PADO is developing a decentralized credit protocol using the interactive ZK (IZK) technique and Mina zkApp toolkit. The goal is to establish a credit system for Web3 users that addresses the challenges of data authenticity, privacy, and real-world data integration. PADO utilizes state-of-the-art cryptography, including IZK and non-interactive ZK, to create a scalable credit protocol on the Mina ecosystem. The solution involves a PADO-operated IZK node for data attestation, a user-controlled dApp integrated with zkApp for creating credit credentials (CCs) and proofs (CPs), and a comprehensive method outlined in a technical paper (https://eprint.iacr.org/2023/964.pdf). The architecture includes an overview of PADO’s role, the use of zkApp for privacy-related snark proofs, and a detailed workflow for data attestation, user-controlled dApp processing, and transaction verification on Mina.
