Blockchain-Based Transaction Manager for Ontology Databases

Knowledge graphs are commonly represented by ontology-based databases. Tracking the provenance of ontological changes and ensuring ontology consistency is important. In this work, we propose a transaction manager for database manipulation that combines blockchain Semantic Web technologies. The latter used efficient querying modification data, whereas secure storage tracking changes. enables decentralized setup data restoration. We evaluate our solution measuring cost time. Our introduces some overhead updates works at same speed as underlying database.
