Only support FIELD_ELEMENTS_PER_BLOB values that are a power of 2. (#249) 
* Intentionally fail to compile with a FIELD_ELEMENTS_PER_BLOB value that is not a power of 2.
We do not want to support or maintain this case, so let us be explicit about it.

* Update src/c_kzg_4844.h

C-KZG-4844

This is a minimal library for EIP-4844 that implements the Polynomial Commitments API. It was originally a stripped-down copy of C-KZG, but it has been heavily modified since then.

Interface functions

There are functions for KZG operations:

  • 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

Bindings

There are bindings for the following languages:

Installation

Initialize the blst submodule:

git submodule update --init

Build the blst library:

cd src
make blst

Build/test the C-KZG-4844 library:

cd src
make
