## Evidence
There is currently only one kind of evidence, `DuplicateVoteEvidence`.
DuplicateVoteEvidence `ev` is valid if
- `ev.VoteA` and `ev.VoteB` can be verified with `ev.PubKey`
- `ev.VoteA` and `ev.VoteB` have the same `Height, Round, Address, Index, Type`
- `ev.VoteA.BlockID != ev.VoteB.BlockID`
- `(block.Height - ev.VoteA.Height) < MAX_EVIDENCE_AGE`
# Execution
Once a block is validated, it can be executed against the state.
