Peer Discovery Protocol

A peer discovery protocol is the mechanism by which nodes in a decentralized network find and connect to other nodes. This is the foundation of network connectivity, enabling the propagation of transactions and blocks.

Without an effective discovery protocol, the network would become fragmented and unable to reach consensus. It must be resilient to attacks, such as sybil attacks, where a malicious actor creates many fake identities.

Robust discovery ensures that nodes can quickly establish reliable connections, maintaining the decentralization and health of the system. It is a critical component of the underlying networking stack that allows blockchain protocols to operate globally.
