Evidence is used to identify validators who have or are acting malicious. There are multiple types of evidence, to read more on the evidence types please see Evidence Types.

The evidence reactor works similar to the mempool reactor. When evidence is observed, it is sent to all the peers in a repetitive manner. This ensures evidence is sent to as many people as possible to avoid sensoring. After evidence is received by peers and committed in a block it is pruned from the evidence module.

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