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(network.Version, 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
