Types

type ChannelInfo

type ChannelInfo struct {
	// Version is the version of the channel backup. This uniquely
	// identifies the type of channel we're working with.
	Version chanbackup.SingleBackupVersion

	// LocalNodeKey is the node's identifying public key.
	LocalNodeKey *btcec.PublicKey

	// RemoteNodeKey is the remote node's identifying public key.
	RemoteNodeKey *btcec.PublicKey

	// LocalPaymentBasePoint is the node's base public key used within the
	// non-delayed pay-to-self output on the commitment transaction.
	LocalPaymentBasePoint *btcec.PublicKey

	// RemotePaymentBasePoint is the remote node's base public key used
	// within the non-delayed pay-to-self output on the commitment
	// transaction.
	RemotePaymentBasePoint *btcec.PublicKey
}

ChannelInfo contains the relevant info required for a third-party to detect a channel lifetime violation by either party. These are obtained individually from the channel backup of each channel participant.

func GatherChannelInfo

func GatherChannelInfo(ctx context.Context, client lndclient.LightningClient,
	wallet lndclient.WalletKitClient,
	channelPoint wire.OutPoint) (*ChannelInfo, error)

GatherChannelInfo retrieves the relevant channel info from a channel's participant point of view required for the auctioneer to enforce channel lifetime violations.

func (*ChannelInfo) Match

func (a *ChannelInfo) Match(b *ChannelInfo) error

Matches determines whether a pair of ChannelInfo correspond to each other. This serves as a helper function to ensure channel participants provide the auctioneer with the correct expected keys.
