For instance, Gaia incentivizes proposers with a bonus for including more than +2/3 of the signatures.

	// abci specific information

	Timestamp           time.Time    // timestamp of the block at the common height
}

LightClientAttackEvidence is a generalized evidence that captures all forms of known attacks on a light client such that a full node can verify, propose and commit the evidence on-chain for punishment of the malicious validators. There are three forms of attacks: Lunatic, Equivocation and Amnesia. These attacks are exhaustive. You can find a more detailed overview of this at tendermint/docs/architecture/adr-047-handling-evidence-from-light-client.md

CommonHeight is used to indicate the type of attack. If the height is different to the conflicting block height, then nodes will treat this as of the Lunatic form, else it is of the Equivocation form.

func LightClientAttackEvidenceFromProto 

func LightClientAttackEvidenceFromProto(lpb *tmproto.LightClientAttackEvidence) (*LightClientAttackEvidence, error)

LightClientAttackEvidenceFromProto decodes protobuf

func (*LightClientAttackEvidence) ConflictingHeaderIsInvalid 

func (l *LightClientAttackEvidence) ConflictingHeaderIsInvalid(trustedHeader *Header) bool

ConflictingHeaderIsInvalid takes a trusted header and matches it againt a conflicting header to determine whether the conflicting header was the product of a valid state transition or not. If it is then all the deterministic fields of the header should be the same. If not, it is an invalid header and constitutes a lunatic attack.

func (*LightClientAttackEvidence) GenerateABCI

func (*LightClientAttackEvidence) GetByzantineValidators 

func (l *LightClientAttackEvidence) GetByzantineValidators(commonVals *ValidatorSet,
	trusted *SignedHeader) []*Validator

GetByzantineValidators finds out what style of attack LightClientAttackEvidence was and then works out who the malicious validators were and returns them. This is used both for forming the ByzantineValidators field and for validating that it is correct. Validators are ordered based on validator power

func (*LightClientAttackEvidence) Hash 

func (l *LightClientAttackEvidence) Hash() []byte

Hash returns the hash of the header and the commonHeight. This is designed to cause hash collisions with evidence that have the same conflicting header and common height but different permutations of validator commit signatures. The reason for this is that we don't want to allow several permutations of the same evidence to be committed on chain. Ideally we commit the header with the most commit signatures (captures the most byzantine validators) but anything greater than 1/3 is sufficient. TODO: We should change the hash to include the commit, header, total voting power, byzantine validators and timestamp

func (*LightClientAttackEvidence) Height 

func (l *LightClientAttackEvidence) Height() int64

Height returns the last height at which the primary provider and witness provider had the same header. We use this as the height of the infraction rather than the actual conflicting header because we know that the malicious validators were bonded at this height which is important for evidence expiry

func (l *LightClientAttackEvidence) String() string

String returns a string representation of LightClientAttackEvidence

func (*LightClientAttackEvidence) Time

	trustedHeader *SignedHeader,
	evidenceTime time.Time,
) error

ValidateABCI validates the ABCI component of the evidence by checking the timestamp, byzantine validators and total voting power all match. ABCI components are validated separately because they can be re generated if invalid.

func (*LightClientAttackEvidence) ValidateBasic 

func (l *LightClientAttackEvidence) ValidateBasic() error

TODO: constraints for Moniker/Other? Or is that for the UI ? JAE: It needs to be done on the client, but to prevent ambiguous unicode characters, maybe it's worth sanitizing it here. In the future we might want to validate these, once we have a name-resolution system up. International clients could then use punycode (or we could use url-encoding), and we just need to be careful with how we handle that in our clients. (e.g. off by default).

Specifically, a proposed block timestamp is considered timely if it is satisfies the following inequalities:

localtime >= proposedBlockTime - Precision localtime <= proposedBlockTime + MsgDelay + Precision

}

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 .VotingPower, so the indices are fixed for all rounds of a given blockchain height - ie. the validators are sorted by their voting power (descending). Secondary index - .Address (ascending).

On the other hand, the .ProposerPriority of each validator and the designated .GetProposer() of a set changes every round, upon calling .IncrementProposerPriority().

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.
