For SMEs working in industries where product origin, quality, and compliance are critical, blockchain-based supply chain traceability provides a way to build trust and efficiency. Traditional supply chains often suffer from fragmented data—each stakeholder (producers, distributors, logistics companies, retailers) maintains its own isolated records, which can lead to errors, fraud, or delays in verifying authenticity. Blockchain replaces this fragmented approach with a shared ledger where every participant records events in real time, ensuring that all parties see the same trusted version of the truth.
How It Works in Practice
In a blockchain-enabled supply chain, every event—such as harvesting, quality inspection, shipment, or customs clearance—is recorded as a block in the chain. This information can be linked to IoT sensors (e.g., temperature trackers) or QR/RFID tags on products, providing automated updates each time the product is scanned. Each entry is cryptographically signed by the responsible party, making the data secure, verifiable, and tamper-proof.
For example, a food SME could record the harvest date and farm location, storage temperature during shipping, and packaging details at distribution. Retailers and end-customers could then scan a QR code on the product and instantly view the verified history of the item on a blockchain explorer or the company’s website.
The Role of the SAHEL Token
The SAHEL token adds an economic layer to blockchain-based traceability. SMEs can use SAHEL to:
- Incentivize Suppliers and Partners – Reward small producers, logistics providers, or quality inspectors with SAHEL tokens for uploading verified data, ensuring consistent participation in the traceability system.
- Access Traceability Services – SMEs pay in SAHEL to register product events, manage dashboards, or integrate APIs that connect blockchain to ERP/WMS systems.
- Consumer Engagement – End-customers scanning a QR code could receive SAHEL tokens as rewards for verifying authenticity or engaging with the brand, turning traceability into a loyalty mechanism.
This dual role—recording events and rewarding participation—creates a self-sustaining ecosystem where every stakeholder has an incentive to maintain accurate, real-time data.
Technical Implementation Steps
- Network Selection – Use Solana for fast, low-cost traceability updates.
- Identity and Permissions – Assign blockchain wallets (linked to SAHEL) to each participant in the supply chain.
- Event Data Model – Define standardized data points (timestamps, GPS, certifications) and store them as hashed records on-chain.
- Integration Layer – Connect existing ERP/WMS systems or IoT devices via middleware to the blockchain.
- Dashboards & Interfaces – Create web and mobile apps where SMEs monitor traceability and consumers access product history.
- Incentive Mechanism – Use SAHEL tokens for paying transaction fees, rewarding participants, and enabling consumer engagement features.
Example Implementation
A boutique coffee roaster partners with smallholder farmers in South America. Each batch of beans is tagged with a QR code linked to blockchain records containing farm location, harvest date, and certifications. Farmers receive SAHEL tokens as rewards for entering accurate data. As the beans move through exporters, shippers, and roasters, each event is logged on Solana. At retail, customers scan the QR code and not only verify authenticity but also receive a small amount of SAHEL as a loyalty incentive. The roaster gains consumer trust and premium pricing while building a sustainable incentive system powered by SAHEL.
Benefits for SMEs
