- Team size: 5
- Development time: 6 months
Background
According to the Food and Agriculture Organization (FAO), traceability and supply chain transparency continue to be major priorities in the global agriculture industry. As agricultural products move across multiple intermediaries, businesses increasingly struggle with fragmented data, limited visibility, and inconsistent product origin verification.
For coffee and agricultural supply chains in particular, ensuring transparency from farm to consumer remains highly complex. Products pass through multiple stages, suppliers, and logistics checkpoints, making it difficult for stakeholders to reliably track origin, quality, and handling conditions throughout the process.
To address these challenges, a Singapore-based agriculture company partnered with GEM to build a scalable food traceability platform powered by blockchain and IoT technologies. The goal was to improve transparency, strengthen trust across the ecosystem, and enable real-time visibility throughout the supply chain.
Challenges
In this project, there were 2 major challenges for GEM’s engineers.
Designing a scalable platform for complex supply chains
The client required a food traceability platform that could:
- Support end-to-end visibility across the supply chain
- Enable efficient product origin verification
- Process large-scale operational data in real time
- Deliver a seamless user experience across desktop, mobile, and tablet devices
Processing high-volume IoT data efficiently
This created several technical challenges:
- Maintaining reliable communication
- Managing large-scale real-time data ingestion
- Building scalable cloud infrastructure for IoT workloads
- Optimising analytics performance across multiple data layers
Ensuring data security and stakeholder trust
The challenge was balancing:
- Transparent product traceability
- Secure data management for farmers, suppliers, and end consumers.
- Trustworthy supply chain information
- Scalable platform governance
Solution
To achieve both goals, GEM opted for building a cloud-based platform with seamless scalability and making it accessible via desktop, mobile, and tablets. The whole process needed to be visible to all stakeholders, from upstream to downstream to the end-users.
To maximize data collection efficiency and data transparency, we built a data lake to store and categorize the massive data volume collected from thousands of IoT sensors installed on the farm. Also, we created a dashboard to showcase the outcomes and facilitate stakeholders in tracing all phases of the supply chain.

Impacts
- Improved supply chain transparency: The platform enabled stakeholders to gain greater visibility into product origins and supply chain activities, improving operational transparency across the ecosystem.
- Faster and more scalable data processing: With a cloud-native IoT architecture, the client established a scalable infrastructure capable of handling large-scale agricultural data efficiently.
- Stronger ecosystem trust: By combining blockchain-enabled transparency with IoT-powered monitoring, the platform strengthened trust and collaboration between farmers, suppliers, distributors, and consumers.
- Foundation for future smart agriculture initiatives: The solution provided the client with a scalable digital foundation for future agriculture innovation and data-driven supply chain optimisation.
Closing remarks
This project demonstrates how blockchain, IoT, and cloud-native technologies can transform agricultural supply chains beyond traditional tracking systems. By modernising data collection, aggregation, and traceability processes, GEM helped the client create a scalable and transparent digital ecosystem for smarter food supply chain operations.
