String

func (*ValidatorSet) TotalVotingPower 

func (valSet *ValidatorSet) TotalVotingPower() int64

TotalVotingPower returns the sum of the voting powers of all validators.

func (*ValidatorSet) Update 

func (valSet *ValidatorSet) Update(val *Validator) (updated bool)

Update updates val and returns true. It returns false if val is not present in the set.

func (*ValidatorSet) VerifyCommit 

func (valSet *ValidatorSet) VerifyCommit(chainID string, blockID BlockID, height int64, commit *Commit) error

Verify that +2/3 of the set had signed the given signBytes

func (*ValidatorSet) VerifyCommitAny 

func (valSet *ValidatorSet) VerifyCommitAny(newSet *ValidatorSet, chainID string,
	blockID BlockID, height int64, commit *Commit) error

VerifyCommitAny will check to see if the set would be valid with a different validator set.

valSet is the validator set that we know * over 2/3 of the power in old signed this block

newSet is the validator set that signed this block

  • only votes from old are sufficient for 2/3 majority in the new set as well

That means that: * 10% of the valset can't just declare themselves kings * If the validator set is 3x old size, we need more proof to trust

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 int64, round int, type_ byte, valSet *ValidatorSet) *VoteSet

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

func (*VoteSet) AddVote 

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 NOTE: Vote must not be nil

func (*VoteSet) GetByAddress 

func (voteSet *VoteSet) GetByAddress(address string) *Vote

func (*VoteSet) GetByIndex 

func (voteSet *VoteSet) GetByIndex(valIndex int) *Vote

NOTE: if validator has conflicting votes, returns "canonical" vote

func (*VoteSet) HasTwoThirdsAny 

func (voteSet *VoteSet) HasTwoThirdsAny() bool

func (*VoteSet) MarshalJSON 

func (voteSet *VoteSet) MarshalJSON() ([]byte, error)

Marshal the VoteSet to JSON. Same as String(), just in JSON, and without the height/round/type_ (since its already included in the votes).

func (*VoteSet) Round 

func (voteSet *VoteSet) Round() int

func (*VoteSet) SetPeerMaj23 

func (voteSet *VoteSet) SetPeerMaj23(peerID P2PID, blockID BlockID) error

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) String 

func (voteSet *VoteSet) String() string

func (*VoteSet) TwoThirdsMajority 

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