Flow is a blockchain network designed to enable transactions that are fast and affordable.

FCL (Flow Client Library)

P2P (Peer-to-peer)

P2P represents a transaction model that interacts directly without an intermediary. For Dapper purchases, they happen directly with two parties that are “peers” as Flow Accounts on the Flow network.
