Decentralized Carbon Credit Marketplace

Overview

This project provides a comprehensive solution to the growing need for transparent, secure, and efficient carbon credit trading. By leveraging blockchain technology, zero-knowledge proofs, and specialized AI agents, we've created a fully decentralized marketplace for carbon credit generation, validation, trading, and offsetting.

• Frontend: Next.js
• Storage: IPFS integration
• ZK-Proof System: Custom implementation (sample proofs available in generated_proofs directory)
• AI Integration: IAgent framework with specialized agent types

DeFi Integration

Our platform incorporates advanced DeFi mechanisms to enhance the carbon market:

• Carbon Credit Borrowing: Organizations can borrow credits against future reduction commitments
• Lending Pools: Carbon-rich entities can lend excess credits at market rates
• Tokenized Carbon Assets: Fractional ownership of carbon projects
• Reputation-Based Credit Scoring: ZK-verified lending eligibility without data exposure
• Automated Repayment Mechanisms: Smart contract enforcement of lending terms
• Cross-Chain Liquidity: Future integration with major DeFi ecosystems

Zero-Knowledge Proof System

Our ZK system enables organizations to verify eligibility without exposing sensitive data:

• Private Inputs: Emissions data, credit history, debt, available tokens
• Circuit Construction: Field element conversion, R1CS constraints
• Proof Generation: SNARK implementation with zero-knowledge property
• On-Chain Verification: Maintains privacy while ensuring compliance
• Sample Proofs: Pre-generated sample proofs available for testing in generated_proofs directory

IAgent System: AI-Powered Experience

• Create multiple Agent: Assists with emissions documentation and also can be deployed on testnet and mainnet correspondingly
• Manage different AI agents: Analyzes market conditions
• Prompt AI agent: Ensures regulatory requirements are met
• Inter-Agent Communication: Agents share information seamlessly

Contract Testing & Interaction

The platform is fully deployed and can be tested using the following commands:

Unit Testing

To run unit tests for the smart contracts, navigate to the /contracts/src/ directory and execute the following command:

cargo test

This will run all the unit tests defined in the smart contract code, ensuring that the logic and functionality are working as expected.
