Abstract: Blockchain is a technology used to immutably and transparently store information that has gained wide popularity due to the use with cryptocurrency, but it is suitable for many other business scenarios. In this paper, the authors deal with carriers providing voice services by exchanging calls with each other. These companies need to transparently store call detail records (CDR) in order to avoid billing discrepancies which can lead to disputes and risk of interruption of services with heavy consequences from the legal point of view. In this paper, the authors present a solution to this problem by using hyperledger fabric to develop smart contracts, which are invoked to store information about each CDR generated. The proposed solution initially stores CDRs before inputting these to the blockchain network. The paper presents experiments with thorough testing on the blockchain network and also some performance improvements. Results show the effectiveness of avoiding disputes by guaranteeing that CDRs are exchanged effectively and immutably without room for ambiguities or misinterpretation.
