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
|
2018-03-11 04:00:57 +01:00
|
|
|
[boltdb](https://github.com/coreos/bbolt), an embedded pure-go key-value store
|
2017-01-11 00:02:30 +01:00
|
|
|
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
