“…Also, authors in [161], [162] investigated the impact of timers and forks on transaction confirmation delay in a wireless system, in particular IEEE 802.11ax. Finally, the authors in [163] attempted to reduce the confirmation delay by weighting nodes based on their feedback speed, then forming a multicast tree and selecting only subsets with quick feedback to participate in block confirmation. • Transaction Loss Probability: This metric records the ratio of failure events to append transactions into the BC.…”

<p>Fifth-generation and beyond (5G and xG) wireless networks are envisioned to meet the requirements of vertical applications like high traffic throughput, ultra-massive connectivity, extremely low latency, and high quality of service. Disruptive technologies, such as massive multiple-input multiple-output, millimeter wave, and multiple access are being deployed to meet these requirements. However, their deployment poses several challenges, including a lack of network transparency, management decentralization, and reliability. Moreover, the heterogeneity of future networks raises security concerns, e.g., confidentiality, privacy, and trustworthiness. Indeed, due to the emergence of novel paradigms, e.g., quantum computing, traditional security approaches are no longer sufficient to protect over-the-air communications. Hence, 5G/xG networks must consider smart security techniques to operate seamlessly and efficiently. Within this context, physical layer security (PLS) and blockchain represent promising solutions to complement existing methods. By exploiting the characteristics of wireless links, PLS can enhance the security of communications, while blockchain may enable networks' decentralization, integrity, and trustworthiness. Motivated by these advancements, we provide an in-depth review of the existing PLS and blockchain literature. Then, for the first time in the literature, we present a framework to integrate PLS with blockchain in 5G/xG systems. We first provide a thorough discussion about the potential of PLS and blockchain for 5G/xG systems. Then, we present our vision of a cross-layer architecture that leverages PLS and blockchain. Through a case study, we demonstrate the high potential of cross-layer design to improve the security of vehicular networks. Finally, we identify related challenges and shed light on future research directions.</p>

“…When the time window expires, the winner is selected according to the specified rule, i.e., block generation time and the number of receipts within the block. Long et al [15] optimized the block propagation in wireless blockchain networks by the partial engagement of nodes and optimal transmission routing based on a distributed Steiner tree. However, since the delay of transaction collection and block propagation is relatively high in MANETs [35], the geographical location of the miner and its connectivity in the network largely affect the blockchain performance.…”

“…The integration of blockchain and MANET improves both MANET security and blockchain adaptability. Nowadays, the blockchain is explored to build on MANETs [6][7][8][9], and its applications involve incentive data collection [10], secure resources sharing [11][12][13], and an expansion of cryptocurrency [14,15]. A MANET-based blockchain is geographically closer to end users than the blockchain based on edge computing, so it is envisioned to provide more safety and privacy protection.…”

Blockchain establishes security and trust in mobile ad hoc networks (MANETs). Due to the decentralized and opportunistic communication characteristics of MANETs, hashgraph consensus is more applicable to the MANET-based blockchain. Sharding scales the consensus further through disjoint nodes in multiple shards simultaneously updating ledgers. However, the dynamic addition and deletion of nodes in a shard pose challenges regarding robustness and efficiency. Particularly, the shard is vulnerable to Sybil attacks and targeted attacks, and dishonest gossip reduces the efficiency of hashgraph consensus. Therefore, we proposed a behavior-based sharding hashgraph scheme. First, dishonest behaviors of nodes are recorded in a decentralized blacklist. Gossip information is sent to a reliable neighbor, and gossip information from another reliable neighbor is received. Second, a tree-assisted inter-sharding consensus is proposed to prevent Sybil attacks. The combination of shard recovery and reconfiguration based on node state is devised to prevent targeted attacks. Finally, we conducted the performance evaluation including security analysis and experimental evaluation to reveal the security and efficiency of the proposed scheme.

“…With the rapid development of blockchain technology, the demand for a higher level of service quality poses a more serious challenge to the design of the blockchain, e.g. the transaction processing performance (Long et al , 2021). Mainstream blockchain platforms, such as Bitcoin, can handle around seven transactions per second (Nakamoto, 2008; Wood, 2014; Sun et al , 2021a).…”

PurposeAs the core technology of blockchain, various consensus mechanisms have emerged to satisfy the demands of different application scenarios. Since determining the security, scalability and other related performance of the blockchain, how to reach consensus efficiently of consensus mechanism is a critical issue in the blockchain.Design/methodology/approachThe paper opted for a research overview on the blockchain consensus mechanism, including the consensus mechanisms' consensus progress, classification and comparison, which are complemented by documentary analysis.FindingsThis survey analyzes solutions for the improvement of consensus mechanisms in blockchain that have been proposed during the last few years and suggests future research directions around consensus mechanisms. First, the authors outline the consensus processes, the advantages and disadvantages of the mainstream consensus mechanisms. Additionally, the consensus mechanisms are subdivided into four types according to their characteristics. Then, the consensus mechanisms are compared and analyzed based on four evaluation criteria. Finally, the authors summarize the representative progress of consensus mechanisms and provide some suggestions on the design of consensus mechanisms to make further advances in this field.Originality/valueThis paper summarizes the future research development of the consensus mechanisms.
