Previously known as RaiBlocks, Nano is a coin focused on tackling the problem of scalability. As described in their whitepaper, this coin has near-instant transactions with very low fees. They operate with the motto of “do one thing and do it well.”Their goal is to give users a level of performance and scalability that is unmatched by any other platform. Nano achieves this with a unique programming structure where each account has its own unique blockchain. This allows each chain to update asynchronously to the network which results in fast transactions and minimal overhead.
