Last year Bitfury’s multidisciplinary Blockchain specialists announced the possibility of revealing the identities of more than 16% of all owners of Bitcoin addresses. Several years ago, a team of CryptoLux developers, having conducted a study of transaction privacy on the Bitcoin network, concluded that 60% of all addresses can be deanonymized. Summarizing all this, it’s worth highlighting three existing methods that can successfully deanonymize private transactions.
The easiest way to cluster (link Bitcoin addresses) is by analyzing transactional networks. In other words, this is a method that allows finding several inputs combined in one transaction. The second clustering method is “distribution analysis”. It allows calculation the percentage of cryptocurrency at the certain address that comes from another specific address and it becomes clear whether these addresses are connected by one direct transaction or a chain of transactions or not.
It consists of quantitative and temporal analyzes. Quantitative analysis studies not certain transactions, but amounts. Time analysis tracks specific periods.
Memory Pool Method
When a transaction is made through the user’s wallet, the input nodes send information about the transaction to the Blockchain network. The purpose of this method is to identify the set of input nodes through the wallet and the user. In this case, the IP address of the client can be associated with its transactions. There are certain private cryptocurrency-leaders which are popular and trusted among users. Using one feature-privacy, they have different ways of functioning.
Basic principles of work: anonymous cryptocurrencies (Monero, Dash, Zcash)
The platform focuses on privacy and decentralization. The coin uses three levels of protection: • Ring signatures, that hide the origin of the sender by mixing the user’s address with the addresses of other group members. • Ring confidential transactions, which hide the amount of the transaction. • Stealth addresses, that allow a user to hide the recipient’s address. Such way guarantees the privacy of the sender and the recipient. Monero can be bought on Poloniex, Bitfinex, Livecoin, and Kraken crypto exchanges. It is possible to store Monero via an online wallet. More secure is its computer wallet. Due to its privacy, the popularity of the coin is expected to grow, so it makes sense to add a coin to an investment portfolio. Advantages • Increased privacy. Cryptocurrency is suitable for those who are afraid of deanonymizing network transactions. • Unlimited and difficult mining. • It takes less time to find blocks. • Resistance to the centralization of mining capacities. Disadvantages • Resources. All currency protection technologies require impressive machine performance for normal operation. The Monero block size is constantly growing, and this requires additional resources of network participants. • The popularity in the dark web leads to problems in working with regulatory authorities, exchanges often delist it. Speaking of reputation, Monero’s reputation is far from the best. The coin is often used on the dark web as payment for various illegal services. It happens to almost all crypto coins that provide privacy. • Large transaction sizes. Since Monero Blockchain is five times larger than the Bitcoin Blockchain in terms of one transaction. • Problems with scalability.
The Dash platform is a classic decentralized Blockchain-based payment system and the most technologically advanced cryptocurrency. It implements multi-off-chain money transfers without loss of reliability and overall security of the Blockchain. Its confidentiality is rather an additional option that can be used optionally. In the case of anonymity, it is possible to send a hidden transaction, but at a more expensive cost, which also requires additional time. Dash developed a hashing algorithm with eleven cryptographic functions-X 11 for the first time. The coin developers have released apps for other platforms. Today it is possible to use Dash for IOS, Zeal for Linux, LovelyDocs for Android and Velocity for Windows. As well known, the CoinJoin is an anonymization method for crypto transactions, which is used by Dash as an improved version called the PrivateSend. Its mixing sessions are limited to 1,000 DASH for each session and will require multiple mixing sessions to anonymize a large amount of money. Advantages • High transaction speed. It is achieved via InstantX technology, which enables the confirmation of operations in less than 4 seconds. • Law transaction fees. • Energy consumption. Unlike Monero, it does not require a lot of power or high commission costs. Disadvantages • “Transparency” of the network. Without triggering the “mixing” mechanism, the directions of transactions and their balances are publicly visible to everyone. • Lack of proper cryptographic technologies that provide privacy, but can provide a sufficiently high level of protection. • Transaction visibility to the founders and the team.
An open-source decentralized cryptocurrency that provides users with maximum privacy. Zcash is the first private cryptocurrency, using cryptographic protocol zk-SNARKS, a zero-knowledge security layer. It allows users to make hidden and open transactions. Mathematically guaranteed privacy is something cryptocurrency can not be proud of. This fact makes the currency specific. All Zcash coins are identical, it means that interchangeable coins do not contain information about past use created. In this regard, the connection of coins with their history on the Blockchain is broken, which makes them universal and identical to each other. Zcash blocks are generated 4 times faster than Bitcoin. The currency trades on Huobi, Bitfinex and Binance exchanges, and after purchase, it can be stored on the exchange’s internal wallet, as well as transferred to Jaxx, Cryptonator and Coinomi multi-currency wallets. Coins can also be stored on hardware wallets like Ledger and Trezor. Advantages • Privacy. Since no information except the time stamp, is recorded in the Blockchain, transactions cannot be tracked, and the identity of the sender and recipient is almost impossible to establish. • Interchangeability. Due to interchangeability, all coins have a “clean” history. This means that it is practically impossible to determine which transactions coin was used. • Security. Lack of information about user keys, which protects user wallets and the network.Mining energy efficiency. Zcash mining hardware consumes less electricity than Bitcoin mining ASICs. • The difficulty of mining. Zcash is beneficial for those who want to get coins for block creation. Bitcoin mining becomes more and more complicated, so miners cannot earn enough money via their computers with high capacity. Disadvantages • 6 users can decide to leave the transferred data completely open. • It takes a lot of calculations to complete a transaction. • Insecurity. There are fears that the system could be hacked, or users may accidentally open the data. • Legally ZCash is supported only by Linux, however, it provides users with wallets for other platforms: Jaxx, Ledger, Trezor, Trust, Zecwallet, Ibitcome, Exodus, Guarda, Coinomi, Cobowallet, and Bitgo. Private cryptocurrencies are necessary for anyone who values the privacy and confidentiality of financial transactions. Privacy can generate more value, than danger, as Eric Hughes says: “Privacy is necessary for an open society in the electronic age. Privacy is not secrecy. A private matter is something one doesn’t want the whole world to know, but a secret matter is something one doesn’t want anybody to know. Privacy is the power to selectively reveal oneself to the world”.

The IEO was oversold by over 25X! Here are the questions and answers we have recorded to share with you. 1) Can you briefly explain TokenTuber to us? TokenTuber is a curated video content platform combined with a token economy that initially targets blockchain novices and crypto traders globally. TokenTuber combines concepts from platforms like YouTube and Steemit with lessons from building cryptocurrencies and their communities. All contributors of the TokenTuber platform can expect to be rewarded fairly for their contributions. 2) Why did you guys start TokenTuber? We are trying to lower the barriers to entry for novices and create mass adoption for blockchain and cryptocurrency, hoping one day that everyone who has heard about blockchain or bitcoin will have and use cryptocurrency. 3) How does TokenTuber work? Anyone can upload a blockchain/crypto related video by submitting a Youtube URL on TokenTuber, and anyone can invite the video producers to claim their videos. Each video will have certain value (TUBER) associated with it depending on how many upvotes the video gets, each user can upvote 5 videos a day for the videos they like. The more viral the video is, the more TUBER the video producer will get, and so will those users who upvoted that video. TokenTuber will collaborate with YouTube instead of competing, and will redirect all these video links back to YouTube. TokenTuber’s token is called TUBER, and will be used to pay out all the platform’s rewards. 4) What can users gain from TokenTuber? TokenTuber will reward all platform contributors, whether its content creation, content discovery (upvote + investment game to top videos), or content curation (report of inappropriate videos). Also, users will have access to curated content specifically designed to educate users on all topics in the blockchain and cryptocurrency space. 5) What’s TUBER’s tokenomics and what is the utility of TUBER? Besides the behavior mining mentioned above that rewards all contributors, we designed a feature called “The Investment Game” where users will need to use TUBER. Users can invest in videos using TUBER to pin the video they like in the TOP category for 24 hours, thus increasing video’s exposure. Users who invest will have a chance to earn TUBER if there are follow-up investors in the same video. This innovative feature is first of its kind and will be released before end of this year. 6) Does TokenTuber have any partnerships that you would like to share? We currently have 3 strategic partnerships and have announced two of them. One with SoPay, a crypto payments service platform and one with Quarkchain, a blockchain based on sharding technology. You can read about these partnerships and our other announcements here: https://www.tokentuber.com/announcement/ I will also explain a bit later how we partner with exchanges to form an exchange alliance. Stay tuned as we announce further partnerships! 7) Can you share more about your marketing plans going forward? Our first big campaign will be the Crypto Beginner Quiz, similar to the concept of a driver’s license test. Those who fail the quiz are discouraged from holding crypto assets and we encourage them to learn more on TokenTuber first. We want to challenge users to see if they have what it takes to be an ‘Accredited Crypto Holder’. To make this quiz viral, we have set a 10K USD prize pool for the top 100 people who share the quiz. You can learn more here: https://www.tokentuber.com/quiz. What’s exciting is that we started this exchange alliance concept so the questionnaires can be designed with the top exchanges together. We hope that the traders will have the necessary knowledge before they begin trading. We will be partnering with major Crypto Youtube KOLs as well, also big media is coming. Stay tuned. 8) Can you tell us more about TokenTuber’s roadmap? You can see the image below of our upcoming roadmap and major milestones. https://preview.redd.it/wmlw9dlujop31.png?width=864&format=png&auto=webp&s=278431872ecf20801189b069d07c456a956ec506 9) Have you planned to hold a meeting in Russia recently? Currently we are busy working with online KOL’s and haven’t yet done anything offline yet, but we do welcome anyone who has offline resources to join our global ambassador partnership program. 10) How many users do you currently have? Did the community know you a lot? We currently just started the marketing effort this month because our beta product was launched earlier this month, but we believe the user base will ramp up quite quickly due to our first viral marketing campaign of crypto beginner quiz. 11) As I know Contentos is also a content reward platform and listed on Binance already. So, do you think they will be a big competitor of TokenTuber? How is your project out standing compared to it or other projects which has same functions like this? It appears to me that Contentos is competing with Steemit, not us, because our mission and vision are different. We are purely focused on delivering blockchain and crypto content to lower the barriers to entry for novices, see my AMA response for Question 2 regarding mission and vision and why we started TokenTuber. 12) What are the biggest challenges you expect to face and how do you plan to overcome these challenges? Biggest challenge is fake accounts and bots that come and claim our giveaways/tokens, and we are designing over 10 ways to block them. 13) Your tagline is “TokenTuber — Your gateway to the crypto world.” Will this prevent you from focusing solely on Crypto — a market with too few people interested in stocks or forex? Currently, the crypto market has very limited users, around 50 million crypto holders globally, what we are trying to accomplish is to tap into the mass market of 5 billion+ potential crypto holders whom have already heard about the blockchain/bitcoin buzz word, yet they are finding themselves with high barriers to entry or many doubts. So the educational component is a must to help these potential users to join into the crypto world, and we hope to be the first portal to help them accomplish this step. 14) With YouTube being so popular nowadays, can you develop it according to your own roadmap or merge? Yes, Youtube is currently the most popular video education portal for the crypto world, but it’s not optimized for the crypto audience. Let’s say you search for EOS, and you will get results of a Canon eos camera. I think TokenTuber and Youtube can co-exist but we will have more curated videos with a better tag system for the crypto world, where Youtube will be a complete database of all videos, so users shall find our platform to be more efficient and effective to learn about crypto 15) Why did you choose Hotbit for IEO? We chose Hotbit for a reason, I am also an investor myself, when I put on my investment hat and spoke with different exchange’s founders and management teams, I found that Hotbit is the next potential dark horse. They are very low profile yet their trading volume stats are already in top 20 on Coingecko after removing all the wash trading volumes. Also many of my friends in the crypto space recommended Hotbit and I personally met with the CEO of Hotbit and we enjoyed our chats. There are multiple reasons and we ended up picking Hotbit as our first exchange to partner with out of 5 exchanges that I am personally well connected with.

Crypto and the Latency Arms Race: Crypto Exchanges and the HFT Crowd
News by Coindesk: Max Boonen Carrying on from an earlier post about the evolution of high frequency trading (HFT), how it can harm markets and how crypto exchanges are responding, here we focus on the potential longer-term impact on the crypto ecosystem. First, though, we need to focus on the state of HFT in a broader context.
Conventional markets are adopting anti-latency arbitrage mechanisms
In conventional markets, latency arbitrage has increased toxicity on lit venues and pushed trading volumes over-the-counter or into dark pools. In Europe, dark liquidity has increased in spite of efforts by regulators to clamp down on it. In some markets, regulation has actually contributed to this. Per the SEC:
“Using the Nasdaq market as a proxy, [Regulation] NMS did not seem to succeed in its mission to increase the display of limit orders in the marketplace. We have seen an increase in dark liquidity, smaller trade sizes, similar trading volumes, and a larger number of “small” venues.”
Why is non-lit execution remaining or becoming more successful in spite of its lower transparency? In its 2014 paper, BlackRock came out in favour of dark pools in the context of best execution requirements. It also lamented message congestion and cautioned against increasing tick sizes, features that advantage latency arbitrageurs. (This echoes the comment to CoinDesk of David Weisberger, CEO of Coinroutes, who explained that the tick sizes typical of the crypto market are small and therefore do not put slower traders at much of a disadvantage.) Major venues now recognize that the speed race threatens their business model in some markets, as it pushes those “slow” market makers with risk-absorbing capacity to provide liquidity to the likes of BlackRock off-exchange. Eurex has responded by implementing anti-latency arbitrage (ALA) mechanisms in options: “Right now, a lot of liquidity providers need to invest more into technology in order to protect themselves against other, very fast liquidity providers, than they can invest in their pricing for the end client. The end result of this is a certain imbalance, where we have a few very sophisticated liquidity providers that are very active in the order book and then a lot of liquidity providers that have the ability to provide prices to end clients, but are tending to do so more away from the order book”, commented Jonas Ullmann, Eurex’s head of market functionality. Such views are increasingly supported by academic research. XTX identifies two categories of ALA mechanisms: policy-based and technology-based. Policy-based ALA refers to a venue simply deciding that latency arbitrageurs are not allowed to trade on it. Alternative venues to exchanges (going under various acronyms such as ECN, ATS or MTF) can allow traders to either take or make, but not engage in both activities. Others can purposefully select — and advertise — their mix of market participants, or allow users to trade in separate “rooms” where undesired firms are excluded. The rise of “alternative microstructures” is mostly evidenced in crypto by the surge in electronic OTC trading, where traders can receive better prices than on exchange. Technology-based ALA encompasses delays, random or deterministic, added to an exchange’s matching engine to reduce the viability of latency arbitrage strategies. The classic example is a speed bump where new orders are delayed by a few milliseconds, but the cancellation of existing orders is not. This lets market makers place fresh quotes at the new prevailing market price without being run over by latency arbitrageurs. As a practical example, the London Metal Exchange recently announced an eight-millisecond speed bump on some contracts that are prime candidates for latency arbitrageurs due to their similarity to products trading on the much bigger CME in Chicago. Why 8 milliseconds? First, microwave transmission between Chicago and the US East Coast is 3 milliseconds faster than fibre optic lines. From there, the $250,000 a month Hibernia Express transatlantic cable helps you get to London another 4 milliseconds faster than cheaper alternatives. Add a millisecond for internal latencies such as not using FPGAs and 8 milliseconds is the difference for a liquidity provider between investing tens of millions in speed technology or being priced out of the market by latency arbitrage. With this in mind, let’s consider what the future holds for crypto.
Crypto exchanges must not forget their retail roots
We learn from conventional markets that liquidity benefits from a diverse base of market makers with risk-absorption capacity. Some have claimed that the spread compression witnessed in the bitcoin market since 2017 is due to electronification. Instead, I posit that it is greater risk-absorbing capacity and capital allocation that has improved the liquidity of the bitcoin market, not an increase in speed, as in fact being a fast exchange with colocation such as Gemini has not supported higher volumes. Old-timers will remember Coinsetter, a company that, per the Bitcoin Wiki , “was created in 2012, and operates a bitcoin exchange and ECN. Coinsetter’s CSX trading technology enables millisecond trade execution times and offers one of the fastest API data streams in the industry.” The Wiki page should use the past tense as Coinsetter failed to gain traction, was acquired in 2016 and subsequently closed. Exchanges that invest in scalability and user experience will thrive (BitMEX comes to mind). Crypto exchanges that favour the fastest traders (by reducing jitter, etc.) will find that winner-takes-all latency strategies do not improve liquidity. Furthermore, they risk antagonising the majority of their users, who are naturally suspicious of platforms that sell preferential treatment. It is baffling that the head of Russia for Huobi vaunted to CoinDesk that: “The option [of co-location] allows [selected clients] to make trades 70 to 100 times faster than other users”. The article notes that Huobi doesn’t charge — but of course, not everyone can sign up. Contrast this with one of the most successful exchanges today: Binance. It actively discourages some HFT strategies by tracking metrics such as order-to-trade ratios and temporarily blocking users that breach certain limits. Market experts know that Binance remains extremely relevant to price discovery, irrespective of its focus on a less professional user base. Other exchanges, take heed. Coinbase closed its entire Chicago office where 30 engineers had worked on a faster matching engine, an exercise that is rumoured to have cost $50mm. After much internal debate, I bet that the company finally realised that it wouldn’t recoup its investment and that its value derived from having onboarded 20 million users, not from upgrading systems that are already fast and reliable by the standards of crypto. It is also unsurprising that Kraken’s Steve Hunt, a veteran of low-latency torchbearer Jump Trading, commented to CoinDesk that: “We want all customers regardless of size or scale to have equal access to our marketplace”. Experience speaks. In a recent article on CoinDesk , Matt Trudeau of ErisX points to the lower reliability of cloud-based services compared to dedicated, co-located and cross-connected gateways. That much is true. Web-based technology puts the emphasis on serving the greatest number of users concurrently, not on serving a subset of users deterministically and at the lowest latency possible. That is the point. Crypto might be the only asset class that is accessible directly to end users with a low number of intermediaries, precisely because of the crypto ethos and how the industry evolved. It is cheaper to buy $500 of bitcoin than it is to buy $500 of Microsoft shares. Trudeau further remarks that official, paid-for co-location is better than what he pejoratively calls “unsanctioned colocation,” the fact that crypto traders can place their servers in the same cloud providers as the exchanges. The fairness argument is dubious: anyone with $50 can set up an Amazon AWS account and run next to the major crypto exchanges, whereas cheap co-location starts at $1,000 a month in the real world. No wonder “speed technology revenues” are estimated at $1 billion for the major U.S. equity exchanges. For a crypto exchange, to reside in a financial, non-cloud data centre with state-of-the-art network latencies might ironically impair the likelihood of success. The risk is that such an exchange becomes dominated on the taker side by the handful of players that already own or pay for the fastest communication routes between major financial data centres such as Equinix and the CME in Chicago, where bitcoin futures are traded. This might reduce liquidity on the exchange because a significant proportion of the crypto market’s risk-absorption capacity is coming from crypto-centric funds that do not have the scale to operate low-latency strategies, but might make up the bulk of the liquidity on, say, Binance. Such mom-and-pop liquidity providers might therefore shun an exchange that caters to larger players as a priority.
Exchanges risk losing market share to OTC liquidity providers
While voice trading in crypto has run its course, a major contribution to the market’s increase in liquidity circa 2017–2018 was the risk appetite of the original OTC voice desks such as Cumberland Mining and Circle. Automation really shines in bringing together risk-absorbing capacity tailored to each client (which is impossible on anonymous exchanges) with seamless electronic execution. In contrast, latency-sensitive venues can see liquidity evaporate in periods of stress, as happened to a well-known and otherwise successful exchange on 26 June which saw its bitcoin order book become $1,000 wide for an extended period of time as liquidity providers turned their systems off. The problem is compounded by the general unavailability of credit on cash exchanges, an issue that the OTC market’s settlement model avoids. As the crypto market matures, the business model of today’s major cash exchanges will come under pressure. In the past decade, the FX market has shown that retail traders benefit from better liquidity when they trade through different channels than institutional speculators. Systematic internalizers demonstrate the same in equities. This fact of life will apply to crypto. Exchanges have to pick a side: either cater to retail (or retail-driven intermediaries) or court HFTs. Now that an aggregator like Tagomi runs transaction cost analysis for their clients, it will become plainly obvious to investors with medium-term and long-term horizons (i.e. anyone not looking at the next 2 seconds) that their price impact on exchange is worse than against electronic OTC liquidity providers. Today, exchange fee structures are awkward because they must charge small users a lot to make up for crypto’s exceptionally high compliance and onboarding costs. Onboarding a single, small value user simply does not make sense unless fees are quite elevated. Exchanges end up over-charging large volume traders such as B2C2’s clients, another incentive to switch to OTC execution. In the alternative, what if crypto exchanges focus on HFT traders? In my opinion, the CME is a much better venue for institutional takers as fees are much lower and conventional trading firms will already be connected to it. My hypothesis is that most exchanges will not be able to compete with the CME for fast traders (after all, the CBOE itself gave up), and must cater to their retail user base instead. In a future post, we will explore other microstructures beyond all-to-all exchanges and bilateral OTC trading. Fiber threads image via Shutterstock
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.

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.

What is Ren? Ren is an open protocol that enables the permissionless transfer of value between any blockchain. Ren's core product, RenVM, brings interoperability to decentralized finance (DeFi). What makes RenVM unique is that it does everything in secret using zero-knowledge proofs over an sMPC based protocol that the team has pioneered. The state, inputs, and outputs of all programs that RenVM runs are kept hidden from everyone, including the Darknodes that power it. This allows RenVM to securely manage (ECDSA) private keys on different blockchains, making it possible to shift tokens between these blockchains in a trustless, permissionless, and decentralized way (i.e interoperability). Technically speaking RenVM is a byzantine fault-tolerant protocol (with 1/3 malicious nodes) that does ECDSA threshold key generation and signing via sMPC. RenVM is not a product or an application in and of itself but is a network (and an accompanying SDK) that allows developers to bring interoperability to their DeFi applications. Ren was founded in 2017 and is headquartered in Singapore.
Darknodes Darknodes are the physical machines that power RenVM, where every machine contributes CPU time for compute power and its disk space for storage. These are that machines that form the P2P decentralized network (not a blockchain) that cooperate to run secret multiparty computations. It is important to note that programs executing on RenVM are hidden from the Darknodes that run the virtual machine. This guide will walk you through the installation of your Darknode. Before you begin, make sure that you have a MacOS, Windows, or Ubuntu machine available (i.e. home computer) and 100,000 REN. Guides: How to set up a Darknode The Team
What happened to the Republic Protocol? Republic Protocol was rebranded to Ren to reflect the project’s evolution towards interoperability (i.e. RenVM). Old posts and discussions can be found on the Republic Protocol Reddit
We truly appreciate our community, and this cannot be said enough. The level of technical understanding and subsequent assistance provided to our newcomers, speaks to the expertise and positivity in the community, and we couldn’t be more thankful.

ERC. money are able to bridge businesses with crypto owners
2090 cryptocurrencies are listed on Coinmarketcap as of writing. According to the Cambridge study conducted with Visa last sprint, 2.9 to 5.8 million active cryptocurrency wallet holders. Steve Wozniak is co-founding a crypto-asset investment firm. Alibaba and IBM have the most blockchain patents in the world. Binance made more in profit in Q2 2018 than Deutsche Bank. Even Katy Perry painted her nails in Monero and Light coin to come at you like a Dark Horse. Cryptocurrencies is the safest form of a digital currency powered by an immutable, distributed, open-source technology—Blockchain. But then why haven’t the Global Financial system switched to crypto yet? At least the e-commerce? The answer is that it takes time for innovation to go through the adaptation period, and it takes innovation. Business owners need to be ready to accept. But they don’t want to learn about all the latest forks and airdrops to process transactions. That’s why they choose Visa today. Because despite the fact that every transaction cost them from 3-5%, they work auto-magically. Crypto payments are safe but an average Bitcoin transaction speed can take up to 8 minutes. Some Ethereum transactions may take hours if the sender didn’t provide a lucrative amount of gas to miners. Transaction commissions keep growing and mining pools that entered the game at the early stages control the future of communities. Yes, cryptos are innovative but unless they solve the real world problems they will continue to be the currency of computer enthusiasts on Bitcoin Talk, drug-dealers, and traders. ECR.money comes to help real business owners embrace the future of financial communications. It was launched on January 1, 2018 to change rules of the game in the world of encrypted digital payments.
“We are entrepreneurs, too. We understand the Status Quo but we need a less painful system for secure international transactions. Why launch another pointless ICO or TGE, when we can just take the real businesses and help them? Why they should pay monstrous fees for fast and secure transactions if the technology is here and ready to use? This whole token offering gold rush seems over-exaggerated to me.” – Dmitry Vasadin, Founder.
ECR team has created a network with a 100 transactions per second bandwidth. They plan to grow the speed responding to community growth. Each transaction is free. Each is protected with a Skrypt encryption protocol. ECR.nodes could be launched on computers with just 1Ghz of processing speed and 2Gb of RAM memory. Node owners only have to sign the transactions to secure the trust in the network’s distribution. Which means that the network can scale fast. That many ECR coins were pre-mined. No more coins will ever be emitted So there is no competition for block rewards. ECR.money propose to business owners a practical tool to transact on a daily basis and open their doors to an audience of millions active crypto users. You can create your first ECR crypto wallet at www.ecr.money. Learn more about how to set up your ECR wallet in this guide or check out ECR Whitepaper.
