The chainntnfs package implements a set of interfaces which allow callers to
|
|
receive notifications in response to specific on-chain events. The set of
|
|
notifications available include:
|
|
|
|
* Notifications for each new block connected to the current best chain.
|
|
* Notifications once a `txid` has reached a specified number of
|
|
confirmations.
|
|
* Notifications once a target outpoint (`txid:index`) has been spent.
|
|
|
|
These notifications are used within `lnd` in order to properly handle the
|
|
workflows for: channel funding, cooperative channel closures, forced channel
|
|
closures, channel contract breaches, sweeping time-locked outputs, and finally
|
|
pruning the channel graph.
|
|
|
|
This package is intentionally general enough to be applicable outside the
|
|
specific use cases within `lnd` outlined above. The current sole concrete
|
|
implementation of the `ChainNotifier` interface depends on `btcd`.
