Functions ¶

func BeaconScheduleFromDrandSchedule ¶ added in v1.25.0

func BeaconScheduleFromDrandSchedule(dcs dtypes.DrandSchedule, genesisTime uint64, ps *pubsub.PubSub) (beacon.Schedule, error)

Types ¶

type DrandBeacon ¶

type DrandBeacon struct {
	// contains filtered or unexported fields
}

DrandBeacon connects Lotus with a drand network in order to provide randomness to the system in a way that's aligned with Filecoin rounds/epochs.

We connect to drand peers via their public HTTP endpoints. The peers are enumerated in the drandServers variable.

The root trust for the Drand chain is configured from build.DrandChain.

func NewDrandBeacon ¶

func NewDrandBeacon(genesisTs, interval uint64, ps *pubsub.PubSub, config dtypes.DrandConfig) (*DrandBeacon, error)

func (*DrandBeacon) Entry ¶

func (db *DrandBeacon) Entry(ctx context.Context, round uint64) <-chan beacon.Response

func (*DrandBeacon) IsChained ¶ added in v1.26.0

func (db *DrandBeacon) IsChained() bool

IsChained tells us whether this particular beacon operates in "chained mode". Prior to Drand quicknet, beacons form a chain. After the introduction of quicknet, they do not, so we need to change how we interact with beacon entries. (See FIP-0063)

func (*DrandBeacon) MaxBeaconRoundForEpoch ¶

func (db *DrandBeacon) MaxBeaconRoundForEpoch(nv network.Version, filEpoch abi.ChainEpoch) uint64

func (*DrandBeacon) VerifyEntry ¶

func (db *DrandBeacon) VerifyEntry(entry types.BeaconEntry, prevEntrySig []byte) error

type DrandHTTPClient ¶ added in v1.1.1

type DrandHTTPClient interface {
	SetUserAgent(string)
}

DrandHTTPClient interface overrides the user agent used by drand
