Introduction

ZK Prover Server

ZK Prover Server provides a REST API for compressing Web Proofs into zero-knowledge proofs (ZKPs):

• POST /compress-web-proof accepts a Web Proof (output of /prove from Web Prover Server or payload from vouch webhook), verifies the Web Proof, parses HTTP transcript and returns a ZK proof,
• POST /verify-zk-proof accepts a ZK proof, public outputs, imageId and verifies the proof.

Example Use Cases

Below are some common use cases of ZK Prover Server:

• Uploading Web Proof on-chain - ZK proof provides succinctness and ease of on-chain verification compared to raw Web Proofs.
• Hiding Web Proof as private input - ZK proof allows you to prove the existence and validity of Web Proof data without revealing the actual Web Proof content.
