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.
