Add payload attestation helper functions #14258

jihoonsong · 2024-07-24T07:36:14Z

What type of PR is this?
This PR adds three payload attestation helper functions and their unit tests: get_payload_attesting_indices, get_indexed_payload_attestation, and is_valid_indexed_payload_attestation.

IndexedPayloadAttestation doesn't have to be a protobuf; it can be a native Go type. We only define something as a protobuf when we need SSZ functionality, like hash tree roots, but IndexedPayloadAttestation doesn't require consensus.

This is the wrong domain

Good catch, thank you

Hi @jihoonsong, there's only one function pending for helpers get_attesting_indices, can you include that as well? It only requires small modification, Did you miss to include it?

jihoonsong · 2024-07-25T07:38:15Z

This PR is for those three functions as described.

+	validators := make([]*ethpb.Validator, validatorCount)
+	_, secretKeys, err := util.DeterministicDepositsAndKeys(validatorCount)
+	require.NoError(t, err)


Do we need this number of validators to test the Indexed payload attestation? This takes a long time ~30s on my laptop which is lengthy fo ra unit test

It's a really good point! Modified it to create 350 validators. Can be reduced further if needed.

This is too expensive, please get the read only validator for each index without copying them all

Thank you for pointing it out, modified it.

This still allocates about a million pointers when you can have a maximum of 512 signatures in the attestation.
