As a technology foundation of cryptocurrencies, blockchain enables\ndecentralized peer-to-peer trading through consensus mechanisms without the\ninvolvement of a third party. Blockchain has been regarded as an auspicious\ntechnology for future cellular networks. It is able to provide solutions to\nproblems related to mobile operators and user trust, embedded smart contracts,\nsecurity concerns, pricing (e.g. for roaming), etc. When applying blockchain to\ncellular networks, there are significant challenges in terms of deployment and\napplication, due to resource-constrained transactions. This article begins by\nintroducing the basic concept of blockchain and then moves on to illustrate its\nbenefits and limitations in the roaming system. Two models of roaming-based\nblockchain technologies are offered to show their suitability for cellular\nnetworks as opposed to traditional technology. Finally, potential issues and\nchallenges of roaming-based blockchains are addressed and evaluated using the\nroaming use case in the EU.\n
