Functions ¶

func BallotResult ¶

func BallotResult(
	parentHeader, header *block.Header, parentShardState *shard.State, shardID uint32,
) (shard.SlotList, shard.SlotList, shard.SlotList, error)

BallotResult returns (parentCommittee.Slots, payable, missing, err)

func ComputeAndMutateEPOSStatus ¶ added in v1.3.6

func ComputeAndMutateEPOSStatus(
	bc Reader,
	state *state.DB,
	addr common.Address,
) error

ComputeAndMutateEPOSStatus sets the validator to inactive and thereby keeping it out of consideration in the pool of validators for whenever committee selection happens in future, the signing threshold is 66%

func ComputeCurrentSigning ¶ added in v1.3.4

func ComputeCurrentSigning(
	snapshot, wrapper *staking.ValidatorWrapper,
) *staking.Computed

ComputeCurrentSigning returns (signed, toSign, quotient, error)

func IncrementValidatorSigningCounts ¶

func IncrementValidatorSigningCounts(
	bc Reader,
	staked *shard.StakedSlots,
	state *state.DB,
	signers, missing shard.SlotList,
) error

IncrementValidatorSigningCounts ..

func IsBelowSigningThreshold ¶ added in v1.3.4

func IsBelowSigningThreshold(quotient numeric.Dec) bool

IsBelowSigningThreshold ..

Types ¶

type Reader ¶ added in v1.3.3

type Reader interface {
	ReadValidatorSnapshot(
		addr common.Address,
	) (*staking.ValidatorWrapper, error)
}

Reader ..
