Methods

declare()

declare(): boolean;

Defined in: lib/proof-system/proof.ts:54

To verify a recursive proof inside a ZkProgram method, it has to be "declared" as part of the method. This is done by calling declare() on the proof.

Note: declare() is a low-level method that most users will not have to call directly. For proofs that are inputs to the ZkProgram, it is done automatically.

You can think of declaring a proof as a similar step as witnessing a variable, which introduces that variable to the circuit. Declaring a proof will tell Pickles to add the additional constraints for recursive proof verification.

Similar to Provable.witness(), declare() is a no-op when run outside ZkProgram compilation or proving. It returns false in that case, and true if the proof was actually declared.

Returns

boolean

ProofBase.declare

verify()

verify(): void;

Defined in: lib/proof-system/proof.ts:132

Sets the shouldVerify flag to true The downstream effect of this is that the proof will be verified when the circuit is run

Returns

void

Note

This method is meant to be called in a circuit. Executing it outside of a circuit will have no effect.


verifyIf()

verifyIf(condition: Bool): void;

Defined in: lib/proof-system/proof.ts:142

Sets the shouldVerify flag to the given condition param If set to Bool(true), the proof will be verified when the circuit is run If set to Bool(false), the proof will not be verified when the circuit is run

Parameters

condition

Bool

Returns

void

Note

This method is meant to be called in a circuit. Executing it outside of a circuit will have no effect.

dummy()

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

Defined in: lib/proof-system/proof.ts:182

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.
