Funding Allocation per Countries

By rules, the ONTOCHAIN Open Call 1 funds have been distributed to the legal representative of the legal entity or of the consortium. In that last case, a consortium agreement has been signed by the parties belonging to the consortium mentioning the amount shared between them. The figure hereafter shows the funding distribution per countries, taking into account only the legal representative’s countries, as well as only Open Call 1 phase 1. In phase 2 only 6 projects among the 18 selected will remain and will be funded, thus the funding repartition per country might evolve.
