In this commit, we start to thread thru the new aux tap leaf structures to all relevant areas. This includes: commitment outputs, resolution creation, breach handling, and also HTLC scripts. Given the aux leaf store, and a struct that describes the current commitment, we can obtain the CommitAuxLeaves struct, then use that to derive the aux leaves for the commitment outputs and also HTLCs as well. When restoring commitments and pay descs from disk, we'll store the aux leaves as custom TLV blobs on disk, then use the aux leaf store to map back to the concrete aux leaves when needed.
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 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.
