Overview

Package detection defines a service that reacts to incoming blocks/attestations by running slashing detection for double proposals, double votes, and surround votes according to the eth2 specification. As soon as slashing objects are found, they are sent over a feed for the beaconclient service to submit to a beacon node via gRPC.

	Notifier              beaconclient.Notifier
	SlasherDB             db.Database
	ChainFetcher          beaconclient.ChainFetcher
	BeaconClient          *beaconclient.Service
	AttesterSlashingsFeed *event.Feed
	ProposerSlashingsFeed *event.Feed
}

Config options for the detection service.

type Service

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

Service struct for the detection service of the slasher.

func NewDetectionService

func NewDetectionService(ctx context.Context, cfg *Config) *Service

NewDetectionService instantiation.

func (*Service) DetectAttesterSlashings added in v0.3.8

func (ds *Service) DetectAttesterSlashings(
	ctx context.Context,
	att *ethpb.IndexedAttestation,
) ([]*ethpb.AttesterSlashing, error)

DetectAttesterSlashings detects double, surround and surrounding attestation offences given an attestation.

func (*Service) DetectDoubleProposals added in v0.3.8

func (ds *Service) DetectDoubleProposals(ctx context.Context, incomingBlock *ethpb.SignedBeaconBlockHeader) (*ethpb.ProposerSlashing, error)

DetectDoubleProposals checks if the given signed beacon block is a slashable offense and returns the slashing.

func (*Service) Start

func (ds *Service) Start()

Start the detection service runtime.

func (*Service) Status

func (ds *Service) Status() error

Status returns an error if there exists an error in the notifier service.
