About aGreen

A trusted infrastructure for cross-border agroforestry value chains

aGreen combines Hyperledger Fabric, geospatial (GIS) data, and field-based digital records to connect agroforestry production with its physical origin. Verified geographic areas, unique MapIDs, geo-fencing, and tamper-resistant field evidence create a trusted spatial foundation for traceability, from nursery and farm to processing, logistics, and the final buyer.

Each lot and product can be identified through a Digital Passport accessible through GS1 Digital Link. Anyone can scan the GS1 QR code with a standard smartphone camera to access product identity, origin, and traceability information without needing the aGreen app. When a purchase or transfer is required, the transaction can move into the aGreen network, where product identity, inventory, ownership, and mass balance remain connected throughout the supply chain. This creates a simple bridge between globally accessible product information and a trusted transaction infrastructure.

"Show me QR aGreen"

Some cases in daily life with aGreen

A simple question at the fruit counter

A shopper in Hanoi picks up a box of Shine Muscat grapes labelled Product of Korea. She asks the seller, "Are these really from Korea?" Without verifiable product data, she has little choice but to trust the label and the seller's words. She then asks a simple question: "Show me QR aGreen."

The questions behind the label

The QR code opens the product's Digital Passport through a GS1 Digital Link. She can check the product identity, verified origin, production area and supply-chain history. Where relevant, production, treatment, harvest and testing records can also be linked to the specific lot. Now the question is no longer simply whether she trusts the seller. She can verify the product before buying.

The same question, across borders

Days later, a student in Tokyo sees Vietnamese lychees labelled Hung Yen, Vietnam. She has the same question: "Can I verify where these really came from?" She scans the QR code. The same Digital Passport is accessible from the other side of the world. The product carries a globally accessible digital identity, connecting the physical product with its verifiable origin and supply-chain history.

And the story continues to the transaction

The same principle applies beyond the supermarket. An importer or inspection authority can access the digital identity and relevant supply-chain records of a shipment, while official documents remain part of the formal process. When a buyer chooses to purchase through aGreen, the transaction moves into the aGreen network, connecting product identity, ownership, inventory and mass balance throughout the supply chain.

Don't just trust the label. Tell the seller "Show me QR aGreen."

From a shopper checking imported fruit in Hanoi to a buyer verifying Vietnamese produce in Tokyo or anywhere in the world, the principle is the same: verify before you trust, and connect the product to the transaction.

A globally accessible product identity, connected to a trusted transaction infrastructure.

Roles on the supply chain

Each participant contributes data to the lot's Digital Passport. Below is how parties collaborate in the model aGreen supports, which can be expanded or simplified to suit your organisation.

Nursery - 📱

Starts the product lifecycle by issuing seedlings, seedling batches and provenance records. Geographic data and issuance timestamps are recorded so that every subsequent step can be traced back to the correct plant source.

Farmer - 📱

Plants, cultivates, cares for and harvests within verified geographic boundaries, supported by field evidence such as geo-tagged photographs and activity logs. This is where verified raw-material volumes enter the supply chain.

Aggregator - 📱

Aggregates, sorts and transfers raw materials between farmers and processing or consumption stages; records transactions, documents and lot ownership transfers to maintain continuity throughout the traceability chain.

Manufacturer - 🌐📱

Performs primary or further processing while recording changes in quantity, by-products and quality indicators. New outputs are linked to verified inputs so that the Digital Passport accurately reflects the production process.

Exporter - 🌐📱

Handles export packing, customs procedures and international logistics; links export documentation with lots on aGreen to maintain seamless cross-border reconciliation.

Importer - 🌐📱

Receives goods at the destination, manages import procedures and organises domestic distribution. Reconciles lots and documentation with the international journey recorded on aGreen.

Secondary Manufacturer - 🌐📱

Performs further processing, blending, repacking or creates new finished products from verified inputs already on the chain. Declares inputs and outputs so provenance is preserved when the product changes form or composition.

Distributor - 🌐📱

Distributes products to retailers or consumers while maintaining the identity and status of each lot throughout the distribution process.

Retailer - 🌐📱

The final point of contact before the buyer: receives, manages and places products on the retail market. The QR code provides immediate access to the product identity and Digital Passport before purchase.

Consumer - 📱

Purchases products at retail or online while having the ability to independently verify product information before deciding to buy.

Traceable product flows

Representative logistics flows showing who can hold or hand off a lot on the ledger. The diagrams list Nursery first for species that use one; your actual chain may omit that step (see note).

Nursery is optional. Many crops use direct field sowing or farmer-raised seedlings, and those flows start at Farmer only. The amber tiles mark the nursery stage wherever it may be skipped.

Domestic (in-country)

Flows that stay inside a single marketplace, from farm gate to households directly, via retail shelves, wholesalers, aggregators or processing plants.

International (export ↔ import)

Cross-border journeys add exporter and importer nodes; traceability connects origin country production with destination distribution or further manufacturing.

Supply-chain step details

Business descriptions; live UI may differ by deployment version.

Nursery - 📱

  • Register and verify identity with an aGreen platform user account.
  • Register and verify the geographic area as a geo-fence defining the nursery boundary.
  • Record sowing and subsequent care activities according to silvicultural logic and the verified geo-fence. The system does not allow activities to be recorded outside the registered boundary.
  • When seedlings reach the required age or readiness, create a QR code to sell all or part of the remaining stock to farmers.
  • Manage remaining seedling stock, including further sales or technical write-offs for returned, dead or culled seedlings according to applicable procedures.
  • Perform other business activities according to the organisation's configuration and policies on the platform.

  • Register and verify the production area as a geo-fence defining the planting or cultivation boundary.
  • Record activities such as purchasing seedlings from nurseries for tree crops, planting, fertilising, irrigation, crop protection and other operations. Each activity is geo-tagged and supported by field evidence, while the system checks it against the verified geo-fence.
  • Harvest according to silvicultural and geo-fence rules to create verified raw-material lots, either fresh or primarily processed; issue a QR code and transfer ownership of part or all of the lot to an aggregator, manufacturer or consumer according to the product's market model.
