type ValidatorSet struct {
	Validators []*Validator // NOTE: persisted via reflect, must be exported.
	Proposer   *Validator
	// 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 TODO: move valset into an iavl tree where key is 'blockbonded|pubkey'

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 

func NewVoteSet(chainID string, height int, round int, type_ byte, valSet *ValidatorSet) *VoteSet

Constructs a new VoteSet struct used to accumulate votes for given height/round.

func (*VoteSet) AddVote added in v0.8.0 

func (voteSet *VoteSet) AddVote(vote *Vote) (added bool, err error)

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) SetPeerMaj23 added in v0.8.0 

func (voteSet *VoteSet) SetPeerMaj23(peerID string, blockID BlockID)

If a peer claims that it has 2/3 majority for given blockKey, call this. NOTE: if there are too many peers, or too much peer churn, this can cause memory issues. TODO: implement ability to remove peers too NOTE: VoteSet must not be nil

func (*VoteSet) TwoThirdsMajority 

func (voteSet *VoteSet) TwoThirdsMajority() (blockID BlockID, ok bool)

Returns either a blockhash (or nil) that received +2/3 majority. If there exists no such majority, returns (nil, PartSetHeader{}, false).
