Lightning Book of BOLTs

The Lightning Book of BOLTs is a readable compilation of the Lightning Network Specifications. The BOLTs themselves are unchanged. They are grouped here in the order a node actually uses them — connect, open a channel, route a payment, settle on-chain — with short chapter introductions so you know why you’re looking at a given document.

Credit for the protocol belongs to the original BOLT authors. This book is a reading order, not a rewrite.
