Please describe your proposed solution

zkFiat is unique because it harmonizes regulatory compliance with user privacy without centralizing user data. By ensuring that only users hold all their personal information, we eliminate single points of failure and reduce the risk of data breaches. We are already working with a European bank, which demonstrates the practical applicability and effectiveness of our solution in real-world financial systems. Our solution leverages zero-knowledge proofs within the Cardano blockchain, making it a pioneering approach in privacy-preserving compliance.

Described Solution

zkFiat introduces a decentralized mechanism where only the user holds all necessary information for compliance. No single entity has complete access to user data, preserving privacy while ensuring compliance.

• User:
• Receives a KYC proof from the bank.
• Obtains a unique User ID from the bank.
• Receives a Bank ID from Gero.
• Holds all the information securely.
• Wallet:
• Does not have access to KYC information and cannot verify the proof.
• Receives the User ID from the bank.
• Generates a Bank ID corresponding to the User ID.
• Bank:
• Holds KYC information securely.
• Cannot verify the proof independently.
• Does not know that the User ID and Bank ID are related.

If the user is verified, the transaction is created and can then be signed by the user. This decentralized knowledge approach keeps information secure and private, enabling seamless, compliant transactions without revealing personal data to the bank.

This architecture ensures:

• Enhanced Privacy: Users comply with regulations without disclosing personal information.

• Regulatory Compliance: Financial institutions process transactions confidently, meeting compliance standards without handling sensitive data.

• Decentralization: Eliminates single points of failure or data breaches.

Please define the positive impact your project will have on the wider Cardano community

Prototype Development and Testing: Creating a functional prototype that showcases the effectiveness of zkFiat in real-world scenarios.

User Adoption Metrics: Tracking the number of users and transactions processed using zkFiat.

Partnerships with Financial Institutions: Establishing collaborations to validate the practicality and compliance of our solution.
