A patent registration and trading system based on blockchain

In response to the shortcomings of the consensus algorithm for intellectual property transactions, such as high communication overhead, random primary node selection, and prolonged consensus time, a Practical Byzantine Fault Tolerance (PBFT) improvement algorithm based on Divisive Analysis (DIANA) D-PBFT algorithm is proposed. Firstly, the algorithm adopts the hierarchical clustering mechanism of DIANA to cluster nodes based on similarity, enhancing node partition accuracy and reducing the number of participating consensus nodes. Secondly, it designs a reward and punishment system based on node ranking, to achieve consistency between node status and permissions, timely evaluation, and feedback on node behaviours, thereby enhancing node enthusiasm. Then, the election method of the primary node is improved by constructing proxy and alternate nodes and adopting a majority voting strategy to achieve the selection and reliability of the primary node. Finally, the consistency protocol is optimised to perform consensus once within the cluster and once between all primary nodes, to ensure the accuracy of the consensus results. Experimental results demonstrate that the D-PBFT algorithm shows a better performance, in terms of communication complexity, throughput, and latency.

In the aviation industry, the issuance of airside passes often encounters significant delays, posing logistical challenges and hindering crucial operations. This study delves into the potential of implementing blockchain technology, particularly smart contracts, to streamline and expedite airport security processes. Our analysis of data from leading UK airports reveals notable inefficiencies in the current airside pass issuance procedures, necessitating a transformative solution. We advocate for the integration of blockchain smart contracts as a pioneering approach to substantially reduce processing times. By automating execution based on predefined conditions, smart contracts have the potential to revolutionize airport security operations. This research signifies a groundbreaking advancement in the use of smart contracts within the airline industry, underscoring the substantial efficiency improvements that can be achieved. As we conclude this study, we foresee further research and practical implementations to unlock the full transformative impact of blockchain technology on aviation security.

“…In the present day, many researchers and developers have presented blockchain-based solutions to address specific domains, such as a decentralized software repository [2], a meteorological data service [3], a decentralized virus database [4], or a patent registration and trading system [5]. However, to the best of our knowledge, no one has yet presented a solution that serves as a configurable foundation for the development of such domainspecific applications.…”

In today’s highly competitive landscape, effective information sharing is crucial for distinguishing successful entities from the rest. However, achieving seamless collaboration in this digital era remains challenging due to distrust among entities and the absence of a secure data exchange medium. These limitations hinder interactions, reducing competitiveness, especially for resource-constrained entities. To address these challenges, we introduce the Blockchain-based Record and Interoperability Network (BRAIN), a modular framework utilizing blockchain technology. BRAIN offers an innovative solution to foster collaboration, trust, and competitiveness. By leveraging blockchain’s cryptographic techniques, it ensures secure and transparent data exchange, eliminating the need for intermediaries and thereby enhancing productivity and collaboration. BRAIN serves as a configurable foundation for domain-specific applications. BRAIN’s key features include flexibility, efficiency, security, robustness, and scalability. It adapts to diverse applications, integrates seamlessly with existing systems, and ensures secure information sharing. In conclusion, BRAIN provides a foundational platform for entities to assert data ownership and grant access permission. Built on blockchain technology, it offers access traceability and data security and eliminates the need for trusted third parties. Its flexibility and scalability make it a valuable tool for enhancing data sharing. Future enhancements aim to address weaknesses and expand its use cases, promising a robust and versatile solution for secure and efficient data exchange.
