   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

    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!
