Upgrading Ethereum

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

Aka "The Eth2 Book"

Editions

• Edition 0.1: Altair [WIP]
  • The Altair annotated spec is about done.
  • The chapter on The Incentive Layer is done, pending revision.
  • Parts of the Building Blocks chapter are done, including Shuffling and Simple Serialize. Current WIP is Merkleization.
  • There's a short appendix on how to run the spec.

The plan

My rough (aspirational) plan is as follows:

1. Spend some time fixing typos and polishing the annotated spec.
2. Deliver Edition 1.0: Altair at some point before The Merge (the point at which Ethereum moves to proof of stake). By then, I aim to have done the following:
   • Completed Part 1: Building
   • Completed Part 2: Technical Overview
   • Made a start on Part 4: Future
3. Some while after The Merge, I'll publish a fully revised Edition 2.0: The Merge with all sections complete.
4. Editions 2.5 (with post-Merge clean-ups) and 3.0 (a full revision for sharding) are also in view.

This thing is going to keep me busy for a while 🙂

My old Phase 0 Annotated Spec remains available, but is superseded by this one.
