Each account has their own blockchain
With Nano, each account has their own blockchain as part of a larger directed acyclic graph.
Each individual user provides the computational power for the verification of their own transactions, meaning entire network is not required to update the overall ledger together in massive blocks.
Wallets pre-cache the anti-spam Proof of Work
Wallets pre-cache the anti-spam Proof of Work for the next transaction once a transaction is sent, making transactions instantaneous, as both sides have the proof of work ready to go.
Running a node costs next to nothing
Because the protocol is incredibly lightweight and running a node costs next to nothing, Nano’s transactions are processed with no fees.
One transaction fits within a single UDP packet, and transactions are handled independently, eliminating any block size issue.
