A prominent example is the track and trace case for tuna to combat illegal fishing. Using devices for tracing (e.g. RFID tags, QR codes, NFC devices, or cameras), information about the fish can be collected at almost any point throughout the supply chain (Visser and Hanich, 2018). As the data is recorded on a transparent and immutable registry, each fish can be tracked back to its origin by respective regulators, NGOs, and consumers. The technical implementation of this use case can be applied to other natural capital in agriculture, livestock, and forestry.
