Upgrading Ethereum

A technical handbook on Ethereum's move to proof of stake and beyond

Aka "The Eth2 Book".

This is a work in progress. It is not a small project, and will take some time to complete. I appreciate your patience.


The latest version is always at https://eth2book.info/latest. It currently points to the Bellatrix edition.

The source material is available on GitHub.


Kind souls sometimes ask for a way to send me a cup of coffee or make a donation. My account info is below - donations are absolutely not expected or necessary, but are always very encouraging and gratefully received.

Any whales or large treasuries out there, I encourage you to take a look at the Protocol Guild which supports the people developing and maintaining our incredible technology, not just writing about it.
