-## Channel ""
+## Channels
+
+Each peer connection is multiplexed into channels.  Each channel can optionally have an associated filter which determines whether the peer already knows of the message.  The system is designed to be easily extensible for various applications.
+<hr />
+
+### Default channel
+
+The default channel is used to communicate state changes, pings, peer exchange, and other automatic internal messages that all P2P protocols would want implemented.

-## Channel "mempool"
+The mempool channel is used for broadcasting new transactions that haven't yet entered the blockchain.  It uses a lossy bloom filter on either end, but with sufficient fanout and filter nonce updates every new block, all transactions will eventually reach every node.
