Paul Hauner 8772c02fa0 Reduce temp allocations in network metrics (#1895) 
## Issue Addressed

Using `heaptrack` I could see that ~75% of Lighthouse temporary allocations are caused by temporary string allocations here.

## Proposed Changes

Reduces temporary `String` allocations when updating metrics in the `network` crate. The solution isn't perfect since we rebuild our caches with each call, but it's a significant improvement.

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 v1.0.0 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.
  • Q4 2020: Long-lived, multi-client Beacon Chain testnet
  • Q4 2020: Additional third-party security reviews.
  • Q4 2020: Production Beacon Chain (tentative).
