This commit updates the set of functions tasked with generating HTLC’s scripts for new commitments to now adhere to the new commitment transaction design. With this change, the process of claiming an HTLC now requires a second-level HTLC transaction, which solves a prior issues due to the tight coupling of the timeout and delay clauses when claiming an HTLC.
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.
