Authors proposed a 4-layer framework that combines
smart cities, smart homes and Internet of Things
devices.
2014 The framework uses smart technologies such as 5G and
AI (Artificial Intelligence).
Marco et al.

In this digital era, mobile networks are connected with
everything like cloud resources, sensors, vehicles and
even robotics. The authors presented use cases and
technologies of 5G networks.
2019 Authors discussed technologies that evolve wireless
networks towards 5G networks. Paper summarizes the
use cases, potentials and main challenges of enabling
technologies.
Nguyen et al.

presented a state of art survey about blockchain for 5G
and beyond networks. Authors explored opportunities
of blockchain in 5G networks and presented extensive
discussions based on literature papers.
2019 Paper also discussed several challenges of integrating
IoT and blockchain and highlighted the motivation to
integrate the 5G network with blockchain.
Liu et al.

Authors proposed Ethereum blockchain-based secure
sharing and data collection framework.
2019 The whole system can provide strong resistance against
database attacks. The system has high security due to
the use of blockchain functionality.
Shen et al.

Authors proposed a privacy-preserving secure support
vector machine (SVM) that is based on blockchain.
2019 The proposed system tackled the issues of data integrity
and data privacy using secure SVM.
WU et al.

Authors developed an Application-Aware Consensus
Management framework to enhance the flexibility
between Internet of Things and Blockchain.
2020 Current static consensus management cannot provide
intelligent configuration capabilities, and the proposed
system resolve this issue.
Hewa et al.

Authors presented a paper about the role of blockchain
in 6G where authors briefly describe challenges, oppor-
tunities, and research directions of integrating 6G
enabled devices with blockchain.
2020 6G wireless networks driven by heterogeneous and
enormous demands of hyper-connected existence of
everything. This article canvassed and highlighted the
blockchain role to mitigate some of the issues.
Alsharif et al.

Authors presented an article that describes the vision,
challenges and potential solutions of 6G wireless net-
works. More specifically, the paper explored the critical
issues and key potential features, including research
activities, key features and vision, challenges and spe-
cific solutions.
2020 The study shows key features and visions at fore-
casting 6G in the following dimensions: intelligence,
energy efficiency, privacy, security, spectral efficiency,
secrecy, affordability, and customization.

In this paper, authors developed a D2C platform
through the combined use of blockchain and federated
learning for Industry 4.0.
2021 Federated learning addresses issues of efficiency and
privacy. Blockchain facilitates poisoning-attack-proof
functionality.

etc. Another important component of a blockchain is smart contract. Smart contracts are programmable applications used to
perform a task based on specific terms and conditions automatically. These smart contracts are similar to traditional contracts,
but instead of running by central authorities, they are programmed to perform the task itself in a decentralized framework. A
