Types

type AggregateAndProofService 

type AggregateAndProofService Service[*SignedAggregateAndProofForGossip]

func NewAggregateAndProofService 

func NewAggregateAndProofService(
	ctx context.Context,
	syncedDataManager *synced_data.SyncedDataManager,
	forkchoiceStore forkchoice.ForkChoiceStorage,
	beaconCfg *clparams.BeaconChainConfig,
	opPool pool.OperationsPool,
	test bool,
	batchSignatureVerifier *BatchSignatureVerifier,
) AggregateAndProofService

type AggregateVerificationData 

type AggregateVerificationData struct {
	Signatures  [][]byte
	SignRoots   [][]byte
	Pks         [][]byte
	F           func()
	SendingPeer *sentinel.Peer
}

each AggregateVerification request has sentinel.SentinelClient and *sentinel.GossipData to make sure that we can validate it separately and in case of failure we ban corresponding GossipData.Peer or simply run F and publish GossipData in case signature verification succeeds.

func GetSignaturesOnAggregate 

func GetSignaturesOnAggregate(
	s *state.CachingBeaconState,
	aggregateAndProof *cltypes.SignedAggregateAndProof,
	attestingIndicies []uint64,
) (*AggregateVerificationData, error)

type AttestationForGossip 

type AttestationForGossip struct {
	Attestation       *solid.Attestation
	SingleAttestation *solid.SingleAttestation // New container after Electra
	Receiver          *sentinel.Peer
	// ImmediateProcess indicates whether the attestation should be processed immediately or able to be scheduled for later processing.

}

AttestationWithGossipData type represents attestation with the gossip data where it's coming from.

type AttestationService

type BlobSidecarsService 

type BlobSidecarsService Service[*cltypes.BlobSidecar]

func NewBlobSidecarService 

func NewBlobSidecarService(
	ctx context.Context,
	beaconCfg *clparams.BeaconChainConfig,
	forkchoiceStore forkchoice.ForkChoiceStorage,
	syncedDataManager *synced_data.SyncedDataManager,
	ethClock eth_clock.EthereumClock,

type ProposerSlashingService Service[*cltypes.ProposerSlashing]

type Service 

type Service[T any] interface {
	ProcessMessage(ctx context.Context, subnet *uint64, msg T) error
}

func NewBlockService 

func NewBlockService(

type SignedAggregateAndProofForGossip 

type SignedAggregateAndProofForGossip struct {
	SignedAggregateAndProof *cltypes.SignedAggregateAndProof
	Receiver                *sentinel.Peer
	ImmediateProcess        bool
}

SignedAggregateAndProofData is passed to SignedAggregateAndProof service. The service does the signature verification asynchronously. That's why we cannot wait for its ProcessMessage call to finish to check error. The service will do re-publishing of the gossip or banning the peer in case of invalid signature by itself. that's why we are passing sentinel.SentinelClient and *sentinel.GossipData to enable the service to do all of that by itself.

type SignedBLSToExecutionChangeForGossip 

type SignedBLSToExecutionChangeForGossip struct {
	SignedBLSToExecutionChange *cltypes.SignedBLSToExecutionChange
	Receiver                   *sentinel.Peer
	ImmediateVerification      bool
}

SignedBLSToExecutionChangeForGossip type represents SignedBLSToExecutionChange with the gossip data where it's coming from.

type SignedContributionAndProofForGossip 

type SignedContributionAndProofForGossip struct {
	SignedContributionAndProof *cltypes.SignedContributionAndProof
	Receiver                   *sentinel.Peer
	ImmediateVerification      bool
}

SignedContributionAndProofWithGossipData type represents SignedContributionAndProof with the gossip data where it's coming from.

type SignedVoluntaryExitForGossip 

type SignedVoluntaryExitForGossip struct {
	SignedVoluntaryExit   *cltypes.SignedVoluntaryExit
	Receiver              *sentinel.Peer
	ImmediateVerification bool
