+
+==Abstract==
+
+This BIP proposes a new mechanism to halt the processing of unrequested transations
+received by a node from its bitcoin networks peers.
+
+==Motivation==
+
+Historically, nodes have been exchanging transactions on the Bitcoin peer-to-peer
+network by sending an inv, and if the transaction has not been discovered and processed
+yet by the other peer, sending a dedicated tx message.
+
+Sending an unnannounced tx message has always been considered in conformity with
+the protocol, however this behavior creates a denanonymization vector if leveraged
+by mass connectors.
+
+We can eliminate this concern by nodes rejecting unrequested transactions.
+
+==Specification==
+
+TODO: segment the protocol version by sub-categories of traffic class (eg tx, addr, block ?)
+
+#. The protocol version of nodes implementing this BIP must be set to 70017 or higher.
+
+#. After a node received a transaction from a peer
+## If this transaction has been previously fetch with a getdata request, the node MUST process the transaction
+## If this transaction has not been previously fetch with a getdata request, the node SHOULD reject the transaction
+
+TODO: add a policy rule to disconnect protocol violation ?
+
+==Backward compatibility==
+
+This mechanism only applies to network peers signaling NODE_TXRELAY_V2 as a node service bit.
+
+==Implementation==
