The QR code is the door, not the house. aGreen is not simply a QR code on a product: it is the verified record behind the QR, showing where a product was grown, which lots it was made from, who owns it and how it moved.

aGreen Traceability is the supply-chain traceability infrastructure within the aGreen Geo-Blockchain ecosystem. It is designed for agricultural and forestry value chains where where a product comes from, who owns it, which lots it was made from, how much exists, and how it moves between participants are all important.
Instead of treating traceability as a QR code attached only to a finished product, aGreen links the product to its underlying spatial identity, production events, commercial lots, lot genealogy and ownership transfers. This creates a continuous digital chain from the source of production to the international and domestic market.
The central concept is not simply “put a QR code on a product”. The QR code is the door, not the house: it opens the Digital Passport, while the spatial identity, production records, lot genealogy, mass balance, ownership, inventory and transaction relationships behind it are maintained by the aGreen Geo-Blockchain infrastructure.
| A simple QR code | aGreen Traceability | |
|---|---|---|
| What the QR opens | Typically a link to information about a product | A Digital Passport backed by ledger records |
| Origin claim | Typically a document or manually entered claim | Geo-fenced plantation, PUC / MSVT and GPS field evidence |
| Blended or processed lots | Typically not shown | Lot genealogy: source lots, shares and yield |
| Quantities | Typically not reconciled | Mass balance across purchase, processing and sale |
| Ownership and inventory | Typically not tracked | Ownership transfers and inventory events |
aGreen records the genealogy of every commercial lot (also called batch or product genealogy). When coffee, cocoa, pepper or timber is aggregated, blended, split, processed or repacked, the new lot keeps structured links to the lots it was made from.
For each source batch, the Digital Passport can show:
Each source batch links further back to its harvest lot, the plantation unit (PUC / MSVT, geo-fence and GPS field evidence), the farm or organisation that produced it, and the nursery seedling lot where applicable.
Example: a 120 kg roasted coffee lot made from 100 kg of Robusta and 40 kg of Arabica input shows two source batches with shares of 71.43% and 28.57%. Each source batch can be traced back to its own harvest, plantation and nursery records.
A buyer, importer or consumer can therefore see not only where a product was packed, but which farms and plots it contains and in what proportion, even when lots were aggregated, blended, split, repacked or transferred between owners. Mass balance keeps the quantities accountable, and lot genealogy shows which source lots those quantities came from.
For plantation-based commodities, traceability starts before a commercial product exists. aGreen can associate production with a defined Plantation Unit and its geographic boundary.
A Plantation Unit Code (PUC), including the Vietnamese Mã số vùng trồng (MSVT) concept where applicable, provides an important identity for the production area. The geo-fence and production records provide the spatial and operational context behind that identity.
This allows downstream participants to connect harvested material with the production area, cultivation history and supporting field evidence rather than relying only on a document or manually entered origin claim.
For commodities requiring controlled packing operations, the supply-chain record can also associate commercial lots with the relevant packing facility and its applicable Packing Facility Code / Mã số cơ sở đóng gói.
This creates a more complete chain of identity: production unit → harvested lot → processing or packing facility → commercial lot → export/import → distribution → retail → consumer.
QR codes provide a convenient interface for participants to access or transfer information, while the underlying aGreen infrastructure maintains the relationship between spatial identity, lots, genealogy, ownership, inventory, processing and transactions.
Depending on the supply-chain model, a QR code can be used to initiate a purchase or ownership transfer, open a Digital Passport, or allow another participant to verify a commercial lot.
In GS1-enabled scenarios, standardized product identifiers and QR mechanisms can be used for commercial interoperability. This is particularly relevant at interfaces such as Exporter → Importer, where customs and international trade documentation require consistent product and shipment identification, and at Retailer → Consumer where consumers need a simple product-level access point.
The QR code is the door, not the house: it is the access point to the digital record, not the traceability system itself.
Show me QR and Show me QR aGreen represent the same basic idea: use the QR interface to access the relevant aGreen product or Digital Passport information.
aGreen supports 12 domestic routes and 18 international (export ↔ import) routes. Each route shows who can hold or hand off a lot on the ledger. Every route starts at the Farmer. A Nursery step can be placed at the start of any route, and can be skipped for crops that use direct sowing or farmer-raised seedlings.
| Role | Domestic routes | International routes |
|---|---|---|
| Nursery | Optional, at the start | Optional, at the start |
| Farmer | Always first | Always first |
| Aggregator | Optional | Optional, but each route has an Aggregator, a Manufacturer or both before the Exporter |
| Manufacturer | Optional | Optional, same rule as the Aggregator |
| Exporter and Importer | Not used | Always present, in this order |
| Secondary Manufacturer | Not used | Optional, after the Importer |
| Distributor | Optional, before the Retailer | Optional, after the Importer |
| Retailer | Optional, before the end buyer | Optional, at the end of the route |
| # | Route |
|---|---|
| 1 | Farmer → End buyer |
| 2 | Farmer → Retailer → End buyer |
| 3 | Farmer → Distributor → Retailer → End buyer |
| 4 | Farmer → Aggregator → End buyer |
| 5 | Farmer → Aggregator → Retailer → End buyer |
| 6 | Farmer → Aggregator → Distributor → Retailer → End buyer |
| 7 | Farmer → Aggregator → Manufacturer → End buyer |
| 8 | Farmer → Aggregator → Manufacturer → Retailer → End buyer |
| 9 | Farmer → Aggregator → Manufacturer → Distributor → Retailer → End buyer |
| 10 | Farmer → Manufacturer → End buyer |
| 11 | Farmer → Manufacturer → Retailer → End buyer |
| 12 | Farmer → Manufacturer → Distributor → Retailer → End buyer |
The 18 international routes combine 3 origin paths with 6 destination endings (3 × 6 = 18).
Origin paths (before the Importer):
Destination endings (after the Importer):
Whichever route a product takes, the lot keeps its link to the upstream lots it came from, so lot genealogy and mass balance continue across every hand-off, including the export and import step.
A conventional QR system can provide a link to information about a product. aGreen goes further by connecting the QR-accessible product record to the underlying spatial, production, commercial and ownership events that created the product.
aGreen is designed for traceable agricultural and forestry value chains, including:
Typical use cases include provenance verification, farm-to-bag origin checks, anti-fraud controls, sustainable sourcing, export compliance, supply-chain transparency, EUDR-style due-diligence support, inventory accountability and cross-border product verification.
A Geo-Blockchain infrastructure that links spatial identity, production records, commercial lots, ownership, inventory and transactions across agroforestry value chains, from nursery and farm to consumer.
No. The QR code is the door, not the house. It opens the Digital Passport, while the spatial identity, lot genealogy, mass balance, ownership and transaction records behind it are maintained on the aGreen Geo-Blockchain infrastructure.
Yes. Each processed or blended lot links to its source lots with input and output quantities, percentage shares and yield factors, and those links continue back to harvest lots, plantation units (PUC / MSVT) and nursery lots.
aGreen supports 12 domestic routes and 18 international (export and import) routes. Every route starts at the farmer, and a nursery step can be placed at the start of any route. Domestic routes can include an aggregator, manufacturer, distributor and retailer before the end buyer. International routes pass through an exporter and an importer, and can continue to a secondary manufacturer, distributor and retailer.
Yes, through the Digital Passport, subject to the data permitted by each organisation and supply-chain role.
Mass balance keeps input and output quantities accountable across purchasing, aggregation, processing and sales. Lot genealogy records which specific source lots, and in what proportions, a finished lot was made from. aGreen supports both.
No. aGreen Traceability is solely a technical initiative of the independent Vietnam Forest Technology Team (VNFOREST.ORG) that includes experts in technology and agroforestry. It is not the Ministry of Industry and Trade (MOIT) consumer QR scheme, not the Ministry of Agriculture and Environment (MAE) agricultural product traceability platform or its API, and not a system of the Vietnam Administration of Forestry.
aGreen is available through the web platform and mobile application. Field-oriented roles such as nurseries and farmers can use the mobile application to record geo-referenced activities, while manufacturers, exporters, importers and other supply-chain participants can operate through the web and mobile interfaces according to their role.
QR chỉ là cánh cửa, không phải ngôi nhà. aGreen không đơn thuần là mã QR dán lên sản phẩm mà là hồ sơ được xác thực đứng sau mã QR.
aGreen là hạ tầng Geo-Blockchain cho chuỗi giá trị nông lâm nghiệp xuyên biên giới. Nền tảng kết nối nhận dạng không gian, dữ liệu sản xuất, truy xuất nguồn gốc, phả hệ lô hàng, quyền sở hữu, tồn kho, cân đối khối lượng (mass balance) và giao dịch trong một môi trường số tin cậy.
Từ vườn ươm, nông hộ và mã số vùng trồng (MSVT / Plantation Unit Code) đến thương lái, nhà máy, cơ sở đóng gói, xuất khẩu, nhập khẩu, phân phối, bán lẻ và người tiêu dùng, aGreen duy trì mối liên kết của sản phẩm với nguồn gốc không gian và lịch sử chuỗi cung ứng.
Mã số cơ sở đóng gói có thể được gắn với các lô hàng tại khâu đóng gói khi áp dụng. GS1 được sử dụng tại các điểm nhận dạng và giao dịch thương mại phù hợp, đặc biệt trong chuỗi xuất khẩu → nhập khẩu và bán lẻ → người tiêu dùng.
QR và GS1 là lớp giao tiếp/nhận dạng để truy cập thông tin, trong khi hạ tầng aGreen duy trì các mối quan hệ về không gian, sản xuất, lô hàng, phả hệ, quyền sở hữu, tồn kho và mass balance.
Mỗi lô thương mại đã chế biến, phối trộn, tách hoặc đóng gói lại đều giữ liên kết có cấu trúc tới các lô nguồn tạo ra nó. Với từng lô nguồn, Hộ chiếu số hiển thị khối lượng đầu vào, khối lượng đầu ra, tỷ lệ phần trăm trong sản phẩm và hệ số quy đổi, rồi liên kết tiếp tới lô thu hoạch, vùng trồng (PUC / MSVT, hàng rào địa lý, bằng chứng thực địa) và lô cây giống.
Ví dụ: một lô cà phê rang 120 kg từ 100 kg Robusta và 40 kg Arabica đầu vào có hai lô nguồn với tỷ lệ 71,43% và 28,57%, mỗi lô có thể truy ngược tới hồ sơ thu hoạch, vùng trồng và vườn ươm của chính nó.
aGreen hỗ trợ 12 tuyến nội địa và 18 tuyến xuất nhập khẩu. Mọi tuyến đều bắt đầu từ nông hộ; bước vườn ươm có thể đứng ở đầu bất kỳ tuyến nào và có thể bỏ qua với cây trồng gieo hạt trực tiếp hoặc nông hộ tự ươm giống. Tuyến nội địa có thể đi qua thương lái, nhà máy, nhà phân phối và bán lẻ trước khi tới người mua cuối. Tuyến quốc tế đi qua nhà xuất khẩu và nhà nhập khẩu, rồi có thể tiếp tục tới nhà máy thứ cấp, nhà phân phối và bán lẻ.
