the paper examines the phenomenon of decentralized finance (DeFi) as one of the most promising and at the same time controversial areas of the digital economy. DeFi is defined as an ecosystem of protocols and applications based on blockchain and smart contracts that allows financial transactions to be carried out without the intermediation of traditional institutions. It is noted that the key advantages of the technology are transparency, automation, reduction of transaction costs, and expansion of the accessibility of financial services. Simultaneously, risks associated with the lack of unified regulatory approaches, high vulnerability of smart contracts, the use of DeFi for unlawful purposes, and the uncertainty of legal liability are emphasized. Particular attention is paid to AML/KYC problems, as well as the use of DeFi platforms for money laundering of criminal proceeds.
This technical dossier presents the comprehensive software architecture for implementing Ternary Moral Logic (TML) as a deterministic enforcement layer on EVM-compatible blockchain platforms. Unlike traditional "Code is Law" models, TML introduces a "Logic is Constitution" paradigm, where ethical axioms (Prohibit -1, Pause 0, Permit +1) are embedded directly into the execution bytecode. This dataset contains three technical specifications: 01_TML_System_Architecture_and_Ecosystem.pdf: Defines the high-level ecosystem, including the "Lantern Signal" (proof of hesitation), the "Hybrid Shield" (cross-chain redundancy), and the "Goukassian Promise." 02_TML_Technical_Specification_and_FSM.pdf: Details the rigorous Finite State Machine (FSM) logic, Solidity interfaces (ITMLEnforcer), and the "Sacred Zero" epistemic hold mechanism. 03_TML_Security_Audit_and_Adversarial_Analysis.pdf: Provides a deep adversarial analysis and mathematical verification of the "No God Mode" principle, proving that no administrative key can override a constitutional integrity freeze. Status: Released for educational review and technical standardization.
Objective : to critically analyze the possibility of extending the existing spatial criminal law principles to acts committed in the decentralized virtual worlds of the metaverse, and to develop proposals that include updating the approach to establishing jurisdiction over such virtual crimes. Methods : the methodological basis of the research is a set of general scientific methods and approaches of scientific cognition – dialectical, formal logical (analysis and synthesis, induction and deduction), systematic, as well as private scientific methods – formal legal, legal modeling, interpretation. The study relies on an analysis of judicial practice, foreign legislation, technical features of blockchain technologies and decentralized autonomous organizations, which makes it possible to identify gaps in legal regulation and propose conceptually new solutions for determining the crime scene in a virtual environment. Results : the study revealed a limited implementation of the current generally accepted principles of determining jurisdiction in relation to virtual crimes that do not have physical coordinates. The proposed multifactorial jurisdiction model redefines the “crime scene” taking into account factors such as the offender’s digital identity, the nature and location of digital assets, platform management protocols, and the actual damage caused. Assumingly, the immutable and verifiable nature of blockchain transactions can serve as a legal equivalent of a physical presence to establish personal jurisdiction, allowing criminal prosecution to be initiated even in cases where the actual location of the offender remains unknown. Scientific novelty : the paper presents an approach that implies the fundamental transformation of reactive, adaptive legal regulation principles into a proactive, comprehensive framework designed specifically for the unique challenges of the metaverse. A paradigm-changing hypothesis was put forward: that a permanent (stable) digital footprint of the offender in virtual spaces can serve to exercise jurisdiction. The model systematically presents the idea of harm as the most important link between virtual offenses and their consequences in the real world. Practical significance : it is currently impossible to apply legal norms and rules to relations in the metaverse, taking into account their specifics. The main provisions and conclusions of the study can be used to improve the mechanisms of legal regulation of the metaverse and to form international protocols on data exchange and mutual legal assistance for searching and collecting evidence based on blockchain technology. They may help to develop legislative initiatives aimed at creating integrated legal mechanisms that are scalable and resistant to rapid technological changes, characteristic for the digital environment.

The management of resource sharing agreements is being transformed by the introduction of smart contracts, which, alongside decentralized technologies, provide smoother automation, transparency, and trust amongst different parties. This research examines the role that smart contract management systems play in the design, implementation, and control of resource-sharing agreements in the fields of energy, telecommunications, transportation, and digital services. Conventional contract-based practices are plagued by inefficiencies, potential errors, and delays, which smart contracts aim to address by encoding agreement terms into self-executing code stored within blockchain systems. The study examines key architectural building blocks, consensus models, and security elements, focusing on the real-time execution of automated validation, updates, dispute resolution, and contract performance. Practical applications are presented through case studies on decentralized energy markets, bandwidth leasing, and co-utilization of assets. Other concerns are the lack of interconnected systems, enforcement, and private legal structures. The research develops a smart contract lifecycle management model that regulates contracting processes to help organizations develop adequate, compliant, and collaborative resource distribution solutions designed to be scalable. The economic model of spending changes due to the ability of smart contracts, utilizing Blockchain, to share resources, thereby reducing administrative expenses and establishing more resilient mechanisms of dependence in the future.

Based on distributed ledger technology, a new type of arbitration courts has been emerging in the world for the last five years. Their task is to resolve disputes using blockchain and smart contracts. Did the creators of the idea of “distributed justice” really invent a new way to effectively and fairly resolve disputes in the 21st century? Blockchain arbitration involves resolving disputes using the theory of multi-person games, the concept of Schelling point, the idea of decentralized autonomous organizations (DAO), tokens and crowdsourcing. The article attempts to answer the question of whether arbitration decisions made on the basis of economic incentives can be considered to meet the criteria of Aristotelian rectificatory justice. The article is analytical in nature, addressing a topic that has only become relevant in the world a few years ago. The analysis uses theses from cryptoeconomics and game theory. The work initially outlines the problems. Due to the small number of experiences of digital arbitration in the world, the theses and hypotheses of the text, written from the perspective of theory and philosophy of law, require further in-depth analyses.

The management of judicial workflow through traditional paper-based and centralized systems presents a wide range of challenges. This is particularly evident in processes such as: case filing, evidence submission, and verdict execution, where inefficiencies, bureaucratic delays, and security vulnerabilities often undermine the credibility of the judiciary. While electronic systems like Case Management Systems (CMS) and Electronic Court Filing (ECF) have been introduced to digitize court operations, they remain largely centralized and therefore susceptible to unauthorized access, data manipulation, and cyberattacks. Numerous scholars have proposed digital and automated solutions for judicial processes; however, existing models often fail to adequately address key challenges of transparency, immutability, and interoperability across jurisdictions. The main objective of this paper is to provide a blockchain-enabled smart contract framework for judicial workflow management that integrates automation, security, and transparency into legal processes. Data flow and use case diagrams were developed to illustrate the core functionalities of the framework, including case registration, evidence management, judicial rulings, and court scheduling. Access to records within the framework is governed by blockchain’s decentralized consensus mechanism, while smart contracts automate routine judicial tasks based on predefined rules. The adoption of this approach is expected to significantly reduce administrative inefficiencies, minimize fraudulent practices, and enhance trust in judicial outcomes.
The arrival of contracts which are smart has brought a pattern shift in the way agreements are carried off in terms of their performance as well as their implementation. Basically, the smart contracts run on a block chain type of codes, which means that they can also be called as a self-executing contracts because they emerge up with promising features of being efficient, transparent, and most importantly they reduce the dependency on intermediaries. However, in India there are certain growing issues in terms of the adoption of such smart contracts leading to legal and regulatory questions arising. Now, obviously when smart contracts come up with such efficient automated code driven contracts so talking about the traditional agreements which are long governed by well-established legal framework, definitely may face certain challenges in terms of their interpretation, enforceability and also the comparison with the contracts which are smart. This article focuses and explores the legal validity of smart contracts in India, also diving deep and examining their true potential to break the common practices of traditional agreements and try to fill up the regulatory gaps that exist. Now, by analyzing the current legal scenario and expected future challenges, it aims to provide awareness into whether smart contracts are truly a revolutionary tool or a ticking time bomb for the traditional agreements.
In the context of economic globalization and rapid internet development, emerging digital technologies such as cloud computing, big data, and AI are revolutionizing industry production and sales. Smart Contracts, particularly empowered by blockchain advancements, present promising prospects. However, traditional contracts remain dominant in economic activities, especially in China’s vast SME market, where risks of real world transaction instability hinder smart contract adoption. Technical vulnerabilities and ecological security issues in smart contract platforms pose challenges in translating legal language into code. Despite progress in natural language processing, translating legal documents accurately remains difficult, burdening judges and programmers with time costs. Therefore, research on smart contract architecture and legal applications, along with practical solutions, is imperative for both theoretical and practical advancements.
Smart contracts are digital protocols programmed on the blockchain network that automatically execute agreements once pre-defined conditions are met, without human intervention.These contracts are characterized by transparency, speed, and security, as they are stored and documented on a network that cannot be easily modified.Smart contracts rely on software code that defines conditions and procedures, making their implementation precise but also irreversible or easily modified after publication. They are used in several fields, including decentralized finance (DFI), supply chain management, and digital healthcare.Despite these advantages, smart contracts face fundamental challenges, most notably software vulnerabilities that can be exploited by attackers due to the lack of a clear legal framework in many countries, the difficulty of interpreting human intentions through software code alone, and the limited ability of smart contracts to handle exceptional or complex situations.The research topic will be divided into a research plan consisting of an introduction, a section, and two sections.The first section addresses the concept of smart contracts, while the second section explains the legal status of smart contracts in civil law.
Decentralized finance (DeFi) represents a novel financial ecosystem built on open blockchain networks and smart contracts, enabling the provision of financial services without traditional intermediaries. This article examines the conceptual foundations of DeFi, its legal nature, associated risks, and regulatory challenges through a comparative analysis of international practice and the emerging legal framework of Uzbekistan. Particular attention is paid to the composability of DeFi protocols, the legal uncertainty surrounding smart contracts, and the difficulty of identifying responsible parties in decentralized systems. The study analyzes scholarly perspectives, including those of Schär and Zetzsche, and reviews regulatory responses in the United States and the European Union, with a focus on enforcement actions and AML/CFT concerns. It further evaluates risks such as cyberattacks, fraud, money laundering, and consumer harm, highlighting the systemic vulnerabilities of DeFi infrastructures. The article argues that while DeFi offers transparency and innovation, effective regulation requires balancing technological neutrality with robust consumer protection and compliance mechanisms. The findings suggest that Uzbekistan may adopt a cautious, technology-integrated regulatory approach to harness DeFi’s potential while mitigating legal and financial risks.

This paper examines how traditional property law concepts are being reconceptualized to address the challenges of digital assets and environments. As property rights shift from tangible objects to code-based digital assets, fundamental tensions emerge between established legal frameworks and technological realities. Digital assets challenge core property assumptions of rivalry, excludability, and persistence, requiring courts and legislators to adapt centuries-old principles to novel contexts. The analysis explores how diverse legal systems respond to specific digital property types, including intellectual property in non-rivalrous environments, data ownership disputes, cryptocurrency classification, non-fungible tokens, and virtual real estate. Through examination of landmark judicial decisions, emerging legislation, platform governance mechanisms, and technical standards, the paper identifies promising pathways for reconciling traditional property functions with digital innovation. Drawing on comparative approaches from multiple jurisdictions, the research proposes a balanced framework that acknowledges the cultural significance of property institutions while adapting their implementation for digital contexts. The recommendations emphasize flexible, context-sensitive approaches that can maintain essential property functions such as resource allocation, coordination, security, and exchange facilitation, while accommodating the unique characteristics of digital environments.
Background. The rapid advancement of digital technologies has introduced blockchain as a potential tool in public procurement contracts within the public sector. Smart contracts, particularly within civil law frameworks, have gained legislative recognition in jurisdictions such as France and several U.S. states. This development raises important questions about integrating blockchain-based smart contracts into governmental procurement systems, with a view to enhancing procedural transparency and operational efficiency, while acknowledging the limitations and dependencies on institutional frameworks. The central issue lies in clarifying the legal and technical implications of blockchain-based smart procurement contracts. The research examines their potential to streamline public procurement management and improve procedural efficiency, while recognising the need for legal safeguards that maintain administrative law principles and accommodate institutional constraints. Methods. This study adopts a comparative analytical approach, examining relevant legal provisions, technical requirements, and administrative practices across multiple jurisdictions. Various blockchain models—public, private, hybrid, and consortium—are evaluated for their suitability in procurement processes. Legislative experiences regulating smart contracts are analysed to extract best practices and inform a cautious framework for public sector adoption. Results and Conclusions. The analysis indicates that blockchain-based smart procurement contracts may reduce bureaucratic delays and minimise human errors, while providing immutable records that can support accountability. However, successful implementation requires legal and institutional adjustments to address enforceability, liability allocation, interoperability, and data protection. A practical model illustrating each operational step—from drafting to automated execution—is proposed, emphasising feasibility and legal compliance rather than assuming transformative effects. The study highlights the necessity of tailored legislation, standardised protocols, and targeted training for public officials to support the cautious integration of blockchain in public procurement contracting. These measures aim to guide the legally informed and context-sensitive adoption of smart contracts, contributing to sustainable digital transformation in public sector governance.
A TANULMÁNY CÉLJAA tanulmány célja a Bitcoin buborékok kialakulásának vizsgálata, megértése. A buborékok erős hasonlóságot mutatnak a Gartner-féle hype-görbe alakjával, ezért az egyes buborékok és a hype-görbe kapcsolata is ismertetésre kerül. Ezek mellett a Bitcoin-buborékok kialakulását elősegítő tényezők feltárására törekedtünk. ALKALMAZOTT MÓDSZERTAN A Bitcoin árfolyamának historikus adatait elemeztük, melyek alapján a buborékok kirajzolódnak. A buborékok létezésének alátámasztására, illetve a Gartner-féle hype-görbével való azonosítás érdekében kiszámoltuk az egyes buborékok különböző időszakaihoz tartozó kockázatokat, hozamokat is. Illesztettük a hype-görbét a Bitcoin árfolyamának alakulására, illetve a korrelációs kapcsolatot is vizsgáltuk. LEGFONTOSABB EREDMÉNYEK A szórásból számított kockázatok, illetve a relatív szórások is alátámasztották a feltételezést, mely szerint az egyes Bitcoin-buborékok követik a Gartner-féle hype-görbe alakját. A görbék illesztése és a korreláció vizsgálata pedig kimutatta, hogy van kapcsolat a hype és az árfolyam alakulása között. A szabályozás szerepe kritikus lehet a kriptovaluták árfolyamának alakulásában, és a különböző országokban bevezetett szabályozó intézkedések jelentős hatást gyakorolhatnak a befektetői bizalomra és az árfolyamokra. A Bitcoin-bányászat felezése szintén fontos esemény, amely befolyásolhatja a kínálatot és keresletet és ennek megfelelően az árfolyamokat is. Az utánzó magatartás, vagyis a befektetők tendenciája arra, hogy mások viselkedését másolják, szintén jelentős tényező a buborékok kialakulásában. Végül az intézményi szereplők stabilizáló hatását ismertettük. GYAKORLATI JAVASLATOK A tanulmányból kiderül, hogy a fent említett tényezők igen nagy befolyást gyakorolnak a Bitcoin árfolyamának alakulására, melyek közül a bányászatért járó jutalmak felezése a leginkább szembetűnő, illetve számítással alátámasztható. Az új szabályozások megjelenésével nem tudunk számolni, viszont a felezéssel járó árfolyamváltozással igen, melynek fő indikátora az utánzó magatartás, hiszen a befektetők hozamaik maximalizálására törekednek. Ezek alapján a tanulmány rávilágít, hogy egy igen kockázatos befektetési formáról van szó, melynek előrejelzése igen nehéz feladat.
Блокчейн технологиясының дамуымен, алмастырылмайтын токендар (NFT- Non-fungible token) цифрлық меншік тұжырымдамасын қайта анықтады және құқықтық реттеулер тұрғысынан маңызды сұрақтарды көтерді. NFT-лер өнер туындылары, музыка, ойын ішіндегі активтер және виртуалды жылжымайтын мүлік сияқты көптеген сандық активтерді сатып алуда-сатуда қолданылады және орталықтандырылмаған құрылымына байланысты олар дәстүрлі заң негіздеріне толығымен сәйкес келмейді. Бұл жағдай меншік құқығы, зияткерлік меншік, келісім-шарт құқығы және алаяқтық сияқты әртүрлі мәселелер бойынша құқықтық белгісіздік тудырады. Көптеген елдердегідей, Қазақстанда да NFT үшін арнайы құқықтық база жоқ. Бұл жағдай сатып алушылар үшін де, сатушылар үшін де заңды белгісіздіктер тудырады және зияткерлік меншік құқығы, алаяқтық, келісім-шарт құқығы және тұтынушылардың құқықтары тұрғысынан әртүрлі тәуекелдерді тудырады. NFT нарықтарының жылдам өсуі үкіметтердің осы жаңа цифрлық актив сыныбын реттеу қажеттілігін арттырды. Дегенмен, елдер арасында айтарлықтай нормативтік айырмашылықтар бар. Кейбір юрисдикциялар NFT-лерді сандық активтер немесе бағалы қағаздар ретінде жіктеп, оларды қолданыстағы қаржылық ережелерге бағындырса, кейбір елдер арнайы заңдарды әзірлеуде. Зияткерлік меншік құқықтарына келетін болсақ, NFT-лер жай сандық куәлік пе немесе авторлық құқықты беруді де қамтуы мүмкін бе деген жалпы көзқарас әлі жаһандық деңгейде әзірленбеген. Әртүрлі елдерде салық салуға қатысты әртүрлі тәжірибелер де бар. Кейбір елдерде NFT операцияларына қосылған құн салығы (ҚҚС) салынса, басқа елерде олар құн өсіміне салынатын салық ретінде қарастырылады. Алайда, NFT-дің трансшекаралық сипаты мен орталықтандырылмаған құрылымы салық салу процестеріндегі сәйкестік пен аудит мәселелерін туындатады. Бұл мақалада NFT-лердің құқықтық мәртебесі мен салық салу процестері халықаралық тұрғыдан қарастырылады және қолданыстағы ережелер салыстырмалы тұрғыдан бағаланады. Нәтижесінде, NFT экожүйесінің тұрақты өсуі үшін үйлесімді және ашық заңнамалық базаны құру қажет екендігі атап өтілді.

This article addresses the complex issues of choosing legal principles in international commercial contracts in the context of globalization and the rapid development of digital commerce. It analyzes the fundamental principle of party autonomy, in particular its explicit (expressly stated in the contract) and implied (determined based on the circumstances) forms. The paper considers the adaptation of traditional legal approaches to modern challenges such as smart contracts, decentralized autonomous organizations (DAOs) and jurisdictional uncertainty. The immutability of smart contracts, while providing commercial certainty, simultaneously gives rise to legal paradoxes and regulatory gaps, as demonstrated in the case of Van Loon v. US Treasury. The need to obtain legal entity status for DAOs creates a market of “legal shells” offered by various jurisdictions (e.g., Wyoming, Switzerland). The emergence of innovative mechanisms such as multi-signature arbitration in dispute resolution leads to the privatization of enforcement proceedings. The aim of the study is to examine the adaptation of traditional legal approaches to modern challenges such as smart contracts, decentralized autonomous organizations, and jurisdictional uncertainty. The paper uses legal analysis and case study methods. The results show that the immutability of smart contracts creates legal paradoxes, while mandatory public law rules limit the voluntary autonomy of the parties.
This article offers a comprehensive analysis of the current state of legal regulation of blockchain technology and smart contracts in Ukraine and examines their underlying legal nature. Written against the backdrop of global innovations and practical applications of distributed-ledger technology, the study addresses the urgent need to harmonise Ukraine’s regulatory framework with that of the European Union. Adopting an interdisciplinary perspective, the author integrates legal, economic, and technological considerations, viewing blockchain not merely as an innovative IT infrastructure but also as a socio- legal phenomenon capable of transforming tax, registration, and corporate processes. The introduction substantiates the relevance of the research: the rapid expansion of the digital economy, the widespread adoption of virtual assets, and the imperative to reduce corruption risks in the public sector all necessitate legislative adaptation and the introduction of new legal concepts. The purpose of the article is to develop a national regulatory model that reconciles technological innovation with the principles of transparency, legal certainty, and protection of market participants’ rights. The core of the study focuses on five potential areas for deploying blockchain in public administration: electronic tax reporting, accounting for electronic invoices, automated tax payments via smart contracts, an open register of taxpayers, and real-time monitoring of goods flows. The author demonstrates that implementing these solutions can reduce operational costs for businesses, significantly decrease errors and fraud, and enhance public trust in state institutions. Special attention is given to the legal status of NFTs and other tokenised assets. Based on an analysis of Ukrainian and international legislation, the article argues that the transfer of economic copyrights via NFTs requires a written (including electronic) agreement bearing a qualified electronic signature, clearly defined licensing terms, and integration with official state registers to verify legal title.

Abstract This study outlines the creation, implementation, and assessment of a Blockchain–AI integrated chain-of-custody (CoC) framework for managing digital forensic evidence. The research sought to improve the integrity of evidence, transparency, and automation, tackling the shortcomings of conventional manual CoC processes. The suggested system was executed utilizing Hyperledger Fabric (6 nodes, PBFT consensus) and Ethereum testnet (10 nodes, PoA consensus), attaining an average block time of 1.2–3.8 seconds and transaction latency of 85–150 milliseconds. Smart contracts, RegisterEvidence(), VerifyCustody(), AccessGrant(), and LogActivity() streamlined the custody procedure, achieving a 99.6% integrity validation rate in blockchain-only mode and a complete 100% validation when paired with AI anomaly detection. The AI subsystem utilized a CNN–LSTM combined model that was trained on 500 labeled transaction logs, achieving 97.2% accuracy, 0.96 precision, 0.97 recall, and an F1-score of 0.965. Correlation analysis indicated a robust positive association (r = 0.94) between AI anomaly detection and blockchain integrity verification. Scalability evaluations over 100–5,000 transactions demonstrated throughput between 135 and 80 transactions per second (TPS), while memory usage rose from 32% to 77%, verifying effective resource utilization. The system exhibited strong alignment with SDG 16 (Peace, Justice, and Strong Institutions) and SDG 9 (Industry, Innovation, and Infrastructure), achieving scores of 0.98 for transparency, 0.95 for accountability, 0.96 for innovation, and 0.94 for digital infrastructure. Comparative benchmarks indicated significant enhancements compared to baseline CoC systems: +13.1% in integrity validation, + 60.7% decrease in latency, + 97.2% increase in accuracy, and + 50% improvement in scalability. These empirical findings confirm that the Blockchain–AI framework provides a secure, transparent, and smart forensic environment, capable of revolutionizing judicial evidence handling and enhancing institutional trust via automated, data-driven processes.
As healthcare ecosystems shift toward digital-first operations, personal health data faces unprecedented security and privacy risks from increasingly sophisticated cyber threats. This paper examines how the integration of Artificial Intelligence (AI), including Agentic AI, blockchain, and cloud computing, can establish an advanced security framework for resilient healthcare data management. Unlike traditional siloed systems, the proposed model leverages AI-driven anomaly detection, multi-agent orchestration, and explainable AI (XAI) for real-time threat prediction and adaptive defense. Blockchain contributes decentralized trust, tamper-proof auditability, and consent-enforcing smart contracts, while cloud platforms deliver elastic scalability, encrypted storage, and hybrid multi-cloud deployment models. The framework also incorporates federated learning, Model-Chaining Protocols (MCPs), and Zero-Knowledge Proofs (ZKPs) to enhance interoperability, preserve privacy, and enable verifiable compliance. Findings highlight significant improvements in confidentiality, integrity, and availability (CIA) of healthcare data, while simultaneously addressing regulatory obligations such as HIPAA and GDPR through embedded governance and risk orchestration layers. Despite challenges around system complexity and policy harmonization, the paper provides a state-of-the-art synthesis and proposes actionable best practices for healthcare practitioners and policymakers, including adopting continuous AI-powered risk monitoring, blockchain-based patient-centric data ownership, and automated compliance verification mechanisms. Overall, the convergence of AI, blockchain, and cloud technologies—augmented by governance-driven orchestration—offers a future-proof, cyber-resilient architecture for safeguarding personal health data in digital-first healthcare ecosystems.
سازمانهای خودگردان غیرمتمرکز (DAO)، به دلیل ویژگیهایی چون فقدان مدیریت انسانی متمرکز و ساختار فراملی، با مفهوم سنتی شخصیت حقوقی در تضاد ماهوی قرار دارند. پژوهش حاضر از توصیف این بنبست شناختهشده عبور کرده و به یک پرسش راهبردی پاسخ میدهد: نظام حقوقی ایران چگونه میتواند با الهام از مبانی فقهی و تحلیل تطبیقی تجارب نوین جهانی (مانند وایومینگ)، مدلی جدید تحت عنوان «شخصیت حقوقی الگوریتمی» را طراحی و شناسایی کند؟ این تحقیق با روش توصیفی-تحلیلی، پس از اثبات ناکارآمدی چارچوبهای فعلی برای حل بحران مسئولیت و صلاحیت قضایی، به عنوان یافته اصلی، ارکان و الزامات یک مدل مفهومی نوین را ارائه میدهد. این مدل، اهلیت و موجودیت نهاد را نه بر ارکان انسانی، بلکه بر شفافیت کد، قابلیت حسابرسی الگوریتم و معرفی یک عامل ثبتشده استوار میسازد. مقاله همچنین با بررسی تطبیقی رویکردهای جهانی و پاسخگویی به انتقادات کلیدی، اعتبار و کارآمدی مدل پیشنهادی را تقویت مینماید. نتیجهگیری پژوهش آن است که مواجهه کارآمد با DAO مستلزم عبور از راهکارهای اصلاحی و حرکت به سمت قانونگذاری جدید و ویژهای است که این شخصیت حقوقی فناورانه را به رسمیت بشناسد و ضمن فراهم آوردن بستر نوآوری اقتصادی، پاسخگویی حقوقی و قضایی این نهادها را در برابر حاکمیت تضمین نماید.
