A peer-to-peer (P2P) network is a decentralized system where devices (or peers) connect and share data directly with each other, without a central server. Each device can act as both a client and a server, making the network more efficient and resistant to failure.
P2P technology is what allows blockchains like Bitcoin and Ethereum to function. Every node in the network shares part of the responsibility for storing data and verifying transactions. This direct communication is also essential during crypto wallet recovery, where connecting to the right peers helps sync data and access up-to-date blockchain information.
