# 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](https://github.com/ethereum/consensus-specs/blob/dev/specs/eip4844/polynomial-commitments.md) API:
|
|
- `bytes_to_bls_field`
|
|
- `vector_lincomb`
|
|
- `g1_lincomb`
|
|
- `blob_to_kzg_commitment`
|
|
- `verify_kzg_proof`
|
|
- `compute_kzg_proof`
|
|
- `evaluate_polynomial_in_evaluation_form`
|
|
|
|
and `compute_powers` from the [Validator](https://github.com/ethereum/consensus-specs/blob/dev/specs/eip4844/validator.md) API.
|
|
|
|
We also provide `load_trusted_setup` and `free_trusted_setup` to load the
|
|
trusted setup data from a file into an object that can be passed to the API
|
|
functions.
|
|
|
|
The only dependency is [blst](https://github.com/supranational/blst).
|
|
Ensure `blst.h` is provided at `../inc` and `libblst.a` at `../lib`.
|
|
(`blst.h` includes `blst_aux.h`, but the latter is unused and can be empty.)
