Peer-to-peer (P2P) computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes.
Peer-to-peer (P2P) service is a decentralized platform whereby two individuals interact directly with each other, without intermediation by a third party. Instead, the buyer and the seller transact directly with each other via the P2P service.
10 years ago I'm addicted of online games so in order to have a strong character you need to purchased a good armor and weapon. Some players are crafter so we bought stuffs from them. It's peer to peer transaction. So you can crush your enemies while having pvp.
