Get zkProof

The zkProof method is designed to retrieve a JSON-formatted proof from Mina Protocol. This proof can be utilized to verify computations or data integrity without revealing sensitive information. The method supports cryptographic rollup steps for compressing multiple computations into a succinct proof.

Method Signature

zkProof(): Promise<TZkProofResponse>;

Syntax

import { ZkDatabase } from 'zkdb';

const zkdb = await ZkDatabase.connect({
  userName: "chiro-user",
  privateKey: "EKFTciRxyxshZjimay9sktsn7v5PvmC5zPq7q4JnitHUytxUVnFP",
  environment: "node",
  // This URL is for test environment
  url: "https://api.zkdatabase.org/graphql",
});

await zkdb.auth.signIn();


console.log(await zkdb.db("zkdb_test").zkProof());

await zkdb.auth.signOut();

Returns

• A promise that resolves to a TZkProofResponse.

The TZkProofResponse contains the following structure:

TZkProofResponse

Property	Type	Description
step	bigint	Represents the rollup step or iteration number within the proof generation.
proof	JsonProof	A JSON object containing the generated zero-knowledge proof.

JsonProof

Field	Type	Description
publicInput	string[]	An array of public inputs used in the proof generation.
publicOutput	string[]	An array of public outputs derived from the proof.
maxProofsVerified	number	The maximum number of proofs verified in the current proof.
proof	string	The encoded proof data in a string format.

Null Case

If no proof is available, the returned promise resolves to null. Ensure to handle this scenario appropriately in your implementation.
