### Vote
A vote is a signed message broadcast in the consensus for a particular block at a particular height and round.
When stored in the blockchain or propagated over the network, votes are encoded in Amino.
For signing, votes are represented via `CanonicalVote` and also encoded using amino (protobuf compatible) via

When stored in the blockchain or propagated over the network, votes are encoded in Protobuf.
For signing, votes are represented via `CanonicalVote` and also encoded using Protobuf via
`VoteSignBytes` which includes the `ChainID`, and uses a different ordering of
the fields.
We define a method `Verify` that returns `true` if the signature verifies against the pubkey for the `SignBytes`
