Nano (cryptocurrency)

Nano (Abbreviation: XNO; sign: Ӿ) is a cryptocurrency characterized by 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 voting system with weight based on the amount of currency an account holds.
