Since 2016, China has officially regarded blockchain technology as a subversive innovation that will fundamentally transform major industries. Current blockchain projects in China are dominated by private or consortium blockchains that have their accessibility firmly controlled; for public blockchains such as Bitcoin and Ethereum, access is free for all. Not surprisingly, by weakening state control of digital data, public blockchains may neutralise China’s decades of efforts in building internet filtering systems. The existing development trajectory of private and consortium blockchains is likely to advance steadfastly, and citizens and companies in China may be required to use state-controlled blockchains.

Blockchains have caught the attention of governments, businesses, and researchers due to their potential to revolutionize the way data is stored and consumed. Despite the current interest in blockchains globally, there has been unsatisfactory progress of this promising technology in developing countries, including Tanzania. One factor hindering the advancement of blockchain in the country is the lack of knowledge of the technology itself. Challenged by the situation, this study implemented a blockchain lab to provide a platform for users to explore and practice various concepts of blockchain. This online lab, called Dinari, was implemented using Ethereum blockchain and was hosted on a cloud server. Experiments were conducted to verify the performance of the developed lab. Results from the experiment show that the platform gives an average transaction processing time of 15.17 seconds. The processing times were within an acceptable range of performance when compared with other online platforms, such as Mainnet and Kovan that provide average processing times of between 8.8 seconds and 18.3 seconds. The study can be scaled up in future to deploy more use cases, including health, in addition to the existing payment use case.

Texto completoResumen
Zusammenfassung Im rechtswissenschaftlichen wie regulatorischen Diskurs um Blockchain-Plattformen werden bislang die wertbildenden Faktoren für Kryptowährungen vernachlässigt. Hier sollen – insbesondere am Beispiel von Ethereum – die Gebühren für Blockchain-Transaktionen untersucht werden. Ihre Bedeutung ist kaum hoch genug einzuschätzen, denn sie determinieren die Attraktivität von Blockchain-Ökosystemen, können zu Lock-In-Effekten für Anlagen führen und sind Treiber von (Umgehungs-)Innovation. Transaktionsgebühren sind in den Protokollen von Blockchain-Systemen niedergelegt, für die auf das klassische IT-rechtliche Axiom von Lessig zurückgegriffen wird – Code is Law. Eine genaue Analyse des Zustandekommens von Blockchain-Protokollen zeigt allerdings, dass die technologieenthusiastischen Narrative der Blockchain strikt an der Grenze ihrer Programmierung enden. Der Code von Blockchains ist nicht „unveränderlich“ oder „rein technisch“, er ist hochpolitisch und häufig von monetären Interessen geprägt. Protokolländerungen entstehen durch Updates in informellen Strukturen, in denen Charisma sowie ökonomischer Druck maßgeblich sind und die durchaus zentralistische Züge tragen. Daher sind Belange des Schwächeren- und Minderheitenschutzes auf den Plan gerufen; das Problem der Transaktionsgebühren soll in diesem Beitrag mit den Lösungen des Kapitalmarktrechts sowie auch des AGB- und Gesellschaftsrechts abgeglichen werden. Am Ende steht der Appell für eine tatsachengebundene Einordnung von Blockchain-Systemen als menschlich determinierte, verantwortlich geführte Systeme. Zudem empfiehlt sich eine regulatorische Reflexion der Funktionsbedingungen von Blockchains als Infrastruktur.

Abstract: In our thorough exploration of the intricate relationship between blockchain technology and the legal landscape, we uncover three key intersections: legality, law-like characteristics, and legal applications. Delving into the realm of legality, we analyze the profound impact of jurisdiction-specific regulations governing cryptocurrencies, intellectual property, and taxation. This includes considerations such as identity verification, exchange regulation, securities laws, bankruptcy regulations, and anti-money laundering enforcement, shaping the multifaceted legal terrain. Shifting focus to the law-like characteristics inherent in permissionless blockchains, our examination reveals decentralized governance facilitated through consensus mechanisms. The blockchain protocol operates as a dynamic "constitution," actively shaping the behavior and incentives of network participants, with forking introducing a distinctive form of institutional innovation during disagreements over protocol changes. Expanding our exploration to the transformative legal applications of blockchain, we emphasize smart contracts and decentralized autonomous organizations. Despite remarkable advancements, challenges persist in automating intricate contractual arrangements and organizational functions, particularly within the context of multi-stage interactions embedded in broader legal and social frameworks. In conclusion, our comprehensive findings highlight that blockchain's unique capacity for direct economic value exchange requires innovative legal treatment. It not only influences user incentives through its rule-based structure but also catalyzes transformative changes across legal and contractual domains. However, as the blockchain landscape evolves, persistent limitations become apparent, particularly in addressing relational agreements and ensuring constitutional resilience. The evolving nature of this technology continues to shape and redefine the intersection between blockchain and the law

Blockchain is a technology that is quite popular and has been adopted in various fields in recent years. This technology has caught the attention of researchers in the health sector because of its innovation which is considered capable of providing the necessary guarantees for the safe processing, sharing, and management of sensitive patient data. There are many problems with falsifying reports and withholding important information from patients, which is considered medical fraud. Hyperledger, a type of private Blockchain, is very suitable for healthcare applications. A private blockchain is a restricted type of blockchain network created by an entity. This type of network is limited to those with access permissions. In addition, private blockchains usually use a centralized verification system and are controlled by the network's creators. Hyperledger Fabric is one example of a permissioned blockchain that can play a role in implementing patient-centric, interoperable healthcare systems

Decentralized finance (DeFi) refers to a set of newly emerging financial products and services that operate on decentralized platforms using blockchains to record and share data. DeFi products and services are conducted without a trusted central intermediary such as a bank, and they include payments, lending and borrowing, trading and investments, capital raising (crowdfunding), and insurance. An important innovation that allowed for the development of DeFi was the growth of programming capability on blockchains. This innovation allows for the creation of computer code called smart contracts that can be invoked by users without going through a centralized intermediary. DeFi may pose financial stability risks, that are exacerbated by the fact that both are currently largely outside the prudential regulatory perimeter, which we discuss.

Blockchain is a novel distributed ledger technology. Through its features and smart contract capabilities, a wide range of application areas opened up for blockchain-based innovation [5]. In order to analyse how concrete blockchain systems as well as blockchain applications are used, data must be extracted from these systems. Due to various complexities inherent in blockchain, the question how to interpret such data is non-trivial. Such interpretation should often be shared among parties, e.g., if they collaborate via a blockchain. To this end, we devised an approach codify the interpretation of blockchain data, to extract data from blockchains accordingly, and to output it in suitable formats [1, 2]. This work will be the main topic of the keynote. In addition, application developers and users of blockchain applications may want to estimate the cost of using or operating a blockchain application. In the keynote, I will also discuss our cost estimation method [3, 4]. This method was designed for the Ethereum blockchain platform, where cost also relates to transaction complexity, and therefore also to system throughput.

With the rapid development and technological innovation in the energy market, peer-to-peer (P2P) energy trading, as a decentralised and efficient trading model, has been widely studied and practically applied. However, in P2P energy transactions involving multiple prosumers, there are challenges such as information asymmetry, trust issues, and transaction transparency. To address these challenges, blockchain technology, as a distributed ledger technology, provides solutions. In this paper, we propose a blockchain technology-based prosumer–virtual power plant (VPP) two-tier interactive energy management framework to assist P2P energy transactions between multiple prosumers. In this framework, the virtual power plant acts as a leader and sets differentiated tariffs for different prosumers to equal the distribution of social welfare. The various prosumers act as followers and respond to the leader’s decisions in a cooperative manner. Blockchain’s immutability and transparency enable prosumers to participate in P2P energy trading with greater trust, share idle energy, and share revenues based on contribution. In addition, given the uncertainty of renewable energy, this paper employs a stochastic planning approach with conditional value at risk (CVaR) to describe the expected loss of VPP. Ultimately, as verified by the arithmetic simulation, the blockchain co-governance transaction model effectively supports energy coordination and optimization of complementarities while ensuring the utility of each transaction node. This model promotes the application of renewable energy in local consumption, while facilitating the innovation and sustainable development of the energy market.

ABSTRACT In this research, we often refer to Nakamoto's (2008) seminal paper, “Bitcoin: A Peer-to-Peer Electronic Cash System,” to consider his proposed abstracted characteristics and how auditors could look at companies' transactions interfacing to a private/semi-private blockchain with Nakamoto's general characteristics and address the related audit domain for such transactions. We then take these design requirements for auditors and, using design science research (DSR), we consider the transaction processing and contracting contexts that match those requirements in permissioned blockchains.The blockchains discussed in this paper would typically be business-to-business or business-to-consumer, private or semi-private, and residing in either a private, semi-private, or public cloud. Those blockchains will each have their own design and operational procedures, including validation procedures (the miners). We consider the audit issues of data reliability, data security, and transaction transparency in accounting transactions that lend themselves to a permissioned blockchain as well as other contextual issues.

Abstract: Voting systems have evolved over time, with paper voting becoming the most common worldwide. The introduction of electronic voting in the last decade has brought long-term solutions, but problems remain, especially in terms of security, trust, transparency and operation. Estonia has emerged as a leader in electronic voting despite limited blockchain integration. Blockchain technology offers a promising solution to these challenges through immutability and decentralization. However, current blockchain-based voting technology often lacks good solutions or lacks adequate measurement and evaluation. This article presents a new blockchain-based electronic voting platform designed to solve these problems in many elections. Our platform, which uses blockchain technology, prevents external intervention when starting the election by completing the administrative process in the central distribution system. Always be transparent while protecting voters' identities with homomorphic encryption. Our extensive testing and comparisons on our independent blockchain projects show that there is little difference between public and private blockchains. The main innovation of our solution is the provided management system using blockchain and homomorphic encryption, transparent process and stable security and self-assessment. This research contributes to the development of electronic elections to increase the security, transparency and efficiency of the democratic process.

The implementation of blockchain technology in supply chain finance (BcSCF) offers a conducive way for entrepreneurial financing. Extending the resource-based view (RBV), a traditional perspective approach is espoused to trigger scholarly discussions, pining the development of research fronts on Blockchain-as-a-Service (BaaS) in addressing small and medium-sized enterprises (SME) financing constraints. This paper suggests that, despite the operational challenges of blockchains and the necessity to focus on core business activities, BaaS is promising, with significant efforts in terms of cost-savings, efficiency, and reliability with reduced risks. This study provides insight on BaaS contributions to fostering entrepreneurial finance as well as contributing to the literature on the accomplishments of BaaS within BcSCF provisions for particularly Ghanaian SMEs. Therefore, detailed studies into the viability of technologically-enabled types of SME finance are essential, necessitating more research. Resultantly, some forward-thinking research issues for researchers in the disciplines of innovation, technology, entrepreneurship, finance, and decision science have been presented.

The article proposes UML diagrams of the property right distribution module using NFT fractalization based on blockchain technology, which allow to develop software for the implementation of the modern way of fractions generation according to the ERC-1155 standard. A blockchain is a distributed database that is shared among the nodes of a computer network. As a database, a blockchain stores information electronically in digital format. Blockchains are best known for their crucial role in cryptocurrency systems, such as Bitcoin, for maintaining a secure and decentralized record of transactions. The innovation with a blockchain is that it guarantees the fidelity and security of a record of data and generates trust without the need for a trusted third party. This standard was chosen for the impossibility of offering fractions for sale on other platforms, ensuring the uniqueness of the proposed decentralized application. The main reason for the development is to create a module located on the network blockchain, ensuring the security of functionality with cryptographic algorithms from one of the most secure blockchain — Ethereum. The task of development is to implement functionality that ensures the fulfillment of all functional requirements, the most important of which are the creation of a unique NFT to the user’s property, its Fractionalization and the sale of fractions to other users.

Compared to other applications of distributed ledger technologies, for example, in decentralized finance, non-fungible tokens, and logistics, Blockchain applications in the energy industry have not found widespread dissemination and fell short of market expectations during the Blockchain hype in the late 2010s. In semi-structured qualitative interviews with leading providers in the energy industry, conducted from 2019 to 2021, hurdles in energy applications are compared with a control group of additional interviews with representatives of companies operating in IT and FinTech. The analysis uses a framework covering technical feasibility, desirability, and economic viability, as well as the role of regulatory frameworks. The interviews reveal that the first Blockchain applications suffered from a combination of technological constraints and inter-platform competition. Due to the permissionless configuration of the early energy Blockchains, they were slow in terms of transaction speed compared to existing platforms and prices per transaction were high, in addition to high degrees of complexity related to requirements from both critical-infrastructure systems and financial market regulation. The analysis further points to the slow adoption of Blockchain applications in the energy sector being related to business models rather focusing on products and platforms as well as on transactional rather than procedural use cases, with a high degree of standardization of the offering and low levels of inclusiveness concerning processes. The move from transaction platforms to innovation platforms and the emergence of Blockchain as a service provider—plus technical advances with regards to high-frequency transactions combined with the increasing importance of use cases, such as proof of origin for fuels or e-charging—may induce a shift from pilot applications to commercialization within the larger innovation ecosystem. While the involvement of Blockchain solutions in energy markets increases with pilot projects and with this, the acceptance of players and stakeholders in the energy ecosystem, a big hurdle for innovation remains the regulation of energy markets to allow for peer-to-peer trading, a usage-driven distribution of network costs, and bottom-up pricing markets.

In this paper, we demonstrate the multiple points of innovation when combining blockchain technology with Internet of Things (IoT) and security frameworks. The deployment and use of IoT device networks in smart city environments has produced an enormous amount of data. The fact that those data are possessed by multiple sources that use independent systems for data collection, storage, and use impedes the exploitation of their value. Blockchains, as distributed ledgers, can be used for addressing the development of a universal system for data collection and distribution. Smart contracts can be used to automate all the processes of such a network, while at the same time, blockchain and the InterPlanetary File System (IPFS) protect sensitive data through anonymity and distributed storage. An innovative and open IoT blockchain market of applications, data, and services is proposed that: (i) provides the framework upon which objects and people can exchange value in form of virtual currencies, for assets (data and services) received; (ii) defines the motivation incentives according to social and business context for humans and smart objects to interact. The specific marketplace is piloted through a cross-border trial between Santander and Fujisawa, in the context of the M-Sec project, validating thus the interoperability, efficiency, and data protection principles.

The study addressed the problem of developing a mechanism for introducing blockchain technology into the system of accounting and analytical support for public sector entities. In the course of the research, the volumes and types of financial violations by public sector entities were analyzed. Identified violations were committed by public sector entities, and their significant share fell on the system of accounting and analytical support, in particular, financial reporting, budget execution. Legal restrictions on the introduction of blockchain technology for public sector entities were outlined. The absence of a number of acts in the field of digitization, protection of state secrets, cyber security, international standards, etc. in the legal field was established. The characteristics and mechanisms of blockchain technology were described, the types of blockchains based on permission models (open, closed) were defined. The technological characteristics of the use of blockchain platforms in the system of accounting and analytical support of public sector entities have been determined. The need to use blockchain applications such as smart contracts was indicated. It is noted that the use of smart contracts can be developed on blockchain platforms such as Ethereum, NXT, and Hyperledger; their key characteristics were described. A comparative description of transactions of state funds in the traditional accounting system and with the use of blockchain systems is given. The problem of the materiality of the transaction cost when transferring large volumes of data was outlined using the Ethereum platform as an example; its shortcomings were identified. The development of a mechanism for introducing blockchain technology into the system of accounting and analytical support using the Hyperledger platform, which has an open-source community focused on the development of a set of stable frameworks, tools, and libraries for deploying enterprise-level blockchains, was described. The advantages and disadvantages of introducing blockchain technology into the system of accounting and analytical support have been determined.

Proof-of-Work (PoW) based blockchains typically allocate only a tiny fraction (e.g., less than 1% for Ethereum) of the average interarrival time (I) between blocks for validating smart contracts present in transactions. In such systems, block validation and PoW mining are typically performed sequentially, the former by CPUs and the latter by ASICs. A trivial increase in validation time (τ) introduces the popularly known Verifier's Dilemma, and as we demonstrate, causes more forking and hurts fairness. Large τ also reduces the tolerance for safety against a Byzantine adversary. Solutions that offload validation to a set of non-chain nodes (a.k.a. off-chain approaches) suffer from trust and performance issues that are non-trivial to resolve. In this paper, we present Tuxedo, the first on-chain protocol to theoretically scale τ/I ≈1 in PoW blockchains. The key innovation in Tuxedo is to perform CPU-based block processing in parallel to ASIC mining. We achieve this by allowing miners to delay validation of transactions in a block by up to ζ blocks, where ζ is a system parameter. We perform security analysis of Tuxedo considering all possible adversarial strategies in a synchronous network with maximum end-to-end delay Δ and demonstrate that Tuxedo achieves security equivalent to known results for longest chain PoW Nakamoto consensus. Our prototype implementation of Tuxedo atop Ethereum demonstrates that it can scale τ without suffering the harmful effects of naive scaling up of τ/I in existing blockchains

Purpose The purpose of this paper is to argue for the role of the blockchain, i.e., distributed ledger technology, in building innovative business models, including machine money, autonomous economic agents and decentralised organisations. Design/methodology/approach The paper is conceptual/argumentative. As such, it draws on research on (e-)commerce, theories of markets, disruptive innovation and extant studies and conceptual work at the intersection of cryptocurrencies, machine-to-machine commerce and the Internet of Things. Findings The authors highlight three application areas for blockchains, whereby they can function as applications, can help develop autonomous economic agents and can lead the development of decentralised autonomous organisations. With regards to the question of market disintermediation, the authors suggest that, rather than complete disintermediation, the most probable scenario is that of new types of intermediaries finding previously unthinkable roles to play in mediating blockchain-based economic transactions. With regards to the inhibitors that slow down the technology’s adoption and, therefore, the development of new business applications, the authors posit that these relate mainly to the inherent risk of the technology, infrastructure requirements, scepticism of early decision makers and the lack of required new skills and competencies. Originality/value The authors examine how new forms of digital money and technologies embedding trust in decentralised networks will alter markets and commerce, at a time when many regulatory issues remain unresolved; in doing so, the authors focus on how blockchain-enabled technologies can be used to enable and further develop decentralised trusted peer-to-peer transaction ledger systems and applications and lead to sustainable business models.

Rachid Guerraoui was the rst keynote speaker, and he got things o to a great start by discussing the broad relevance of the research done in our community relative to both industry and academia. He rst argued that, in some sense, the fact that distributed computing is so pervasive nowadays could end up sti ing progress in our community by inducing people to work on marginal problems, and becoming isolated. His rst suggestion was to try to understand and incorporate new ideas coming from applied elds into our research, and argued that this has been historically very successful. He illustrated this point via the distributed payment problem, which appears in the context of blockchains, in particular Bitcoin, but then turned out to be very theoretically interesting; furthermore, the theoretical understanding of the problem inspired new practical protocols. He then went further to discuss new directions in distributed computing, such as the COVID tracing problem, and new challenges in Byzantine-resilient distributed machine learning. Another source of innovation Rachid suggested was hardware innovations, which he illustrated with work studying the impact of RDMA-based primitives on fundamental problems in distributed computing. The talk concluded with a very lively discussion.

Blockchain technology has the potential to drive innovations across various industries, businesses, and use cases. It is broadly recognized that innovation is a vital source of competitive advantage in a rapidly changing environment. High expectations surround blockchain’s potential for contributing to sustainable economic and social development. However, current blockchain projects still show high failure rates. The associated side effects of such failure rates generate a negative impact on economic and social sustainability performances such as corporate governance, risk management, finance management, human resources and culture management, and competitiveness. This paper assesses adoption models and their risk and success factors. Building on a novel, integrated adoption model to operationalize, measure and manage blockchain-driven business innovation in a sustainable way, we assessed its applicability with an empirical study across 20 industry sectors and 125 business leaders. The results reveal that the developed adoption model holds the potential to support the sustainable usage of blockchain technology for business innovations, not limited to a specific industry or use case. Further case studies and industry activities can be carried out to continue its validation in future works.

Blockchain technology is one among the recent innovations in the computing industry. Blockchains have gathered a widespread interest in the industry mainly due to their security promise. Despite the anticipated benefits of Blockchains, there are several limitations which make the technology less suitable in large scale applications such as banking, one being low throughput. Several initiatives to improve the throughput of Blockchains are being tried out both in the academia and the business worlds but no systematic classification of the initiatives and the strategies used has been done. This study explores Blockchain performance improvement initiatives and classify the initiatives by the improvement strategy used. This study has found that, out of 365 articles on the area of Blockchain performance, 300 were solution proposals aimed at improving the performance of Blockchains. The most used strategies in these proposals were alternative to PoW, sharding and multi-chain architecture.

Nowadays, open innovations such as intelligent automation and digitalization are being adopted by every industry with the help of powerful technology such as Artificial Intelligence (AI). This evolution drives systematic running processes, involves less overhead of managerial activities and increased production rate. However, it also gave birth to different kinds of attacks and security issues at the data storage level and process level. The real-life implementation of such AI-enabled intelligent systems is currently plagued by the lack of security and trust levels in system predictions. Blockchain is a prevailing technology that can help to alleviate the security risks of AI applications. These two technologies are complementing each other as Blockchain can mitigate vulnerabilities in AI, and AI can improve the performance of Blockchain. Many studies are currently being conducted on the applicability of Blockchains for securing intelligent applications in various crucial domains such as healthcare, finance, energy, government, and defense. However, this domain lacks a systematic study that can offer an overarching view of research activities currently going on in applying Blockchains for securing AI-based systems and improving their robustness. This paper presents a bibliometric and literature analysis of how Blockchain provides a security blanket to AI-based systems. Two well-known research databases (Scopus and Web of Science) have been examined for this analytical study and review. The research uncovered that idea proposals in conferences and some articles published in journals make a major contribution. However, there is still a lot of research work to be done to implement real and stable Blockchain-based AI systems.

PurposeDespite blockchain's potential supply chain benefits, few organizations have moved beyond pilot projects. The paper aims to explore blockchain adoption intentions for supply chain applications using two theoretical perspectives: innovation diffusion theory (IDT) and institutional theory (IT).Design/methodology/approachBased on theory, five propositions were developed addressing the intention to adopt blockchain. The propositions were tested using scenario-based experiments with supply chain professionals. To provide additional insights, interviews with 21 supply chain professionals in 15 organizations representing 8 industries were content analyzed.FindingsExperiments suggest that the intention to adopt blockchain is higher when there are government regulations regarding product origin, organizations are using updated cloud-based information systems and organizations are working with third-party consultants. The content analysis suggests that organizations that face normative pressures to adopt blockchain supply chain applications and recognize blockchain's relative advantage, compatibility and complexity are more likely to be actively seeking information about and adopting blockchain supply chain applications. The authors synthesize findings and provide new propositions to guide future research.Originality/valueUsing a multi-method approach, the study provides an important window into supply chain managers' perceptions of the necessary conditions to support organization-level blockchain adoption. The findings also indicate key characteristics present in supply chain networks poised for blockchain adoption.

Blockchain technology is one among the latest innovations in computing industry. Blockchains have gathered widespread interest in the industry due to their potential as secure data storage. Despite the potential benefits of blockchains, there are several limitations which hinders mass deployment, one of these limitations being low throughput. Low throughput has limited blockchain adoption in large scale applications such as banking or mobile payments. This study addresses this limitation through development of a performance enhancement algorithm called Path of Trust (PoT). PoT uses off-chain stratergy in which transactions meeting certain criteria bypass the main chain and sent direct to the recipient. The PoT algorithm was incorporated into a blockchain wallet that was developed as a mobile app. Experiments were run to verify the performance of the developed solution. Based on the experiments performed, the performance of the blockchain based on the developed solution was improved when compared to the original blockchain. With PoT algorithm running, the average transaction processing time was 12.81 secs per transaction compared to 18.52 secs when PoT was not running.

Blockchain technology, originally developed for digital currencies, has evolved to offer transformative prospects for enhancing financial security and efficiency beyond its initial application. This review paper explores the expansive utility of blockchain technology across various domains, with a special focus on its implications for green logistics innovations within the oil industry, drawing a comparative analysis between Nigeria and the USA. Through a comprehensive review of existing literature, this study aims to uncover the multifaceted impact of blockchain on streamlining operations, ensuring transparency, and fostering sustainability in the oil sector's supply chain management.
The methodology hinges on synthesizing findings from peer-reviewed articles, industry reports, and case studies to construct a holistic view of blockchain's role in mitigating traditional challenges faced by the oil industry, such as fraud, inefficiencies, and environmental concerns. By comparing the progress and setbacks in Nigeria and the USA, the paper delineates the influence of regulatory frameworks, technological infrastructure, and stakeholder engagement on the adoption and effectiveness of blockchain solutions.
Key findings reveal that blockchain technology can significantly elevate financial security and operational efficiency, offering a robust framework for transparent, immutable transactions and supply chain oversight. However, the comparative analysis highlights a notable divergence in adoption levels and outcomes, attributed to varying degrees of technological readiness, regulatory environments, and commitment to sustainability goals between the two countries.
Conclusively, the paper emphasizes that the broader application of blockchain in enhancing green logistics and sustainability within the oil industry requires a concerted effort among policymakers, industry leaders, and technology providers. It advocates for targeted investments in technology infrastructure, clearer regulatory guidelines, and stronger collaborations to harness blockchain's full potential, suggesting a pathway towards more secure, efficient, and sustainable industry practices.

Traditional corporate governance patterns are based on the interaction among composite stakeholders and the various forms of separation between ownership and control. Stakeholders cooperate around the Coasian firm represented by a nexus of increasingly complex contracts. These well-known occurrences have been deeply investigated by growing literature and nurtured by composite empirical evidence. Apparently, unrelated network theory is concerned with the study of graphs as a representation of (a)symmetric relations between discrete objects (nodes connected by links). Network theory is highly interdisciplinary, and its versatile nature is fully consistent with the complex interactions of (networked) stakeholders, even in terms of game-theoretic patterns. The connection between traditional corporate governance issues and network theory properties is, however, still under-investigated. Hence the importance of an innovative reinterpretation that brings to “network governance”. Innovation may, for instance, concern the principal-agent networked relationships and their conflicts of interest or the risk contagion and value drivers – three core governance issues. Networks and their applications (like blockchains, P2P platforms, game-theoretic interactions or digital supply chains) foster unmediated decentralization. In decentralized digital platforms stakeholders inclusively interact, promoting cooperation and sustainability. To the extent that network properties can be mathematically measured, governance issues may be quantified and traced with recursive patterns of expected occurrences.
