Nano was launched in October 2015 with the aim of addressing blockchain scalability limitations that can result in restrictive fees and increased transaction confirmation times under load. It has feeless transactions that typically achieve full confirmation in under one second.

Nano uses block lattice technology, which is highly energy efficient. The Nano platform uses a system called Open Representative Voting (ORV), where account holders vote for their chosen representative, who then work to securely confirm blocks of transactions.

On the Nano platform, user accounts can be updated asynchronously, rather than needing to involve an entire linear blockchain as is the case with Bitcoin and others. Instead of competition and delays, then, Nano involves just the sender and receiver account-chains.

Nano is instant and feeless, and uses considerably less energy than Bitcoin. With the energy required to do 1 transaction with Bitcoin you can do +6M transactions with NANO. 

NANO has an active community in reddit with +125k active users and is currently listed on some important Exchanges but we are still missing some others like Coinbase, eToro, Robinhood.
