Frequently Asked Questions
Get clear answers on how we deliver secure, tamper-proof verification of environmental data for carbon markets.
Our process follows a secure, multi-stage pipeline: 1) Data Acquisition: IoT sensor data is collected via encrypted gateways. 2) Local Attestation: Data is signed and timestamped at the edge device level. 3) Batch Submission: Aggregated data batches are sent to our relay service. 4) On-Chain Anchoring: A cryptographic hash (Merkle root) of the batch is immutably recorded on a public blockchain (e.g., Ethereum, Polygon). 5) Verification Portal: Stakeholders can verify any data point's integrity via a dashboard by checking its hash against the on-chain record. This ensures data is tamper-proof from sensor to ledger.
