KZG Point Evaluation Test Vectors

This directory contains test vectors for the KZG point evaluation algorithm that are loaded and used throughout different tests.

Each file must contain a JSON list of objects, each with the following fields:

• name: a string describing the test case
• input: object containing commitment, proof, z and y
• output: expected output of the evaluation, true, false or null.

Generating The Test Vectors (used in v1.0.6 and on)

From execution-spec-tests release v1.0.6 and on, the point evaluation test vectors were generated using commit 63aa303c from the official-kzg consensus-specs branch.

The test vectors were generated as following:

1. In the consensus-specs repo:

   cd tests/generators/kzg_4844/
   rm -rf /tmp/kzg_4844_output
   mkdir /tmp/kzg_4844_output
   python -m main --output /tmp/kzg_4844_output
   

2. In the execution-spec-tests repo:

   cd tests/cancun/4844_blobs/point_evaluation_vectors/
   pip install -r requirements.txt
   python concat_kzg_vectors_to_json.py \
       --input /tmp/kzg_4844_output/general/deneb/kzg/verify_kzg_proof/kzg-mainnet/
       --output go_kzg_4844_verify_kzg_proof.json
   

Previous Versions of the Test Vectors (used up to v1.0.5)

The test vectors up and including execution-spec-tests release v1.0.5 were: - go_kzg_4844_verify_kzg_proof.json: test vectors from the go-kzg-4844 repository.
