Represents a prevote, precommit, or commit vote from validators for consensus.
type VoteSet ¶
type VoteSet struct {
// contains filtered or unexported fields
}
VoteSet helps collect signatures from validators at each height+round for a predefined vote type.
We need VoteSet to be able to keep track of conflicting votes when validators double-sign. Yet, we can't keep track of *all* the votes seen, as that could be a DoS attack vector.
There are two storage areas for votes. 1. voteSet.votes 2. voteSet.votesByBlock
`.votes` is the "canonical" list of votes. It always has at least one vote, if a vote from a validator had been seen at all. Usually it keeps track of the first vote seen, but when a 2/3 majority is found, votes for that get priority and are copied over from `.votesByBlock`.
`.votesByBlock` keeps track of a list of votes for a particular block. There are two ways a &blockVotes{} gets created in `.votesByBlock`. 1. the first vote seen by a validator was for the particular block. 2. a peer claims to have seen 2/3 majority for the particular block.
Since the first vote from a validator will always get added in `.votesByBlock` , all votes in `.votes` will have a corresponding entry in `.votesByBlock`.
When a &blockVotes{} in `.votesByBlock` reaches a 2/3 majority quorum, its votes are copied into `.votes`.
All this is memory bounded because conflicting votes only get added if a peer told us to track that block, each peer only gets to tell us 1 such block, and, there's only a limited number of peers.
NOTE: Assumes that the sum total of voting power does not exceed MaxUInt64.
func NewVoteSet ¶
Constructs a new VoteSet struct used to accumulate votes for given height/round.
func (*VoteSet) AddVote ¶ added in v0.9.2
Returns added=true if vote is valid and new. Otherwise returns err=ErrVote[
UnexpectedStep | InvalidIndex | InvalidAddress | InvalidSignature | InvalidBlockHash | ConflictingVotes ]
Duplicate votes return added=false, err=nil. Conflicting votes return added=*, err=ErrVoteConflictingVotes. NOTE: vote should not be mutated after adding. NOTE: VoteSet must not be nil
func (*VoteSet) BitArrayByBlockID ¶ added in v0.9.2
func (*VoteSet) GetByAddress ¶
func (*VoteSet) GetByIndex ¶
NOTE: if validator has conflicting votes, returns "canonical" vote
