Functions

func BeaconEntriesForBlock

func BeaconEntriesForBlock(ctx context.Context, bSchedule Schedule, epoch abi.ChainEpoch, parentEpoch abi.ChainEpoch, prev types.BeaconEntry) ([]types.BeaconEntry, error)

func ValidateBlockValues

func ValidateBlockValues(bSchedule Schedule, h *types.BlockHeader, parentEpoch abi.ChainEpoch,
	prevEntry types.BeaconEntry) error

Types

type BeaconPoint

type BeaconPoint struct {
	Start  abi.ChainEpoch
	Beacon RandomBeacon
}

type RandomBeacon

type RandomBeacon interface {
	Entry(context.Context, uint64) <-chan Response
	VerifyEntry(types.BeaconEntry, types.BeaconEntry) error
	MaxBeaconRoundForEpoch(abi.ChainEpoch) uint64
}

RandomBeacon represents a system that provides randomness to Lotus. Other components interrogate the RandomBeacon to acquire randomness that's valid for a specific chain epoch. Also to verify beacon entries that have been posted on chain.

func NewMockBeacon

func NewMockBeacon(interval time.Duration) RandomBeacon

type Response

type Response struct {
	Entry types.BeaconEntry
	Err   error
}

type Schedule

type Schedule []BeaconPoint

func (Schedule) BeaconForEpoch

func (bs Schedule) BeaconForEpoch(e abi.ChainEpoch) RandomBeacon
