BIP324 defines opportunistically encrypted, authenticated-encryption transport for Bitcoin P2P messages, primarily raising the cost of passive surveillance and undetected manipulation.
It encrypts the link but does not prove the peer's real-world identity. [BIP 324 — Version 2 P2P Encrypted Transport Protocol] [Bitcoin Optech — Version 2 P2P transport]
The handshake is designed to resemble random traffic and includes downgrade resistance when both peers support v2. [BIP 324 — Version 2 P2P Encrypted Transport Protocol] [Bitcoin Core — P2P v2 transport]
Encryption does not replace consensus validation or prevent an active adversary from blocking connections. [Bitcoin Optech — Version 2 P2P transport] [Bitcoin Core — P2P v2 transport]
It encrypts the link but does not prove the peer's real-world identity. [Bitcoin Core — P2P v2 transport] [Bitcoin Core — P2P processing]
