+    Layer: Peer Services
+    Title: mempool message
+    Author: Jeff Garzik <jgarzik@exmulti.com>
+    Comments-Summary: No comments yet.
+    Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0035
+    Status: Final
+    Type: Standards Track
+    Created: 2012-08-16
+
+## 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 expose a network node's transaction memory pool:
+1. SPV clients, wishing to obtain zero-confirmation transactions sent or received.
+2. Miners, to avoid missing lucrative fees, downloading existing network transactions after a restart.
+3. Remote network diagnostics.
+
+## Specification
+
+1. The mempool message is defined as an empty message where pchCommand == "mempool"
+2. 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, if any.
+3. 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.
+4. Feature discovery is enabled by checking two "version" message attributes:
+   - Protocol version >= 60002
+   - NODE_NETWORK bit set in nServices
+
+Note that existing implementations drop "inv" messages with a vector size > 50000.
+
+## Backward compatibility
+
+Older clients remain 100% compatible and interoperable after this change.
+
+## Implementation

 Requests that the recipient notify the sender of transactions that are currently in its [mempool](/protocol/blockchain/memory-pool).
 Recipients of a `mempool` message MAY respond with a set of transaction hashes currently in their mempool via an [`inv`](/protocol/network/messages/inv) message.
 
+The mempool message was defined in [BIP-35](/protocol/forks/bip-0035).

 ## Message Format
 This message has no contents.
