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.

Types ¶
type Config ¶
type Config struct {
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 ¶
NewDetectionService instantiation.
func (*Service) DetectAttesterSlashings ¶
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 ¶
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) UpdateSpans ¶
UpdateSpans passthrough function that updates span maps given an indexed attestation.
