Secure Multi-Party Computation (SMPC) for Avail

Summary: Implement Secure Multi-Party Computation (SMPC) functionality within the Avail project to enable secure and private computations on confidential data across multiple parties without revealing the underlying data itself.

Detailed Description:

SMPC is a cryptographic technique that allows multiple parties to jointly compute a function on their private inputs without disclosing those inputs to each other or to any third party. This offers significant advantages in blockchain applications, particularly for Avail's focus on decentralized finance (DeFi).

Use Cases:

• Private Credit Scoring: Financial institutions can collaborate to assess a borrower's creditworthiness without revealing individual credit details, protecting user privacy and reducing fraud risks.
• Joint Risk Assessment: Insurance companies can share and analyze risk data for specific events (e.g., natural disasters) while keeping individual policyholder information confidential.
• Secure Market Analysis: Investment firms can collaborate on market analysis and generate insights without disclosing their individual trading positions.
• Fraud Detection: Consortiums of financial institutions can combine data for fraud detection without revealing sensitive customer information.

Alternative Solutions:

• Homomorphic Encryption (HE): While HE allows computations on encrypted data, it is computationally expensive and might not be suitable for real-world DeFi applications.
• Trusted Execution Environments (TEEs): TEEs provide a secure enclave within a processor for computations, but they introduce a centralized element that might contradict Avail's decentralized philosophy.

Alternative Context:

• Privacy-Preserving DeFi: SMPC integration strengthens Avail's position in privacy-focused DeFi, attracting users who value control over their financial data.
• Regulatory Compliance: SMPC can help Avail comply with evolving data privacy regulations like GDPR and CCPA by enabling secure collaboration without compromising user privacy.

Benefits of Implementing SMPC:

• Enhanced User Privacy: Users retain control over their data while participating in DeFi activities.
• Increased Security: SMPC mitigates risks associated with data breaches and unauthorized access.
• Improved Collaboration: Enables secure data sharing and collaboration between different parties in the DeFi ecosystem.
• Scalability: SMPC solutions are constantly evolving to handle increasing data volumes and transaction rates.

Next Steps:

• Conduct a feasibility study to evaluate the technical challenges and potential integration methods for SMPC within Avail.
• Engage with the Avail community to gather feedback and assess user demand for this feature.
• Explore collaborations with existing SMPC protocol developers for efficient integration.

By implementing SMPC functionality, Avail can position itself as a leader in privacy-preserving DeFi, fostering a secure and collaborative financial ecosystem.

Avail DA is just a data availability platform and does not infer data. The above should be implemented inside rollups and not DA layer.
