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.
'Founded by OS expert Rong Chen, Elastos is building the blockchain industry’s most comprehensive and interoperable open source platform. Using a hybrid consensus that combines the secure hashpower of Bitcoin and the democratic ideals of Delegated-Proof-of-Stake, the SmartWeb of Elastos is a suite of software for an entirely decentralized internet. Elastos employs not only blockchain technology, but a peer-to-peer network for communication, decentralized data storage services, and a decentralized ID (DID) system for all digital assets. With sidechains like Ethereum, Elastos is not merely the foundation for securing truly decentralized applications that can scale, it is the foundation for true data ownership. elastOS, the flagship product of the Elastos Smartweb, brings the entire decentralized ecosystem into a single App, currently available for Android and in development for both iOS and desktop. Elastos is also actively searching for both new and existing dApp projects through its Cyber Republic initiative. Cyber Republic possesses a community-governed grant fund designed to help startups and existing businesses explore blockchain. You can read more about Cyber Republic at https://www.cyberrepublic.org.
