Tools that include Internet of Things technology are tools that enable simulation of human performance by tools by embedding multiple stimuli and sensors. But the mechanism of action of these tools has challenges in maintaining the security of private information. The first issue in this regard is the necessity of nature and separation of private data of the non-private type. In the Iranian legal system, the only legal document in this field is Article 58 of Electronic Commerce Law, and the ambiguous text of this article has challenged the identification of this type of data. In this article, for an unknown reason, by separating the types of private data, not only has nature of this data been disrupted, but only a specific category of this data has been subject to the terms of the article for processing and no other provisions have been established. Is. However, in European Union, there are relatively comprehensive regulations in field of identifying the nature of private data, four criteria of identification based on the nature of the data processed, the purposes of using the processed data, concept of nicknamed data and Encrypted data exchanged in decentralized platforms (including China blockchain technology) has been identified as the criterion for identifying this type of data. Application of these criteria by policymakers in Iran could be the solution to many of the challenges ahead.. Manuscript profile -

This mechanism takes place in four forms based on donation, reward, loan and stock, the most common of which is stock-based financing. The main question of the present study is what are the challenges of implementing the collective financing process in a financial system and what can be the role of technology in providing useful solutions to solve these challenges? The present study describes the qualitative research method and the method of collecting documentary information. This mechanism faces three main challenges of transparency, maintaining the security of information exchange and storage, and protecting the privacy of individuals. The solution is to implement decentralized platforms in one country. However, this process requires some legislative and executive policies, including the granting of digital signatures, the validation of virtual currencies and the mechanism for extracting and exchanging these currencies, the adoption of comprehensive laws on the provision of general legal dimensions related to collecting, processing and storing private information and awareness. It's part of the people. In order to explain the mentioned topics, the present study in three speeches first explains the nature of the types of collective financing and its implementation mechanism and then expresses monitoring and support measures, challenges and technological solutions to solve the challenges of implementing this mechanism.

This system consists of a distributed ledger with a chain of blocks that records every network transaction. This ledger is replicated by every node in the network. We require a mechanism that provides consensus for the entire network, known as "consensus algorithm," in order for the state of this ledger to be the same for all nodes of the network at any given time. In this work, we will suggest a novel consensus algorithm that protects the blockchain platform from four common attacks. These attacks include the Sybil, Denial of Service, 51%, and Eclipse attacks. Due to its multiple control parameters, generic and all-purpose character, immunity to different attacks, and acceptable execution speed, our suggested algorithm can be used to build secure blockchain-based systems in a variety of applications.

Therefore, this study seeks to solve the challenges by benefiting from the advantages of blockchain technology, its durability, and relying on IDS architecture based on multi-node cooperation. The proposed model is an intrusion detection engine based on the decision tree algorithm implemented in the nodes of the architecture. The architecture consists of several connected nodes on the blockchain platform. The resulting model and logs are stored on the blockchain platform and cannot be manipulated. In addition to the benefits of using blockchain, reduced occupied memory, the speed, and time of transactions are also improved by blockchain. In this research, several evaluation models have been designed for single-node and multi-node architectures on the blockchain platform. Finally, proof of architecture, possible threats to architecture, and defensive ways are explained. The most important advantages of the proposed scheme are the elimination of the single point of failure, maintaining trust between nodes, and ensuring the integrity of the model, and discovered logs.

This research used survey method using questionnaire tool to collect information and also used structural equation modeling with Partial Least Squares (SEM-PLS) approach for statistical analysis. The findings of this research first develop the theoretical and theoretical relationship between concepts such as perceived value and resistance and secondly examine and study this relationship in the context in which managers and activists of the tourism sector operate. In the first stage, the conceptual model of this research is based on the model presented by Walsh et al [1]. The discussion about the research findings shows that the benefits of substitution in the minds of managers and activists of the tourism sector are much stronger than the costs of substitution of blockchain technology. Also, the simplicity of the infrastructure is one of the key factors that has a high impact on understanding the benefits of replacement as well as the perceived value. Examining the role of perceived functional advantage and perceived image in the formation of alternative benefits is one of the innovations of this research in the research related to the application of blockchain technology in the tourism sector. So it can be concluded that in order to reduce resistance to blockchain technology, managers should emphasize more on the advantages of this technology. Manuscript profile -

The lack of trust in the correctness and non-manipulation of data has caused users' satisfaction to not be provided as it should be. Considering that the existing online scoring system deals with a central server, all score data is stored in a central server; Therefore, all score data can be deleted, changed and manipulated by the system administrator to change the score results in favor of the service or product provider. In this research, the online scoring system using distributed ledger technologies has been introduced as a proposed system to solve all the weaknesses in the current systems. Distributed ledger technologies are a type of technology that works in a decentralized manner and there is no focus from any entity on this technology. There are different types of distributed ledger technologies. Among distributed ledger technologies, block chain technology is chosen for the proposed scoring system due to its smart contract support. In the proposed online scoring system, the performance criteria of a node are unknown and therefore cannot be used directly to optimize the segmentation results. To solve the performance problem caused by the difference of nodes in the blockchain without knowing the different characteristics of the nodes, we propose a new segmentation method called NoRS. This proposed method consists of four phases: NoRS schematic, scoring mechanism, segmentation strategy, transaction confirmation, creation and release of new block. Therefore, by reviewing the transaction process reports, we evaluate the nodes and assign them to different committees based on the score corresponding to each node; With this process, the ratio of different nodes within the committee is balanced to improve the blockchain transaction efficiency. The advantages of the proposed scoring system compared to the existing systems are that the proposed system works in a decentralized manner and the information cannot be manipulated. Also, the privacy of the scorers is preserved and the transparency of the data is guaranteed. Manuscript profile -

Sina Masoumi * Abstract The potential of blockchain technology for sustainable supply chain management is widely acknowledged, yet its implementation encounters several obstacles. This study seeks to analyze the developmental barriers of blockchain technology for sustainable supply chain management in Iran and offer comprehensive strategies to address them. This study contributes to comprehending the barriers to blockchain technology development for sustainable supply chain management in Iran and provides practical recommendations for policymakers and stakeholders. To achieve this, a review of prior studies was conducted to identify 27 significant barriers, which were then categorized into six areas, with their importance calculated using the Base Criteria Method and expert surveys. Subsequently, through interviews with experts in this field, seven comprehensive strategies were proposed to address the acceptance barriers. The COCOSO method was used to prioritize these strategies. A decision matrix was created to gather input from experts, and after collecting questionnaires, the strategies were ranked using COCOSO formulas. The strategies of “Providing an Implementation Roadmap for Blockchain” and “National-Level Strategic Policy for Blockchain Adoption” were ranked as the first and second priorities, respectively. These findings underscore the significance of strategic planning and policy-making in facilitating the adoption of blockchain technology and advancing sustainable supply chain management practices.
