Discovery entry point: new nodes contact bootnodes to learn about other peers in the network.

Discovery entry point: new nodes contact bootnodes to learn about other peers in the network.

Not a special node type: any node can be a bootnode if others list its enode in --bootnodes.

Multiple bootnodes = resilience: if one goes down, newcomers can use others.

After initial discovery, nodes find each other through gossip. The bootnode's job is done.

Best topology: mutual bootnode pointing (A→B, B→A) + all nodes listing both.

If the only bootnode dies, existing nodes keep working (they know peers). Only newcomers are affected.
