AirChain — Final Solution

AirChain

“A community-operated system making air quality visible, verifiable, and self-sustaining by anchoring truth on Cardano.”

The System

Resilient Nodes (“Cells”)

• Tolerate intermittent power and connectivity
• Buffer data during outages
• Sync automatically when network recovers

Merkle Data Anchoring

Step	Action
1	Sensors collect air quality readings
2	Readings hashed into Merkle tree
3	Only Root anchored on Cardano
4	Full data provable from single hash

AIRQ Token

• Supply: 1 Billion (pre-minted)
• Purpose: Incentivize stewardship and hardware maintenance
• Mechanism: Rewards for keeping sensors operational

Technical Stack

• FastAPI (Python) — Backend
• Kubernetes — Orchestration
• MQTT — Data ingestion
• Cardano — Aiken/Plutus v3 validator
• PostgreSQL — Local storage

Live Status

✅ Operational on Cardano Preprod Testnet ✅ Aiken Validator deployed ✅ AIRQ Tokens minted

Key Achievement

Successful deployment of the “Environmental Data Anchor Validator” on Cardano Preprod.
