Blockchain Technology: Emerging Applications and Use Cases for Secure and Trustworthy Smart Systems

A medical center in the smart cities of the future needs data security and confidentiality to treat patients accurately. One mechanism for sending medical data is to send information to other medical centers without preserving confidentiality. This method is not impressive because in treating people, the privacy of medical information is a principle. In the proposed framework, the opinion of experts from other medical centers for the treatment of patients is received and consider the best therapy. The proposed method has two layers. In the first layer, data transmission uses blockchain. In the second layer, blocks related to patients’ records analyze by machine learning methods. Patient records place in a block of the blockchain. Block of patient sends to other medical centers. Each treatment center can recommend the proposed type of treatment and blockchain attachment and send it to all nodes and treatment centers. Each medical center receiving data of the patients, then predicts the treatment using data mining methods. Sending medical data between medical centers with blockchain and maintaining confidentiality is one of the innovations of this article. The proposed method is a binary version of the HHO algorithm for feature selection. Another innovation of this research is the use of majority voting learning in diagnosing the type of disease in medical centers. Implementation of the proposed system shows that the blockchain preserves data confidentiality of about 100%. The reliability and reliability of the proposed framework are much higher than the centralized method. The result shows that the accuracy, sensitivity, and precision of the proposed method for diagnosing heart disease are 92.75%, 92.15%, and 95.69%, respectively. The proposed method has a lower error in diagnosing heart disease from ANN, SVM, DT, RF, AdaBoost, and BN.

“…Last but not least are problems associated with coercion and vote-buying. Online voting brings these problems to the next level: As ballots are cast remotely from an uncontrolled environment, coercers and vote buyers can operate on a large scale [ 49 ]. That is why one of the desired properties of an online voting system is coercion resistance.…”

Online voting is a trend that is gaining momentum in modern society. It has great potential to decrease organizational costs and increase voter turnout. It eliminates the need to print ballot papers or open polling stations—voters can vote from wherever there is an Internet connection. Despite these benefits, online voting solutions are viewed with a great deal of caution because they introduce new threats. A single vulnerability can lead to large-scale manipulations of votes. Electronic voting systems must be legitimate, accurate, safe, and convenient when used for elections. Nonetheless, adoption may be limited by potential problems associated with electronic voting systems. Blockchain technology came into the ground to overcome these issues and offers decentralized nodes for electronic voting and is used to produce electronic voting systems mainly because of their end-to-end verification advantages. This technology is a beautiful replacement for traditional electronic voting solutions with distributed, non-repudiation, and security protection characteristics. The following article gives an overview of electronic voting systems based on blockchain technology. The main goal of this analysis was to examine the current status of blockchain-based voting research and online voting systems and any related difficulties to predict future developments. This study provides a conceptual description of the intended blockchain-based electronic voting application and an introduction to the fundamental structure and characteristics of the blockchain in connection to electronic voting. As a consequence of this study, it was discovered that blockchain systems may help solve some of the issues that now plague election systems. On the other hand, the most often mentioned issues in blockchain applications are privacy protection and transaction speed. For a sustainable blockchain-based electronic voting system, the security of remote participation must be viable, and for scalability, transaction speed must be addressed. Due to these concerns, it was determined that the existing frameworks need to be improved to be utilized in voting systems.

The object of research is software for financial accounting and distribution of funds in a non-profit charitable foundation using smart contracts of the Ethereum platform. The work is aimed at designing and implementing a software application for a charitable foundation, which allows to exclude the misuse of funds of a non-profit charitable foundation. The paper proposes an implementation of the Ethereum smart contract for the software of a charitable foundation. In the app, users can apply for financial aid or make a charitable donation. The request for financial support is confirmed by administrators to avoid abuse by those seeking help. Anyone who has a crypto wallet can become a sponsor by transferring funds from its account to a selected request. The sponsor remains incognito when making a charitable contribution. After collecting the entire declared amount, the funds are automatically transferred to the crypto wallet of the request’s owner. A smart contract and a corresponding decentralized web application for interacting with it were experimentally deployed, and their joint work was tested. To implement the smart contract, the Solidity programming language was chosen; developed smart contract converted to bytecode using remix. The resulting bytecode is ready to be deployed on the Ethereum platform. Decentralized web application for interacting with the contract is implemented using Web3.js, Vue.js. A rough estimate of the cost of deploying a project on the Ethereum platform has been made. The deployment and operation of smart contracts and web applications comes with a certain overhead, which is most dependent on the cost of ether. However, this is a justified price to pay for the transparency of transactions and the shadowing of the turnover of funds of the charitable foundation. The results of the research can be used as a basis for further transformation into full-fledged software with the ability to submit all reporting documents to the relevant government agencies and sponsors.
