This is useful when we wish to have a channel frozen for a specific amount of blocks after its confirmation. This could also be done with an absolute thaw height, but it does not suit cases where a strict block delta needs to be enforced, as it's not possible to know for certain when a channel will be included in the chain. To work around this, we add a relative interpretation of the field, where if its value is below 500,000, then it's interpreted as a relative height. This approach allows us to prevent further database modifications to account for a relative thaw height.
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
