Satellites, field agents, RFID systems, contracts, and market feeds observe agricultural work. The oracle turns selected events into privacy-preserving records that can support milestone finance, monitoring, and future RWA infrastructure.
C-band radar can see through cloud cover and flag land preparation activity by date, plot, scene ID, and confidence score.
Vegetation time-series tracks crop development, stress, and forecastable yield signals before harvest.
RFID intake, photo evidence, veterinary checks, and ML body-condition scoring create auditable livestock lifecycle records.
Contract-farming agreements and plot boundaries are hashed, versioned, and connected to the production cycle without exposing sensitive terms publicly.
Feed, live-animal, carcass, and logistics price observations can be published as timestamped oracle feeds for underwriting and settlement.
Tranche approvals, repayment events, settlement evidence, and production outcomes build portable credit evidence while sensitive scores stay off-chain.
Satellite, field-agent, RFID, contract, or market data is submitted with source, timestamp, location, and supporting metadata.
The event is marked green, yellow, red, or conflict based on automated checks and human review rules.
The oracle records a hash or event attestation. The on-chain record carries proof, not funds.
Financing parties disburse local currency to approved service providers or operators through off-chain rails and contracts.
No funds move on-chain — the chain carries verified data only. All money exchanges are fiat.
Evidence is consistent across sources and above the required confidence threshold.
Clouds, small plots, mixed cropping, boundary mismatch, or unusual livestock data require supervisor review.
Satellite, agent, producer, or contract evidence disagrees. Additional evidence, override, or appeal is logged.
| Field | Example | Privacy Model |
|---|---|---|
| plot_id / animal_id_hash | Farm plot or RFID-linked livestock batch | Hash or permissioned identifier |
| verification_type | SAR plowing, NDVI health, BCS score, contract registered, price feed | Public event label |
| source + timestamp | Sentinel scene, field app, RFID reader, market survey | Public metadata, private raw evidence where needed |
| confidence_score | 0–100 plus green/yellow/red/review status | Public or permissioned depending on use case |
| evidence_hash | Photo set, GeoJSON, signed inspection, contract PDF | Hash on-chain, source file off-chain |
| tranche_event_id | Approved, rejected, reviewed, settled | Event attestation only; no custody of funds |
| credit history | Repayment and settlement outcomes | Sensitive data stays off-chain; only summaries or attestations anchored |
Underwrite against verified production instead of only land collateral. Monitor funded farms from onboarding to settlement. Use oracle records as evidence for credit, insurance, offtake, and future tokenized receivables — with legal contracts and regulated partners still controlling the actual finance.
