What is Nano (NANO)

Blockchains provide decentralization, but their biggest problem is scalability. Many new crypto currencies use structures which are different from blockchains. NANO is one of them. It was formerly called RaiBlocks. It uses a structure called block lattice, which is more scalable. It will have very low energy footprint, so it wont harm the environment like most proof of work currencies do. It will provide cheap and instant transactions, which will be its only focus. There are no plans to support smart contracts or more complex features.
