Blockchain Farm Ledger

Farm-to-Fork:
Technology That Records Trust

Not a farming log filled in by hand, but an "IoT + Blockchain" fusion model that couples automatically with environmental controllers (IoT) to secure the trust of global buyers.

Recorded in the Field,
Trusted on the Blockchain

This is a mobile farming log already in operation. When you record a pesticide application, it automatically shows the PLS (Positive List System) recommended standards and calculates the spray volume from the plot area and dilution ratio. Records captured in the field this way become the source of the blockchain trail.

  • Automatic PLS safe-use guidance — dilution, timing, and frequency standards by crop and target pest
  • Automatic area and usage conversion — spray volume calculated automatically from plot area and dilution ratio
  • Record → immutable trail — accumulated automatically into the blockchain farming log the moment it is entered
Trust Pipeline

Four Steps to Building Trust

1 · IoT Data Capture

Data Collection

Sensors and FarmNavi collect soil, climate, and input data in real time. With no human handling, there are no omissions or distortions.

2 · Immutable Traceability

Immutable Trail

Collected data is recorded automatically in the blockchain farming log (Digital Ledger). Polygon anchoring makes it immutable.

3 · Smart Contracts

Smart Contracts

When preset quality and delivery conditions are met, automatic payment is triggered — securing the producer's cash flow.

4 · Consumer Engagement

Consumer Verification

Through digital certificates and QR codes, the end consumer instantly verifies the cultivation history.

Green is the farm's act of recording; the steps that follow form a tamper-proof chain of trust.

Verifiable Output

The output is a document anyone can verify

A farm log report issued by Agrisys ADAS. Blockchain anchoring hashes are printed alongside the work records, so whoever receives the document can verify the original themselves.

Farm log report title block — period, total records, issue time and issuing system Agrisys ADAS
Issue details — period, record count and issue time are fixed at the top of the document
Pesticide table in the report — product, dilution, volume, target pest and PLS registration
Pesticide record — dilution, volume, target disease and PLS registration in one table
Blockchain integrity table — verified status, Log Hash, Merkle Root, TX Hash, Polygon, anchoring time
Blockchain integrity — Log Hash, Merkle Root, TX Hash and the Polygon anchoring time
Verification QR code printed on the report — scan to confirm the original
The verification QR printed on the document — scanning opens the original check page
  • Verified with one scan — The printed QR lets the recipient confirm the original on the spot
  • Any edit changes the hash — Log Hash and Merkle Root prove the document has not been altered
  • Anchored to a public chain — Anyone can cross-check the TX Hash directly on Polygon
  • PLS-ready records — Submit proof of compliant pesticide use as a document, immediately

Why It Matters

Not "Trust Us,"
but "Verify It Yourself"

  • GAP & organic certification — the cultivation records needed for audits are prepared automatically
  • Export competitiveness — prove trust to global buyers with verifiable data
  • Brand value — deliver transparency to consumers with a single QR code
  • Dispute prevention — identify the cause of quality issues with objective data

Proven Technology Already in Operation

The FarmStack farming log (farming.farmstack.kr) is running on real farms with Polygon blockchain anchoring and QR verification.
