Constants

const TrustingPeriodFraction = 2

TrustingPeriodFraction is used to compute the IBC clients TrustingPeriod as UnbondingPeriod / TrustingPeriodFraction

Functions

func AccumulateChanges

func AccumulateChanges(currentChanges, newChanges []abci.ValidatorUpdate) []abci.ValidatorUpdate

func ComputeConsumerUnbondingPeriod

func ComputeConsumerUnbondingPeriod(providerUnbondingPeriod time.Duration) time.Duration

ComputeConsumerUnbondingPeriod computes the unbonding period on the consumer from the unbonding period on the provider (providerUnbondingPeriod). In general, the consumer unbonding period should be a bit smaller (e.g., one day) than the provider unbonding period so that it covers the delays of relaying IBC packets. As a result, delegators on the provider would not have to wait longer to unbond their tokens.

func GetChangePubKeyAddress

func GetChangePubKeyAddress(change abci.ValidatorUpdate) (addr []byte)

func OnRecvPacketOnUnknownChannel

func OnRecvPacketOnUnknownChannel(
	ctx sdk.Context,
	scopedKeeper capabilitykeeper.ScopedKeeper,
	channelKeeper ccv.ChannelKeeper,
	packet channeltypes.Packet,
) exported.Acknowledgement

OnRecvPacketOnUnknownChannel handles a received packet that was sent not on an established CCV channel

func SendIBCPacket

func SendIBCPacket(
	ctx sdk.Context,
	scopedKeeper capabilitykeeper.ScopedKeeper,
	channelKeeper ccv.ChannelKeeper,
	channelID string,
	portID string,
	packetData []byte,
) error

SendIBCPacket sends an IBC packet with packetData over the source channelID and portID
