Motivation • The blockchain Universe generates large amounts of distributed data • However, extraction of knowledge coming from different blockchains is not feasible, since it is a challenge to: • Process the data • Query the data • Inter-link data • Integrate the data • Annonate the data • Blockchains lack software standards that can lead to a global, open, interoperable and semantically rich data space • This comprises the core concept of ISLAND, that is the creation of an interlinked and interoperable semantically-enriched blockchain data ecosystem 3 18th International Conference on the Economics of Grids, Clouds, Systems and Services​ 

Proposed Architecture 4 18th International Conference on the Economics of Grids, Clouds, Systems and Services​ 

Smart Manufacturing Use Case • A supply chain environment extensively uses IoT devices (such as cameras, sensors, etc.) to monitor the chain • Smart-manufacturing services need to exchange machine-readable properties during the entire life cycle, thus facilitating automated, harmonized cooperation between machines (m2m) • Thus, a semantic system is necessary in the smart manufacturing supply chain • ISLAND aims to solve some of the major issues affecting the smart manufacturing supply chain: • An estimated 30% of all global shipments are delayed or lost • Poor regulatory compliance and lack of product traceability jeopardized entire shipments • 50% of all shipping time is wasted as waiting time 5 18th International Conference on the Economics of Grids, Clouds, Systems and Services​

Concussions & Next Steps • ISLAND provides a solution to the blockchain data interoperability challenge and enables arbitrary data sharing among heterogeneous and multiple blockchain protocols • The framework aims to infer meaningful knowledge from smart contracts, while at the same time enabling the semantic interoperability of the data • Fertile layer for marketable interoperable solutions for domains (e.g. healthcare, Industry 4.0, etc.) • Next Steps: • Proof of Concept • Further extend and evaluate the presented approach and implement it on multiple other use cases 7 18th International Conference on the Economics of Grids, Clouds, Systems and Services​
