Paul Hauner 6a620a31da Fix starting-epoch check in doppelganger (#2491)
## Issue Addressed

NA

## Proposed Changes

Fixes a bug in Doppelganger Protection which would cause false-positives when a VC is restarted in the same epoch where it has already produced a signed message.

It could also cause a false-negative in the scenario where time skips forward (perhaps due to host suspend/wake). The new `time_skips_forward_with_doppelgangers` test covers this case.

This was a simple (and embarrassing, on my behalf) `>=` instead of `<=` bug that was missed by my tests but detected during manual testing by @michaelsproul (🙏). Regression tests have been added.

## Additional Info

NA

## TODO

- [x] Add test for doppelganger in epoch > next_check_epoch

  • Ready for use on Eth2 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 2.0 specification.

Eth2 Deposit Contract

The Lighthouse team acknowledges 0x00000000219ab540356cBB839Cbe05303d7705Fa as the canonical Eth2 deposit contract address.

Documentation

The Lighthouse Book contains information for users and developers.

The Lighthouse team maintains a blog at lighthouse.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.
