func CanonicalTime 

func CanonicalTime(t time.Time) string

CanonicalTime can be used to stringify time in a canonical way.

func ComputeAminoOverhead 

func ComputeAminoOverhead(tx Tx, fieldNum int) int64

ComputeAminoOverhead calculates the overhead for amino encoding a transaction. The overhead consists of varint encoding the field number and the wire type (= length-delimited = 2), and another varint encoding the length of the transaction. The field number can be the field number of the particular transaction, or the field number of the parenting struct that contains the transactions []Tx as a field (this field number is repeated for each contained Tx). If some []Tx are encoded directly (without a parenting struct), the default fieldNum is also 1 (see BinFieldNum in amino.MarshalBinaryBare).

	// 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 - ie. the validators are sorted by their address. On the other hand, the .ProposerPriority of each validator and the designated .GetProposer() of a set changes every round, upon calling .IncrementProposerPriority(). NOTE: Not goroutine-safe. NOTE: All get/set to validators should copy the value for safety.

func NewValidatorSet 

func NewValidatorSet(valz []*Validator) *ValidatorSet

NewValidatorSet initializes a ValidatorSet by copying over the values from `valz`, a list of Validators. If valz is nil or empty, the new ValidatorSet will have an empty list of Validators. The addresses of validators in `valz` must be unique otherwise the function panics. Note the validator set size has an implied limit equal to that of the MaxVotesCount - commits by a validator set larger than this will fail validation.

func (*ValidatorSet) UpdateWithChangeSet 

func (vals *ValidatorSet) UpdateWithChangeSet(changes []*Validator) error

UpdateWithChangeSet attempts to update the validator set with 'changes'. It performs the following steps:

  • validates the changes making sure there are no duplicates and splits them in updates and deletes
  • verifies that applying the changes will not result in errors
  • computes the total voting power BEFORE removals to ensure that in the next steps the priorities across old and newly added validators are fair
  • computes the priorities of new validators against the final set
  • applies the updates against the validator set
  • applies the removals against the validator set
  • performs scaling and centering of priority values

If an error is detected during verification steps, it is returned and the validator set is not changed.

func (*ValidatorSet) VerifyCommit 

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

VerifyCommit verifies +2/3 of the set had signed the given commit.

It checks all the signatures! While it's safe to exit as soon as we have 2/3+ signatures, doing so would impact incentivization logic in the ABCI application that depends on the LastCommitInfo sent in BeginBlock, which includes which validators signed. For instance, Gaia incentivizes proposers with a bonus for including more than +2/3 of the signatures.

func (*ValidatorSet) VerifyCommitLight 

func (vals *ValidatorSet) VerifyCommitLight(chainID string, blockID BlockID,
	height int64, commit *Commit) error

This method is primarily used by the light client and does not check all the signatures.

func (*ValidatorSet) VerifyCommitLightTrusting 

func (vals *ValidatorSet) VerifyCommitLightTrusting(chainID string, blockID BlockID,
	height int64, commit *Commit, trustLevel tmmath.Fraction) error

VerifyCommitLightTrusting verifies that trustLevel of the validator set signed this commit.

This method is primarily used by the light client and does not check all the signatures.

NOTE the given validators do not necessarily correspond to the validator set for this commit, but there may be some intersection.

Panics if trustLevel is invalid.

func (*ValidatorSet) VerifyFutureCommit 

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

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

vals is the old validator set that we know. Over 2/3 of the power in old signed this block.

In Tendermint, 1/3 of the voting power can halt or fork the chain, but 1/3 can't make arbitrary state transitions. You still need > 2/3 Byzantine to make arbitrary state transitions.

To preserve this property in the light client, we also require > 2/3 of the old vals to sign the future commit at H, that way we preserve the property that if they weren't being truthful about the validator set at H (block hash -> vals hash) or about the app state (block hash -> app hash) we can slash > 2/3. Otherwise, the lite client isn't providing the same security guarantees.

Even if we added a slashing condition that if you sign a block header with the wrong validator set, then we would only need > 1/3 of signatures from the old vals on the new commit, it wouldn't be sufficient because the new vals can be arbitrary and commit some arbitrary app hash.

newSet is the validator set that signed this block. Only votes from new are sufficient for 2/3 majority in the new set as well, for it to be a valid commit.

NOTE: This doesn't check whether the commit is a future commit, because the current height isn't part of the ValidatorSet. Caller must check that the commit height is greater than the height for this validator set.

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 CommitToVoteSet
