Distributed Ledger Technologies for Cellular Networks and Beyond 5G: a survey

Cellular networks have played a critical role in building today’s Internet. However, they are facing more and more challenges such as softwarization and programmability, decentralization, as well as opening to new business models, while keeping a very high level of trust and reliability. DLT (Distributed Ledger Technology) is a promising field to address these challenges in an innovative way. In this paper, we present a comprehensive analysis of DLT applications for cellular networks, covering the Radio Access Network (RAN), Core Network (CN), Applications & services, as well as Inter-actor communication & cooperation.
