On-Chain MRV (Measurement, Reporting, and Verification) is the practice of recording carbon and environmental impact data directly on a blockchain to create tamper-evident, auditable proof of climate actions. It combines sensor data, satellite imagery, and oracle feeds with on-chain attestations so that carbon credits and sustainability claims can be independently verified. By anchoring MRV data to an immutable ledger, it reduces double-counting and greenwashing in voluntary and compliance carbon markets.

- The approach ingests sensor, satellite, and oracle data, attesting it on-chain so carbon credits carry a transparent provenance trail. This mitigates double-counting and greenwashing by making verification continuous and publicly inspectable rather than reliant on periodic manual audits.
