Minimizing Risk of Disputes Among Telecommunication Carriers With Blockchain Technologies

Abstract

In recent years, blockchain technologies are constantly transforming many business processes. A shared, distributed ledger has revolutionized transaction recording, handling trust, and robustness in business network participants. In the telecommunication sector, the primary concern of voice over internet protocol (VoIP) providers when exchanging calls is the transparent storage of call detail records (CDRs) to avoid billing discrepancies, disputes, and interruption of services. In this chapter, the authors aim to investigate the utilization of permissioned blockchain in carriers' business models in telecommunication. They propose a business model architecture based on hyperledger fabric for developing smart contracts, which are invoked to store information about each CDR generated and business cases. The necessary steps and configurations for integrating the different technologies and building a development network are presented. Finally, the performance testing results regarding the latency for a transaction submission are shown.
