v2.0.0

This is a major release which adds support for EIP-7594 (PeerDAS).

Notable changes:

• The codebase implements and exposes all public methods of the EIP-7594 cryptography specification.
• The trusted setup format has been updated to include G1 points in monomial form.
  • This version of c-kzg-4844 requires the new trusted setup file.
  • The new trusted setup file can be used with previous versions of c-kzg-4844.
  • Download the new file from trusted_setup.txt in this repository.
  • This should match trusted_setup_4096.json in the specifications.
• A new precompute parameter has been added to functions which load the trusted setup.
  • This configuration option is used to optimize FK20 proof computations.
  • Higher values will compute FK20 proofs faster but use more memory.
  • Compared to precompute=0, precompute=8 is ~75% faster but uses 96 MiB of memory.
• In the Nim bindings, the "zero overhead aliases" have been removed.
  • There is only a single set of API functions exposed now.
• In the Rust bindings, the API functions have been moved to the KzgSettings structure.
  • For example, here is the before and after for blob_to_kzg_commitment:
    • KZGCommitment::blob_to_kzg_commitment(&blob, &kzg_settings)
    • kzg_settings.blob_to_kzg_commitment(&blob)
