“…Yao Sou et al [30] proposed a more efficient consensus algorithm called SV-PBFT (Shapley Value-PBFT), which simplifies the consensus process, reduces communication overhead, and enhances consensus efficiency. In Riyad et al [31], to address the challenges of high communication overhead and low algorithm efficiency, a practical Byzantine fault tolerance algorithm (S-PBFT) was proposed, tailored to the characteristics of consortium blockchains. This algorithm introduces a node-scoring mechanism, classifying nodes into consensus nodes, candidate nodes, and early-stage nodes.…”

Currently, there are several issues in China’s rural property rights trading, including poor credit reporting, low transaction efficiency, non-standardized transaction contracts, and high costs for rights protection. However, blockchain technology, known for its convenience, security, and traceability, is highly compatible with the requirements of standardization, convenience, and agility in rural property rights trading. Therefore, we propose a system framework for rural property rights trading based on the Hyperledger Fabric consortium blockchain. This framework significantly enhances transaction efficiency, improves the security of rural property rights trading, effectively resolves contract disputes in property rights transactions, and promotes rural revitalization and development. Furthermore, we design the information data structure on the blockchain, present the information flow, and develop smart contracts that utilize automation capabilities to automatically summarize, analyze, and issue alerts based on on-chain data, enabling risk assessment for both buyers and sellers. Additionally, we introduce an improved PBFT consensus algorithm called CA-PBFT, which is based on the PBFT consensus protocol and integrates a scoring model and simplified consensus protocol. CA-PBFT efficiently reduces transaction response latency and improves information throughput. Finally, we develop a prototype system for rural property rights trading and perform a performance comparison and analysis of CA-PBFT against other PBFT-based consensus algorithms in this prototype system. Experimental results demonstrate the feasibility of the prototype system framework for rural property rights trading.

To address the problems of high communication complexity, the random selection of master nodes, and limited supported network size of the Practical Byzantine Fault Tolerance (PBFT) consensus algorithm for consortium chains, an improved Byzantine Fault Tolerance (CBFT) algorithm based on grouping and credit hierarchy is proposed to optimize the nodes of large-scale consortium chains structure. First, the network nodes are divided into different consensus sets according to their response speed to the management nodes, and the consensus is carried out inside and outside the group respectively; based on this, a credit grading mechanism is proposed and a credit calculation formula is introduced to select the management nodes; finally, a simulation and performance testing system based on this improved scheme is built. The experimental results show that CBFT has less communication overhead, shorter latency, and higher throughput than PBFT, and it is more obvious with the increase in the number of nodes, which meets the needs of large consortium chains.

“…Step 2 is data understanding and its objective is to know what can be expected and achieved from this data. All so checks the quality of the data, in several terms, such as data completeness, value distributions, and data governance compliance (Almakki et al, 2022). In these steps, data scientists in the data mining process are covered data mining models, Steps, and challenges involved in the data extraction process., how the current state of the use of full data is and how it should be, in order to be useful to the algorithm and process involved (Mariscal et al, 2010).…”

COVID-19 has greatly disturbed life in many ways and has changed the way we live. Various surveys have been conducted in different fields, and the teaching-learning process has been affected to a great extent. During this pandemic, various online tools and technologies have been available for guiding students without attending school. Many governments, corporations, and research fields have officially ordered to use of online media for the teaching-learning process. Platforms such as Google Meet, Microsoft Team, and Web-e-X have allowed and arranged for online video conferencing mediums to achieve the goal of the teachinglearning process. However, as mentioned above, there are some serious issues with the online teaching-learning process. These include problems with continuous network bandwidth during sessions, physical and mental presence in the class, difficulties handling mathematics classes, and the potential for non-sense activities that may disturb the entire class. In order to discover knowledge, I am using a new approach to data mining technology called CRISP-DM. This study addresses the effectiveness of online teaching mode and learning and the challenges faced by students and teachers who are taking online classes during COVID-19. According to this study, 88.2% of students did not have proper internet or technology facilities, 58.30% of students were not satisfied with online learning, 85.3% of students complained about eyesight issues from taking online classes on devices, and 50.01% of students were unable to manage university affairs.
