''' As the world’s leading regulatory compliant digital asset exchange, Coinbase sets one of the most stringent requirements for digital asset listing which includes technical evaluation of projects, legal and risk analysis, market supply and demand analysis, and crypto-economics. Coinbase holds a strong reputation in the digital asset industry, and thus the “Coinbase Standard” is considered as the industry benchmark for other digital asset projects, and the market has even seen the “Coinbase effect”. On July 25 2020, Coinbase quietly launched the pricing chart of a decentralized oracle project, NEST Protocol (NEST), into its portal. Although Coinbase has yet to announce the inclusion of the project in its evaluation list, it represents a keen interest in the DeFi sector, and particularly in the DeFi price oracle projects. NEST Protocol is the rising star in the decentralized price oracle sector Decentralized financial services offered by the current mainstream DeFi platforms such as MakerDAO, Compound, dYdX, etc. rely heavily on the market data provided by the oracle projects. Oracle projects act as reliable information sources to feed these price data to other DeFi Projects, connecting the price data from the centralized world to the DeFi space. As such, the price oracle is an integral part of the decentralized financial services infrastructure. Traditionally, the price oracle collects data from different platforms and feeds these data points to the DeFi space to create data reference points to enable them to function properly. However, many problems currently exist in the DeFi space, for example, blockchain network congestion, malicious attacks, wild market fluctuations, and other factors that may cause the data given by the price oracle to deviate from the true market data. These ultimately cause users to trade on wrong information in the DeFi space and increases such transaction costs. Decentralized finance requires a fast, secure, and reliable price oracle. The birth of the decentralized price oracle is the embodiment of the blockchain industry’s thinking, and the current market projects offering decentralized price oracle services which includes NEST Protocol, Chainlink, Band Protocol, Tellor, Witness, Oraclize, and many others. The innovation of NEST-Price is that every data point has been agreed upon by market validators, in line with the blockchain consensus mechanism. NEST-Price synchronizes the off-chain price in a highly decentralized manner, creating real and valid price data on-chain. This is the unique differentiator between NEST-Price and other price oracles. Compared with other price oracle projects, NEST also has other features and advantages, such as the proposed peer-to-peer quotation matching as well as its unique verifier verification structure, making NEST more resilient to malicious attacks, resulting in a more decentralized network, and it’s on-chain prices closer to the fair market price. All of this has resulted in the NEST Protocol becoming a rising star in the DeFi price oracle sector. HBTC.com selects high-quality projects to list and partnering with NEST to promote the development of DeFi ecosystem During the selection of quality assets, exchanges like [HBTC.com]1 and Coinbase adhere to the principle of a rigorous selection of assets from different projects to enable a proper range of digital assets. At the same time, in order to solve existing pain points in the digital asset industry, which currently lacks a market-making management solution, HBTC.com also has launched its own “coin listing crowdsourcing [liquidity initiative]2 “, redefining the exchange market making model. HBTC.com, through its coin listing strategy, effectively reduces the problem of low liquidity in the early stages of high-quality projects, ensuring the smoothness of the user experience, and achieves a win-win situation for traders, the community, and the respective trading platform. These initiatives, coupled with reliable user protection and a responsible attitude, have earned a positive reputation among users. Since its inception, the HBTC.com exchange has been committed to the discovery of both quality and promising digital asset projects. At a time when DeFi is growing rapidly, HBTC.com has a unique perspective for the decentralized price oracle sector and has prioritized NEST as a premium partner to debut the project alongside with its global branding upgrade. In addition, HBTC.com has [100% proof of reserves]3 for traders to validate the existence of assets via the Merkle tree, which brings transparency to the extreme. In May 2020, NEST token delivered a 883.29% of return, at its peak, after its global debut on HBTC.com. At present, HBTC Exchange addresses holding NEST token accounts in a total of 141 million, ranked first in the overall network. At the same time, the HBTC Exchange network exclusively releases NEST staking mining and data show that NEST 24-hour turnover has reached $20.4 million. Post-listing of the NEST token, HBTC.com has also listed DeFi projects such as DF, OKS, NEST, SWTH, JST, NVT, and other DeFi projects with market potential; some projects have achieved astonishing performance in the secondary market. HBTC.com’s path to DeFi: developing public chains to prepare for the future ecosystem breakout. In terms of the DeFi product and ecosystem infrastructure, HBTC has deployed HBTC Chain since launched in 2018, an infrastructure designed for decentralized finance and DeFi business with patented Bluehelix decentralized cross-chain clearing and custody technology. The HBTC Chain is the DeFi ecosystem infrastructure that the team has spent a significant amount of effort to build. It is based on decentralization and community consensus and integrates cryptography and blockchain technologies to support decentralized association-based governance capabilities at the technical level. Based on decentralized key management, combining various cryptography tools including ECDSA, commitment, zero-knowledge proof, and multi-party computation, It implements the distributed private key generation and signature for cross-chain assets among all validators. On top of that, this technology can realize light-weight and non-intrusive cross-chain asset custody. On the clearing layer, HBTC Chain employs BHPOS consensus and horizontal sharding mechanisms to achieve high-performing transaction clearing, and implementation of OpenDex protocol to help the development of the DeFi ecosystem. In addition, with the success experience of Bluehelix Cloud SaaS and white label solutions and the HBTC Brokerage system, HBTC’s public chain also innovatively supports CEX+DEX mixed matchmaking model and OpenDex protocol and proposes the three-tier node system which consists of standard node + consensus node + core node. This structure provides HBTC public chain certain advantages in terms of performance and cross-chain transactions. Users can easily establish a DEX with OpenDex protocol at nearly zero cost, and all DEX will share the liquidity and support customized user interface and trading parameters. The trading experience can be completely comparable to centralized spot exchanges. With the launch of its test network, it is now possible to develop various DeFi applications on the HBTC public chain, such as decentralized swap, so that private keys are not controlled by any party; no KYC, which can prevent personal information leakage; and asset security through the setting of invalidation, cancellation of transactions and other functions, cross-chain asset mappings, such as the ability to issue cross-chain cBTC or other chain tokens, fully decentralized asset mapping contracts, and 100% reserves. Conclusion In the past few months, the DeFi market has been extremely active, the price of DeFi tokens has been rising, and a new round of competition with the centralized exchanges has started. HBTC Chain relies on the powerful technology of Bluehelix and [HBTC.com]1 , giving all public chains the ability to interconnect, and put into both DeFi and SaaS levels. Undoubtedly, as one of the first exchanges to build the DeFi ecosystem, HBTC is leading the breakout in the current DeFi craze and has now become the first choice of users to engage with quality DeFi projects.

Bitcoin Cash Hard Fork 15 May 2019 | Know Everything About Upcoming BCH Fork
https://preview.redd.it/idsupgh4k7y21.png?width=1500&format=png&auto=webp&s=0a00b768fdbad52a99bfb7f041c79e109d2b1c44 The price of Bitcoin Cash (BCH) surged dramatically once the news of the upcoming Bitcoin Cash fork came out. BCH broke over 300 USD with an increase of 13% as the news of Schnorr upgrade broke the internet and the crypto space. Schnorr upgrade was initially being proposed by Peter Wuille, the Blockstream co-founder. The Bitcoin Cash community has voted for the Schnorr upgrade unlike their criticism on the past discussions on Lightning, Segregated Witnesses (SegWit) and other technologies. The Bitcoin Cash hard fork date scheduled is on May 15, 2019. Before that, a testnet has already been launched, which will help the developers test before the official launch. You can track the BCH hard fork time here, where you can find Bitcoin Cash hard fork countdown. Alysssa Hertig tweeted from CoinDesk that this change is going to be phenomenal, and is widely supported by the community members:
Let us understand what difference would it make to the BCH fork 2019 after the Schnorr Upgrade:
Cryptographically, to prove that you own Bitcoin and in order to send funds to others, you “sign” with a private key, which as of now, uses Elliptic Curve Digital Signature Algorithm (ECDSA) scheme which lacked scalability and privacy features. But Schnorr signatures will be able to verify several signatures at once, which is way faster than even verifying one signature eight times, which in turn will improve scalability and privacy, wherein there would be certain anonymity. Schnorr signatures will aggregate the signatures, public keys and messages of multiple transactions into one, enabling faster transactions.

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

Did you know that LISK uses Schnorr signature-based Ed25519 scheme which is more secure, much faster, more scalable than secp256k1 which is used by Bitcoin, Ethereum, Stratis
Schnorr signatures have been praised by Bitcoin developers for a while Adam Back admitted it was more secure https://bitcointalk.org/index.php?topic=511074.msg5727641#msg5727641 And it is much faster (scalable for verifying hundred thousands of transactions per second) https://bitcointalk.org/index.php?topic=103172.0 DJB and friends claim that with their ed25519 curve (the "ed" is for Edwards) and careful implementation they can do batch verification of 70,000+ signatures per second on a cheap quad-core Intel Westmere chip, which is now several generations old. Given advances in CPUs over time, it seems likely that in the very near future the cited software will be capable of verifying many hundreds of thousands of signatures per second even if you keep the core count constant. But core counts are not constant - it seems likely that in 10 years or so 24-32 core chips will be standard even on consumer desktops. At that point a million signatures per second or more doesn't sound unreasonable. Gavin Andresen, the former Bitcoin Chief Scientist want to support it in Bitcoin https://www.reddit.com/Bitcoin/comments/2jw5pm/im_gavin_andresen_chief_scientist_at_the_bitcoin/clfp3xj/ Bitcoin developers discussed to include it https://github.com/bitcoin-core/secp256k1/pull/212 However, it is still in wishlist https://en.bitcoin.it/wiki/Softfork_wishlist Ed25519 is used in Tahoe-FS, one of most respected crypto project https://moderncrypto.org/mail-archive/curves/2014/000069.html LISK is IoT friendly The good feature of Schnorr signature is that by design it does not require lot of computations on the signer side. Therefore, you can use it even on a computationally weak platform (think of a smart card or RFID), or on a platform with no hardware support for multiple precision arithmetic. Advantages of Schnorr signatures According to David Harding, Schnorr signatures can bring many benefits Smaller multisig transactions Slightly smaller for all transactions Plausible deniability for multisig Plausible deniability of authorized parties using a third-party organizer (which doesn't need to be trusted with private keys), it's possible to prevent signers from knowing whether their private key is part of the set of signing keys.

Faster signature verification: it likely takes fewer CPU cycles to verify an ed25519 Schnorr signature than a secp256k1 ECDSA signature. Multi-crypto multisig: with two (slightly) different cryptosystems to choose from, high-security users can create 2-of-2 multisig pubkey scripts that require both ECDSA and Schnorr signatures, so their bitcoins can't be stolen if only one cryptosystem is broken. https://bitcoin.stackexchange.com/questions/34288/what-are-the-implications-of-schnorr-signatures Scalable multisig transactions The magic of Schnorr signatures is most evident in their ability to aggregate signatures from multiple inputs into a single one to be validated for every individual transactions.

Viacoin is an open source cryptocurrency project, based on the Bitcoin blockchain. Publicly introduced on the crypto market in mid 2014, Viacoin integrates decentralized asset transaction on the blockchain, reaching speeds that have never seen before on cryptocurrencies. This Scrypt based, Proof of Work coin was created to try contrast Bitcoin’s structural problems, mainly the congested blockchain delays that inhibit microtransaction as this currency transitions from digital money to a gold-like, mean of solid value storage. Bitcoin Core developers Peter Todd and Btc have been working on this currency and ameliorated it until they was able to reach a lightning fast speed of 24 second per block. These incredible speeds are just one of the features that come with the implementation of Lightning Network, and and make Bitcoin slow transactions a thing of the past. To achieve such a dramatic improvement in performance, the developers modified Viacoin so that its OP_RETURN has been extended to 80 bytes, reducing tx and bloat sizes, overcoming multi signature hacks; the integration of ECDSA optimized C library allowed this coin to reach significant speedup for raw signature validation, making it perform up to 5 times better. This will mean easy adoption by merchants and vendors, which won’t have to worry anymore with long times between the payment and its approval. Todd role as Chief Scientist and Advisor has been proven the right choice for this coin, thanks to his focus on Tree Chains, a ground breaking feature that will fix the main problems revolving around Bitcoin, such as scalability issues and the troubles for the Viacoin miners to keep a reputation on the blockchain in a decentralized mining environment. Thanks to Todd’s expertise in sidechains, the future of this crypto currency will see the implementation of an alternative blockchain that is not linear. According to the developer, the chains are too unregulated when it comes to trying to establish a strong connection between the operations happening on one chain and what happens elsewhere. Merged mining, scalability and safety are at risk and tackling these problems is mandatory in order to create a new, disruptive crypto technology. Tree Chains are going to be the basis for a broader use and a series of protocols that are going to allow users and developers to use Viacoin’s blockchain not just to mine and store coins, but just like other new crypto currencies to allow the creation of secure, decentralized consensus systems living on the blockchain The commander role on this BIP9 compatible coin’s development team has now been taken by a programmer from the Netherlands called Romano, which has a great fan base in the cryptocurrency community thanks to his progressive views on the future of the world of cryptos. He’s in strong favor of SegWit, and considers soft forks on the chain not to be a problem but an opportunity: according to him it will provide an easy method to enable scripting upgrades and the implementation of other features that the market has been looking for, such as peer to peer layers for compact block relay. Segregation Witness allows increased capacity, ends transactions malleability, makes scripting upgradeable, and reduces UTXO set. Because of these reasons, Viacoin Core 0.13 is already SegWit ready and is awaiting for signaling. Together with implementation of SegWit, Romano has recently been working on finalizing the implementation of merged mining, something that has never been done with altcoins. Merged mining allows users to mine more than one block chain at the same time, this means that every hash the miner does contributes to the total hash rate of all currencies, and as a result they are all more secure. This release pre-announcement resulted in a market spike, showing how interested the market is in the inclusion of these features in the coin core and blockchain. The developer has been introducing several of these features, ranging from a Hierarchical Deterministic key (HD key) generation that allows all Viacoin users to backup their wallets, to a compact block relay, which decreases block propagation times on the peer to peer network; this creates a healthier network and a better baseline relay security margin. Viacoin’s support for relative locktime allows users and miners to time-lock a transaction, this means that a new transaction will be prevented until a relative time change is achieved with a new OP code, OP_CHECKSEQUENCEVERITY, which allows the execution of a script based on the age of the amount that is being spent. Support for Child-Pays-For-Parent procedures in Viacoin has been successfully enabled, CPFP will alleviate the problem of transactions that stuck for a long period in the unconfirmed limbo, either because of network bottlenecks or lack of funds to pay the fee. Thanks to this method, an algorithm will selects transactions based on federate inclusive unconfirmed ancestor transaction; this means that a low fee transaction will be more likely to get picked up by miners if another transaction with an higher fee that speeds its output gets relayed. Several optimizations have been implemented in the blockchain to allow its scaling to proceed freely, ranging from pruning of the chain itsel to save disk space, to optimizing memory use thanks to mempool transaction filtering. UTXO cache has also been optimization, further allowing for significant faster transaction times. Anonymity of transaction has been ameliorated, thanks to increased TOR support by the development team. This feature will help keep this crypto currency secure and the identity of who works on it safe; this has been proven essential, especially considering how Viacoin’s future is right now focused on segwit and lightning network . Onion technology used in TOR has also been included in the routing of transactions, rapid payments and instant transaction on bi directional payment channels in total anonymity. Payments Viacoin’s anonymity is one of the main items of this year’s roadmap, and by the end of 2017 we’ll be able to see Viacoin’s latest secure payment technology, called Styx, implemented on its blockchain. This unlinkable anonymous atomic payment hub combines off-the-blockchain cryptographic computations, thanks to Viacoin’s scriptin functionalities, and makes use of security RSA assumptions, ROM and Elliptic Curve digital signature Algorithm; this will allow participants to make fast, anonymous transfer funds with zero knowledge contingent payment proof. Wallets already offer strong privacy, thanks to transactions being broadcasted once only; this increases anonymity, since it can’t be used to link IPs and TXs. In the future of this coin we’ll also see hardware wallets support reaching 100%, with Trezor and Nano ledger support. These small, key-chain devices connect to the user’s computer to store their private keys and sign transactions in a safe environment. Including Viacoin in these wallets is a smart move, because they are targeted towards people that are outside of hardcore cryptocurrency users circle and guarantees exposure to this currency. The more casual users hear of this coin, the faster they’re going to adopt it, being sure of it’s safety and reliability. In last October, Viacoin price has seen a strong decline, probably linked to one big online retailer building a decentralized crypto stock exchange based on the Counterparty protocol. As usual with crypto currencties, it’s easy to misunderstand the market fluctuations and assume that a temporary underperforming coin is a sign of lack of strength. The change in the development team certainly helped with Viacoin losing value, but by watching the coin graphs it’s easy to see how this momentary change in price is turning out to be just one of those gentle chart dips that precede a sky rocketing surge in price. Romano is working hard on features and focusing on their implementation, keeping his head low rather than pushing on strong marketing like other alt coins are doing. All this investment on ground breaking properties, most of which are unique to this coin, means that Viacoin is one of those well kept secret in the market. Minimal order books and lack of large investors offering liquidity also help keep this coin in a low-key position, something that is changing as support for larger books is growing. As soon as the market notices this coin and investments go up, we are going to see a rapid surge in the market price, around the 10000 mark by the beginning of January 2018 or late February. Instead of focusing on a public ICO like every altcoin, which means a sudden spike in price followed by inclusion on new exchanges that will dry up volume, this crypto coin is growing slowly under the radar while it’s being well tested and boxes on the roadmap get checked off, one after the other. Romano is constantly working on it and the community around this coin knows, such a strong pack of followers is a feature that no other alt currency has and it’s what will bring it back to the top of the coin market in the near future. His attitude towards miners that are opposed to SegWit is another strong feature to add to Viacoin, especially because of what he thinks of F2Pool and Bitmain’s politics towards soft forks. The Chinese mining groups seem scared that once alternative crypto coins switch to it they’re going to lose leveraging power for what concerns Bitcoin’s future and won’t be able to speculate on the mining and trading market as much as they have been doing in the past, especially for what concerns the marketing market. It’s refreshing to see such dedication and releases being pushed at a constant manner, the only way to have structural changes in how crypto currencies work can only happen when the accent is put on development and not on just trying to convince the market. This strategy is less flashy and makes sure the road is ready for the inevitable increase in the userbase. It’s always difficult to forecast the future, especially when it concerns alternative coins when Bitcoin is raising so fast. A long term strategy suggestion would be to get around 1BTC worth of this cryptocoin as soon as possible and just hold on it: thanks to the features that are being rolled in as within 6 months there is going to be an easy gain to be made in the order of 5 to 10 times the initial investment. Using the recent market dip will make sure that the returns are maximized. What makes Viacoin an excellent opportunity right now is that the price is low and designed to rise fast, as its Lightning Network features become more mainstream. Lightning Network is secure, instant payment that aren’t going to be held back by confirmation bottlenecks, a blockchain capable to scale to the billions of transactions mark, extremely low fees that do not inhibit micropayments and cross-chain atomic swap that allow transaction across blockchain without the need of a third party custodians. These features mean that the future of this coin is going to be bright, and the the dip in price that started just a while ago is going to end soon as the market prepares for the first of August, when when the SegWit drama will affect all crypto markets. The overall trend of viacoin is bullish with a constant uptrend more media attention is expected , when news about the soft fork will spread beyond the inner circle of crypto aficionados and leak in the mainstream finance news networks. Solid coins like Viacoin, with a clear policy towards SegWit, will offer the guarantees that the market will be looking for in times of doubt.
