Decentralized Carbon Credit Marketplace

ZK-Proofs & Mainnet Deployment for Climate Finance Transparency

---

Executive Summary

We have built a fully decentralized carbon credit marketplace deployed on mainnet, leveraging zero-knowledge proofs (ZKPs) for privacy and ERC20 tokens for carbon asset representation. Our platform addresses the trust, transparency, and efficiency gaps in traditional carbon markets — enabling secure, private, and verifiable climate action at scale.

The Climate Crisis Demands Bold Infrastructure

• Global CO₂ emissions hit 36.8 billion tonnes in 2023 (IEA, 2024)

• IPCC: We have <7 years to drastically reduce emissions (Sixth Assessment Report)

• Carbon markets projected to exceed $100B by 2030, but plagued by:

  • Greenwashing
  • Weak verification standards
  • Privacy barriers
  • Market fragmentation

Our Competitive Edge: Fully Decentralized & Mainnet-Deployed

MAINNET DEPLOYED — No testnet. No simulations. This is live infrastructure.

• Verifier Contract:

  0xA31a0b24369bb899D557Cb8cc0411b3336778f3f

• CarbonCredit ERC20 Token:

  0x04f083E9925Ad711045Aa896f8022FED9C402a93

• Marketplace Contract:

  0xAb0992eaD847B28904c8014E770E0294Cd198866

ZKPs: Privacy Without Compromise

We utilize SNARKJS + Circom circuits to integrate on-chain zero-knowledge proofs that protect organizational data without sacrificing transparency or verifiability.

Why ZKPs Matter:

• Hide emissions data while proving compliance

• Maintain financial & operational privacy

• Prevent reputational risks

• Ensure trustless verification of:

  • Credit eligibility
  • Credit repayments
  • Borrowing history
  • Emissions reduction

Our ZK circuits are stored on-chain — enabling permissionless, decentralized verification with zero data leakage.

---

ERC20 Tokenization: Liquidity & Interoperability

• Carbon credits are issued as ERC20 tokens, making them:

  • Fungible
  • Composable with DeFi
  • Easily tradeable on DEXs
  • Auditable on-chain

---

User Profiles & Reputation Scoring

Each organization on the platform maintains an evolving, ZK-protected profile:

string profilePhotoipfsHashCode;
address walletAddress;
uint256 timesBorrowed;
uint256 timesLent;
uint256 totalCarbonCreditsLent;
uint256 totalCarbonCreditsBorrowed;
uint256 totalCarbonCreditsReturned;
uint256 emissions;
uint256 reputationScore;

This structure powers a reputation-based credit mechanism, where ZKPs are used to validate behavior without revealing raw data — enabling trustless loans, reputation staking, and compliance scoring.

---

💱 Integrated DeFi Layer for Carbon Finance

• Borrowing: Use future emissions reductions as collateral
• Lending Pools: Entities with surplus credits earn yield
• Tokenized Projects: Invest in fractional climate impact
• Reputation-Backed Loans: No overcollateralization needed
• ZK-Enforced Repayments: Privacy-respecting loan cycles

🛠️ Smart Contract Interaction & Testing

Sample command to verify ZK-protected carbon claim:

# Submit proof + credit claim
carbonMarketplace.submitCarbonClaim(
  proof,
  publicSignals,
  tokenAmount,
  ipfsHash
);
