Functions

func ExportSlashingProtectionJSONCli

func ExportSlashingProtectionJSONCli(cliCtx *cli.Context) error

ExportSlashingProtectionJSONCli extracts a validator's slashing protection history from their database and formats it into an EIP-3076 standard JSON file via a CLI entrypoint to make it easy to migrate machines or Ethereum consensus clients.

Steps: 1. Parse a path to the validator's datadir from the CLI context. 2. Open the validator database. 3. Call the function which actually exports the data from from the validator's db into an EIP standard slashing protection format 4. Format and save the JSON file to a user's specified output directory.

func ImportSlashingProtectionCLI

func ImportSlashingProtectionCLI(cliCtx *cli.Context) error

ImportSlashingProtectionCLI reads an input slashing protection EIP-3076 standard JSON file and attempts to insert its data into our validator DB.

Steps: 1. Parse a path to the validator's datadir from the CLI context. 2. Open the validator database. 3. Read the JSON file from user input. 4. Call the function which actually imports the data from from the standard slashing protection JSON file into our database.

type Service

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

Service represents a service to manage the validator �slashing protection.

func NewService

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

NewService creates a new validator service for the service registry.

func (*Service) CheckAttestationSafety

func (s *Service) CheckAttestationSafety(ctx context.Context, attestation *ethpb.IndexedAttestation) bool

func (*Service) CheckBlockSafety

func (s *Service) CheckBlockSafety(ctx context.Context, blockHeader *ethpb.SignedBeaconBlockHeader) bool

CheckBlockSafety for blocks before submitting them to the node.

func (*Service) Start

func (s *Service) Start()
