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 specifications can be made through pull requests.
Core specifications for Ethereum proof-of-stake clients can be found in specs. These are divided into features. Features are researched and developed in parallel, and then consolidated into sequential upgrades when ready.

Reference tests built from the executable Python spec are available in the Ethereum Proof-of-Stake Consensus Spec Tests repository. Compressed tarballs are available for each release here. Nightly reference tests are available here.

make helpThe following are the broad design goals for the Ethereum proof-of-stake consensus specifications:
- Minimize complexity, even at the cost of some losses in efficiency.
- Remain live through major network partitions and when very large portions of nodes go offline.
- Select components that are quantum secure or easily swappable for quantum-secure alternatives.
- Utilize crypto and design techniques that allow for a large participation of validators.
- Minimize hardware requirements such that a consumer laptop can participate.
