Nano

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. It uses an ORV (Open Representative Voting) consensus algorithm, which is similar to PoS (Proof of Stake) but without inflationary rewards not locking of the native coin XNO.

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.
