C-KZG-4844: A minimal library for EIP-4844 Polynomial Commitments

This is a copy of C-KZG stripped-down to support the Polynomial Commitments API:

  • blob_to_kzg_commitment
  • compute_kzg_proof
  • verify_kzg_proof
  • compute_blob_kzg_proof
  • verify_blob_kzg_proof
  • verify_blob_kzg_proof_batch

We also provide functions for loading/freeing the trusted setup:

  • load_trusted_setup
  • load_trusted_setup_file
  • free_trusted_setup

Installation

Initialize the blst submodule:

git submodule update --init

Build blst:

cd src
make blst

Build the C-KZG code:

cd src
make
