This PR specifies the changes to the Fork Choice specification required for the safe execution of the confirmation rule specified in #3339.

By implementing these changes, the confirmation rule can be safely run by means of beacon APIs calls, though there would be no connection to the execution layer.

See sections 3.1 to 3.4 of this document for the rationale about the changes proposed and the related security analysis.

TODO:

  • Fix tests
  • Add changes to Bellatrix fork choice spec.

The change looks good to me. I don't think Bellatrix FC is affected by the change introduce in this PR. A question, would we need to add new tests along fixing the existing ones? (I guess no but asking just in case)

I'm not sure I follow -- is this to pull out a bit of functionality into specifically defined functions so that the beacon-api's can just reference these functions instead of trying to (re)define the behaviour there?

I'm not sure I understand the connection to the Beacon-APIs here. can you elaborate?

This PR includes the changes to the Fork Choice required to ensure the safety of the confirmation rule.

This means that, once this PR is implemented, the confirmation rule can be safely executed via standard Beacon API calls as done here.

I have updated the title and PR description accordingly.

I hope that this clarifies.

This looks good/correct.

Need to port to non-Phase0 functions as needed and then we can merge

Just checked and it looks like that no change is required to any of the non-Phase 0 specs.

We just need to confirm the test fix with @adiasg and @mkalinin
(Currently ongoing)

The PR itself looks good to me. 👍

But since it's a substantive change, we may need to be clear about when it can be on devnet/testnet/mainnet before merging it.
