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

There are functions for loading/freeing the trusted setup:

  • load_trusted_setup
  • load_trusted_setup_file
  • free_trusted_setup

Build & test

To build c_kzg_4844.o, the object file that the bindings use, run make in the src directory. This will ensure the blst submodule has been initialized, build blst, build c_kzg_4844, and run the tests. From the project root, run this:

cd src && make
