A Survey on Blockchain-Based Telecommunication Services Marketplaces

Abstract

Digital marketplaces were created recently to accelerate the delivery of applications and services to customers. Their appealing feature is to activate and dynamize the demand, supply, and development of digital goods, applications, or services.By being an intermediary between producer and consumer, the primary business model for a marketplace is to charge the producer with a commission on the amount paid by the consumer. However, most of the time, the commission is dictated by the marketplace facilitator itself and creates an imbalance in value distribution, where producer and consumer sides suffer monetarily. In order to eliminate the need for a centralized entity between the producer and consumer, a blockchain-based decentralized digital marketplace concept was introduced. It provides marketplace actors with the tools to perform business transactions in a trusted manner and without the need for an intermediary.In this work, we provide a survey on Telecommunication Services Marketplaces (TSMs) which employ blockchain technology as the main trust enabling entity in order to avoid any intermediaries. We provide an overview of scientific and industrial proposals on the blockchain-based online digital marketplaces at large, and TSMs in particular. We consider in this study the notion of telecommunication services as any service enabling the capability for information transfer and, increasingly, information processing provided to a group of users by a telecommunications system. We discuss the main standardization activities around the concepts of TSMs and provide particular use-cases for the TSM business transactions such as SLA settlement. Also, we provide insights into the main foundational services provided by the TSM, as well as a survey of the scientific and industrial proposals for such services. Finally, a prospect for future developments is given.

Regulatory Data Privacy Concerns in Proliferating IoT Era of Telecommunication Data Monetization: A Systematic Literature Review

“…Currently, the use of blockchain and smart contracts in 5G IoT ecosystems is a popular area of research for driving data monetization. However, to ensure trustworthy, privacypreserving and automated business settlements and collaborations between Telcos, organisations such as the European Telecommunications Standards Institute (ETSI) and Global System for Mobile Communications (GSMA) are enforcing smart contracts in federated marketplaces [80]. It is recommended that further research be conducted in collaboration with these organisations to address the legitimacy of data propertisation in blockchain-enabled data marketplaces.…”

Technological Transformation of Telco Operators towards Seamless IoT Edge-Cloud Continuum

“…Blockchain in telecommunication networks gain high popularity with the hype. The research heavily focuses on the usage of blockchain in marketplaces [ 20 ], network sharing [ 21 ], infrastructure sharing [ 19 , 22 ], bandwidth sharing [ 23 ] and usage of AI in IoT [ 24 ]. Summarizing the benefits of blockchain in telecommunications, we see the following merits: decentralized, tamper-resistant, traceable, anonymity-preserving and transparent.…”
