Questions tagged [bootnodes]
Geth finds peers through something called the discovery protocol. In the discovery protocol, nodes are gossiping with each other to find out about other nodes on the network. In order to get going initially, geth uses a set of bootstrap nodes (or bootnodes) whose endpoints are recorded in the source code.
