Peer-to-peer networks, often shortened as P2P, offer an essential component to blockchains because the core values of the network design allow for decentralization. Rather than a typical client-server model in which individual clients request services or information from a central server, a peer-to-peer network is more resilient and allows peers on the network to directly interact with other peers. Peer-to-peer networks are self-organizing and therefore can be self-sustaining. This is a significant component of decentralized systems that allow blockchains to do what they are purposed for.
