Developing a ZK Validation Module for Supply Chain Industry

Objective:

Develop a ZK validation module for modular smart accounts that ensures   secure, private, and efficient on-chain executions specific to the supply chain industry. This module should utilize Zero-Knowledge proofs to validate operations without revealing sensitive data, thereby   maintaining both privacy and compliance with regulatory requirements.

Key Requirements:

1. Integration with Supply Chain Use Case:

• Design a ZK validation module that integrates with supply chain processes such as product authentication, shipment tracking, and  compliance verification.
• The module should handle verifiable credentials to authenticate entities (like  suppliers, manufacturers, and distributors) without exposing sensitive information.

2. Zero-Knowledge Proof Implementation:

• Implement ZK-proofs to validate supply chain transactions (e.g., proof of origin, proof of delivery) on-chain without revealing underlying details.
• Ensure the ZK-proofs are efficiently generated and verified within   themodular account framework.

3. Modular Account Compatibility:

• The solution must be compatible with ERC 4337 (Account Abstraction Using Alt Mempool) and ERC 7579 (Minimal Modular Smart Accounts)
  standards.
• Utilize ERC 1271 (Standard Signature Validation) for verifying signatures and ERC 165 (Standard Interface Detection) for contract interoperability.

4. Privacy and Security:

• Prioritize privacy by ensuring that the ZK validation module only reveals the necessary proof of operation without exposing additional user or operational data.
• Enhance security by minimizing the attack surface through robust validation logic and cryptographic safeguards.

5. Efficiency and Standardization:

• Optimize the module to reduce on-chain execution costs and enhance the efficiency of smart contract interactions.
• Develop a standardized framework that promotes interoperability across various supply chain dApps and protocols.

Use Case Example: Supply Chain Product Authentication

A supply chain participant (e.g., manufacturer) generates a verifiable credential (VC) that proves the origin of a product batch. Using the ZK validation module, this participant can submit a proof of origin to a decentralized marketplace without revealing the actual product details or supplier information. The module validates the proof on-chain, ensuring the product's authenticity and compliance with industry standards before it is listed for sale.

Expected Deliverables:

• Functional ZK Validation Module: A fully functional module that integrates ZK-proof mechanisms into a modular smart account structure for supply chain use cases.
• Documentation and User Guide: Comprehensive technical documentation, including a user guide for developers to implement the module in their dApps.
• Demonstration: A demo showcasing the module's application in a supply chain scenario, highlighting its privacy, security, and efficiency benefits.
• Interoperability Testing: Evidence of interoperability with existing Ethereum dApps and smart contracts, ensuring broad usability and adoption.
