ALEPH 2024 Hackaton MVP - Zama Track

Confidential public procurement processes evaluator system MVP

This repo contains the documentation and code for the MVP of the Confidential public procurement processes evaluator system.

MVP

This MVP will be focused on a specifically on "Open competitive bidding (or tendering)" method without the ZKP handling on the bidding process

Public procurement sample will focused on a process evaluating two criterias: 1. Cuantitative: The smaller price. 2. Compliance: Has demostrable experience in similar projects in the past? (yes/no)

System Desing

Using this will show how the system will work with more complex processes and more criterias.

Architecture

dApp: Interacts with bidders, Requesters, and the blockchain. Smart Contract: Handles the procurement process, evaluation rules, and bid data. Zero-Knowledge Proof (ZKP): Ensures bid data is encrypted correctly and using the latest version of the dApp. Fully Homomorphic Encryption (FHE): Protects sensitive data during evaluation. Wallet: Used by bidders for authentication and bid submission. Requesters: Interact with the system to create, test, and approve the procurement process. System Administrators: Monitor and configure the system.

Smart Contract & ZKP Generation Flow

The smart contract and ZKP generation work during the bidding process, including the following steps:

Procurement Process Creation: Requesters input data, and the system generates a smart contract automatically. Bidder Submission: Bidders submit encrypted data, and ZKPs are generated to ensure the submission is valid and encrypted correctly. Evaluation: The smart contract evaluates encrypted bids based on the predefined rules. Result Query: Bidders query the results, which are encrypted, and the dApp decrypts and presents the outcome.

Long-term Implementation Steps

Step 1: Set up the dApp framework (frontend & backend).

Step 2: Integrate with ZAMA FHEvm to handle encryption and smart contract generation.

Step 3: Implement the smart contract generation logic using ZAMA Solidity Developer GPT.

Step 4: Develop bid submission logic with wallet integration and ZKP generation.

Step 5: Build the evaluation logic in the smart contract.

Step 6: Deploy the smart contract and enable bidder interaction.

Step 7: Implement the auditability layer using the immutable nature of the smart contract and ZKP verification.

Step 8: Build and run test suit.

MVP Implementation

Step 1: Set up the dApp framework (frontend & backend).

Step 2: Integrate with ZAMA FHEvm to handle encryption and smart contract generation.

Step 3: Develop bid submission logic with wallet integration.

Step 4: Build the evaluation logic in the smart contract for the proposed MVP sample.

Step 5: Deploy the smart contract and enable bidder interaction.

Step 6: Build and run test suit.
