cynic-1/annotated-spec

Vitalik's annotated eth2 spec. Not intended to be "the" annotated spec; other documents like Ben Edgington's https://benjaminion.xyz/eth2-annotated-spec/ also exist. This one is intended to focus more on design rationale.

Currently the following parts of the spec are available in annotated form:

Phase 0

• The Beacon Chain
• Beacon Chain Fork Choice

Altair (Light client support, validator reward simplifications)

• Changes to the beacon chain
• Light client sync protocol

Bellatrix (Merge)

• Beacon chain changes
• Fork choice (terminal PoW block verification)

Capella (Withdrawals)

• Beacon chain changes (work in progress)

Sharding

• Changes to the beacon chain
