Five handoffs, each one checked by a person.
Between the field and the buyer, Kalanamak changes hands five times. At each one someone records what changed hands, and the next person checks it before the rice can move on.

What if someone tries to add other rice?
At the collection centre, every bag has to be linked to a registered farmer. Rice that can't be linked is turned away, and the attempt is noted.
At the mill, the rice that comes out has to match the paddy that went in. If the numbers don't add up, the lot is flagged before it can be packed.

Why changes can't be hidden
Each record carries a fingerprint of the one before it.
If anyone edits an old record, its fingerprint changes and the next record no longer matches. Keep scrolling to see it happen, or flip the switch yourself.

FAQ
Who actually checks the rice?
People do. Trained field staff register farmers, and at every handoff the next person in the chain checks the record before the rice moves on. The software keeps the record; it doesn't replace the people checking it.
Is this blockchain?
No. Each record carries a fingerprint of the one before it, so if anyone changes an old entry, it shows. There are no tokens or cryptocurrency involved.
Do farmers need a smartphone?
No. Our field staff register farmers and record their sales on their behalf.
Does AI decide what's genuine?
No. People check the rice and the records. The software keeps the history straight.
