Abstract Blockchain technology is increasingly pervasive in social production and life, and its influence on the accounting and auditing industry is undeniable. The article extensively researches blockchain technology and smart contracts, and it constructs a blockchain-based cloud data auditing model. Combining it with the evolutionary game model completes the construction of the blockchain-based cloud data auditing system. The running cost of the auditing model is analyzed in terms of communication and computation overhead, smart contract cost, time cost, etc., and how it affects the strategies of auditing clients and auditors is studied from the aspects of cost and benefit, respectively. In this paper, the audit model’s average communication overhead and computation overhead are 9.86 KB and 0.82 seconds, respectively. The cost of the smart contract model is relatively low and shows a steady trend. The average query time of this paper’s auditing model is 0.78ms, and none of the validation times on the validator exceeds 5ms, while the average validation times on the blockchain and cloud servers are 11.01ms and 534.35ms, respectively. The auditing client and the auditor tend to adopt the blockchain technology strategy when the cost reduces, or the benefit increases, with a probability of adoption approaching 1 after numerous games.

ABSTRACT: It is widely held that smart contracts on a blockchain possess several unique properties, including immutability, disintermediation, and enhanced security, that can be advantageous to organizations. In particular, having these properties can enable smart contracts to benefit human resources departments in a number of ways, including applicant verification, tracking employee skills and tasks, and facilitating compensation. However, it is also reported that effectively implementing smart contracts involves a number of challenges to HR managers. To address these challenges, it would be valuable to establish criteria to help HR managers employ smart contracts successfully. The purpose of this paper is to develop a set of such criteria. The paper first provides an overview of the nature of blockchain and smart contracts and then, based on a review of relevant literature, describes how implementation of blockchain-enabled smart contracts in an HR department may benefit an organization by producing transaction cost savings through expediting processes, enhancing security, and reducing intermediaries. The paper then focuses on various challenges that have been identified in the literature to the successful use of smart contracts. These include issues regarding smart contract integrity, immutability, and security, as well as potential problems associated with a variety of legal issues. Synthesizing this information, the paper develops a set of best practice guidelines to help HR managers determine whether and how to employ smart contracts successfully for HR-related processes. The guidelines emphasize the importance of initial understanding and testing of planned smart contracts, protecting security by ensuring that only permissioned people can access smart contract data, and guaranteeing the integrity of smart contracts by paying very close attention to the translation of natural to programming language and establishing robust reviews of programmed contracts. Policy implications of the guidelines include the importance of HR departments ensuring that all employees who are involved in implementing the technology have a good understanding of the nature and capabilities of smart contracts, that robust methods be implemented to guarantee that the contracts are correctly programmed, and that HR managers keep abreast of legislative environment related to legal issues that may affect their department’s use of smart contracts.

In response to global efforts to deal with climate change, various renewable energy policies are being implemented. Among these, renewable portfolio standards (RPS) and renewable energy 100 (RE100) regulate the obligated supply of renewable energy to ensure compliance with set quotas by nations and institutions. In this context, the renewable energy certificate (REC) system is employed to assist obligated entities in meeting their renewable energy generation quotas. Obligated entities can purchase REC from renewable energy generators to obtain recognition for their renewable energy allocation. However, the current REC system is insufficient in addressing issues related to procedural complexity and cyber security. This study aims to overcome its limitations by applying the blockchain technology. Blockchain, a distributed financial network, serves as a digital ledger, enabling peer-to-peer transactions in a simple, transparent, and secure way. The proposed new REC system based on blockchain moves away from the complex structure of the traditional REC system, simplifying the system into four processes: participation, issuance, transaction, and authentication. Moreover, by applying blockchain algorithms, it addresses the cyber security issues of the traditional system. The case study using Hyperledger Besu, or one of blockchain platforms, demonstrates that the aspects of procedural complexity and cyber security are improved in the proposed system.

The article uses the ARDL model to study the impact of the VIX index and the indices of economic and market uncertainty based on data from the social network X (formerly Twitter, blocked in the Russian Federation) on the volatility of Bitcoin. To estimate the unobservable cryptocurrency volatility, the author uses a nonparametric estimator derived from 5-minute data on Bitcoin closing prices, considering adjustments if there are gaps within the day. The paper considers the data for the period from 02.01.2018 to 30.12.2022, divided into two half-periods: pre-COVID-19 period (from 02.01.2018 to 28.02.2020) and post-COVID-19 period (from 01.03.2020 to 31.12.2022). According to the results obtained by estimating the ARDL model at different half-periods, in the long term, there is a significant negative VIX index impact on the realized volatility of Bitcoin. This paper observed a short-term (instantaneous) significant positive effect on the realized volatility of Bitcoin for the index of market uncertainty TMU_ENG in the pre-COVID-19 period. The identified significant effects make it possible to use the VIX and TMU_ENG indices to improve the forecast quality in models for the volatility of the Bitcoin cryptocurrency.

With the acceleration of global integration and the rapid development of technology, economic cooperation and regional integration have become an undeniable force in today's world development. Especially with the implementation of the "the Belt and Road" strategy, this development trend is more obvious. This plan was launched by China in 2013 with the aim of promoting infrastructure construction, trade cooperation, cultural exchanges, common development, and regional cooperation in Asia, Europe, Africa, and other regions. With the rapid development of Internet, big data, artificial intelligence and other technologies, the digital economy has become an important driving force for the development of the world economy. It has not only changed the operation mode of traditional industries, but also spawned new industrial forms. However, in a network environment lacking trust, trustworthy communication of data is an important prerequisite for promoting active data sharing among network entities. Information security technology based on encryption technology can effectively solve problems such as data untrustworthiness and privacy leakage in information exchange. This paper focused on the trusted exchange of data in the "the Belt and Road" digital economic cooperation, and discussed how to solve the trust problem in data exchange with the help of blockchain smart contract technology. First, the background of the "the Belt and Road" initiative and the significance of digital economy development were briefly introduced. Subsequently, the challenges faced by trusted data exchange in a network environment lacking trust were analyzed, and a solution based on blockchain smart contracts was introduced. The experimental results showed that when the data block size was 1GB, the data trusted exchange system based on blockchain technology took 10 seconds, and the data transmission rate still reached 891Mbps.

The conceptual foundations of artificial intelligence and blockchain technology are considered. Methodologically, the work is based on the use of the analysis method to identify the limitations and prospects of the synergistic development of blockchain technologies and artificial intelligence in the conditions of the digital transformation of the economy; an empirical method for collecting and processing information about the features and trends in the development of the researched technologies; graphical method for visualizing the structural characteristics of an artificial neural network and the dynamics of the growth of computing power of the blockchain network. The key historical obstacles to the development of artificial intelligence technology are analyzed, which include limitations of computing power, information limitations, and methodological problems. It was found that overcoming the problem of limiting computing power in connection with similar requirements for the hardware base contributed to the synergistic interaction of blockchain technology and artificial intelligence. It is shown that a promising aspect of the synergy of artificial intelligence and blockchain technologies in the context of the use of computing power is related to the idea of ​​using the computing power of miners to solve problems that have an independent value, in particular, the training of artificial neural networks. The key trends of the digital transformation of the economy, for which the key determinant is the synergy of blockchain and artificial intelligence, are the Internet of Things, the sharing economy, as well as inclusion and sustainable development. The synergistic effect of artificial intelligence and blockchain technology in the field of the IoT is that artificial intelligence makes it possible to bring the degree of "intelligence" of devices to a qualitatively new level, endowing them with the ability to make autonomous decisions and adaptive behavior. And blockchain technology is able to neutralize a significant part of the threats in the field of IoT, in particular, those associated with increasing autonomy of smart devices. The role of artificial intelligence in the development of the sharing economy is to optimize the recommendations of digital platforms regarding the exchange of resources or access to them, which leads to an increase in the effectiveness of the decisions making, an increase in consumer satisfaction, and has a positive effect on the operational results of the platforms themselves. Blockchain technologies, which are actively used by digital platforms of the sharing economy, increase the safety and reliability of the functioning of these platforms. The synergy between blockchain and artificial intelligence is important given the role they play in enabling inclusion and sustainable development. Their importance in ensuring inclusion is due to the fact that they facilitate the involvement of a wider range of stakeholders in the decision-making process and the redistribution of value through decentralized organizations (DAOs). This ensures the formation of an effective business model, which promotes the activation of the role of small and medium-sized enterprises and the emergence of an effective alternative to the trend of global capital concentration and the dominance of transnational corporations.

Managing smart contracts in an Agile software development based on blockchain technology enables project managers to offer rules for software processes to meet the needs and expectations of stakeholders. On the one hand, smart contracts’ faster cycle time, lower fraud, and lower fees and charges have ensured that the business logic satisfies the stakeholder’s criteria. Agile approaches, on the other hand, are development processes that use incremental and iterative engineering methodologies to drive the system life cycle. Such methodologies are typically well-suited for incorporating and adapting management ideas early in the development life cycle. To reconcile both viewpoints, this work provides an organization modeling for constructing smart contracts on the blockchain utilizing organizational modeling techniques that allow all processes as well as the smart contracts management discipline in supply chain finance system development to be illustrated.
