Peer-to-Peer Protocol

A peer-to-peer protocol is the foundational communication framework that allows nodes in a decentralized network to interact directly with one another without relying on a central server. In the context of blockchain, these protocols define the rules for how data is shared, how transactions are broadcast, and how consensus is reached.

By enabling a distributed network of participants to maintain a shared state, peer-to-peer protocols ensure the resilience and censorship resistance of the system. These protocols must be robust enough to handle malicious actors and network failures while maintaining high availability and security.

The design of these protocols directly influences the scalability and performance of the financial applications built on top of them. They are the essential communication layer that makes decentralized finance possible.
