dummy()​

static dummy<Input, OutPut>(
   publicInput: Input, 
   publicOutput: OutPut, 
   maxProofsVerified: 0 | 1 | 2, 
domainLog2: number): Promise<Proof<Input, OutPut>>

Dummy proof. This can be useful for ZkPrograms that handle the base case in the same method as the inductive case, using a pattern like this:

method(proof: SelfProof<I, O>, isRecursive: Bool) {
  proof.verifyIf(isRecursive);
  // ...
}

To use such a method in the base case, you need a dummy proof:

let dummy = await MyProof.dummy(publicInput, publicOutput, 1);
await myProgram.myMethod(dummy, Bool(false));

Note: The types of publicInput and publicOutput, as well as the maxProofsVerified parameter, must match your ZkProgram. maxProofsVerified is the maximum number of proofs that any of your methods take as arguments.

• Input

• OutPut

Parameters​

• publicInput: Input

• publicOutput: OutPut

• maxProofsVerified: 0 | 1 | 2

• domainLog2: number= 14
