Abstract

Abstract Since the success of Bitcoin, there have been increased focus of studying the application of blockchain in a broad range of applications, such as in solutions facilitating identity privacy and transaction security using a decentralized architecture via different consensus mechanisms (e.g. proof-of-work) between different geo-located IoT devices/nodes in our increasingly digitalized society (e.g. smart city). In this paper, we survey the usage of blockchain technology for smart communities, focusing on key components of the blockchain applications. We also study the various process models used in the execution of secure transactions. Specifically, we present a detailed taxonomy on the applications, process models used, and communication infrastructure support needed to execute various applications.

  • The rapid expansion of 5G wireless services in scale, speed, and capacity poses new security challenges such as network reliability, data immutability, and privacy.

    “However, the rapid surge and breakneck expansion of 5G wireless services in terms of scale, speed, and capacity also pose new security challenges such as network reliability, data immutability, privacy [4] that must be considered and solved before wide deployments.”
  • Reviewing state-of-art literature, blockchain has mainly cooperated with key 5G enabling technologies including cloud computing, edge computing, Software Defined Networks, Network Function Virtualization, Network Slicing, and D2D communication.

    “Reviewing state-of-art literature works [1], [3], [4], we found that blockchain has mainly cooperated with the key 5G enabling technologies including cloud computing, edge computing, Software Defined Networks, Network Function Virtualization, Network Slicing, and D2D communication.”
  • The blue cluster revolves around the potentials of blockchain solutions for smart communities, energy trading, transportation, artificial intelligence, and construction.

    “Furthermore, the blue cluster revolves around the potentials of blockchain solutions for smart communities (Aggarwal et al. 2019), energy trading (Chaudhary et al. 2019; Jindal et al. 2019), transportation (Astarita et al. 2020; Mehta et al. 2020; Sharma and Park 2018), artificial intelligence (Singh et al. 2019, 2020a, b), and construction (Sun and Zhang 2020).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
