Until now, every evolution of communication standard was driven by the need for providing high-speed connectivity to the end-user. However, 5G marks a radical shift from this focus as 5G and beyond networks are being designed to be future-proof by catering to diverse requirements of several use cases. These requirements include Ultra-Reliable Low Latency Communications, Massive Machine-Type Communications and Enhanced Mobile Broadband. To realize such features in 5G and beyond, there is a need to rethink how current cellular networks are deployed because designing new radio access technologies and utilizing the new spectrum are not enough. Several technologies, such as software-defined networking, network function virtualization, machine learning and cloud computing, are being integrated into the 5G networks to fulfil the need for diverse requirements. These technologies, however, give rise to several challenges associated with decentralization, transparency, interoperability, privacy and security. To address these issues, Blockchain has emerged as a potential solution due to its capabilities such as transparency, data encryption, auditability, immutability and distributed architecture. In this paper, we review the state-of-art application of Blockchain in 5G network and explore how it can facilitate enabling technologies of 5G and beyond to enable various services at the front-haul, edge and the core. Based on the review, we present a taxonomy of Blockchain application in 5G networks and discuss several issues that can be solved using Blockchain integration. We then present various field-trials and Proof of concept that are using Blockchain to address the challenges faced in the current 5G deployment. Finally, we discuss various challenges that need to be addressed to realize the full potential of Blockchain in beyond 5G networks. The survey presents a broad range of ideas related to Blockchain integration in 5G and beyond networks that address issues such as interoperability, security, mobility, resource allocation, resource sharing and management, energy efficiency and other desirable features.

“…Approaches based on Distributed Ledger Technologies (DLTs) have recently been proposed as a promising way to enhance the coordination between collaborators for detection and mitigation of security incidents. Indicatively, Malomo et al (2018) propose a federation, whereby monitoring data are exchanged to collaboratively detect network anomalies. The federation is based on a permissioned blockchain framework that ensures transparency and business regulation.…”

Network providers either attempt to handle massive distributed denial-of-service attacks themselves or redirect traffic to third-party scrubbing centers. If providers adopt the first option, it is sensible to counter such attacks in their infancy via provider collaborations deploying distributed security mechanisms across multiple domains in an attack path. This motivated our work presented in this paper. Specifically, we investigate the establishment of trusted federations among adjacent and disjoint network domains, that is, autonomous systems (ASes) that collectively mitigate malicious traffic. Our approach is based on Distributed Ledger Technologies for signaling, coordination, and orchestration of a collaborative mitigation schema via appropriate blockchain-based smart contracts. Reputation scores are used to rank ASes based on their mitigation track record. The allocation of defense resources across multiple collaborators is modeled as a combinatorial optimization problem considering reputation scores and network flow weights. Malicious flows are mitigated using programmable network data paths within the eXpress Data Path (XDP) framework; this enables operators with enhanced packet processing throughput and advanced filtering flexibility. Our schema was implemented in a proof-of-concept prototype and tested under realistic network conditions.

“…With the passage of the time security solutions are advancing to fight with the risks and malicious attacks compare to the traditional sources of security. Like blockchain technology, which reduces breach detection gap with the help of continuously monitoring and network traffics against cyber-attacks (Malomo et al, 2018). So, this minimizing of the breach detection gap for cyber-attacks is a big achievement of blockchain technology.…”

“…It doesn't demand any mediator to look after the transaction. This database technology is used by its users that grants them a trustable platform for transacting valuable assets without requiring a centralized authority (Hawlitschek, et al 2018;Malomo, et al 2018). Hence, blockchain technology has the potential to substitute conventional banking practice, making the business more cost-effective and trustworthy.…”

The blockchain technology has given a new shape to the world and disrupted a wide variety of technology-based industries. The disruptive characteristics of blockchain technology have molded the way of doing things. Since the importance of blockchain technology in business and social environment is increasing day by day, this study aimed to underline risks of blockchain technology within the network. Two strategies were made to infer the technology-based risk in the blockchain ecosystem. First, the study examined to find the technology-based risk at the point where a user executes the transaction from his/her computer ‘Node’. Second, this study attempts to figure out the security concerns within the web of the blockchain. After assessment of benefits and risks of this technology, this study concluded with the findings that blockchain is very much secure and trustable system which provides peer-to-peer transactions without needing any trusted third party, besides, once the information of the transaction is recorded, the system stores multiple copies of it, so there is no chance to change or delete it from the system. In the case of negligence, there is a possibility of forgery at the node, but numerous software has been developed for protecting the computer. The approach of the study is grounded in the literature review of journal articles, reports, and conference proceedings from authenticated sources via content analysis of the keywords such as blockchain, security, trust, technology-based risks. Blockchain technology is not associated with finance but it has high usage in other areas like health, education, supply chain, the music industry and many more to explore.
