Michael Sproul cc4b778b1f Inline safe_arith methods (#3229)
## Proposed Changes

Speed up epoch processing by around 10% by inlining methods from the `safe_arith` crate.

The Rust standard library uses `#[inline]` for the `checked_` functions that we're wrapping, so it makes sense for us to inline them too.

## Additional Info

I conducted a brief statistical test on the block at slot [3858336](https://beaconcha.in/block/3858336) applied to the state at slot 3858335, which requires an epoch transition. The command used for testing was:

```
lcli transition-blocks --testnet-dir ./common/eth2_network_config/built_in_network_configs/mainnet --no-signature-verification state.ssz block.ssz output.ssz
``` 

The testing found that inlining reduced the epoch transition time from 398ms to 359ms, a reduction of 9.77%, which was found to be statistically significant with a two-tailed t-test (p < 0.01).

Overview

Lighthouse is:

  • Ready for use on Ethereum consensus mainnet.
  • Fully open-source, licensed under Apache 2.0.
  • Security-focused. Fuzzing techniques have been continuously applied and several external security reviews have been performed.
  • 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, the Decentralization Foundation and private individuals.
  • Actively involved in the specification and security analysis of the Ethereum proof-of-stake consensus specification.

Staking Deposit Contract

The Lighthouse team acknowledges 0x00000000219ab540356cBB839Cbe05303d7705Fa as the canonical staking deposit contract address.

Documentation

The Lighthouse Book contains information for users and developers.

The Lighthouse team maintains a blog at lighthouse-blog.sigmaprime.io which contains periodical progress updates, roadmap insights and interesting findings.

Branches

Lighthouse maintains two permanent branches:

  • stable: Always points to the latest stable release.
    • This is ideal for most users.
  • unstable: Used for development, contains the latest PRs.
    • Developers should base their PRs on this branch.

Contributing

Lighthouse welcomes contributors.
