   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.

   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

   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

   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.

   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

   ▪ 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

   ❖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

    ❖ 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.

    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

    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!

    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!
