Nano (NANO), formerly known as RaiBlocks, is a low-latency, high performance cryptocurrency that is built upon a block-lattice data structure to allow for unlimited scalability and zero transaction fees. The Nano protocol can run on low-power hardware, making it practical for everyday use. Nano is also one of the first Directed Acyclic Graph (DAG) based cryptocurrencies. It achieves consensus via a balance-weighted vote on conflicting transactions to allow for quicker, more deterministic transactions while still maintaining a strong, decentralized system without the need for high-power mining hardware as each account each has an individual blockchain to eliminate access issues and the inefficiencies of a global data structure.
