Minimal sample

// load the library once at startup
CKZG4844JNI.loadNativeLibrary();

// once a trusted setup is loaded, all methods will use it
CKZG4844JNI.loadTrustedSetup("trusted-setup.txt");

byte[] blob = ...;
byte[] commitment = CKZG4844JNI.blobToKzgCommitment(blob);
byte[] proof = CKZG4844JNI.computeBlobKzgProof(blob, commitment);

boolean isValidProof = CKZG4844JNI.verifyBlobKzgProof(blob, commitment, proof);

// the current trusted setup should be freed before a new one is loaded
CKZG4844JNI.freeTrustedSetup();

Loading trusted setup

There are two ways to load the trusted setup.

File

The file needs to be of the following format: trusted_setup.txt

Method parameters

Look at the loadTrustedSetup(byte[], long, byte[], long) method.
