func (Keeper) DeserializeValidatorIterator added in v0.7.0 

func (k Keeper) DeserializeValidatorIterator(vals []byte) stakingtypes.ValAddresses

DeserializeValidatorIterator returns validators from the validator iterator. Adding here in gravity keeper as cdc is not available inside endblocker.

func (Keeper) GetAttestationByNonce added in v0.7.0 

func (k Keeper) GetAttestationByNonce(ctx sdk.Context, nonce uint64) (types.AttestationRequestI, bool, error)

func (Keeper) GetCurrentDataCommitment added in v0.7.0 

func (k Keeper) GetCurrentDataCommitment(ctx sdk.Context) (types.DataCommitment, error)

func (Keeper) GetLastUnBondingBlockHeight added in v0.7.0 

func (k Keeper) GetLastUnBondingBlockHeight(ctx sdk.Context) uint64

GetLastUnBondingBlockHeight returns the last unbonding block height or zero if not set. This value is not saved or loaded at genesis. This value is reset to zero on chain upgrade.

func (Keeper) GetLastValsetBeforeNonce added in v0.7.0 

func (k Keeper) GetLastValsetBeforeNonce(ctx sdk.Context, nonce uint64) (*types.Valset, error)

GetLastValsetBeforeNonce returns the previous valset before the provided `nonce`. the `nonce` can be a valset, but this method will return the valset before it. If the provided nonce is 1, it will return an error, because, there is no valset before nonce 1.

func (Keeper) GetLatestAttestationNonce added in v0.7.0 

func (k Keeper) GetLatestAttestationNonce(ctx sdk.Context) uint64

GetLatestAttestationNonce returns the latest attestation request nonce. Panics if the latest attestation nonce doesn't exit. Make sure to call `CheckLatestAttestationNonce` before getting the nonce. This value is set on chain startup, it shouldn't panic in normal conditions. Check x/qgb/genesis.go for more information.

func (Keeper) GetLatestValset added in v0.7.0 

func (k Keeper) GetLatestValset(ctx sdk.Context) (*types.Valset, error)

GetLatestValset returns the latest validator set in store. This is different from the CurrentValset because this one has been saved and is therefore *the* latest valset saved in store. GetCurrentValset shows you what could be, if you chose to save it, this function shows you what is the latest valset that was saved. Panics if no valset is found. Because, a valset is always created when starting the chain. Check x/qgb/abci.go:68 for more information.

Create new gravity hooks

func (Keeper) LastUnbondingHeight added in v0.7.0

	c context.Context,
	req *types.QueryLastValsetRequestBeforeNonceRequest,
) (*types.QueryLastValsetRequestBeforeNonceResponse, error)

LastValsetRequestBeforeNonce queries the last valset request before nonce

func (Keeper) LatestAttestationNonce added in v0.7.0 

func (k Keeper) LatestAttestationNonce(
	ctx context.Context,
	request *types.QueryLatestAttestationNonceRequest,

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

func (Keeper) Params added in v0.7.0 

func (k Keeper) Params(c context.Context, request *types.QueryParamsRequest) (*types.QueryParamsResponse, error)

func (Keeper) SetAttestationRequest added in v0.7.0 

func (k Keeper) SetAttestationRequest(ctx sdk.Context, at types.AttestationRequestI) error

SetAttestationRequest sets a new attestation request to the store to be signed by orchestrators afterwards.

func (Keeper) SetLastUnBondingBlockHeight added in v0.7.0 

func (k Keeper) SetLastUnBondingBlockHeight(ctx sdk.Context, unbondingBlockHeight uint64)

SetLastUnBondingBlockHeight sets the last unbonding block height. Note this value is not saved to state or loaded at genesis. This value is reset to zero on chain upgrade.

func (Keeper) SetLatestAttestationNonce added in v0.7.0 

func (k Keeper) SetLatestAttestationNonce(ctx sdk.Context, nonce uint64)

SetLatestAttestationNonce sets the latest attestation request nonce, since it's expected that this value will only increase by one and it panics otherwise.

func (Keeper) SetParams added in v0.7.0 

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

SetParams sets the parameters in the store

func (Keeper) StoreAttestation added in v0.7.0 

func (k Keeper) StoreAttestation(ctx sdk.Context, at types.AttestationRequestI)

StoreAttestation saves the attestation in store. Should panic if overwriting existing one.

type StakingKeeper added in v0.7.0 

type StakingKeeper interface {
	GetValidator(ctx sdk.Context, addr sdk.ValAddress) (validator stakingtypes.Validator, found bool)
	GetBondedValidatorsByPower(ctx sdk.Context) []stakingtypes.Validator
	GetLastValidatorPower(ctx sdk.Context, valAddr sdk.ValAddress) int64
	GetParams(ctx sdk.Context) stakingtypes.Params
	ValidatorQueueIterator(ctx sdk.Context, endTime time.Time, endHeight int64) sdk.Iterator
	GetValidatorByEVMAddress(ctx sdk.Context, addr common.Address) (validator stakingtypes.Validator, found bool)
}

StakingKeeper restricts the functionality of the bank keeper used in the qgb keeper
