Good question. The question emerges: who is in charge when a radio system is disaggregated and reassembled? Because of this, the “big tech” are trying to take control of the RAN networks, which creates another problem, as it misconfigures the new network proposal. One must ask whether there should be a command, or what this standardization should look like. The innovation enabled by 5G network virtualization, along with the standardization and openness driven by the Open Radio Access Network (O-RAN) Alliance, has paved the way for a collaborative future in mobile systems, driven by flexible network sharing. It is natural that scalability and trust issues arise, given the importance of property traceability and the exchange of resources in a shared system. The Blockchain proposal seems quite suitable for bringing trust to open RAN environments. Standardization can come from the ITU, auctions, or market regulation.
