Standard API

import { Kzg, Blob } from 'tevm';

const blob = Blob.fromData(data);
const commitment = Kzg.Commitment(blob);
const proof = Kzg.Proof(blob, commitment);

console.log(proof.length); // 48
console.log(Blob.Proof.isValid(proof)); // true

Note: Requires c-kzg-4844 library integration (coming soon).

Factory API

ToProof({ computeBlobKzgProof })(blob, commitment): Proof

Tree-shakeable factory pattern with explicit KZG dependency.

Dependencies:

• computeBlobKzgProof: (blob: Uint8Array, commitment: Uint8Array) => Uint8Array - KZG proof function from c-kzg-4844

Example:

import { Kzg } from 'tevm'
import { computeBlobKzgProof } from 'c-kzg'

const Proof = Kzg.ProofFactory({ computeBlobKzgProof })
const proof = Proof(blob, commitment)

Bundle size: KZG crypto only included if you import it explicitly.

Note: Requires c-kzg-4844 library integration (coming soon).
