On-chain anchoring writes a cryptographic hash of an animal, batch or product’s canonical record onto the Solana blockchain. The record itself stays private in Farmso; only the hash goes on-chain. Anyone can later re-hash the record they are shown and check it against the anchor — proving it has not been altered since, without having to trust Farmso or any single party.
Farmso reuses Petso’s already-deployed pet_did program on Solana; there is no separate Farmso contract. Animals are namespaced as decentralised identifier (DID) entries in the form farmso:animal:<id>. Farmso manages the keys and pays the network fees, so you get blockchain-grade tamper-evidence without ever touching a wallet or a token.
Use case
An exporter selling a premium beef lot needs to prove its provenance to an overseas buyer. They anchor the batch record on-chain; the buyer scans the product passport and independently verifies that the birth, movement and processing history matches the hash recorded on Solana. The proof holds even if the buyer never trusts the exporter’s systems.
Anchor a record
- 1
Open the record
Go to the animal, batch or product you want to anchor in the web app.
- 2
Anchor on-chain
Choose Anchor. Farmso builds the canonical record, hashes it, and submits the anchor to the pet_did program on Solana.
- 3
Confirm
Once the transaction confirms, the record shows an anchored badge with its DID (farmso:animal:<id>) and a link to verify.
- 4
Share the proof
The consumer/buyer passport now carries verifiable tamper-evidence — no action needed from whoever checks it.

Look for the DID anchor badge
Anchored records show a DID anchor badge on the passport so you can confirm at a glance that the identity is tamper-evident.

Not yet anchored?
Animals that have not been anchored are marked as such — anchoring itself is done from the web app.
On-chain anchoring is an Enterprise feature. Everything else in Farmso works without it — anchoring adds an extra, independent layer of proof for the records that matter most.
FAQ
No. Farmso manages the keys and pays the Solana network fees. You never touch a wallet, a private key or a token — you simply choose Anchor.
