Similar to what we did for the local state handling, we extract handling all known remote states we can act on (breach, current, pending state) into its own method. Since we want to handle the case where we lost state (both in case of local and remote close) last, we don't rely on the remote state number to check which commit we are looking at, but match on TXIDs directly.
channeldb
The channeldb implements the persistent storage engine for lnd and
generically a data storage layer for the required state within the Lightning
Network. The backing storage engine is
boltdb, an embedded pure-go key-value store
based off of LMDB.
The package implements an object-oriented storage model with queries and mutations flowing through a particular object instance rather than the database itself. The storage implemented by the objects includes: open channels, past commitment revocation states, the channel graph which includes authenticated node and channel announcements, outgoing payments, and invoices
