Feature Request: Secure Multi-Party Computation (MPC) as a Service on Zecrey Labs Protocol

[akuon]

Summary: This feature request proposes integrating Secure Multi-Party Computation (MPC) as a service on the Zecrey Labs protocol, allowing users to perform collaborative computations on private data without revealing the underlying information to any individual participant.

Detailed Description:

• Functionality: The proposed service would enable users to upload their private data to the Zecrey Labs protocol and collaboratively perform computations on it while preserving the privacy of the individual data points.
• Technical Implementation: Zecrey Labs' zk-SNARK technology can be leveraged to construct secure circuits representing the desired computations. These circuits would operate on encrypted data, ensuring that only the final results are revealed, not the individual data contributions.
• Benefits:
  • Enhanced privacy: Users can collaborate on sensitive computations without compromising the confidentiality of their data.
  • Increased trust: Enables collaboration between parties who may not inherently trust each other with their private information.
  • New applications: Opens doors for various privacy-preserving applications such as joint financial analysis, collaborative machine learning, and secure voting systems.

Use Cases:

• Financial institutions: Joint credit risk assessments, fraud detection, and portfolio optimization without revealing individual customer data.
• Healthcare providers: Collaborative research on sensitive medical data while maintaining patient privacy.
• Supply chain management: Secure verification of product provenance and tracking sensitive logistics information across multiple parties.
• Government agencies: Secure data analysis for public interest purposes while protecting individual privacy.

Alternative Solutions:

• Trusted third-party (TTP) model: Involves relying on a trusted intermediary to perform the computations on behalf of the participants, which introduces a central point of failure and potential privacy concerns.
• Homomorphic encryption: Allows computations on encrypted data, but can be computationally expensive and limited in functionality compared to MPC.

Additional Context:

• Integration with existing Zecrey Labs tools: The MPC service should be seamlessly integrated with existing Zecrey Labs tools and functionalities for a unified user experience.
• User interface and developer tools: Develop user-friendly interfaces and developer tools to make the MPC service accessible to both technical and non-technical users.
• Standardization and interoperability: Explore collaboration with other blockchain projects to establish standardized protocols for interoperable MPC services across different platforms.

Conclusion:

Integrating Secure Multi-Party Computation as a service on the Zecrey Labs protocol has the potential to revolutionize how individuals and organizations collaborate on sensitive data while preserving privacy. By addressing the technical challenges and ensuring user-friendly interfaces, this feature can unlock new possibilities for secure and efficient data collaboration in various sectors.
