Eight earth-borne entropy axes. One $1,577 bundle. One $99/month subscription. FSMA 204 compliance built in.
FarmGuard is the flagship Loess-Lattice agent. It bundles all eight physical-entropy sensors into a single farm-passport service—signing soil, water, plant, and atmosphere data every 24 hours into a tamper-evident Farm Passport receipt.
FSMA 204 deadline: January 20, 2026. Pilot applications open now.
One hardware purchase installs everything. One subscription keeps your Farm Passport current. No hidden activation fees.
Each axis is a genuine physical-entropy source. The reading is irreproducible from any other location or moment in time. All eight feed the daily Farm Passport signature.
| Axis | Sensor | BOM cost | What farm event it attests |
|---|---|---|---|
| Axis 17 | Soil Microbial Noise | $82 | Soil health, organic matter content, no-tillage claim, fertilizer absence. Electrical conductance from 109–1010 microbes per gram is unique per farm. |
| Axis 18 | Chlorophyll Fluorescence | $620 | Crop health at harvest, pesticide-absence claim, growing-season authenticity. Quantum yield variation in Photosystem II is plant-specific and day-specific. |
| Axis 19 | Water Turbulence Acoustic | $475 | Irrigation source identity, water quality attestation, PFAS-free claim support. Broadband acoustic signature of flowing water is source-and-moment-specific. |
| Axis 20 | Atmospheric Ion Count | $32 (combined) | Harvest timing verification, growing-area geo-fingerprint. Cosmic ray and radon ionization events are geographic and temporal. TRL 9. |
| Axis 21 | Animal Biometric Noise | Livestock add-on | Not included in base FarmGuard bundle. Available via LiveStockPass add-on for farms with integrated livestock operations. |
| Axis 22 | Seed Germination Timing | Seasonal reading | Planting-date claim, seed lot authenticity, variety attestation. Stochastic radicle emergence timing is unforeseeable at signing time. |
| Axis 23 | Pollinator Flight Camera | $185 | Pesticide-absence attestation (pollinator presence as proxy), organic-practice verification. Random flight dynamics of honeybees captured via optical sensor. |
| Axis 24 | Weather Sensor Jitter | $32 (combined) | Growing-area micro-climate fingerprint, frost date claim, irrigation-need record. Micro-temporal jitter in temperature and humidity sensors. TRL 9. |
Axes 20 and 24 share a combined $32 weather/ion sensor. Axis 21 is available via the LiveStockPass add-on. All other axes are included in the $1,577 base bundle.
Every farm enrolled in FarmGuard receives a passport structured like the one below, issued daily, and anchored to Base mainnet.
FDA Food Safety Modernization Act Section 204 requires specific Key Data Elements at every Critical Tracking Event. FarmGuard captures each one at the farm side automatically. Deadline: January 20, 2026 for farms serving covered produce.
FarmGuard is in pilot stage. FSMA 204 integration has been designed and specified but is not yet production-tested against an FDA inspection. The passport structure aligns with FDA guidance published through May 2026. Farms should maintain their existing recordkeeping in parallel during the pilot period.
All sensors wire to a single weatherproof gateway enclosure. The gateway connects to cellular or satellite uplink. No IT staff required. Installation takes 2–4 hours with the included integration kit.
FarmGuard is accepting three pilot farms. Hardware and subscription are provided at no cost for the first six months in exchange for case-study rights.
To apply, send an email describing your farm (acreage, primary crops, current traceability setup) to Steve Rotzin directly. Pilot slots are awarded in the order qualified applications are received.
FSMA 204 compliance has historically required expensive software subscriptions, consultant hours, or audit fees. FarmGuard Year 1 totals $2,765 with hardware included.
| Option | Year 1 cost | Ongoing cost | Cryptographic proof | FSMA 204 auto-generation |
|---|---|---|---|---|
| FarmGuard | $2,765 $1,577 hardware + $1,188 sub |
$1,188/year | Yes — Ed25519 + ML-DSA-65 | Yes — all 7 KDEs |
| Traditional FSMA 204 software | $5,000–$25,000/year | $5,000–$25,000/year | No | Partial — manual entry required |
| HACCP consultant (per-hour) | $300/hour — varies widely | Ongoing retainer | No | No — manual documentation |
| USDA certified-organic audit | $800–$2,000/year | $800–$2,000/year | No | No — separate requirement |
FarmGuard is additive to USDA organic certification, not a replacement. Costs above are representative market ranges as of Q2 2026. FarmGuard is in pilot stage; production pricing may differ.
FarmGuard is in active development. Dates are targets, not commitments. All milestones are subject to pilot learnings.
The soil has always been signing. Now we can read it.
