- Describe your company in one paragraph.
iLINK (iLINK Nees Texnologies OE) is a Greek SME founded in 2005, headquartered in Athens, specializing in enterprise software, IoT, and telematics solutions. With over 20 years of experience, iLINK serves more than 1,000 companies and public organizations across fleet management, industrial IoT, and distributed systems. Our flagship products include PowerFleet (fleet management with GPS tracking, fuel monitoring, and route optimization) and PowerTech (mobile workforce management). iLINK holds ISO 9001 and ISO 27001 certifications and has a proven track record in EU-funded R&D projects including COP-PILOT (Hyperledger Fabric for agrifood traceability), P2CODE, 5G-INDUCE, KIRO, and multiple Horizon Europe cascade-funded initiatives. Our core expertise spans blockchain/DLT integration, edge computing, real-time sensor data processing, and Cloud-Edge-IoT architectures.
- What challenge are you addressing under the O-CEI Horizon’s first Open Call, and how is your proposal relevant to the challenge?
HALLOTRACE addresses Challenge P5C1 — “Dairy product Traceability System based on Distributed Ledger Technologies” — under Pilot 5 (Energetically and Environmentally Sustainable Halloumi Cheese Production) in Cyprus. The challenge requires a DLT-based system that enhances dairy-cheese traceability from farm to fork, ensuring transparency, authenticity, and food safety through a tamper-proof, decentralised ledger with a focus on energy consumption tracking.
Our proposal, HALLOTRACE (Halloumi Energy Aware Traceability Ledger), directly addresses this by building an end-to-end, energy-aware traceability system for the halloumi supply chain. The solution integrates IoT sensor data from farms, transport vehicles, and the processing factory with a permissioned Hyperledger Fabric blockchain. All data is structured as GS1 EPCIS 2.0 supply chain events with SAREF semantic annotations and stored directly on the Fabric world state — making the blockchain the single source of truth. The system tracks four supply chain stages: milk reception (ObjectEvent), transport with cold-chain monitoring (ObjectEvent), factory processing (TransformationEvent), and packaging (AggregationEvent). At each stage, energy consumption data is captured and correlated to compute per-batch KPIs including kWh/kg, CO₂ equivalents, and renewable energy ratios. A consumer transparency web application enables end consumers to scan a QR code and view the complete batch journey with energy and environmental metrics. HALLOTRACE was selected with an evaluation score of 14.00/15.00 (Excellence: 4.50, Impact: 4.50, Implementation: 5.00).
- What is the expected impact of your proposal?
HALLOTRACE’s expected impact spans three dimensions: industry, environmental, and technological. At the industry level, the system delivers full batch-level traceability with energy footprint data across the entire halloumi supply chain — from farm energy monitoring through transport logistics to factory processing. This fills a critical gap in the Cypriot dairy sector, where no existing system links per-kilogram energy consumption to individual product batches. The consumer-facing transparency application, accessible via QR code, strengthens consumer trust in halloumi’s PDO authenticity and sustainability credentials, directly supporting the EU’s Corporate Sustainability Reporting Directive (CSRD) requirements.
Environmentally, HALLOTRACE enables precise monitoring and reduction of energy consumption and CO₂ emissions across the supply chain. By computing real-time KPIs — energy per kilogram (kWh/kg), renewable energy ratio per batch, and carbon equivalent per stage — the system provides actionable data for producers to optimize energy use, prioritize renewable sources, and reduce their environmental footprint. Transport emissions are tracked via vehicle telematics with OBD-II data and cold-chain temperature monitoring ensures food safety compliance.
Technologically, HALLOTRACE delivers reusable, containerized Cloud-Edge-IoT assets published to the O-CEI federated marketplace — including documented APIs, Kubernetes deployment blueprints, and Hyperledger Fabric chaincode — applicable to other dairy and agrifood supply chains across Europe. The architecture demonstrates that direct on-chain storage of sensor values (not just hashes) is viable for supply chain traceability, simplifying auditability and eliminating off-chain storage complexity.
