Management of traditional construction contracts that is frequently preferred in the architecture, engineering, and construction (AEC) industries are affected by many factors due to the complexity and large number of contract documents.With the introduction of Web 3.0 technology, blockchain is considered as a suitable solution for solving many problems arising from traditional contracts and can be considered as an alternative method to traditional contracts in the AEC industry.Using cryptocurrencies, switching to blockchain-based contracts, and using smart contracts will be advantageous for AEC industry in many ways.However, in addition to these advantages, the existence of risk factors cannot be denied.With this background, this study aims to identify risk factors affecting blockchain-based smart contract use in AEC industry through a comprehensive literature review and to prioritize the identified risk factors using Analytic Hierarchy Process, respectively.The prominent risks were found to include implementation risks, followed by legal risks and contractual risks.The contributions of the study to the academic literature are the identification of the risks that may occur during the integration of blockchain-based contracts into the AEC industry and the diagnosis of any problems that may occur during the integration process.Professionals in the field of construction management can also benefit greatly from the findings of this study by analyzing those risks throughout their projects.

Metaverse comes from a novel released in 1992 entitled “Snow Crash”. Metaverse represents concepts beyond entertainment and commerce to create virtual communities as users use avatars to represent themselves within the Metaverse and interact with other users through avatars. In the Metaverse world, Non- Fungible Tokens, or NFTs for short, are also integrated by registering the ownership of digital assets using blockchain technology. However, with technological progress, there are challenges related to security, regulations, difficulties in using the technology, and others. This challenge causes the NFT market to remain unstable, So it raises crucial questions surrounding the behaviour of an accountant, especially in the Gen Z demographic, on how to face these challenges. For this research regarding Metaverse and NFT, the researchers used the qualitative exploratory method, with interviews being one of the most commonly used for data collection. Concluding this research, the accounting profession still has time to adapt to the changes brought on by the Metaverse and NFTs since the technologies are still a small niche, and the majority of the public does not have access to and knowledge about them. Also, many risks and challenges arise due to inadequate government regulations regarding NFT and Metaverse.

Abstract This study examines blockchain technologies and their pivotal role in the evolving Metaverse, shedding light on topics such as how to invest in cryptocurrency, the mechanics behind crypto mining, and strategies to effectively buy and trade cryptocurrencies. While it contextualises the common queries of "why is crypto crashing?" and "why is crypto down?", the research transcends beyond the frequent market fluctuations to unravel how cryptocurrencies fundamentally work and the step-by-step process on how to create a cryptocurrency. Contrasting existing literature, this comprehensive investigation encompasses both the economic and cybersecurity risks inherent in the blockchain and fintech spheres. Through an interdisciplinary approach, the research transitions from the fundamental principles of fintech investment strategies to the overarching implications of blockchain within the Metaverse. Alongside exploring machine learning potentials in financial sectors and risk assessment methodologies, the study critically assesses whether developed or developing nations are poised to reap greater benefits from these technologies. Moreover, it probes into both enduring and dubious crypto projects, drawing a distinct line between genuine blockchain applications and Ponzi-like schemes. The conclusion resolutely affirms the staying power of blockchain technologies, underlined by a profound exploration of their intrinsic value and a reflective commentary by the author on the potential risks confronting individual investors.

This paper uses transaction-level data across millions of accounts to identify cryptocurrency investors and evaluate how fluctuations in individual crypto wealth affect household consumption, equity investment, and local real estate markets.We estimate an MPC out of unrealized crypto gains that is more than double the MPC out of unrealized equity gains but smaller than the MPC from exogenous cash flow shocks.This MPC is mostly driven by increases in cash/check spending and mortgages.Moreover, households sell crypto to increase both discretionary as well as housing spending.As a result, crypto wealth causes house price appreciation-counties with higher crypto wealth see higher growth in home values following high crypto returns.Our results indicate that cryptocurrencies have substantial spillover effects on the real economy through consumption and investment into other asset classes.

무기한 선물(Perpetual Swaps)은 가상 자산 시장에서만 유일하게 관찰할 수 있는 파생상품으로 2020년 이후 현재 약 20여 곳 이상의 가상 자산 거래소에서 서비스를 제공하고 있으며 2020년 전체 거래 시장의 20.4%, 2021년 50.4%를 차지할 정도로 양적 성장을 이루었다. 본 연구는 거래소 간 비트코인 무기한 선물과 현물(Spot) 간의 가격 차이를 이용해 차익 거래 기회에 대한 실증 분석 결과를 제시한다. 연구 결과, 비트코인 현물과 무기한 선물 가격의 음과 양이 역전 될 때를 거래 진입 및 청산 신호로 인식하는 매매를 통하여 차익 거래 수익을 창출할 수 있음을 확인하였다. 또한 분 단위 거래에서 거래수수료는 차익 거래 수익에 민감하게 작용하였지만, 일 단위 거래에서는 거래 수수료에 민감하지 않은 양의 수익을 보여주었다. 그리고 분 단위 거래에서는 월 평균 9%, 일 단위 거래에서는 월 평균 38%의 높은 수익률을 나타내었다.

Virtual currency movements, which have intensified recently, are in relation to many macroeconomic variables. The decentralized nature of the cryptocurrency market does not eliminate the variables that affect the market. Macro and microeconomic events and variables affect the cryptocurrency market. The cryptocurrency market can also interact with and affect other markets and variables. Indices, which are the indicator indices of the markets, are important in terms of examining the relationship between the markets. The index, which is the indicator of the cryptocurrency market and includes 30 cryptocurrencies, is called the Cryptocurrencies Index (CCi30). The aim of the study is to examine the relationship between the CCi30 index, BIST 100, and Nasdaq Indices. In the study conducted using Granger Causality Analysis, data between the years 2015-2022 were used. According to the analysis result; It was concluded that CCi30 and Nasdaq indices affect each other in a bidirectional way.

More than 12 years have passed since the debut of Bitcoin, the first cryptocurrency, but there is still no clear understanding of the essence of cryptocurrencies. At the same time, in recent years, interest in cryptocurrencies has continued to grow, and this financial instrument is becoming more and more attractive to individuals. Therefore, an issue of essence of cryptocurrencies is relevant. The main subject of the study is the profitability of cryptocurrencies. The main aim of this work is to identify the determinants of cryptocurrency returns. To achieve this goal, such tasks as the creation of factors reflecting the characteristics of the cryptocurrency market and the use of multifactor Fama-French models for the analysis of cryptocurrency returns were performed. Based on the collected daily data on capitalization, trading volumes and the price of more than 5,000 cryptocurrencies for the period from 01.04.2014 to 21.06.2021, standard factors based on capitalization indicators, trading volumes and the third momentum were built. The main estimation method is econometric modeling using the least squares method. The obtained results of an empirical study indicate a positive relationship between the profitability of groups of cryptocurrencies and the difference in the yields of the upper and lower 30% of cryptocurrencies according to the third moment. The difference in the yields of the lower and upper 30% of cryptocurrencies by market capitalization has a negative impact on the profitability of groups of cryptocurrencies. The main conclusion of the study is that before the beginning of high volatility period, cryptocurrencies could be considered as an asset for the diversification of market risk, but subsequently the cryptocurrency market began to move co-directionally to the stock market. The scientific novelty of the work stems from presenting an assessment of the impact of modeled factors on various groups (portfolios) of cryptocurrencies over certain periods of time. The study recommends to conduct further analysis of the profitability factors of cryptocurrencies on more homogeneous samples.
