Server defines a server implementation of the gRPC Validator service, providing RPC endpoints intended for validator clients.

func (*Server) GetAggregateAttestation 

func (vs *Server) GetAggregateAttestation(ctx context.Context, req *ethpbv1.AggregateAttestationRequest) (*ethpbv1.AggregateAttestationResponse, error)

GetAggregateAttestation aggregates all attestations matching the given attestation data root and slot, returning the aggregated result.

func (*Server) GetAttesterDuties 

func (vs *Server) GetAttesterDuties(ctx context.Context, req *ethpbv1.AttesterDutiesRequest) (*ethpbv1.AttesterDutiesResponse, error)

GetAttesterDuties requests the beacon node to provide a set of attestation duties, which should be performed by validators, for a particular epoch.

func (*Server) GetProposerDuties 

func (vs *Server) GetProposerDuties(ctx context.Context, req *ethpbv1.ProposerDutiesRequest) (*ethpbv1.ProposerDutiesResponse, error)

GetProposerDuties requests beacon node to provide all validators that are scheduled to propose a block in the given epoch.

func (*Server) GetSyncCommitteeDuties 

func (vs *Server) GetSyncCommitteeDuties(ctx context.Context, req *ethpbv2.SyncCommitteeDutiesRequest) (*ethpbv2.SyncCommitteeDutiesResponse, error)

GetSyncCommitteeDuties provides a set of sync committee duties for a particular epoch.

The logic for calculating epoch validity comes from https://ethereum.github.io/beacon-APIs/?urls.primaryName=dev#/Validator/getSyncCommitteeDuties where `epoch` is described as `epoch // EPOCHS_PER_SYNC_COMMITTEE_PERIOD <= current_epoch // EPOCHS_PER_SYNC_COMMITTEE_PERIOD + 1`.

Algorithm:

  • Get the last valid epoch. This is the last epoch of the next sync committee period.
  • Get the state for the requested epoch. If it's a future epoch from the current sync committee period or an epoch from the next sync committee period, then get the current state.
  • Get the state's current sync committee. If it's an epoch from the next sync committee period, then get the next sync committee.
  • Get duties.

func (*Server) PrepareBeaconProposer 

func (vs *Server) PrepareBeaconProposer(
	ctx context.Context, request *ethpbv1.PrepareBeaconProposerRequest,
) (*emptypb.Empty, error)

PrepareBeaconProposer caches and updates the fee recipient for the given proposer.

func (*Server) ProduceAttestationData 

func (vs *Server) ProduceAttestationData(ctx context.Context, req *ethpbv1.ProduceAttestationDataRequest) (*ethpbv1.ProduceAttestationDataResponse, error)

ProduceAttestationData requests that the beacon node produces attestation data for the requested committee index and slot based on the nodes current head.

func (*Server) ProduceBlindedBlock 

func (vs *Server) ProduceBlindedBlock(ctx context.Context, req *ethpbv1.ProduceBlockRequest) (*ethpbv2.ProduceBlindedBlockResponse, error)

ProduceBlindedBlock requests the beacon node to produce a valid unsigned blinded beacon block, which can then be signed by a proposer and submitted.

Pre-Bellatrix, this endpoint will return a regular block.

func (*Server) ProduceBlindedBlockSSZ 

func (vs *Server) ProduceBlindedBlockSSZ(ctx context.Context, req *ethpbv1.ProduceBlockRequest) (*ethpbv2.SSZContainer, error)

ProduceBlindedBlockSSZ requests the beacon node to produce a valid unsigned blinded beacon block, which can then be signed by a proposer and submitted.

The produced block is in SSZ form.

Pre-Bellatrix, this endpoint will return a regular block.

func (*Server) ProduceBlockV2 

func (vs *Server) ProduceBlockV2(ctx context.Context, req *ethpbv1.ProduceBlockRequest) (*ethpbv2.ProduceBlockResponseV2, error)

ProduceBlockV2 requests the beacon node to produce a valid unsigned beacon block, which can then be signed by a proposer and submitted.

func (*Server) ProduceBlockV2SSZ 

func (vs *Server) ProduceBlockV2SSZ(ctx context.Context, req *ethpbv1.ProduceBlockRequest) (*ethpbv2.SSZContainer, error)

ProduceBlockV2SSZ requests the beacon node to produce a valid unsigned beacon block, which can then be signed by a proposer and submitted.

The produced block is in SSZ form.

func (*Server) ProduceSyncCommitteeContribution 

func (vs *Server) ProduceSyncCommitteeContribution(
	ctx context.Context,
	req *ethpbv2.ProduceSyncCommitteeContributionRequest,
) (*ethpbv2.ProduceSyncCommitteeContributionResponse, error)

ProduceSyncCommitteeContribution requests that the beacon node produce a sync committee contribution.

func (*Server) SubmitAggregateAndProofs 

func (vs *Server) SubmitAggregateAndProofs(ctx context.Context, req *ethpbv1.SubmitAggregateAndProofsRequest) (*empty.Empty, error)

SubmitAggregateAndProofs verifies given aggregate and proofs and publishes them on appropriate gossipsub topic.

func (*Server) SubmitBeaconCommitteeSubscription 

func (vs *Server) SubmitBeaconCommitteeSubscription(ctx context.Context, req *ethpbv1.SubmitBeaconCommitteeSubscriptionsRequest) (*emptypb.Empty, error)

SubmitBeaconCommitteeSubscription searches using discv5 for peers related to the provided subnet information and replaces current peers with those ones if necessary.

func (*Server) SubmitContributionAndProofs 

func (vs *Server) SubmitContributionAndProofs(ctx context.Context, req *ethpbv2.SubmitContributionAndProofsRequest) (*empty.Empty, error)

SubmitContributionAndProofs publishes multiple signed sync committee contribution and proofs.

func (*Server) SubmitSyncCommitteeSubscription 

func (vs *Server) SubmitSyncCommitteeSubscription(ctx context.Context, req *ethpbv2.SubmitSyncCommitteeSubscriptionsRequest) (*empty.Empty, error)

SubmitSyncCommitteeSubscription subscribe to a number of sync committee subnets.

Subscribing to sync committee subnets is an action performed by VC to enable network participation in Altair networks, and only required if the VC has an active validator in an active sync committee.

func (*Server) SubmitValidatorRegistration 

func (vs *Server) SubmitValidatorRegistration(ctx context.Context, reg *ethpbv1.SubmitValidatorRegistrationsRequest) (*empty.Empty, error)

SubmitValidatorRegistration submits validator registrations.
