NANO (XNO)

Nano is a peer-to-peer open-source cryptocurrency.
The currency is based on a directed acyclic graph data structure and distributed ledger, making it possible for Nano to work without intermediaries.
To agree on what transactions to commit (i.e.
achieving consensus), it uses a system called "Open Representative Voting" with weight based on the amount of currency accounts hold.Nano was launched in October 2015 by Colin LeMahieu to address the Bitcoin scalability problem.
Solving the problem means that transaction fees and confirmation time under load can be decreased. [+]
