3. | ONTOCHAIN.NGI.EU ONTOCHAIN Architecture High-level architecture and building blocks for innovative applications
4. | ONTOCHAIN.NGI.EU ONTOCHAIN Architecture 3-layer architecture OC1 & OC2 innovators provide building blocks for future ONTOCHAIN Applications APPLICATIONS ONTOLOGIES DISTRIBUTED LEDGER INTEROPERABILITY MODULES AND PROTOCOLS 4
5. | ONTOCHAIN.NGI.EU ONTOCHAIN Architecture 3-layer architecture OC1 & OC2 innovators provide building blocks for future ONTOCHAIN Applications APPLICATIONS ONTOLOGIES DISTRIBUTED LEDGER INTEROPERABILITY MODULES AND PROTOCOLS OC1 & OC2 OC3 5
6. | ONTOCHAIN.NGI.EU ONTOCHAIN Architecture 6 3-layer architecture *ADOS
7. | ONTOCHAIN.NGI.EU ONTOCHAIN Pilot Network
8. | ONTOCHAIN.NGI.EU 8 The ONTOCHAIN Pilot Infrastructure Why this pilot network? • Provide a space to deploy the results of the 3 open calls • Test individual results/features • Validate integration and performance of the ecosystem • Prepare for commercial exploitation
9. | ONTOCHAIN.NGI.EU The ONTOCHAIN Pilot Infrastructure Timeline Sept. 2020 ONTOCHAIN kickoff Sept. 2023 ONTOCHAIN ends Exploitation starts May 2022 ONTOCHAIN pilot deployed Demonstrations & experiments Summer 2023 Lessons learned & adaptations
10. | ONTOCHAIN.NGI.EU OC1 & OC2 projects stats Over 50% of the projects funded in OC1 and OC2 use the EVM
11. | ONTOCHAIN.NGI.EU 11 The ONTOCHAIN Pilot Infrastructure Network specification Sidechain name Bellecour Type EVM compatible chain Consensus AuRa Proof of Authority (PoA) Bridged to Mainnet Block time 5 seconds Tx fees (Gas price) None (zero) Visibility Public Explorer https://blockscout-bellecour.iex.ec/ Trustable Fast No fees Energy efficient
12. | ONTOCHAIN.NGI.EU The ONTOCHAIN Pilot Infrastructure Network specification (cont.) Metric Value Block time 5 seconds Duration to produce a new block Block size 6,700,000 gas (exp: transfer txs costs 21000) Number of transactions per block Gas price 0 Transaction fees amount Token RLC ERC-20 compliant Validators 8 Block producers in the chain. Access nodes 2 Entry points to the chain Bootnodes 4 Discovery nodes
13. | ONTOCHAIN.NGI.EU 13 ONTOCHAIN infrastructure Network nodes 8 validators & 8 fullnodes: • iExec (France) • University of Ljubljana (Slovenia) • University of Athens (Greece) • IntelliSemantic (Italy)
14. | ONTOCHAIN.NGI.EU 14 ONTOCHAIN infrastructure Network usage • Smart contracts deployment limited to whitelisted users (any OC1, 2 and 3 team can ask to be whitelisted). • OpenEthereum client • Node monitoring: https://netstat-bellecour.iex.ec/ • Explorer: https://blockscout-bellecour.iex.ec/
15. | ONTOCHAIN.NGI.EU 15 ONTOCHAIN infrastructure Network expansion and sustainability Will the network grow? ➜ Yes, according to the final business model How? ➜ It is too early to say at this time: will depend on the business model and on the lessons learned from the pilot!
16. | ONTOCHAIN.NGI.EU 16 Conclusions Watch presentations from OC1 & OC2 projects today and tomorrow: • KnowledgeX • DKG • ADOS • DESMO-LD • CopyRightLY • REPUTABLE • CARECHAIN • MFSSIA • BOWLER • Ontospace • PiSwap Don’t miss the presentation of OC3 this afternoon!
