    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

    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!
