chainntnfs: send incremental update notifications for tx confirmations
In this commit, we introduce the ability for the different ChainNotifier
implements to send incremental updates to the subscribers of transaction
confirmations. These incremental updates represent how many
confirmations are left for the transaction to be confirmed. They are
sent to the subscriber at every new height of the chain.

Build Status MIT licensed GoDoc

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.
