Nano is a cryptocurrency developed by the Nano Foundation and open source contributers. This community is building a feeless, instant, global currency over a secure, scalable, energy efficient and decentralised network.
Nano's network is built around the Block-Lattice architecture (a form of DAG), in which each account has its own blockchain. When a transaction occurs on the Block-Lattice, a block is added onto the sender's and receiver's blockchains asyncronously; other accounts' blockchains are not effected. This approach makes Nano extremely fast and scalable.
