I would call it EquivocationChecker and add a thorough comment. Eq sounds like equals in other programming languages

Better change the Godoc for SubmitBlockSSZ then.

In our usual block processing pipeline we verify the block time disparity at this stage. Do we need to do it here?

are nil checks for blk.Block() necessary?

This case literally can't happen.

Can you do this before the defer function?

I am setting up a testnet and I would insanely appreciate a Dockerfile in order to set this up in Docker. Would it be possible to get a hold of one? |

Is this PR still required when using the latest version of prysm used by the relays? |

hi @dewindtk check out https://github.com/OffchainLabs/eth-pos-devnet if you want to set up a testnet. If you want to test out a specific change, such as this PR, you will need to build images with Bazel here: https://docs.prylabs.network/docs/install/install-with-bazel#running-images. We do not use dockerfiles |
Before broadcast, this PR applies consensus and equivocation checks for the beacon API's propose block endpoint.
