2. | ONTOCHAIN.NGI.EU ONTOCHAIN 7 CORE PARTNERS
3. | ONTOCHAIN.NGI.EU 3 ONTOCHAIN ONTOCHAIN - Trust traceable and transparent ontological knowledge on blockchain, is a European project funded by the European Commission under the European Union’s Horizon 2020 Research and Innovation Programme, and part of the European Commission’s Next Generation Internet (NGI) initiative. ONTOCHAIN was launched in September 2020 to empower innovators and end users through 3 Open Calls to develop blockchain-based knowledge management solutions that will be part of a novel software ecosystem for a better share of knowledge and value. 3
4. | ONTOCHAIN.NGI.EU HOW? WHERE DO WE STAND? ✔3 Open Calls with up to Up to 4,2 M € funding ❖ OC1 Research : Design Specifying the ONTOCHAIN framework as human centric decentralised & trustworthy solution based on available technologies. A first batch of specifications have been delivered by 17 Teams in phase one of the call and 7 remaining Teams will delivered the full ONTOCHAIN framework in September 2021. ❖ OC2 Protocol suite and software ecosystem foundations : Implementation Building the ONTOCHAIN concept for the creation of a trustworthy information/service exchange process & a more trustworthy content handling. This call aims to deliver the ONTOCHAIN Framework prototypes. ❖ OC3 Application and experimentation : Deployment 2022 Progress Now
5. | ONTOCHAIN.NGI.EU TODAY ✓ Participate in the generation and use of knowledge like never before. ✓ Digital life is an extension of our physical world.  Centralization of power  Unknown provenance of information  Anonymity and unreliable identities  No fair rewards for good quality contributions ➢ The way knowledge is generated, curated and stored raises effectively some concerns and it is the time to handle our digital life with the same critical, moral and ethical thinking that we use in our physical world
6. | ONTOCHAIN.NGI.EU FUTURE The internet of the future should be more Resilient Trustworthy Sustainable ONTOCHAIN approach is to leverage Semantic Web and blockchain assets to built as a distinct added value for the next generation internet.
7. 7 SEMANTIC WEB 7 BLOCKCHAIN Set of technologies that focus on data, i.e., how they are described, modelled, and linked. A technology that aims at storing data and share such data among a set of peers, who validate the content without the intervention of a third-party services. Trustworthiness is achieved by standardised storage and ontologies on one hand as well as on the other hand by the decentralisation and data immutability ONTOCHAIN
8. | ONTOCHAIN.NGI.EU ▪ Addressing the information needs of semantically complex, dynamic, trust- critical ecosystems ▪ Trusted data, metadata, ontology, knowledge and information management ▪ Ontologies + Blockchain ▪ Permissioned, Regulated by the people ▪ Fostering plurality and democracy ▪ Trusted, on-chain approaches ▪ Trustless, off-chain approaches, Smart Oracles ▪ Expected outcome: ▪ New ONTOCHAIN application design ▪ New ONTOCHAIN software ecosystem ONTOCHAIN
9. | ONTOCHAIN.NGI.EU ❖Shall the door of our home automatically open to an unexpected visitor? ❖Should I borrow my car to my neighbor? ❖Who will gain access to my video stream for processing? ❖Can we trust the sensors and the traffic lights on the smart crossing? ❖Can we trust the documents in the archive? ❖When I move my smart car from Ljubljana to Vienna what happens with my transactions? ❖Who can access my files? Trust-critical use cases
10. | ONTOCHAIN.NGI.EU ❖ Multi-layer and modular technology framework ❖ Address the various challenges of the Next Generation Internet ❖ Different protocols and interactions between different blockchain frameworks. ❖ Enable higher performance and scalability ❖ Transparent content and information exchange as well as service interoperability ❖ Building block of NGI towards a more human-centric Internet ONTOCHAIN STRATEGIC OBJECTIVES
11. | ONTOCHAIN.NGI.EU KEY OBJECTIVES ❖ Reputation management Generic decentralized reputation management functionality in the blockchain and different decentralized reputation models ❖ Trusted data semantics Bring data semantics in the blockchain framework, so as to track data provenance, data handling and data manipulations throughout the data lifecycle. ❖ General data protection and marketplaces based on trusted knowledge and information Address several challenges to unlock the tremendous potential of blockchains, especially before this paradigm shift becomes technically, economically and legally viable in business environments.
12. | ONTOCHAIN.NGI.EU ONTO-BLOCK ❖ On-block storage of ontologies, instances ❖ Information replication based on security needs ❖ Possibility for split and join operations with ONTOBLOCKs ❖ Quality of Service managements with trade-offs for ONTOBLOCKs: in memory, temporary usage of blocks, storage for indefinite time, number of replicas versus storage cost etc. ❖ Trusted approaches for ontologies and metadata management ❖ Trusted approaches for data management ❖ People, resources ❖ Data, Metadata, Knowledge, Information ❖ Internet of Things ❖ Microservice containers ❖ Edge-to-Cloud infrastructures ❖ Artificial Intelligence algorithms ❖ Digital Twins ONTO BLOCK T R U S T
13. | ONTOCHAIN.NGI.EU THE KNOWLEDGE BLOCK TREE AND FOREST Trees of ONTOBLOCKs may form a Knowledge Block Forest ❖ Designed for indefinite usage ❖ Supporting services for continuous Knowledge Block Forest operation: ❑ ONTOBLOCKS split & join ❑ ONTOBLOCKs archiving ❑ ONTOBLOCKs defragmentation ❑ In memory ONTOBLOCKs ❑ High security ONTOBLOCKs ❑ Moving blocks vertically or horizontally ❑ Local versus Global decision making ❖ Geographic mapping of ONTOBLOCKs ❖ Top blocks have much higher security, are kept in memory, regularly copied between countries ❖ Trust in the provided information!

14. | ONTOCHAIN.NGI.EU ONTOCHAIN FRAMEWORK : MAPPING ACCORDING TO THE 3 OPEN CALLS
15. | ONTOCHAIN.NGI.EU ONTOCHAIN AMBITION 15 At the end, ONTOCHAIN will deliver a complete software ecosystem and novel, ambitious Distributed Ledger Technology (DLT) applications in areas such as : ❖ Trustworthy web and social media ❖ Trustworthy crowdsensing ❖ Trustworthy service orchestration ❖ Decentralised and unsupervised online social networks Successfull : if this ecosystem of innovative applications is widely and sustainably adopted by vital sectors of the European economy. That is our intention!
