Intro

This guide is specific to getting LND 0.5-beta and Bitcoind running on Ubuntu 16.04 LTS for mainnet. It is aging rapidly and includes steps not necessary on newer versions of LND. As of April 2021 it is very out of date for bitcoind. As of December 2021 it is outdated for LND too.

Original installation guide:

https://github.com/lightningnetwork/lnd/blob/master/docs/INSTALL.md

This guide is broken into the following sections:

Install bitcoind and set to start automatically
Install development tools and dependancies

LND backup script for `channel.backup` using inotify

Install inotify

sudo apt install inotify-tools

Create script to watch for changes and copy on change

Blockchain Rule Update Process

We recently rolled out two changes to the Bitcoin block acceptance rules (BIP16 and BIP30); this document records the lessons learned and makes recommendations for handling future blockchain rule changes.

Note: there are "soft" rule changes and "hard" rule changes. "Soft" changes tighten up the rules-- old software will accept all the blocks and transactions created by new software, but the opposite may not be true. "Soft" changes do not require the entire network of miners and merchants and users to upgrade or be left behind.

"Hard" changes modify the rules in a way that old, un-upgraded software consider illegal. At this point it is much, much more difficult (some might say impossible) to roll out "hard" changes, because they require every miner and merchant and user to upgrade.
