Project Description

CarbonSeal – Web3 Carbon Footprint Oracle CarbonSeal is an AI-powered blockchain application designed to bring transparent and verifiable carbon footprint tracking to Web3. Built for the EthGlobal Agentic Hackathon, CarbonSeal estimates the carbon emissions of Ethereum transactions using machine learning and verifies carbon offsetting via Brevis ZK proofs on EigenLayer. By integrating AI, Zero-Knowledge (ZK) technology, and blockchain, CarbonSeal provides an immutable proof of an Ethereum wallet or smart contract’s carbon neutrality.

How CarbonSeal Works CarbonSeal operates in three key phases:

1️⃣ AI-Powered Carbon Footprint Estimation Uses on-chain Ethereum transaction data to estimate a wallet’s carbon footprint. Machine learning models analyze transaction types, energy consumption, network energy intensity, and emissions factors. Computes emissions for different blockchain activities, such as NFT minting, token swaps, smart contract executions, and staking transactions. 2️⃣ ZK-Powered Proof of Carbon Neutrality (Brevis EigenLayer) Leverages Brevis ZK proofs to verify that a wallet has successfully purchased and retired an equivalent amount of carbon credits. The ZK proof ensures that: The user has acquired sufficient carbon credits. The offsets were correctly retired. Verification happens without exposing sensitive wallet data. The proof is shared on-chain or off-chain, acting as a CarbonSeal sustainability badge. 3️⃣ Seamless Carbon Offset Purchase & Integration Enables direct on-chain purchase of verified high-quality carbon credits. One-click retirement ensures offsets are permanently credited. Smart wallet integration supports various blockchain wallets. Provides real-time portfolio tracking, allowing users to monitor their net emissions and offset history via an interactive dashboard. Tech Stack Backend Django: Manages the database and API endpoints for transaction data retrieval and storage. FastAPI: Handles AI inference and model retraining for real-time carbon footprint estimation. Go: Implements Brevis ZK Circuits and exposes them via an API. Frontend Angular: Provides a dynamic and interactive web interface for Ethereum transaction queries. Etherscan API: Fetches full transactional history, allowing estimation of a wallet’s carbon footprint. Blockchain & Smart Contracts EigenLayer Brevis ZK Circuits: Determines a wallet’s carbon status: Carbon Negative, Neutral, or Positive. Solidity: Develops smart contracts for tracking and verifying carbon offsets. Ethereum: Serves as the decentralized execution environment. Etherscan API: Retrieves blockchain transaction details for analysis and prediction. Zero-Knowledge Proofs (ZK) Brevis EigenLayer: Provides privacy-preserving zero-knowledge proofs to verify carbon neutrality. AI & Machine Learning TensorFlow: Powers the deep learning model for predicting Ethereum transaction emissions. Model Features: Gas used, gas price, transaction type, network congestion factor, input data size. Neural network layers optimize accuracy in emissions prediction. Uses Huber loss & Adam optimizer for robust estimation. ZK-Powered Carbon Neutrality Verification CarbonSeal integrates Brevis ZK proofs to verify on-chain sustainability efforts securely.

How Brevis ZK Works AI-Based Carbon Estimation: ML models predict emissions per transaction. Carbon Offset Verification: Checks if the user has purchased & retired sufficient carbon credits. ZK-Proof Generation: Verifies offset claims without revealing wallet balances. On-Chain Attestation: Creates an immutable sustainability badge for wallets. API Endpoints GET /ai-carbon-estimation/<address>: Fetches Ethereum transactions and applies AI prediction for carbon footprint estimation. POST /offset-proof: Submits proof of carbon offsetting, generating a ZK-proof of neutrality. GET /verify-proof/<wallet-address>: Returns on-chain verification of a wallet’s carbon offsets. Future Roadmap πŸš€ Deploy as an EigenLayer AVS for network-wide sustainability verification. πŸ€– Integrate with AI Agent Frameworks like Eliza and Ava Protocol. 🌿 Expand tracking to Validator Energy Usage & Off-Chain Emissions. πŸ›‘ Reputation-Based Incentives via GAIA AVS for Greenwashing Detection.

Why CarbonSeal Matters βœ… Prevents Greenwashing: Ensures sustainability claims are verifiable. βœ… Regulatory ESG Compliance: Supports SEC & EU sustainability reporting. βœ… Encourages Responsible Web3 Behavior: Incentivizes climate action. βœ… Privacy-Preserving & Trustless: Uses ZK-proofs for verification. βœ… Modular & Scalable: Can be integrated across Web3 ecosystems.

Conclusion CarbonSeal redefines sustainability in Web3 by merging AI-powered emissions tracking with ZK-proof-based carbon neutrality verification. By integrating EigenLayer AVS, it ensures blockchain sustainability is transparent, verifiable, and impactful. 🌍πŸ”₯πŸš€

How it's Made

How It’s Made: The Tech Behind CarbonSeal CarbonSeal is a cutting-edge Web3 carbon footprint oracle that combines AI, blockchain, and zero-knowledge proofs (ZK Proofs) to estimate emissions from Ethereum transactions and verify carbon neutrality. Below is the deep dive into how we built CarbonSeal.

Brevis ZK Integration – Proof generation for carbon neutrality verification. How the System Works Together 1️⃣ AI-Powered Carbon Footprint Estimation Users input an Ethereum wallet address. Etherscan API fetches transaction history. AI model processes transaction data and estimates the wallet’s carbon footprint. Carbon emissions per activity (NFT minting, DeFi swaps, staking) are calculated. Results are displayed on the frontend dashboard. 2️⃣ Zero-Knowledge Proofs for Carbon Neutrality User purchases and retires carbon credits. Smart contract logs the offset transaction. Brevis EigenLayer generates a ZK proof. Proof is stored on-chain & verifiable without revealing wallet balances. Users receive an immutable CarbonSeal badge verifying their sustainability efforts. 3️⃣ Smart Contract & Blockchain Verification Smart contracts verify carbon neutrality state: Carbon Negative (Emissions exceed offsets) Carbon Neutral (Offsets match emissions) Carbon Positive (More offsets than emissions) Status is reflected in the user dashboard and can be publicly verified. Notable Hacks & Cool Engineering Challenges πŸ’‘ 1. Optimized AI Model with a Singleton Pattern

We use a singleton model loader to avoid reloading the AI model on every request. This boosts efficiency and reduces inference latency. πŸ”— 2. Efficient Blockchain Data Processing
