Ethereum consensus client in Rust
1d278aaa83
## Issue Addressed Implements support for importing and exporting the slashing protection DB interchange format described here: https://hackmd.io/@sproul/Bk0Y0qdGD Also closes #1584 ## Proposed Changes * [x] Support for serializing and deserializing the format * [x] Support for importing and exporting Lighthouse's database * [x] CLI commands to invoke import and export * [x] Export to minimal format (required when a minimal format has been previously imported) * [x] Tests for export to minimal (utilising mixed importing and attestation signing?) * [x] Tests for import/export of complete format, and import of minimal format * [x] ~~Prevent attestations with sources less than our max source (Danny's suggestion). Required for the fake attestation that we put in for the minimal format to block attestations from source 0.~~ * [x] Add the concept of a "low watermark" for compatibility with the minimal format Bonus! * [x] A fix to a potentially nasty bug involving validators getting re-registered each time the validator client ran! Thankfully, the ordering of keys meant that the validator IDs used for attestations and blocks remained stable -- otherwise we could have had some slashings on our hands! 😱 * [x] Tests to confirm that this bug is indeed vanquished |

Lighthouse: Ethereum 2.0
An open-source Ethereum 2.0 client, written in Rust and maintained by Sigma Prime.
Overview
Lighthouse is:
- Fully open-source, licensed under Apache 2.0.
- Security-focused. Fuzzing has begun and security reviews are underway.
- Built in Rust, a modern language providing unique safety guarantees and excellent performance (comparable to C++).
- Funded by various organisations, including Sigma Prime, the Ethereum Foundation, ConsenSys and private individuals.
- Actively involved in the specification and security analysis of the emerging Ethereum 2.0 specification.
Like all Ethereum 2.0 clients, Lighthouse is a work-in-progress.
Development Status
Current development overview:
- Specification
v0.12.3implemented, optimized and passing test vectors. - Rust-native libp2p with Gossipsub and Discv5.
- RESTful JSON API via HTTP server.
- Events via WebSocket.
- Metrics via Prometheus.
Roadmap
April 2019: Inital single-client testnets.September 2019: Inter-operability with other Ethereum 2.0 clients.Q1 2020:lighthouse-0.1.0release: All major phase 0 features implemented.Q2 2020: Public, multi-client testnet with user-facing functionality.Q2 2020: Third-party security review.- Q3 2020: Additional third-party security reviews.
- Q3 2020: Long-lived, multi-client Beacon Chain testnet
- Q4 2020: Production Beacon Chain (tentative).
