In this commit, we update all the key derivation within the state machine to account for the recent spec change which introduces a distinct key for usages within all HTLC scripts. This change means that the commitment payment and delay base points, are only required to be online in the case that a party is forced to go to chain. We introduce an additional local tweak to the keyring for the HTLC tweak. Additionally, two new keys have been added: a local and a remote HTLC key. Generation of sender/receiver HTLC scripts now use the local and remote HTLC keys rather than the “payment” key for each party. Finally, when creating/verifying signatures for second-level HTLC transactions, we use these the distinct HTLC keys, rather than re-using the payment keys. |

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.
