	tmtypes.Proposal
}

Proposal defines a block proposal for the consensus. It refers to the block only by its PartSetHeader. It must be signed by the correct proposer for the given Height/Round to be considered valid. It may depend on votes from a previous round, a so-called Proof-of-Lock (POL) round, as noted in the POLRound and POLBlockID.

	// contains filtered or unexported fields
}

ValidatorSet represent a set of *Validator at a given height. The validators can be fetched by address or index. The index is in order of .Address, so the indices are fixed for all rounds of a given blockchain height. On the other hand, the .AccumPower of each validator and the designated .GetProposer() of a set changes every round, upon calling .IncrementAccum(). NOTE: Not goroutine-safe. NOTE: All get/set to validators should copy the value for safety. TODO: consider validator Accum overflow
