### Canonical vs subjective commit
We distinguish between "canonical" and "subjective" commits. The latter is what
each validator sees locally when they decide to commit a block. The former is
what is included by the proposer of the next block in the `LastCommit` field of
the block. This is what makes it canonical and ensures everyone agrees on it,
even if its different from the first +2/3 votes they saw that caused them to
commit a block. Each block contains a canonical +2/3 commit for the previous
block.
