Documentation

Overview

Package rpc defines an implementation of a gRPC slasher service, providing endpoints for determining whether or not a block/attestation is slashable based on slasher's evidence.

Types

type Config

type Config struct {
	Host         string
	Port         string
	CertFlag     string
	KeyFlag      string
	Detector     *detection.Service
	SlasherDB    db.Database
	BeaconClient *beaconclient.Service
}

Config options for the slasher node RPC server.

type Server

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

Server defines a server implementation of the gRPC Slasher service, providing RPC endpoints for retrieving slashing proofs for malicious validators.

func (*Server) HighestAttestations

func (ss *Server) HighestAttestations(ctx context.Context, req *slashpb.HighestAttestationRequest) (*slashpb.HighestAttestationResponse, error)

HighestAttestations returns the highest observed attestation source and epoch for a given validator id.

func (*Server) IsSlashableAttestation

func (ss *Server) IsSlashableAttestation(ctx context.Context, req *ethpb.IndexedAttestation) (*slashpb.AttesterSlashingResponse, error)

IsSlashableAttestation returns an attester slashing if the attestation submitted is a slashable vote.

func (*Server) IsSlashableAttestationNoUpdate

func (ss *Server) IsSlashableAttestationNoUpdate(ctx context.Context, req *ethpb.IndexedAttestation) (*slashpb.Slashable, error)

IsSlashableAttestationNoUpdate returns true if the attestation submitted is a slashable vote (no db update is being done).

func (*Server) IsSlashableBlock

func (ss *Server) IsSlashableBlock(ctx context.Context, req *ethpb.SignedBeaconBlockHeader) (*slashpb.ProposerSlashingResponse, error)

IsSlashableBlock returns an proposer slashing if the block submitted is a double proposal.

func (*Server) IsSlashableBlockNoUpdate

func (ss *Server) IsSlashableBlockNoUpdate(ctx context.Context, req *ethpb.BeaconBlockHeader) (*slashpb.Slashable, error)

IsSlashableBlockNoUpdate returns true if the block submitted is slashable (no db update is being done).

type Service

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

Service defines a server implementation of the gRPC Slasher service, providing RPC endpoints for retrieving slashing proofs for malicious validators.

func NewService

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

NewService instantiates a new RPC service instance that will be registered into a running beacon node.

func (*Service) Start

func (s *Service) Start()

Start the gRPC service.

func (*Service) Status

func (s *Service) Status() error

Status returns nil if slasher is ready to receive attestations and blocks from clients for slashing detection.

func (*Service) Stop

func (s *Service) Stop() error

Stop the service.
