In this commit, we remove references to raw keys from the main ChannelConfig struct and instead replace it with usage of keychain.KeyDescriptor. We do this, as the ChannelConfig as it stands is a near complete static description of a channel. In the future, it will be possible to export these static descriptions as backups. We prefer the KeyDescriptor of a plain PublicKey, as the KeyLocator portion of the struct allows a stateless signer to re-derive the keys as needed when signing.
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
