Paul Hauner 2de26b20f8 Don't return errors on HTTP API for already-known messages (#3341)
## Issue Addressed

- Resolves #3266

## Proposed Changes

Return 200 OK rather than an error when a block, attestation or sync message is already known.

Presently, we will log return an error which causes a BN to go "offline" from the VCs perspective which causes the fallback mechanism to do work to try and avoid and upcheck offline nodes. This can be observed as instability in the `vc_beacon_nodes_available_count` metric.

The current behaviour also causes scary logs for the user. There's nothing to *actually* be concerned about when we see duplicate messages, this can happen on fallback systems (see code comments).

  • 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.
