# PEX Reactor

## Channels

Defines only `SendQueueCapacity`. [#1503](https://github.com/tendermint/tendermint/issues/1503)

Implements rate-limiting by enforcing minimal time between two consecutive
`pexRequestMessage` requests. If the peer sends us addresses we did not ask,
it is stopped.

Sending incorrectly encoded data or data exceeding `maxMsgSize` will result
in stopping the peer.
