Nano, a low-latency cryptocurrency built on an innovative block-lattice data structure offering unlimited scalability and no transaction fees. Nano by design is a simple protocol with the sole purpose of being a high-performance cryptocurrency. The Nano protocol can run on low-power hardware, allowing it to be a practical, decentralized cryptocurrency for everyday use. The original Nano (RailBlocks) paper and first beta implementation were published in December, 2014, making it one of the first Directed Acyclic Graph (DAG) based cryptocurrencies [6]. Soon after, other DAG cryptocurrencies began to develop, most notably DagCoin/Byteball and IOTA. These DAG-based cryptocurrencies broke the blockchain mold, improving system performance and security. Byteball achieves consensus by relying on a “main-chain” comprised of honest, reputable and user-trusted “witnesses”, while IOTA achieves consensus via the cumulative PoW of stacked transactions. Nano achieves consensus via a balance-weighted vote on conflicting transactions. This consensus system provides quicker, more deterministic transactions while still maintaining a strong, decentralized system. Nano continues this development and has positioned itself as one of the highest performing cryptocurrencies. Nano is a trustless, feeless, low-latency cryptocurrency that utilizes a novel blocklattice structure and delegated Proof of Stake voting. The network requires minimal resources, no high-power mining hardware, and can process high transaction throughput. All of this is achieved by having individual blockchains for each account, eliminating access issues and inefficiencies of a global data-structure. We identified possible attack vectors on the system and presented arguments on how Nano is resistant to these forms of attacks. Check out CoinBureau for the complete review of Nano.
MATRIX AI Network (MAN) is a global open-source, public, intelligent blockchain-based distributed computing platform and operating system that combines artificial intelligence (AI) and blockchain. MATRIX was created to make blockchains faster, more flexible, more secure, and more intelligent. Besides boasting an impressive 50.000 transactions per second, there are a couple of features which makes Matrix AI Network stand out from its competitors. Matrix adopts a Hybrid PoS + PoW consensus mechanism instead of the traditional Hash computations. The mechanism makes use of value-added computation through the use of the Markov Chain Monte Carlo (MCMC) computations. This computation set is to be used as the Proof-of-Work protocol. This allows the mining process to not only generate MAN tokens but to also be used to power real-world applications. Currently being used in collaboration with Beijing cancer Research hospital to improve speed and accuracy of a cancer diagnosis. While the project seems ambitious with the integration of a working AI in so many areas, the AI-part is already done. Matrix now only has to deliver a working blockchain solution. MATRIX will be launching several community activities after its testnet launch, including a Bug Bounty Program and a Dapp competition, as well as introducing the MATRIX Blockchain Browser and Online Wallet Prototype. Details and instructions will be shared over the coming weeks. Full manner is set to launch December 2018. The MATRIX mining machine is set to launch for sale end of the year 2018.
