BIP-324 (v2 P2P Transport)
Network● Common
A protocol upgrade enabling encrypted and authenticated peer-to-peer communication between Bitcoin nodes. Prevents ISPs and network observers from detecting Bitcoin traffic or tampering with messages.
Technical Notes
Uses ElligatorSwift for key exchange, ChaCha20-Poly1305 for encryption. Opportunistic encryption (no identity verification by default). Session IDs enable optional identity binding. Counters traffic analysis with shapable packet sizes.
