This commit introduce a new struct which acts as a companion struct to the channel state machine struct. With the new commitment state machine, we require a signature to be signed and validated for each outstanding non-trimmed HTLC within the commitment state. As it’s possible to have hundreds of HTLC’s on a given commitment transaction, rather than perform all ECDSA operations in serial, we instead aim to parallelize the computation with a worker pool of sign+verify workers. The two primary methods of the sigPool are SubmitVerifyBatch and SubmitSignBatch which allow a caller to trigger an asynchronous job execution when creating or validating a new commitment state.
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.
