A smart contract is a technology that allows the creation of a negotiation process capable of running independently, without human intervention. This chapter intends to frame the figure of the “smart contract” from a legal point of view. It shows that the smart contract is an advanced tool in the context of a contractual relationship. The possibility of making a smart contract “the contract” in a legal meaning opens up scenarios which have hitherto been unexplored for contract law. It is still difficult to determine to what extent current rules are adequate to govern this phenomenon. The chapter will therefore conclude with a review of the strengths and weaknesses of the smart contract technology and with some suggestions for a future smart contract law.

While blockchain applications are at a nascent stage of development in developing countries (referred to as “Southern countries” in this article), they are already having significant economic, political, and social impacts.1 Writing and implementing contracts are one area that is likely to benefit from blockchain. Specifically, smart contracts, which execute automatically when certain conditions are met, can address some of the deficiencies of existing problems associated with contract laws and their enforcement in Southern countries. In many cases, the real challenge is in the interpretation of the contract rather than the breach by a party. Often, an uncertainty about the meaning of the terms in a contract presents questions of interpretation.2 Since smart contracts are enforced by software codes, many of the interpretation-related problems are not likely to occur in such platforms. Among the major benefits, smart contracts can dramatically reduce costs associated with verification and enforcement. Other advantages include higher speed, precision, efficiency, and transparency. A key challenge in this is how Southern countries can benefit from blockchain and its potentially disruptive application in smart contracts. In this article, we attempt to assess the potential of blockchain-powered smart contracts in Southern economies vis-a`-vis traditional contracting mechanisms.
Blockchain ist mittlerweile schon quer durch die Gesellschaft fast jedem ein Begriff. Die Blockchain-Technologie, sprich was die Blockchain genau ist, wie sie aufgebaut ist und verwendet werden kann, ist hingegen für viele noch ein Mysterium. Smart Contracts sind Computerprogramme, die auf der Blockchain-Technologie basieren und diese Computerprogramme werden mit Programmiersprachen entwickelt. Stellt man sich die Frage, welche Programmiersprache man am Besten verwendet, so merkt man relativ schnell, dass die Auswahl an verfügbaren Programmiersprachen für Smart Contracts enorm groß ist und kontinuierlich größer wird.Diese Arbeit versucht die Frage zu klären, welche spezifischen Eigenschaften eine Sprache für die Entwicklung von Smart Contracts besitzen muss. Zuerst werden allgemeine Anforderungen an eine Sprache für die Entwicklung von Smart Contracts evaluiert. Im zweiten Schritt werden die identifizierten Anforderungen mit Spracheigenschaften in Beziehung gesetzt, damit geprüft werden kann, ob und inwieweit eine gewählte Programmiersprache für die Entwicklung von Smart Contracts geeignet ist.Mit den Erkenntnissen dieser Arbeit wird am Beispiel der Programmiersprache Solidity, welche als die de facto Standardsprache für Smart Contracts gilt, analysiert, wie geeignet die Sprache für die Entwicklung von Smart Contracts tatsächlich ist.
A contract generally only binds its parties. Security agreements, which create a security interest in specific personal property, stand out as a glaring exception to this rule. Under certain conditions, security interests not only bind the creditor and debtor, but also third-party creditors seeking to lend against the same collateral. To receive this extraordinary benefit, creditors must put the world on notice, usually by filing a financing statement with the state in which the debtor is located. Unfortunately, the Uniform Commercial Code (U.C.C.) Article 9 filing system fails to provide actual notice to interested parties and introduces risk of heavy financial losses. To solve this problem, this Article introduces a smart-contract-based U.C.C.-1 form built using Lexon, an innovative new programming language that enables the development of smart contracts in English. The proposed “Lexon U.C.C. Financing Statement” does much more than merely replicate the financing statement in digital form; it also performs several U.C.C. rules so that, for the first time, the filing system works as intended. In demonstrating that such a system remains compatible with existing law, the Lexon U.C.C. Financing Statement also reveals important lessons about the interaction of technology and commercial law. This Article brings cryptolaw to the U.C.C. in three parts. Part I examines the failure of the U.C.C. Article 9 filing system to achieve actual notice and argues that blockchain technology and smart contracts can help the system function as intended. Part II introduces the Lexon U.C.C. Financing Statement, demonstrating how the computer code implements U.C.C. provisions. Part II also examines the goals that influenced the design of the Lexon U.C.C. Financing Statement, discusses the new programming language used to build it, and argues that the prototype could be used now, under existing law. Part III proposes five innovations for the Article 9 filing system enabled by the Lexon U.C.C. Financing Statement. Part III then considers the broader implications of the project for commercial law, legal research around smart contracts, and the interplay between technology-neutral law and a lawyer’s increasingly important duty of technological competence. Ultimately, by providing the computer code needed to build the Lexon U.C.C. Financing Statement, this Article demonstrates not only that crypto-legal structures are possible, but that they can simplify the law and make it more accessible.

The International Swaps and Derivatives Association (ISDA) Master Agreement (MA) is the prevailing contract in the Over-the-Counter (OTC) derivatives market. Its efficacy derives from, inter alia, the network effect. As the OTC derivatives market expanded so did users of the MA. During and after the MA’s creation, the market underwent extensive deregulation and the standard-form agreement soon filled the lacuna left by retreating regulation. Its ubiquity in the market has created a level of trust and confidence, not only in the terms of the MA itself but between parties which may not have otherwise entered into a business relationship. With the impending introduction by ISDA of a smart contract version, this article investigates whether automation will harmonize or disrupt trust and confidence in the MA.

With the development of technology innovations it becomes possible to regulate relations between the parties through smart-contracts. Smart contracts are based on blockchain technology, which is a decentralized distributed ledger system consisting of a chain of computers connected to one server. This technology is so convenient for parties to the treaty, because it gives the participants of smart contract an opportunity to exchange property values without intermediaries such as notaries, guarantors, etc. It is to be noted that smart contracts are not resolved in most countries. Now in many countries, however, there is a formation of the legislative framework in the sphere of the smart contracts by considering a smart contract like an element of a legal transaction with the introduction of blockchain technology, which is explained by the desire to keep up with technical progress. There were some attempts in the International Private Law to conclude smart-contracts. As is well known the traditional question in the International Private Law is a conflict of law that is so popular now for smart contracts that using blockchain technology involve multiple jurisdictions. That’s why the choice-of-law issues in the regulation of relevant relations, including the projection concerning choice of law in those States where super-priority is adjusted for those innovations, requires further research. In this article the authors have analyzed the concept and essence of smart contracts (Smart Contracts), researched the problem of conflict of law, applicable to such contracts. In particular analysis focused specifically on the Rome I Regulation in the aspects of smart contract management. The paper also touches upon problematic aspects related to choice of law applicable to the smart contracts in Ukraine. In conclusion, the prospects for the use of smart contracts in International Private Law.
Smart contracts and their promise of automatic performance capture legal and entrepreneurial imaginations. But the excitement around the technology led to some confusing legal responses. Several legal scholars use chronology to help reduce the confusion and place smart contracts within what is already familiar about computational contracting. According to this line of thinking, blockchain-based smart contracts simply represent the next technological advancement in a long history of computable contracting technologies. However, other scholarly work suggests that such a chronological explanation under-simplifies the nature of the linkages between smart contracts and other forms of code-connected contracts. This Article offers a unified theory of code-connected contracts as a tool for guiding risk allocation and design trade-off discussions when considering whether to use one or more forms of code-connected contracts. Specifically, this Article argues that the many variations of code-connected contracts should be viewed along an axis of state transition complexity. Doing so brings to the forefront the fact that the issues facing smart contracts used to merely automate performance of contractual obligations differ in terms of both magnitude and novelty from algorithmic decision-making tools used by parties to fill gaps in contractual terms and other computational contracting tools. In other words, the state transition complexity theory of code-connected contracts set out in this Article offers an analytical tool for anticipating legal and business risk when using computational contracts. Ultimately, the state transition complexity theory of code-connected contracts demonstrates that getting to the core legal issues presented by code-connected contracting requires an analysis of the details of each specific implementation. As with most legal questions, proper analysis depends on facts and circumstances. Nevertheless, many of the core legal issues will arise because emerging technology, like all technology, is social technology. Thus, the implications of the state transition complexity theory of code-connected contracts are that many of the legal issues are not terribly new, and we should not forget to look to existing jurisprudence and scholarly work in contract law and corollary disciplines.
Smart contracts are self-executing digital transactions using decentralized cryptographic mechanisms for enforcement. They were theorized more than twenty years ago, but the recent development of Bitcoin and blockchain technologies has rekindled excitement about their potential among technologists and industry. Startup companies and major enterprises alike are now developing smart contract solutions for an array of markets, purporting to offer a digital bypass around traditional contract law. For legal scholars, smart contracts pose a significant question: Do smart contracts offer a superior solution to the problems that contract law addresses? In this article, we aim to understand both the potential and the limitations of smart contracts. We conclude that smart contracts offer novel possibilities, may significantly alter the commercial world, and will demand new legal responses. But smart contracts will not displace contract law. Understanding why not brings into focus the essential role of contract law as a remedial institution. In this way, smart contracts actually illuminate the role of contract law more than they obviate it.
Explores the implications of transactional scripts used in situations where there is less than total trust between the parties. In particular, this Article asks the question of how parties to these next generation transactional scripts can seek redress and remedies in the event that the transactional script does not perform according to the parties' intent. Until parties feel safe that any errors can be corrected, large-scale implementation of transactional scripts will be hobbled. Part II of this Article articulates why the term "transactional scripts" is preferable to "smart contracts" and describes the utility and potential of transactional scripts. Part III identifies several factors that hinder greater expansion of the use of transactional scripts. It goes on to identify uncertainty of enforcement as the most important barrier to transactional script innovation, finding that parties will be reluctant to entrust bigger and more complex transactions to transactional scripts until the parties are comfortable that an external mechanism is capable of correcting errors in the execution of the transaction. This lack of reliable enforcement mechanisms is a problem exacerbated by the characteristic of distributed ledger technology, which is to move only forward, preventing revisions or reversals of preexisting entries. Part IV explores and critiques possible mechanisms that may be able to provide error correction, including statutory law, private law, online dispute resolution, public/private regulatory partnership, and common law. Part V concludes the Article, noting that the expansion of transactional scripts' utility will be tethered to the security provided by available error-correction mechanisms. Only as contracting parties become assured that the integrity of their transactional intent will be effectuated will transactional scripts be adopted for use.

A number of tools used within LegalTech 2.0. and 3.0. apply blockchain and distributed ledger technologies 3 . This is not a new technology, the concept of distributed record keeping is over 50 years old (a memorandum no. RM-340-PR by Paul Baran 4 from 1964). What is innovative, is its application in a law firm and its adaptation to the needs of lawyers. Blockchain has been around for a number of years (paper by a 'Satoshi Nakamoto 5 ' from 2008) and has been identified by, among others, the European Union 1.
This article primarily focuses on how to set up a smart contract with Solidity. Considering that the usage and examples of smart contracts are increasing day by day, the number of contracts written with Solidity is increasing at the same rate. These contracts, in which computers describe the will of the parties in codes, have a relieving effect for the legal sector as well. Although “language” is the basis of the law, smart contracts are perfect for contracts that can be put forward concretely without human emotions. In this article, I started by defining what a smart contract is. Based on the definition of smart contract, I wrote in which sectors and in which projects smart contracts are used. Finally, I introduced the Solidity programming language, which is the main purpose of this article, and I wrote and explained the Inheritance Contract with Solidity.

This work begins with an explanation of fundamental concepts about Bitcoin and Blockchain and then explores the main definitions of smart contracts in the updated literature, demonstrates some categories of smart contracts, explores the most widely used platforms that support smart contracts, and gives greater prominence to the Ethereum platform for its more robust characteristics regarding the creation and storage of this type of contract. It then concludes by demonstrating the advantages of smart contracts in relation to traditional contracts, as well as addressing their legal validity.
This essay examines whether the smart contract innovation is capable of displacing the orthodox adherence to traditional contracts. This examination is underpinned by an analysis of the legality of smart contracts in which it is exemplified that smart contracts ought to be considered legally binding instruments. The essay proceeds to explore the superiority of smart contracting in a technical and theoretical basis. The advantages generated through smart contract automaticity and enforceability present a concrete basis for undermining reliance on traditional contracts. Blockchain Technology also enhances the benefits of smart contract by acting as a smart contract enabler through guaranteed performance and enforceability. Nevertheless, such novel technologies inevitably suffer from several shortcomings. This essay considers examples illustrating the inflexibility of smart contracting. Apart from being susceptible to hacking and code exploitation, smart contracting is unable to deal with ambiguities and potential modifications. Overall, this suggests that the advantages of smart contract practice are currently confined to some specified limited scenarios. Smart contracts perform a different function to traditional contracting by merely guaranteeing technical enforceability as opposed to legal enforceability. This essay thus concludes that, for the time being, it is prone to regard smart contracting as a supplement to traditional contract rather than an outright displacement.
Are the technologies advanced enough to replace lawyers and the judiciary in the negotiation and enforcement process? Is it possible for a program code to be a contract that binds the parties named in it? What is a smart contract and what challenges does it pose to the law? The present study aims to clarify and show the advantages and disadvantages of using smart contracts in civil law.
Smart contracts promise to materialize a lifelong dream as they purport to be self-executing, cost-efficient, free of human error and other inefficiencies commonly attributed to traditional contracts. Nevertheless, the fact that smart contracts originate from and embody human interactions also makes them imperfect and prone to be affected by the shortcomings of the relationships that they regulate. This chapter explores some of the most important questions raised by the idea of smart contracts, including their contours and substance, whether they should be regarded as contracts or not, their relationship with the legal system (both domestic and international) and the comparison between smart contracts and traditional contracts. The rigidity, tamper-proof nature, self-sufficiency and completeness of smart contracts are generally viewed as important features, which make them particularly attractive for international commercial transactions where language, culture, different legal standards and other differences are usually the source of tension besides raising transaction costs. Smart legal contracts, however, are not a complete replacement either for traditional contracts, or for all human involvement in commerce.
The combination of smart contracts with blockchain technology enables the authentication of the contract and limits the risks of non-compliance. In principle, smart contracts can be processed more efficiently compared to traditional paper-based contracts. However, current smart contracts have very limited capabilities with respect to normative representations, making them too distant from actual contracts. In order to reduce this gap, the paper presents an architectural analysis to see the role of computational artifacts in terms of various ex-ante and ex-post enforcement mechanisms. The proposed framework is assessed using scenarios concerning data-sharing operations bound by legal requirements from the General Data Protection Regulation (GDPR) and data-sharing agreements.
