Functions

func NewQuerier

func NewQuerier(k Keeper) sdk.Querier

Types

type Keeper

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

    Keeper defines the evidence module's keeper. The keeper is responsible for managing persistence, state transitions and query handling for the evidence module.

    func NewKeeper

    func NewKeeper(
    	cdc *codec.Codec, storeKey sdk.StoreKey, paramSpace params.Subspace,
    	stakingKeeper types.StakingKeeper, slashingKeeper types.SlashingKeeper,
    ) *Keeper

    func (Keeper) GetAllEvidence

    func (k Keeper) GetAllEvidence(ctx sdk.Context) (evidence []exported.Evidence)

      GetAllEvidence returns all stored Evidence objects.

      func (Keeper) GetEvidence

      func (k Keeper) GetEvidence(ctx sdk.Context, hash tmbytes.HexBytes) (evidence exported.Evidence, found bool)

        GetEvidence retrieves Evidence by hash if it exists. If no Evidence exists for the given hash, (nil, false) is returned.

        func (Keeper) GetEvidenceHandler

        func (k Keeper) GetEvidenceHandler(evidenceRoute string) (types.Handler, error)

          GetEvidenceHandler returns a registered Handler for a given Evidence type. If no handler exists, an error is returned.

          func (Keeper) GetParams

          func (k Keeper) GetParams(ctx sdk.Context) (params types.Params)

            GetParams returns the total set of evidence parameters.

            func (Keeper) HandleDoubleSign

            func (k Keeper) HandleDoubleSign(ctx sdk.Context, evidence types.Equivocation)

              HandleDoubleSign implements an equivocation evidence handler. Assuming the evidence is valid, the validator committing the misbehavior will be slashed, jailed and tombstoned. Once tombstoned, the validator will not be able to recover. Note, the evidence contains the block time and height at the time of the equivocation.

              The evidence is considered invalid if: - the evidence is too old - the validator is unbonded or does not exist - the signing info does not exist (will panic) - is already tombstoned

              TODO: Some of the invalid constraints listed above may need to be reconsidered in the case of a lunatic attack.

              func (Keeper) IterateEvidence

              func (k Keeper) IterateEvidence(ctx sdk.Context, cb func(exported.Evidence) bool)

                IterateEvidence provides an interator over all stored Evidence objects. For each Evidence object, cb will be called. If the cb returns true, the iterator will close and stop.

                func (Keeper) Logger

                func (k Keeper) Logger(ctx sdk.Context) log.Logger

                  Logger returns a module-specific logger.

                  func (Keeper) MaxEvidenceAge

                  func (k Keeper) MaxEvidenceAge(ctx sdk.Context) (res time.Duration)

                    MaxEvidenceAge returns the maximum age for submitted evidence.

                    func (Keeper) SetEvidence

                    func (k Keeper) SetEvidence(ctx sdk.Context, evidence exported.Evidence)

                      SetEvidence sets Evidence by hash in the module's KVStore.

                      func (Keeper) SetParams

                      func (k Keeper) SetParams(ctx sdk.Context, params types.Params)

                        SetParams sets the evidence parameters to the param space.

                        func (*Keeper) SetRouter

                        func (k *Keeper) SetRouter(rtr types.Router)

                          SetRouter sets the Evidence Handler router for the x/evidence module. Note, we allow the ability to set the router after the Keeper is constructed as a given Handler may need access the Keeper before being constructed. The router may only be set once and will be sealed if it's not already sealed.

                          func (Keeper) SubmitEvidence

                          func (k Keeper) SubmitEvidence(ctx sdk.Context, evidence exported.Evidence) error

                            SubmitEvidence attempts to match evidence against the keepers router and execute the corresponding registered Evidence Handler. An error is returned if no registered Handler exists or if the Handler fails. Otherwise, the evidence is persisted.
