The format for "mempool" packet is missing. I'm guessing that it is an empty message, right?
Might be good to add that. ----- Original Message ----- From: Jeff Garzik <jgar...@exmulti.com> To: Bitcoin Development <bitcoin-development@lists.sourceforge.net> Cc: Sent: Thursday, August 16, 2012 6:32 PM Subject: [Bitcoin-development] BIP 35: add mempool message Consensus was we should do a BIP for all P2P changes, so here it is... feedback requested. https://en.bitcoin.it/wiki/BIP_0035 Abstract ------------------------------------------- Make a network node's transaction memory pool accessible via a new "mempool" message. Extend the existing "getdata" message behavior to permit accessing the transaction memory pool. Motivation ------------------------------------------- Several use cases make it desireable to expore a network node's transaction memory pool: * SPV clients, wishing to obtain zero-confirmation transactions sent or received. * Miners, downloading existing network transactions after a restart. * Remote network diagnostics. Specification ------------------------------------------- 1) Upon receipt of a "mempool" message, the node will respond with an "inv" message containing MSG_TX hashes of all the transactions in the node's transaction memory pool. An "inv" message is always returned, even if empty. 2) The typical node behavior in response to an "inv" is "getdata". However, the reference Satoshi implementation ignores requests for transaction hashes outside that which is recently relayed. To support "mempool", an implementation must extend its "getdata" message support to querying the memory pool. 3) Feature discovery is enabled by checking two "version" message attributes: a) Protocol version >= 60002 b) NODE_NETWORK bit set in nServices Backwards compatibility ------------------------------------------- Older clients remain 100% compatible and interoperable after this change. Implementation ------------------------------------------- See https://github.com/bitcoin/bitcoin/pull/1641 -- Jeff Garzik exMULTI, Inc. jgar...@exmulti.com ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
