# Mempool Reactor
|

|
|
## Channels

See [this issue](https://github.com/tendermint/tendermint/issues/1503)
|
|
|
|
Mempool maintains a cache of the last 10000 transactions to prevent
|
|
replaying old transactions (plus transactions coming from other
|
|
validators, who are continually exchanging transactions). Read [Replay
|
|
Protection](../../../app-dev/app-development.md#replay-protection)
|
|
for details.
|
|
|
|
Sending incorrectly encoded data or data exceeding `maxMsgSize` will result
|
|
in stopping the peer.
|
|
|
|
The mempool will not send a tx back to any peer which it received it from.
|
|
|
|
The reactor assigns an `uint16` number for each peer and maintains a map from
|
|
p2p.ID to `uint16`. Each mempool transaction carries a list of all the senders
|
|
(`[]uint16`). The list is updated every time mempool receives a transaction it
|
|
is already seen. `uint16` assumes that a node will never have over 65535 active
|
|
peers (0 is reserved for unknown source - e.g. RPC).
