This repository hosts the current Ethereum proof-of-stake specifications. Discussions about design rationale and proposed changes can be brought up and discussed as issues. Solidified, agreed-upon changes to the spec can be made through pull requests.


## Specs

[![GitHub release](https://img.shields.io/github/v/release/ethereum/eth2.0-specs)](https://github.com/ethereum/eth2.0-specs/releases/) [![PyPI version](https://badge.fury.io/py/eth2spec.svg)](https://badge.fury.io/py/eth2spec)

Core specifications for Ethereum proof-of-stake clients can be found in [specs](specs/). These are divided into features.
Features are researched and developed in parallel, and then consolidated into sequential upgrades when ready.

The current features are:

### Phase 0

* [The Beacon Chain](specs/phase0/beacon-chain.md)
* [Beacon Chain Fork Choice](specs/phase0/fork-choice.md)
* [Deposit Contract](specs/phase0/deposit-contract.md)
* [Honest Validator](specs/phase0/validator.md)
* [P2P Networking](specs/phase0/p2p-interface.md)
* [Weak Subjectivity](specs/phase0/weak-subjectivity.md)

### Altair

* [Beacon chain changes](specs/altair/beacon-chain.md)
* [Altair fork](specs/altair/fork.md)
* [Light client sync protocol](specs/altair/sync-protocol.md)
* [Honest Validator guide changes](specs/altair/validator.md)
* [P2P Networking](specs/altair/p2p-interface.md)

### Bellatrix (also known as The Merge)

The Bellatrix protocol upgrade is still actively in development. The exact specification has not been formally accepted as final and details are still subject to change.

* Background material:
* An [ethresear.ch](https://ethresear.ch) post [describing the basic mechanism of the CL+EL merge](https://ethresear.ch/t/the-eth1-eth2-transition/6265)
* [ethereum.org](https://ethereum.org) high-level description of the CL+EL merge [here](https://ethereum.org/en/eth2/docking/)
* Specifications:
* [Beacon Chain changes](specs/bellatrix/beacon-chain.md)
* [Bellatrix fork](specs/bellatrix/fork.md)
* [Fork Choice changes](specs/bellatrix/fork-choice.md)
* [Validator additions](specs/bellatrix/validator.md)
* [P2P Networking](specs/bellatrix/p2p-interface.md)

### Sharding

Sharding follows Bellatrix, and is divided into three parts:

* Sharding base functionality - In early engineering phase
* [Beacon Chain changes](specs/sharding/beacon-chain.md)
* [P2P Network changes](specs/sharding/p2p-interface.md)
* Custody Game - Ready, dependent on sharding
* [Beacon Chain changes](specs/custody_game/beacon-chain.md)
* [Validator custody work](specs/custody_game/validator.md)
* Data Availability Sampling - In active R&D
* Technical details [here](https://hackmd.io/@HWeNw8hNRimMm2m2GH56Cw/B1YJPGkpD).
* [Core types and functions](specs/das/das-core.md)
* [P2P Networking](specs/das/p2p-interface.md)
* [Fork Choice](specs/das/fork-choice.md)
* [Sampling process](specs/das/sampling.md)
