Understanding Granular Aspects of Ontology for Blockchain Databases

Abstract Blockchain technology first appeared a decade ago and is gaining momentum in recent years. The role of ontology to blockchain technology has drawn much attention from researchers. In this paper, we explore ontology in blockchain technology from a unique perspective: Since granular computing can be applied to ontology, it would be a good idea to explore granular aspects of ontology in blockchain technology. Continuing our previous examinations on granular aspects on databases, in this paper, we study granular aspects of ontology for blockchain databases. We provide our own observations, and analyse implications of recent research work related the nature of blockchain technology. As shown in our discussion, this kind of exploration not only helps a better understanding on the nature of blockchain technology, but could also advance the study of granular computing itself.
