This is a pure* typescript version of EIP4844.
You can run the benchmarks using npm run benchmarks.
As a reference point, verifying a KZG proof will take around 57ms with this library.
Internally the library will only throw on bugs, so we return T | Error a lot. At the API level, the library will throw as this is common in libraries.
The API is a bytes array API, so a user should not need to rely on any types defined in this library.
npm install @crate-crypto/crate-4844

let context = new Context()
let blob = ...
let { proof, commitment } = context.computeBlobKZGProf(blob)
let result = context.verifyBlobKZGProof(blob, commitment, proof)
expect(result).to.be.true
