func (*Server) CanonicalHead ¶

func (vs *Server) CanonicalHead(ctx context.Context, req *ptypes.Empty) (*ethpb.BeaconBlock, error)

CanonicalHead of the current beacon chain. This method is requested on-demand by a validator when it is their time to propose or attest.

func (*Server) CommitteeAssignment ¶

func (vs *Server) CommitteeAssignment(ctx context.Context, req *pb.AssignmentRequest) (*pb.AssignmentResponse, error)

CommitteeAssignment returns the committee assignment response from a given validator public key. The committee assignment response contains the following fields for the current and previous epoch:

1.) The list of validators in the committee.
2.) The shard to which the committee is assigned.
3.) The slot at which the committee is assigned.
4.) The bool signaling if the validator is expected to propose a block at the assigned slot.

func (*Server) DomainData ¶

func (vs *Server) DomainData(ctx context.Context, request *pb.DomainRequest) (*pb.DomainResponse, error)

DomainData fetches the current domain version information from the beacon state.

func (*Server) ExitedValidators ¶

func (vs *Server) ExitedValidators(
	ctx context.Context,
	req *pb.ExitedValidatorsRequest) (*pb.ExitedValidatorsResponse, error)

ExitedValidators queries validator statuses for a give list of validators and returns a filtered list of validator keys that are exited.

func (*Server) ValidatorIndex ¶

func (vs *Server) ValidatorIndex(ctx context.Context, req *pb.ValidatorIndexRequest) (*pb.ValidatorIndexResponse, error)

ValidatorIndex is called by a validator to get its index location in the beacon state.

func (*Server) ValidatorPerformance ¶

func (vs *Server) ValidatorPerformance(
	ctx context.Context, req *pb.ValidatorPerformanceRequest,
) (*pb.ValidatorPerformanceResponse, error)

ValidatorPerformance reports the validator's latest balance along with other important metrics on rewards and penalties throughout its lifecycle in the beacon chain.

func (*Server) ValidatorStatus ¶

func (vs *Server) ValidatorStatus(
	ctx context.Context,
	req *pb.ValidatorIndexRequest) (*pb.ValidatorStatusResponse, error)

ValidatorStatus returns the validator status of the current epoch. The status response can be one of the following:

PENDING_ACTIVE - validator is waiting to get activated.
ACTIVE - validator is active.
INITIATED_EXIT - validator has initiated an an exit request.
WITHDRAWABLE - validator's deposit can be withdrawn after lock up period.
EXITED - validator has exited, means the deposit has been withdrawn.
EXITED_SLASHED - validator was forcefully exited due to slashing.

func (*Server) WaitForActivation ¶

func (vs *Server) WaitForActivation(req *pb.ValidatorActivationRequest, stream pb.ValidatorService_WaitForActivationServer) error

WaitForActivation checks if a validator public key exists in the active validator registry of the current beacon state, if not, then it creates a stream which listens for canonical states which contain the validator with the public key as an active validator record.

func (*Server) WaitForChainStart ¶

func (vs *Server) WaitForChainStart(req *ptypes.Empty, stream pb.ValidatorService_WaitForChainStartServer) error

WaitForChainStart queries the logs of the Deposit Contract in order to verify the beacon chain has started its runtime and validators begin their responsibilities. If it has not, it then subscribes to an event stream triggered by the powchain service whenever the ChainStart log does occur in the Deposit Contract on ETH 1.0.
