DISABLETX (BIP-338)
Network● Common
A P2P message indicating a connection will not relay transactions. Enables explicit block-only connections, reducing resource usage and preventing certain classes of attacks.
Technical Notes
Sent during version handshake. If both peers send, neither sends tx-related messages. Saves: bloom filter allocation, mempool sync bandwidth, fee filter messages. Formalized existing block-relay-only behavior.
