P2P
A network architecture where participants communicate directly with each other without a central intermediary. Bitcoin uses peer-to-peer technology to enable trustless transactions between any two parties in the world.
In a peer-to-peer network, every participant is both a client and a server. There is no central authority that routes messages, validates transactions, or can be shut down by a single decision. Each node connects directly to other nodes, forming a resilient and distributed network. This stands in contrast to the client-server model used by banks, payment processors like PayPal, and most internet services, where a central company controls the infrastructure and can freeze accounts, censor transactions, or fail entirely.
Bitcoin was designed from the ground up as a peer-to-peer electronic cash system. When you send Bitcoin, your transaction is broadcast directly to the network without passing through any company or gatekeeper. Nodes across the globe independently validate it according to the Bitcoin protocol rules and include it in the blockchain. No single party can prevent a valid transaction from being processed.
The peer-to-peer nature of Bitcoin is not just a technical detail. It is what makes censorship resistance and permissionless access possible. Anyone with an internet connection and a compatible wallet can participate in the Bitcoin network without asking permission from any bank, government, or institution.
