There has been a rise in the demand for blockchain-based smart contract development platforms and language implementations. On the other hand, smart contracts and blockchain applications are generated using non-standard software life cycles, which means that, for example, distributed applications are rarely updated, or bugs are fully addressed by releasing a newer version, leading to security flaws and challenges for users to adopt the technology. Smart contracts have gained significant attention due to their potential to automate and secure various transactions in diverse domains. However, the increasing adoption of smart contracts has also raised concerns about security vulnerabilities and potential risks. In this paper, an overview of smart contracts was discussed in detail. It further distinguished and compared smart contracts security with conventional security regarding security, privacy, communication channel, etc. Different platforms for smart contracts, such as Bitcoin, Ethereum, Counterparty, Stellar, Monax, and Lisk, are also discussed in this paper. Some proposed techniques are used in different areas for handling security threats in smart contracts. In addition, a taxonomy of the smart contracts security application was proposed, which attempts to solve some of the flaws and inadequacies in smart contracts. The study also provides a comprehensive smart contracts security scenario with different techniques. Lastly, the possible attacks posed by threats and vulnerabilities of the smart contracts are provided. The security threats and vulnerabilities addressed in this study are unique to smart contracts.

A smart legal contract is a binding contract in which some or all the contractual terms are defined in and/or performed automatically by a computer program. It runs on a blockchain platform and carries the features of the blockchain of being automatically self-executed, and immutable, providing permanent records with real-time information, and reducing cumbersome documentation using high processing power. In major jurisdictions around the world, it is generally recognised that the smart legal contract is capable of having contractual force just like a traditional natural language contract. It has the potential to have entire complex commercial contracts written in and executed by computer codes. This chapter explains the concept and operation of the smart legal contract. Its advancement as an integral part of legal practices and a mainstream area of law is described in chronological order. The judgement of the first significant case relating to the use of smart contracts is unpacked. Whilst the acceptance of smart contracts by legal practices has gained pace, novel legal issues have been emerging in this area of law. This chapter identifies and proposes solutions to key legal issues arising from the operation of computer code and the resolution of disputes of smart legal contracts.
Blockchain technology has transcended its origins in cryptocurrency and is now poised to transform various aspects of the legal and business landscape by implementing smart contracts. Smart contracts, which operate on blockchain networks and are self-executing, programmable contracts, have the potential to completely change how agreements are made, carried out, and enforced. In order to shed light on their benefits, drawbacks, and potential future ramifications, this article examines the development of blockchain-based intelligent contracts and their influence on legal and corporate procedures. Traditional methods of managing and carrying out contracts are frequently time consuming, expensive, and prone to disagreements. Blockchain technology's smart contracts provide a decentralized, automated, and impenetrable means of drafting, carrying out, and upholding contracts. This article explains how smart contracts can streamline processes across multiple industries, including finance, real estate, supply chain management, and intellectual property by carefully exploring the technological foundations and real-world use cases of smart contracts.

 The 21st century is known for its strong technological advancements, where blockchain technology and a cutting-edge product built on it like cryptocurrencies are evolving daily. According to recent research, bitcoin is particularly appealing to both experienced and novice investors. Numerous individuals and legal entities around the world accept cryptocurrencies as payment. Cryptocurrency can be used to purchase both products and services. As a result, the need for legal regulation of cryptocurrency is high on the priority list.
 The purpose of this article is to evaluate the legal status of cryptocurrencies, namely what its legal character is and whether it is conceivable to treat cryptographic currency as an object of private law, as property, as electronic money, or as virtual cash. Is it better than traditional currencies, and if so, what are they? All of the foregoing will be reviewed in light of the suggestions of the United States of America, Australia, Argentina, Brazil, Germany, Zealand, Japan, South Korea, China, Georgia, and the European Central Bank.
Introduction. This scientific article dedicated to certain aspects of such virtual benefits/assets as the NFT token (non-fungible token) and place of them in the obligations relationship. The legal framework and legal practice regarding non- non-fungible token is currently absent, which is a characteristic situation not only for domestic jurisprudence, but also for the world. In view of the above, there is a need to investigate the nature of this phenomenon. Summary. The article analyzes the proposed legislative definition of "virtual asset" in relation to the NFT token. The study of individual features of this phenomenon makes it necessary to turn to its displayed technical characteristics at the current stage. Yes, it is determined that the NFT token performs an authentication function and cannot exist independently without its attachment to another object of civil rights. Without such a combination, exclusively as a code (a set of signs), the token cannot be regarded as an intangible (virtual) benefits, since the token certifies a subjective right to another object of civil rights, and therefore should be considered precisely as an asset (benefits), which has a providing nature. Attention is focused on the fact that one of the main problems of legal uncertainty in this category is the question of what exactly individuals acquire when buying an NFT token, since in fact the token is usually associated with another object, which gives it a real value. The relationship between the non-fungible token and the start-contract was analyzed and the possible legal consequences of their interaction determined. Conclusions. Non-fungible tokens exist in a decentralized system and are closely related to the smart contract already at the stage of their creation, therefore, provided there are no imperative requirements from the law, the latter can be considered as a type of civil law contract, which, in turn, due to constant interaction the connection between them makes it possible to single out certain features of the binding nature of this phenomenon.

The subject . The paper considers the legal status of non-fungible tokens – a technology that allows to secure and confirm the possession of a certificate that refers to a specific digital object, based on a distributed ledger (blockchain). The purpose of the article is to research the current state of the legal status of NFTs in the Russian Federation, as well as to determine the applicability of the current Russian legislation to NFTs. The research methodology is based on the application of methods of systemic and structural analysis, formal logic, as well as methods of legal forecasting and interpretation of legal norms. The results. There is a lack of comprehensive studies on this issue in legal science. The value of NFT is substantiated through the categories of "rivalrousness" and "scarcity". The process of creating NFT - "mint", that is, the tokenization of a digital object, is described. The legal status of NFT is investigated, as a result of which it is concluded that the token is not equivalent to a digital object, but rather acts as a custodian of information about this object. Taking into account, firstly, the independent nature of the NFT, which is not only a digital copy of the original work, secondly, the vast scope of utilitarian application and, thirdly, its independent commercial value, it is indicated that in the perspective of the development of legislation and judicial practice, NFT should be regarded as an independent digital asset, the rights to which are subject to legal protection. Conclusions. At present, Russian legislation does not contain a legal structure suitable for NFTs. The problems of using NFT are highlighted, including the "tokenization" of other people's works, interference in the operation of trading platforms using technical vulnerabilities, as well as fraud. Since NFT can confirm not only the right of ownership, but also represent any subjective right, it is assumed that this technology can be used to maintain decentralized blockchain registries of real estate, shares, members of the society, vote in elections, as well as to verify identity, while simultaneously ensuring the protection of personal data.
