  3. | ONTOCHAIN.NGI.EU 3 3 ONTOCHAIN APPROACH 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 (shared conceptualisation) on one hand as well as on the other hand by the decentralisation and data immutability (shared ledger) ONTOCHAIN

  8. | ONTOCHAIN.NGI.EU OPEN CALL 2: THE 13 PROJECTS ENGAGED 8

    Project Goals Feature supported ADOS To apply blockchain technologies to IoT (Internet of Things) systems, as current IoT systems can be lacking in certain key network aspects such as scalability, security, resource consumption and trustworthiness. Distributed Data Oracles Bowler To make a low-code, end-to-end, web-based IDE that will enable those which are not very familiar with Smart Contracts to learn how to program dApps. Ontochain IDE for app development CareChain To make a platform for issuing microinsurances and compensation if conditions are met using Smart Contracts. Smart Contracts are encrypted and public, so no one can deny part-taking in the process. Automated agreement compliance checking DESMO-LD To design and implement a trustful Oracle prototype and provide the necessary data for its operation. It uses Smart Contracts to gather off-chain data through oracles. IoT data oracle extracting Web of Thing (WoT) Thing Descriptions DKG To make a decentralised knowledge sharing platform using the ONTOCHAIN support. Decentralized Knowledge Management GEONTOLOGY To make a geo-aware protocol for enabling cross-border operations and data exchange in a digital economy. Its main goal is to provide geolocation data to any transaction using smart contracts. Proof of location MFSSIA to create a multi-factor authentication service via blockchain. Blockchain is used MF Identification
  9. | ONTOCHAIN.NGI.EU OPEN CALL 2: THE 13 PROJECTS ENGAGED 9

    Project Goals Feature supported NFTWATCH To collect and aggregate information about NTF's and its marketplaces. It can be used to analyse either on or off-chain data. NFT semantics extraction ONTOSPACE To expand on GraphChain's project to enable networks to emerge. It will provide all necessary building blocks to make the deployment of the ecosystem as easy as possible with graph databases. Trustworthy metadata creation PERUN X to create a framework for transactions between different blockchains that can be performed at minimal cost. It can also be used to execute code on a specific channel, leading to potentially cross-chain contracts. Cross-chain interoperability NFTSWAP to solve the current problem of NFT markets with enabling crowdsended markets (independence of primary and secondary markets), building decentralised price (enabling margin trading- short/long, mechanism to determine price) and providing automated liquidity (similar to UniSwap). NFT pricing PRINGO to make a mechanism for funding charitable causes via blockchain. It provides a direct link from common goods to companies/charities. NFT minting in games for public goods PS-SDA to make a platform for human-centric data management. It enables data to be encrypted on the chain and not accessed by everyone. It Data provenance
