/**
 * @author  PSE & 0xPARC
 * @title   NovaDecider contract, for verifying zk-snarks Nova IVC proofs.
 * @dev     This is an askama template. It will feature a snarkjs groth16 and a kzg10 verifier, from which this contract inherits.
 *          WARNING: This contract is not complete nor finished. It lacks checks to ensure that no soundness issues can happen.
 *          Indeed, we know some of the checks that are missing. And we're working on the solution
 *          but for now, it's good enough for testing and benchmarking.
