Paul Hauner 21bcc8848d Add caching for state.eth1_data_votes (#919)
## Issue Addressed

NA

## Proposed Changes

Adds additional tree hash caching for `state.eth1_data_votes`.

Presently, each time we tree hash the `BeaconState`, we recompute the `state.eth1_data_votes` tree in it's entirety. This is because we only previous had support for caching fixed-length lists.

This PR adds the `Eth1DataVotesTreeHashCache` which provides caching for the `state.eth1_data_votes` list. The cache is aware of `SLOTS_PER_ETH1_VOTING_PERIOD` and will reset itself whenever that boundary is crossed.

This cache adds a new (but somewhat fundamental) restriction to tree hash caching:

*For some state `s`, `s.tree_hash_cache` is only valid for `s` or descendants of `s` that have been reached via state transitions that are faithful to the specification (invalid blocks are permitted, as long as they are faithfully processed).*

Overview

Lighthouse is:

  • Fully open-source, licensed under Apache 2.0.
  • Security-focused. Fuzzing has begun and security reviews are planned for late-2019.
  • 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 v0.12.1 implemented, 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-0.1.0 release: 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).

Documentation

The Lighthouse Book contains information for testnet users and developers.

Code documentation is generated via cargo doc and hosted at lighthouse-docs.sigmaprime.io.
