Multiple threats have been identified when citizens interact with online services such as unknown provenance of information, unknown quality of service providers, spread of fake news, fraud, personal privacy violation, centralisation of power to name a few. ONTOCHAIN presents a new software framework, that leverages semantic web and blockchain technology to build, as distinct value for the Next Generation Internet, fundamental support for trustworthy data/services exchange and trustworthy content handling.

It comprises a novel protocol suite grouped into high-level application protocols, such as data provenance, reputation models, decentralised oracles, market mechanisms, ontology representation and management, privacy aware and secure data exchange, multi-source identity verification, value sharing and incentives, and lower-level core protocols that include authorisation, certification, privacy-aware data processing, cross-chain gateways, identity management, secure data exchange, and data semantics in smart contracts.

For enabling modularity, scalability, openness and high performance, the ONTOCHAIN platform comprises bottom-up:

  • The distributed ledger technologies layer, where the smart contracts of the various services are deployed,
  • The core protocols layer, where fundamental functionality for building Dapps resides,
  • The application protocols layer where more application-specific functionality resides, the ontologies layer that defines data semantics employed in all aforementioned layers
  • And the applications layer, where Dapps reside combining functionality from the previous layers.
