To learn more about sharding and Ethereum 2.0 (Serenity), see the [sharding FAQ](https://github.com/ethereum/wiki/wiki/Sharding-FAQ) and the [research compendium](https://notes.ethereum.org/s/H1PGqDhpm).
|
|
|
|
This repository hosts the current Eth 2.0 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
|
|
|
|
Core specifications for Eth 2.0 client validation can be found in [specs/core](specs/core). These are divided into phases. Each subsequent phase depends upon the prior. The current phases specified are:
|
|
|
|
### Phase 0
|
|
* [The Beacon Chain](specs/core/0_beacon-chain.md)
|
|
* [Fork Choice](specs/core/0_fork-choice.md)
|
|
* [Deposit Contract](specs/core/0_deposit-contract.md)
|
|
* [Honest Validator](specs/validator/0_beacon-chain-validator.md)
|
|
|
|
### Phase 1
|
|
* [Custody Game](specs/core/1_custody-game.md)
|
|
* [Shard Data Chains](specs/core/1_shard-data-chains.md)
|
|
|
|
### Accompanying documents can be found in [specs](specs) and include:
|
|
|
|
* [SimpleSerialize (SSZ) spec](specs/simple-serialize.md)
|
|
* [BLS signature verification](specs/bls_signature.md)
|
|
* [General test format](specs/test_formats/README.md)
|
|
* [Merkle proof formats](specs/light_client/merkle_proofs.md)
|
|
* [Light client syncing protocol](specs/light_client/sync_protocol.md)
|
|
* [Beacon node API for validator](specs/validator/0_beacon-node-validator-api.md)
|
|
|
|
|
|
## Design goals
|
|
|
|
The following are the broad design goals for Ethereum 2.0:
|
|
* to minimize complexity, even at the cost of some losses in efficiency
|
|
* to remain live through major network partitions and when very large portions of nodes go offline
|
|
* to select all components such that they are either quantum secure or can be easily swapped out for quantum secure counterparts when available
|
|
* to utilize crypto and design techniques that allow for a large participation of validators in total and per unit time
|
|
* to allow for a typical consumer laptop with `O(C)` resources to process/validate `O(1)` shards (including any system level validation such as the beacon chain)
|
|
|
|
|
|
## For spec contributors
|
|
|
|
Documentation on the different components used during spec writing can be found here:
|
|
* [YAML Test Generators](test_generators/README.md)
|
|
* [Executable Python Spec, with Py-tests](test_libs/pyspec/README.md)
