Prove where your food came from — not just claim it.
Prairie Ledger is a tamper-evident, hash-chained record of how food actually moves from field to shelf, anchored on a public blockchain so anyone — not just us — can verify it.
Every step, recorded where it happens.
A producer logs each stage in the field. The ledger chains and anchors it. A shopper scans a label and sees the real thing.
Captured at the source
Planting, tending, harvest, or a fresh batch of eggs or milk — logged on a phone, in the field, the moment it happens.
Chained, not edited
Every record links to the one before it. Change one, and the break is immediately visible. There is no quiet edit.
Anchored publicly
Hourly, the chain's current state is anchored to a public blockchain — independent proof that nothing was altered after the fact.
Verified with a scan
No account, no app to download. A shopper scans the code on the label and sees the full, real journey — no signup required.
The Trust Mark for Land-First Agriculture
Every product carrying this mark opens onto its real, unbroken journey — who grew it, what happened at each step, verified against a public ledger that no one, including us, can quietly edit after the fact.
It's not a certification we sell. It's what you get when a claim is backed by a record instead of a label.
Built by producers, for producers.
Prairie Ledger started on our own ground in the Nebraska Sandhills, built to solve a problem we live with directly: the gap between what a food label claims and what anyone can actually verify.
We're not a software company that discovered agriculture. We're a working operation that got tired of that gap and built the record we wished already existed.

One record, three audiences.
The same chain of custody means something different depending on who's looking at it.
For producers
Differentiate on proof, not just claims — and get ahead of traceability requirements headed for the whole industry, on your own terms.
For buyers & retailers
Verify a supplier's claims directly instead of trusting a label and a handshake. The chain of custody is there to check, not to take on faith.
For consumers
Scan the code on the package. See exactly where it came from and what happened along the way — no account, no app, no catch.
Common questions.
What is Prairie Ledger?
A tamper-evident, hash-chained record of how food moves from field to shelf. Every step a producer logs — planting, tending, harvest, or a fresh batch of eggs or milk — is chained to the one before it and anchored hourly to a public blockchain, so the record can be independently verified by anyone, not just us.
Is Prairie Ledger built on blockchain?
Yes. The core record is a hash-chained, append-only ledger, and its current state is anchored to a public blockchain hourly — proof that nothing was altered after the fact, checkable by anyone.
How do I verify where a product came from?
Scan the code on the product's label. No account or app download required — the scan opens the product's full, real journey directly in a browser.
Who built Prairie Ledger?
Prairie Ledger is a Sandhills Sovereign Farms company, based in Merriman, Nebraska — built by a working agricultural operation to close the gap between what a food label claims and what can actually be verified.
What kinds of products can Prairie Ledger track?
Row crops, livestock — tracked either as individual tagged animals or as a group — and livestock products such as eggs and milk.
