Improving Telecom Industry Processes Using Ordered Transactions in Hyperledger Fabric

Abstract

Despite the enormous potential of distributed ledgers such as blockchain to increase revenue and lower costs, telecom firms have been slower than other regulated industries to integrate blockchain into its operations. We examine how three backend tasks currently performed by telecoms (managing roaming agreements, mobile number portability, and inter-carrier settlement) can be accomplished with greater efficiency using ordered transactions in Hyperledger Fabric - a permissioned blockchain framework. We also explore the role of peer types in the ordering process, how these integrate with Raft ordering service, as well as how several peculiarities in telecom can be addressed using chaincode - Fabric's version of smart contracts.
