Boat or pen to buyer traceability
Hypothetical. Not a client, not a result.
// The problem
Buyers ask harvesters and processors where each lot came from, and the answer is pieced together from landing slips, pen records and processor sheets passed along by email.
// What we would build
A traceability system where harvesters or farms, the processor and buyers each record their step against the lot, with each record fingerprinted on a private permissioned ledger the parties each run a node of, and a QR code on each case that shows buyers the lot's path in their language. A shared database run by the processor often does this job; the ledger helps when several harvesters, processors and buyers share one record and none wants to hold it for the others.
// What is in it
- Catch or harvest, landing, processing and shipping recorded against each lot
- Each step fingerprinted on a private ledger with a node for each party
- A QR code on each case that shows buyers the lot's path
- Buyer pages in English, French, Japanese and other languages you choose
- Only what each party agrees to share is shown to buyers
