chainntnfs ========== [![Build Status](http://img.shields.io/travis/lightningnetwork/lnd.svg)] (https://travis-ci.org/lightningnetwork/lnd) [![MIT licensed](https://img.shields.io/badge/license-MIT-blue.svg)] [![GoDoc](https://img.shields.io/badge/godoc-reference-blue.svg)] (http://godoc.org/github.com/lightningnetwork/lnd/chainntnfs) 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`. ## Installation and Updating ```bash $ go get -u github.com/lightningnetwork/lnd/chainntnfs ```
