In this commit, we update the SignDescriptor struct to instead use the keychain.KeyDescriptor struct inplace of a raw public key. We do this as this allows for a recovery mode, where the caller doesn’t know what key was used exactly, but remembers the precise KeyDescriptor. A stateless signer is still able to re-derive the proper key, as it’s given the full path.
lnwallet
The lnwallet package implements an abstracted wallet controller that is able to drive channel funding workflows, a number of script utilities, witness generation functions for the various Lightning scripts, revocation key derivation, and the commitment update state machine.
The package is used within lnd as the core wallet of the daemon. The wallet
itself is composed of several distinct interfaces that decouple the
implementation of things like signing and blockchain access. This separation
allows new WalletController implementations to be be easily dropped into
lnd without disrupting the code base. A series of integration tests at the
interface level are also in place to ensure conformance of the implementation
with the interface.
