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.
Waves is an open blockchain platform designed for ease of use and mass adoption. Anyone can use Waves to launch, distribute and trade their own crypto token. The platform is fully decentralised, transparent and auditable. Waves is inspired by NXT with team members previously being involved with NXT. Its name is inspired by the gravitational waves discovery. It is a cryptocurrency platform that had been coded for scratch and allows for asset issuance, decentralized crowdfunding, community management and encrypted messaging. Waves is creating a comprehensive blockchain ecosystem that will provide all the necessary features for business adoption, and the platform already has a number of powerful tools and services that make building user applications straightforward. Waves is a Proof-of-Stake cryptocurrency that conducted its ICO from 12 April 2016 to 31 May 2016. It raised a total of $16 million worth of bitcoins during the ICO. There is a total of 100 million tokens of which 15 million tokens are reserved for bounties and the development team while the remaining 85 million tokens are distributed to ICO participants.
