The ONTOCHAIN Project
Up to 4.2 Millions € funding and mentoring program with best international experts in
Semantic Web, Linked Data, ontology engineering, Blockchain interoperability, knowledge
management, distributed and decentralised computing, business models for trusted
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.
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.
The internet of the future should
be more resilient, trustworthy
More than ever, our digital life is an extension of our
physical world. It is now possible for citizen from all over
the world to participate in the generation and use of
knowledge like never before.
However, from the current standpoint and when it comes
to exchange of knowledge, Internet can’t assure that
bias or systematic abuse of global trust are avoided.
The way knowledge is generated, curated and stored
raises effectively some concerns. Citizens everywhere
are at risk of being presented partial or biased
information reflecting the viewpoint of their provider.
It is thus time from now on, to handle our digital life
with the same critical, moral and ethical thinking that
we use in our physical world.
The ONTOCHAIN project aims to develop a new
software technologies stack at the meeting point
between the Semantic Web and Blockchain to enable
trustworthy data and services exchange as well as
trustworthy content handling for different domains e-
Education, e-Health, e-Government, e-
Commerce, e-Tourism, e-Infrastructures, Industry 4.0
entertainment, and so forth.
ONTOCHAIN DEVELOPMENT & IMPLEMENTATION
3 Open Calls with up to Up to 4,2 M € funding – Codesign & Win-Win Exploitation
OC1 Research - 1.14M€
OC2 Protocol suite and software ecosystem foundations - 1,32M€
OC3 Application and experimentation - 1,75M€
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.
Building the ONTOCHAIN software ecosystem, for the creation of a trustworthy information/service exchange
process & a more trustworthy content handling. This call aims to deliver the ONTOCHAIN Framework prototypes.
Exploit the ONTOCHAIN solution for real life use cases.

ONTOCHAIN OC2 CONTEXT :
VISION ARCHITECTURE & SOFTWARE DEVELOPMENT
ORTHOGONAL VIEWPOINTS OF OPEN CALL 2
Framework prototypes as human centric decentralized and trustworthy solution
Specific software solutions that can be used widely
Trustworthy information/service exchange process
More trustworthy content handling
Extending the use case and the architecture plan of ONTOCHAIN open call 1
Trusted, traceable and transparent ontological knowledge management
Trustworthy metadata in the context of trading any kind of real or digital
Trust of the provided information
Identities and verifiable credentials
Verifiability (Verify/certify the properties of the entities)
Ownership, versioning, manipulation, trading, part-tracking
Semantic blockchain-based information.
THE TRUSTWORTHY SEMANTIC MARKETPLACE
Design, implement and showcase trustful and trustless oracle prototypes that can interact with the
ONTOCHAIN infrastructure and providing necessary data for the operation of its applications
Definition of APIs for common (generic) use cases
Integrate with at least Ethereum smart contracts and the EVM, although support for additional chains is
Support for semantic data (e.g., properties such as a vehicle color) and semantic queries (e.g., via SPARQL)
Support a variety of data sources, data formats and off-chain storage mediums/services
Integration of identity verification or decentralized identity management
New trust-building mechanisms to assure authentic and trustworthy data feed for smart contracts.
1. DECENTRALIZED ORACLES
Motivations: Design, implement and showcase prototype services in the scope of advanced decentralized
market and business-enabling mechanisms that offer win-win situations for all involved stakeholders, and
are in line with the overall ONTOCHAIN objectives for trustworthy services/products exchange and
trustworthy content handling.
Support for token minting, distribution (for ecosystem economic sustainability) and exchange
Support for developing unbiased trustworthy marketplaces of digitized (physical or virtual) assets
Support for unbiased decentralized price determination mechanisms
Support for service/product exchange
Support for building efficient DeFi applications
Design economic model prototype for all stakeholders
2. MARKET MECHANISMS FOR ONTOCHAIN
Motivations: Bi-directional operations (e.g., transfer of information and assets) between the ONTOCHAIN
network and a selection of the most widely used networks, as well as communications between different chains
within the ONTOCHAIN network.
The topic is open to any existing blockchain solution but at least Ethereum, Tezos and Hyperledger Fabric must
Support for (at least) ERC-20, ERC-721, ERC-777 and ERC-1155.
Solutions must rely as much as possible on industry-wide standards and support existing chains with no
modifications of their protocols, clients, virtual machines or programming framework.
The trust, validity and critical metadata attached to data/transactions must be preserved during a transfer within
ONTOCHAIN and with external blockchains.
Provide efficient methods for reducing computational complexity and transaction sizes between ONTOCHAIN
and other blockchain ecosystems.
3. ONTOCHAIN INTEROPERABILITY & API
Motivations : Build an ONTOCHAIN client based on Ethereum that is a stable and well tested system for data
transactions and has a cost-effective network for the operation of its applications.
Design suitable schemes to increase the throughput in order to sustain a huge volume of real-world transactions
for the ONTOCHAIN platform
Design more efficient data transmission mechanisms for the ONTOCHAIN services and applications
Finding new approaches on how to store data effectively in the ONTOCHAIN platform with limited resources.
Design new prototypes on how different chains can be linked to each other on a hierarchical/scalable basis.
4. ONTOCHAIN NETWORK DESIGN AND
Motivations : Design and implement prototypes that will provide ontologies management and setup for
decentralized semantic matching of demand and supply for different use case scenarios (e.g., apartments, land,
Support different ambitious use-case scenarios (e.g., apartment rental, car sale, freelancing)
Rely on existing ONTOCHAIN components to provide new services like ontology description, evaluation,
Provide fairness-first solutions, i.e. a marketplace prototype that gives equal power to sellers, buyers and to the
Best tradeoff for decentralized ontology matching for achieving higher throughput
Incorporation of Property Graphs
5. SEMANTIC BASED MARKETPLACE FOR ONTOCHAIN
Motivations : Data provenance metadata helps to provide a detailed picture of how the data was
created/collected, where it was stored and how it was used/modified/transformed.
Support automated checking of data-related transactions against GDPR
Define/adopt ontology for ROPAs
Record business processes, especially for supply chain management
Automated verification of rule compliance in business processes
