In recent years, blockchain technology integration and application has gradually become an important driving force for new technological innovation and industrial transformation. While blockchain technology and applications are developing rapidly, the emerging security risks and obstacles have gradually become prominent. Attackers can still find security issues in blockchain systems and conduct attacks, causing increasing losses from network attacks every year. In response to the current demand for blockchain application securitydetection and assessment in all industries, and the insufficient coverage of existing detection technologies such as smart contract detectiontechnology, this paper proposes a blockchain core technology security assessment system model, and studies the relevant detection and assessment key technologies and systems. A security assessment scheme based on a smart contract and consensus mechanism detection scheme is designed. And the underlying blockchain architecture supports the traceability of detection results using super blockchains. Finally, the functionality and performance of the system were tested, and the test results show that the model and solutions proposed in this paper have good feasibility.

“…The consensus algorithm specifies how data are spreading among all blockchain nodes, how decisions are made by each node, and how the new block of verified transactions is added to the blockchain [50]. For brevity, in this paper, we will not cover all available consensus algorithms, considering that there are already some surveys that describe them in more detail [51]- [54]. Instead, in the next subsection, we briefly compare the most widely adopted consensus algorithms and their suitability for MoT, such as Proof-of-Work (PoW), Proof-of-Stake (PoS), Byzantine Fault Tolerance (BFT) and their corresponding modifications [52].…”

The future of networking will be driven by the current emerging trends of combining the physical and virtual realities in cyberspace. Considering the ambient pandemic challenges, the role of virtual and augmented reality will definitely grow over time by transforming into the paradigm of the Metaverse of Things, where each person, thing or other entity will simultaneously exist within multiple synchronized realities. In this paper, we propose a novel framework for future metaverse applications composed of multiple synchronized data flows from multiple operators through multiple wearable devices and with different quality requirements. A new service quality model is proposed based on a customizable utility function for each individual data flow. The proposed approach is based on dynamic fine-grained data flow allocation and service selection using non-fungible tokens, which can be traded over the blockchain among users and operators in a decentralized mobile network environment.

“…e Proof of Work (PoW) consensus algorithm is used in our approach. e miners keep on trying to create the random nonce until they reach the constraints of the target nonce [22]. Once a miner gets the desired nonce, miner obtains the authority of broadcasting the block as a new block to the distributed blockchain.…”

Cognitive learning is progressively prospering in the field of Internet of Things (IoT). With the advancement in IoT, data generation rate has also increased, whereas issues like performance, attacks on the data, security of the data, and inadequate data resources are yet to be resolved. Recent studies are mostly focusing on the security of the data which can be handled by blockchain. Blockchain technology records the learned data into the block which is generated after completing proper consensus mechanism. In this paper, Hetero Federated Learning approach is used to apply cognitive learning on data produced by Internet of Thing devices. Security on cognitiveIoT data is provided by blockchain using Proof of Work consensus mechanism. By applying blockchain over heteroFL approach, we have conducted various simulations to check the performance of our proposed framework. Parameters taken into consideration during performance evaluation are effect of number of blocks on memory utilization and impact of data sample size on accuracy according to different learning rates.
