func RegisterRandomnessServer(s *grpc.Server, srv RandomnessServer)

Types

type BeaconClient 

type BeaconClient interface {
	NewBeacon(ctx context.Context, in *BeaconRequest, opts ...grpc.CallOption) (*BeaconResponse, error)
}

func NewBeaconClient 

func NewBeaconClient(cc *grpc.ClientConn) BeaconClient

type BeaconRequest 

type BeaconRequest struct {
	Round        uint64 `protobuf:"varint,1,opt,name=round" json:"round,omitempty"`
	PreviousRand []byte `protobuf:"bytes,2,opt,name=previous_rand,json=previousRand,proto3" json:"previous_rand,omitempty"`
	PartialRand  []byte `protobuf:"bytes,3,opt,name=partial_rand,json=partialRand,proto3" json:"partial_rand,omitempty"`
}

BeaconRequest holds a link to a previous signature, a timestamp and the partial signature for this beacon. All participants send and collects many of theses partial beacon packets to recreate locally one beacon

	Randomness   []byte `protobuf:"bytes,3,opt,name=randomness,proto3" json:"randomness,omitempty"`
}

PublicRandResponse holds a signature which is the random value. It can be verified thanks to the distributed public key of the nodes that have ran the DKG protocol and is unbiasable. The randomness can be verified using the BLS verification routine with the message "round || previous_rand".
