The European Union is looking into creating EU-wide cross-border public services using blockchain technology. To achieve this complex goal, they have established European Blockchain Services Infrastructure and enabled all European blockchain companies to compete to become a part of it. There are three phases in total, and the company has become the finalist participating in the last phase and presenting its product called Relational Blockchain Nebula (RBN). The company demonstrated the potential for Relational Blockchain Nebula (RBN) to address two important use cases: Digital Product Passports and Intellectual Property Rights. Phase 2B is about finalizing the use cases and testing the blockchain to prove that we can become THE blockchain for the EU. It is a chance to become a part of the team building THE blockchain that will be used by millions of Europeans in the future.
