# Welcome!

This is the website of my in-progress book *Proof-of-Work*.

I started this book with many aspirations in mind, but mostly to create a unified reference useful for everyone, from retailers who want to know how to ask the important questions to professional computer scientists looking for a gentle introduction into the world of probabilistic consensus.

But mostly, I want this to be an enjoyable exposition of the beauty of proof-of-work in theory and practice.

**Acknowledgments**:

This book is currently sponsored by [Quai](https://qu.ai/), who generously offered to cover the costs of two weekly workdays while agreeing that I maintain complete creative control.
