BIP 324 proposed encrypted transport for Bitcoin peer connections
BIP 324 specifies an encrypted P2P transport protocol designed to make Bitcoin network traffic less easily classified and tampered with in transit.
Transport encryption can improve resistance to some network observation and interference while keeping Bitcoin’s block-validation rules unchanged.
The proposal separates network-privacy improvements from transaction-consensus changes, showing that protocol privacy has several layers.
Encryption does not hide all metadata or protect a compromised endpoint; it is one defense in a broader privacy model.
