“…Similar solutions may be found in fog computing [77], edge computing [78], and 5G, 6G networks [79], [80]. Viewing the blockchain as a trusted ledger that records all service attributes, a blockchain-based service recommendation system [81] and an auditing solution to protect 5G consumer data [82] are prominent.…”

Service provisioning is of paramount importance as we are now heading for a world of integrated services giving rise to the next generation of service ecosystems. The huge number of service offerings that will be available for customers in future scenarios require a novel approach to service registry and discovery that lets customers choose those offerings that best match their preferences. One way to achieve this is to introduce the provider's reputation, i.e., a quality indicator of the provisioned service, as an additional search criterion. Now, with blockchain technology in our hands, automated regulation of service-level agreements (SLAs) that capture the mutual agreements between all involved parties has regained momentum. In this article, we report our full-fledged work on the conception, design, and construction of a platform for SLA-minded service provisioning called PenChain. With our work, we demonstrate that penalty-aware SLAs of general services -if represented in a machine-readable logic and assisted by distributed ledger technology -are programmatically enforceable. We devise algorithms for ranking services in a search result taking into account the digitized values of the SLAs. We offer scenario-based evaluation of PenChain in the field of precision agriculture and the domain of automotive manufacturing. Furthermore, we examine the scalability and the data security of PenChain for precision agriculture.

Network slicing has gained popularity as a result of the advances in the fifth generation (5G) mobile network. Network slicing facilitates the support of different service types with varying requirements, which brings into light the slicing-aware next generation mobile network architecture. While allowing resource sharing among multiple stakeholders, there is a long list of administrative negotiations among parties that have not established mutual trust. Distributed ledger technology may be a solution to mitigate the above issues by taking its decentralized yet immutable and auditable ledger, which may help to ease administrative negotiations and build mutual trust among multi-stakeholders. There have been many research interests in this direction which focus on handling various problems in network slicing. This paper aims at constructing this area of knowledge by introducing network slice from a standardization point of view to start with, and presenting security, privacy, and trust challenges of network slicing in 5G and beyond networks. Furthermore, this paper covers distributed ledger technologies basics and related approaches that tackle security, privacy, and trust threats in network slicing for 5G and beyond networks. The various proposals proposed in the literature are compared and presented. Lastly, limitations of current work and open challenges are illustrated as well.
