, and other entities to:
Trustlessly transact via the blockchain and smart contracts to ensure all contracts created are self-resolving, tracked, and validated in a fair manner,
Incentivize organizations and developers to act in good faith through governance protocols and crypto economics,
Lower costsfor upkeep, while reducing friction for large-scale usage and adoption of open source technology,
Boost transparency for organizations looking to better understand average development and issue costs (ultimately resulting in a more efficient market), and
Integrate with third-party platforms (and vice versa), who are looking to benefit from already completed works.
Need to brush up on what exactly ‘open source’ means? The Open Source Initiative describes the concept of ‘open source’ as a tool which “enables a development method for software that harnesses the power of distributed peer review and transparency of process.” For example, a requesting organization (referred to as the funder) will allot set funds—stored in a smart contract (i.e., escrow)—in order to tackle an open source issue, which is then picked up and solved by a developer (the solver). In order to eliminate malicious behavior, FundRequest requires solvers to “have skin in the game,” by staking proportional valued funds, all released and claimed once the issue is solved. Simply put, FundRequest is the go-to facilitating and incentivization platform (similar to Airbnb and Uber) for funding, claiming, and rewarding open source commits and contributions, leading to an enriched and more collaborative open source ecosystem.
Why You Should Keep an Eye On FND
With an estimated US$60 billion-plus in savings per year for organizations and institutions, thanks to open-source software and technology adoption, FundRequest is set to act as the glue which connects all dispersed and integral parts and actors. Traditional software, prohibitive costs, and predatory vendor practices are proving not to be conducive towards maximal technological growth and development, as most people and organizations just simply can’t afford or maintain it. Plus, with a clear push by both private and public sectors to leverage community-based software for development and distribution over the last decade, it’s expanding at rapid pace. In 2018, it’s approximated over 50% of European and North American companies utilize open source software for “crucial applications,” along with over 50% of American government organizations. This is no small industry. GitHub alone boasts over 24 million users (more than 8 times their user base five years ago), and it’s estimated that in the EU and United States combined, there’s over 160 million persons working as freelancers and independent contractors in what’s known as the “gig economy.” And that’s just the tip of the iceberg, with over 60% of online gig economy workers accounted for in Asia. As of August 1st, FND’s price sits at right around US$0.03 or 472 Satoshis. Finally, for open source projects and ERC-20 token projects looking to increase development capacity, consider checking out FundRequest for potential partnerships. Already in their short tenure, FundRequest has partnered with:
Redefining convenience, simplicity, and compatibility, and short for the “Crypto One-Stop Solution’ exchange and platform, COSS is the native token and liquidity attraction tool of the Singapore-based exchange, boasting some of the most popular altcoins on the market while enabling users to receive weekly payouts in “dust” for all traded tokens. Specifically, COSS is looking to provide more than just a simple, fast, and secure cryptocurrency trading exchange—they’re building a borderless, digital economical system to bring cryptocurrencies to the masses via:
Digital wallet with integrated cash flow: allowing users to seamlessly transfer and store crypto funds between the exchange and wallet within a single application.
ICO platform: enabling projects to fund and their ICO on the COSS exchange to increase popularity, volume, and trading value.
Ultimately, COSS is looking to shake up the cryptocurrency exchange ecosystem through improved user experience, heightened product and feature functions, and a comprehensive foundation for employers, startups, companies, and traders to build towards a more accessible and mainstream cooperative blockchain community.
Why You Should Keep an Eye on COSS
With the rapid and gargantuan successes enjoyed by both Kucoin and Binance in 2018, crypto exchanges employing user-friendly token incentivization models are becoming a go-to for users looking to generate passive income while diversifying their crypto portfolio. However, unlike other cryptocurrency exchanges which have lowered their daily fee splits to nominal amounts, COSS has stayed true towards user rewards, keeping their daily percentage at 50%—paying out the respective dividends via a decentralized autonomous organization, ultimately guaranteeing an immutable percentage. In order to stay competitive in the present-day blockchain ecosystem, COSS’s whitepaper notes a minimum of 3-5 new features implemented per quarter. In the past several months, below are just several of their most notable achievements:
Partnership with Blockchain Terminal (BCT): Easing the transition for institutional investors to trade and transact on crypto exchanges.
NEO Listing: Trading pairs for NEO/BTC, NEO/ETH, NEO/USD, and NEO/COSS.
Preparation for COSS 2.0: The hiring of a team of over thirty developers in preparation of COSS 2.0, which is set to roll out dynamic withdrawal fees, sophisticated trading tools, dust conversion, public and private APIs, new wallet, institutional accounts, and more.
And, if you’re looking to know what COSS’s endgame here is, their goal is to shift completely towards a decentralized autonomous organization (DAO) in the future, where governance and decision making is outlined in code and run by a peer-to-peer network. Currently, COSS’s price is listed at US$0.06 or 935 Satoshis on Coinmarketcap. Finally, if you’re curious about COSS’s fee sharing, check out the COSS fee share calculator, which provides an accurate picture of your monthly exchange fee earnings relative to the amount of COSS owned. One Reddit user recently posted, and provided a screenshot, showing the COSS annual dividends to be at nearly 10% per year.
4. Lamden ($TAU) – $6.9 Million
What is Lamden?
Named after the Sherpa language word meaning “to guide,” Lamden is staying true to its name by easing the creation and deployment of dapps and custom blockchains. At its core, Lamden is providing a suite of developer tools mimicking “modern development processes in such tech stacks as Node.js or Python.” Simply put, Lamden is supplying the building blocks for experienced and amateur blockchain developers alike, enabling organizations and enterprise to skirt the energy and time costs of hiring and training expensive blockchain developers—ultimately speeding up efficiency and reducing overhead costs. Lamden is broken up into three fundamental sections, which all are in furtherance of project depth and the deployment of hyperfast blockchains for developers to not only experiment with, but test and deploy across other blockchain systems and platforms:
Saffron: a general tool sanctioning the deployment of private chains on an internal network, partitioning blockchains into individual use cases (e.g., an enterprise having their own web app), and bringing them together to interact when needed. Lamden CEO Stuart Farmer noted that from blockchain generation, to installment, all the way to deployment, an entire deployment cycle can be completed within a frame of just ten minutes!
Flora: a central repository for smart contract templates and packages, blockchain discovery tool, and private chain naming services, where developers are able to engage with one another, feed off one another’s innovations, and rapidly deploy and distribute smart contracts.
Clove: a payment network trustlessly facilitating communication between blockchain apps while handling payment channel swap processes, avoiding blockchain bloat and acting similarly to a telephone network.
Furthermore, Lamden supports the Ethereum network and Bitcoin-based blockchains at present, and boasts zero transaction fees and free chain-to-chain payments in exchange for chain allocation a specific amount of bandwidth for confirming payment channel transactions—meaning that its users are able to transact for free as a result of corporate entities bearing the network load and processing.
Why You Should Keep an Eye On TAU
Having released their ‘Cilantro’ testnet alpha in February 2018, Lamden has since hit the ground running, rolling out their first version of Clove soon after and tackling the necessary tune-ups and improvements in preparation of their mainnet launch in Q4 2018. Lamden’s mainnet is set to utilize a unique combination of Delegated Proof-of-Stake (DPoS) and the BFT Protocol, and will scale to process nearly 10,000 transactions per second. Moreover, in April 2018, Lamden announced the creation of LamDEX, their own decentralized cryptocurrency exchange and platform, where users will be able to stake their TAU—the native token of the Lamden platform—to act as a market maker, allowing for a cohesive back and forth across the TAU pair at prices faintly above and below market cost, ultimately generating rewards. With a rather daunting and tedious task ahead for anyone looking to utilize and incorporate existing smart contracts—which involves the manual searching for such on GitHub (a general repository website)—Lamden is truly adding value to blockchain and application development through their smart contract repository. Unlike GitHub, Lamden supports dependencies, versioning, and security, all essential elements for a quality package manager. Doing so adds not only convenience, but practicality to smart contract packages and implementation, and stands to save enterprise and organizations both exorbitant developer costs and time. If you’d like to learn more about Lamden’s developer tool suite, check out this complete overview from their blog. At the time of writing, Lamden’s price according to Coinmarketcap is US$0.04 or 699 Satoshis.

Final Thoughts Risk is inevitable when investing in crypto and blockchain projects. However, as long as you are cognizantly defining parameters for absorbing such risk, then diversifying your portfolio with smaller capped projects can be an effective way to realize value. Whether you’re looking for a user-friendly exchange to purchase crypto directly with fiat from (and earn dividends for loyalty) or wanting to execute anonymous and secure transactions with a P2P coin, the aforementioned projects are all bringing value to the crypto sphere through their overhaul of ineffective traditional mechanisms and institutions. Make sure to stay calm and collected during this bear market, associate yourself with quality projects that you think are bringing actual value to severely flawed industries, and remember, having a little gamble in you never hurts (as long as it’s properly accounted for).
