- Format: `enode://<public-key>@<ip>:<port>`, cryptographic identity + network location in one URL.

Format: enode://<public-key>@<ip>:<port>, cryptographic identity + network location in one URL.

The public key prevents man-in-the-middle attacks: nodes verify identity during the RLPx handshake.

IP must be explicit: Besu doesn't resolve Docker hostnames inside enode URLs.

The single most critical piece of information for joining a network: who + where.

Mismatched public key → connection rejected during handshake.
