Climate Action Tracking & Data Sharing

Open Climate Collabathon 2019 (Yale-NUS College, Singapore)

Architecture

Blockchain for data availability + smart contract enforcement

• data analysis smart contract
• encrypted emissions data (PoC: assume numerical and standard data format)
• goal fulfilment smart contract
• publicly declared reductions goals
• stake deposit

Trusted execution environment (TEE) for machine learning

• INPUT: encrypted data, ML weights
• COMPUTE: sentiment analysis for bad actor prediction, data cleaning, outlier detection
• OUTPUT: cleaned encrypted data, bad actors, updated ML weights

Homomorphic statistical aggregation

• INPUT: cleaned encrypted data
• COMPUTE: aggregate statistics on cleaned encrypted data
• OUTPUT: decrypted aggregate result, proof of decryption

Incentives

• Reporting accurate data
• Making reduction commitments
• Fulfilling reduction commitments
