Nano (NANO), formally known as RaiBlocks (XRB), is a P2P digital currency. Nano is a decentralized, freeware crypto that is hankered to directed acyclic graph (DAG) architecture and it’s launched under the FreeBSD License. It runs without having any person or intermediaries by making use of the distributed ledger that has a block-lattice data design (this is where every account has its own blockchain). This crypto was launched by Colin LeMahieu, with the main aim of addressing the limitations of blockchain scalability back in 2015. These limitations include restrictive high fees with an increase under the block confirmation time. The Nano network or the Nano blockchain has confirmations that take less than a second to complete the full blockchain confirmation. To prevent double spending fraudulent actions, and Sybil attacks (where someone creates pseudonymous accounts to generate and create popularity), it uses a process known as the delegated representative voting, an open PoS.
