Yeah, it’s a neat idea on paper. If the data’s truly tamper‑proof and everyone sticks to the same ledger, you could verify where a crop came from, what inputs it used and even monitor forest impact. In practice the devil’s in the details—getting farmers to log everything accurately, the cost of the infrastructure, and making sure the smart contracts actually enforce the sustainability standards. Still, a well‑designed system could reduce fraud and build consumer trust, but it won’t solve the whole supply‑chain mess without a solid plan for adoption and governance.
