This is an implementation of a slasher that lives inside the BN and can be enabled via `lighthouse bn --slasher`. Features included in this PR: - [x] Detection of attester slashing conditions (double votes, surrounds existing, surrounded by existing) - [x] Integration into Lighthouse's attestation verification flow - [x] Detection of proposer slashing conditions - [x] Extraction of attestations from blocks as they are verified - [x] Compression of chunks - [x] Configurable history length - [x] Pruning of old attestations and blocks - [x] More tests Future work: * Focus on a slice of history separate from the most recent N epochs (e.g. epochs `current - K` to `current - M`) * Run out-of-process * Ingest attestations from the chain without a resync Design notes are here https://hackmd.io/@sproul/HJSEklmPL |

Lighthouse: Ethereum 2.0
An open-source Ethereum 2.0 client, written in Rust and maintained by Sigma Prime.
🚨🚨🚨 Note: Lighthouse is not yet ready to produce mainnet deposits. The developers will require some time to test against the mainnet deposit contract, once it is released. DO NOT SUBMIT VALIDATOR DEPOSITS WITH LIGHTHOUSE. 🚨🚨🚨
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 Ethereum 2.0 specification.
Like all Ethereum 2.0 clients, Lighthouse is a work-in-progress.
Eth2 Deposit Contract
The Lighthouse team acknowledges
0x00000000219ab540356cBB839Cbe05303d7705Fa
as the canonical Eth2 deposit contract address.
Development Status
Current development overview:
- Specification
v1.0.0implemented, 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
