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.
Editions follow the naming of Ethereum consensus layer upgrades:
- Edition 0.3: Capella [current WIP]
- Edition 0.2: Bellatrix
- Edition 0.1: Altair
- My original Phase 0 Annotated Specification remains available elsewhere for historical interest.
The latest version is always at https://eth2book.info/latest/. It currently points to the Capella edition. Earlier editions are now frozen as-is, but are of historical interest as the protocol continues to change.
The source material and everything needed to build the site and the PDF 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.
