const (
	// The default concentration of bonded tokens a validator is allowed as a multiple of equal shares
	DefaultConcentrationMultiple = 5.5 // Amounts to ~8% with 68 validators
	// Maximum Allowed Cap for Bonded stake of any single validator
	DefaultMaxCapPercent = 0.33
	// Minimum Allowed Cap for Bonded stake of any single validator
	DefaultMinCapPercent = 0.05

var DefaultRestrictionOptions = &RestrictionOptions{
	MaxConcentrationMultiple: DefaultConcentrationMultiple,
	MaxBondedCapPercent:      DefaultMaxCapPercent,
	MinBondedCapPercent:      DefaultMinCapPercent,
}

DefaultRestrictionOptions are default constraints that prevent single point of failure on validators

var UnlimitedRestrictionOptions = &RestrictionOptions{
	MaxConcentrationMultiple: 1.0,
	MaxBondedCapPercent:      1.0,
	MinBondedCapPercent:      1.0,
}

UnlimitedRestrictionOptions are used to remove restrictions for validator staking limits from delegations

Functions ¶

func AggregateEvents ¶ added in v1.13.0

func AggregateEvents(anteEvents []abci.Event, resultEvents []abci.Event) ([]abci.Event, []abci.Event)

AggregateEvents is called in the baseapp after a transaction has completed This is used to modify the events that are emitted for a transaction. anteEvents will be populated on failure and success resultEvents will only be populated on success

func NewAdditionalMsgFeeHandler ¶

func NewAdditionalMsgFeeHandler(options PioBaseAppKeeperOptions) (sdk.FeeHandler, error)

Types ¶

type MsgFeeInvoker ¶

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

func NewMsgFeeInvoker ¶

func NewMsgFeeInvoker(bankKeeper bankkeeper.Keeper, accountKeeper msgfeestypes.AccountKeeper,
	feegrantKeeper msgfeestypes.FeegrantKeeper, msgFeeKeeper msgfeestypes.MsgFeesKeeper, decoder sdk.TxDecoder) MsgFeeInvoker

NewMsgFeeInvoker concrete impl of how to charge Msg Based Fees

func (MsgFeeInvoker) Invoke ¶

func (afd MsgFeeInvoker) Invoke(ctx sdk.Context, _ bool) (sdk.Coins, sdk.Events, error)

type MsgServiceHandler ¶

type MsgServiceHandler = func(ctx sdk.Context, req sdk.Msg) (*sdk.Result, error)

MsgServiceHandler defines a function type which handles Msg service message.

type PioBaseAppKeeperOptions ¶

type PioBaseAppKeeperOptions struct {
	AccountKeeper  msgfeestypes.AccountKeeper
	BankKeeper     bankkeeper.Keeper
	FeegrantKeeper msgfeestypes.FeegrantKeeper
	MsgFeesKeeper  msgfeestypes.MsgFeesKeeper
	Decoder        sdk.TxDecoder
}

type PioMsgServiceRouter ¶

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

PioMsgServiceRouter routes fully-qualified Msg service methods to their handler with additional fee processing of msgs.

func NewPioMsgServiceRouter ¶

func NewPioMsgServiceRouter(decoder sdk.TxDecoder) *PioMsgServiceRouter

NewPioMsgServiceRouter creates a new PioMsgServiceRouter.

func (*PioMsgServiceRouter) Handler ¶

func (msr *PioMsgServiceRouter) Handler(msg sdk.Msg) MsgServiceHandler

Handler returns the MsgServiceHandler for a given msg or nil if not found.

func (*PioMsgServiceRouter) HandlerByTypeURL ¶

func (msr *PioMsgServiceRouter) HandlerByTypeURL(typeURL string) MsgServiceHandler

HandlerByTypeURL returns the MsgServiceHandler for a given query route path or nil if not found.

func (*PioMsgServiceRouter) RegisterService ¶

func (msr *PioMsgServiceRouter) RegisterService(sd *grpc.ServiceDesc, handler interface{})

RegisterService implements the gRPC Server.RegisterService method. sd is a gRPC service description, handler is an object which implements that gRPC service.

This function PANICs:

if it is called before the service `Msg`s have been registered using RegisterInterfaces,
or if a service is being registered twice.

func (*PioMsgServiceRouter) SetCircuit ¶ added in v1.16.0

func (msr *PioMsgServiceRouter) SetCircuit(cb baseapp.CircuitBreaker)

func (*PioMsgServiceRouter) SetInterfaceRegistry ¶

func (msr *PioMsgServiceRouter) SetInterfaceRegistry(interfaceRegistry codectypes.InterfaceRegistry)

SetInterfaceRegistry sets the interface registry for the router.

func (*PioMsgServiceRouter) SetMsgFeesKeeper ¶

func (msr *PioMsgServiceRouter) SetMsgFeesKeeper(msgFeesKeeper msgfeeskeeper.Keeper)

SetMsgFeesKeeper sets the msg based fee keeper for retrieving msg fees.

type RestrictionOptions ¶ added in v1.14.0

type RestrictionOptions struct {
	MaxConcentrationMultiple float32
	MaxBondedCapPercent      float32
	MinBondedCapPercent      float32
}

type StakingRestrictionHooks ¶ added in v1.14.0

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

Hooks wrapper struct for slashing keeper

func NewStakingRestrictionHooks ¶ added in v1.14.0

func NewStakingRestrictionHooks(k *stakingkeeper.Keeper, opts RestrictionOptions) StakingRestrictionHooks

NewStakingRestrictionHooks configures a hook that validates changes to delegation modifications and prevents concentration of voting power beyond configured limits on active validators.

func (StakingRestrictionHooks) AfterDelegationModified ¶ added in v1.14.0

func (h StakingRestrictionHooks) AfterDelegationModified(ctx sdktypes.Context, _ sdktypes.AccAddress, valAddr sdktypes.ValAddress) error

Verifies that the delegation would not cause the validator's voting power to exceed our staking distribution limits
