Bitcoin: A Work in Progress—Technical Innovations from the Trenches is a 2022 book by Bitcoin Core contributor Sjors Provoost, with source text maintained openly.

Written by Sjöors Provoost and first published in 2024 by Bitcoin Magazine Books.
Use this book as a route into Bitcoin’s protocol, transactions, scripts, software and engineering trade-offs. Its Atlas links connect the reading to the people, mechanisms and events it discusses.
Primary or authoritative records make these details checkable: Bitcoin: Work in Progress examines Bitcoin as evolving software, monetary infrastructure and social coordination rather than a finished consumer product, linking present trade-offs to development history. They should be verified before using the coordinate in analysis.
The practical limit is: describing an evolving project does not imply arbitrary rules or centralized roadmap control; authorial interpretation, proposed changes and deployed consensus behavior must be kept distinct. A definition, office, chart pattern or published claim is not by itself a prediction or Bitcoin consensus rule.
