Performance Evaluation of a Blockchain-Based Smart Livestock Farm Management Platform

Modern international hydrocarbons turnover is becoming more autonomous and decentralized. This process is facilitated not only by the introduction into contractual practice of such network technologies as smart contracts and blockchain platforms, but also by the wide dissemination of sources of non-governmental regulation (lex petrolea). In the context of the network paradigm of private international law, the classic problem of conflict of laws is exacerbated. The author considers the conflict-of-laws aspects of the use of smart contracts based on blockchain technology in cross-border oil and gas transactions, taking into account the fact that the use of computer algorithms does not create a new contract, but is only a special form of transaction. Such “automated” transactions in the oil and gas sector involving multiple jurisdictions create uncertainty in their legal regime. In the absence of a comprehensive substantive legal regulation, and in connection with the phenomenon of lex petrolea, the conflict-of-laws method of regulation predominates. The author shares his reasoning concerning the possibility of extending the application of Regulation No. 593/2008 of the European Parliament and the Council of the European Union “On the Law to be Applicable to contractual obligations (Rome I)” to smart contracts. The author concludes that existing regulation is quite applicable to smart contracts in cross-border oil and gas transactions. Another question is whether the law, which is applicable by virtue of a conflict-of-laws rule, provides for an appropriate substantive basis. To date, special legislation on smart contracts has been passed in only several American states. It is predicted that in the future, private international law will not only determine the law applicable to smart contracts, but will also be a guide to disseminating the positive experience of legal regulation of smart contracts in different countries.

The world today has realized the vast technological evolution that has greatly shaped the production and management functions of business enterprises. Traditional contracts can take weeks or even months to initiate, and there have been numerous instances of breaches and lack of trust for contracts in both the private and public sector. A smart contract can be defined as a self-executing contract that utilizes blockchain technology to digitally enforce, verify, or facilitate the performance or negotiation of a contract. Owing to the security and decentralized system exhibited by blockchain technology, smart contracts can foster transaction credibility between contracting parties without the necessity of third parties as exhibited in traditional contracts. Any business organization that aims at achieving greater heights in management and production dimensions must consider utilizing robust technologies that are aimed at bolstering its competitive edge. Owing to the newness of smart contracts, characterized by very few studies on the same, this research reviews how smart contracts through blockchain technology can be implemented in an organization to enhance performance and outlines the applications, benefits, and limitations associated with such contracts.

Blockchain and drone technologies can operate in cooperation with each other. As the number of drones increases, managing them becomes a significant challenge. A swarm of drones, also referred to as swarm drones, must operate reliably and securely. In this study, blockchain technology is utilized through a smart contract to ensure both security and reliability. Swarm drones are deployed for surveillance missions, where each execution corresponds to a single mission. These missions are represented using a simple model. A smart contract maintains the essential mission data in the model. The mission is divided into smaller tasks. Until all the tasks are completed, they are executed by drones in parallel. The smart contract, implemented on the Ethereum platform, securely exchanges information with the drones. The proposed model functions dynamically. It reorganizes when drones leave or new drones join the system. Because blockchain platforms have limited resources, particularly in memory and the number of permissible execution operations, optimizations are applied to both the smart contract and drone programs to accommodate these constraints within the surveillance framework. The proposed surveillance model is implemented and simulated to analyze its dynamic behavior.

In recent years, an individual under the pseudonym of Satoshi Nakamoto devised a revolutionary technology called blockchain as the engine behind the first decentralized virtual currency called Bitcoin. A radical concept departing from government-centric controlled currencies, Bitcoin has emerged as a disruptive technology with the power to revolutionize business and its processes. Advantages of the blockchain include decentralized control, immutability, elimination of central authority and solution of concurrency problems in traditional databases. Leveraging on the advantages of blockchain technology defined above, this paper discusses the potential application of blockchain technology for storage of Islamic marriage certificates. Marriage certificates are documents issued to couples to legally recognize their marriage. Due to its paper-based nature, there is significant risk for them to be forged or frauded. These issues can be addressed effective using blockchain. The proposed application was implemented using smart contracts on a simulated Ethereum platform. A smart contract is designed to execute automatically under certain predefined conditions. The use of smart contracts eliminate manipulation by a single party. In addition, the immutable concept of blockchain ensures that data integrity is always preserved, greatly reducing the risk of fraud.

PurposeCross border trade, involving different business environments between the sellers’ and buyers’ countries, may result in conflicts because of asymmetry in the information structure across the borders. The International Chambers of Commerce (ICC) has laid down ground rules on terms of shipment and payment, enabling harmonization and standardization of business process, and fixing of responsibilities for international trade. The international commercial (INCO) terms by ICC define the duties, obligations and cost borne by the exporter and the importer. An exporter’s uncertainty looms once the goods cross his/her border. Therefore, there is a need for a smart contract that is secured, transparent, legitimate and trustworthy. The authors propose a blockchain technology-based smart global contract (BTGC) framework for international trade.Design/methodology/approachIn this paper, the authors develop the framework based on value chain analysis (VCA) of international trade and an ontology-driven-blockchain-design approach. The paper analyzes the sequence of activities in the value chain of global trade, the terms of the contract, the data structure templates, the validation rules and the points-of-failure, and proposes the smart contract blockchain structure.FindingsThis paper proposes the BTGC framework considering the INCO terms 2020; it provides the validation rules and the probability of failures; and identifies the elements that cause the halting of contracts and conditions of creation of side blockchains. The framework also includes the governance of the BTGC system.Research limitations/implicationsThe proposed framework not only has implications at the firm level as it automates and secures a global sale contract but also is expected to harmonize the global-trade process as well. The developers may use the attributes, data structure templates and the rules identified in this paper for developing the GC software. Future research may consider using case analysis, class diagrams and the related steps for developing the blockchain software.Originality/valueThis paper proposes a complete value chain of global contract (GC) concerning exports, an ontology of GC and a blockchain-based smart-contract framework based on global standards. Besides, it specifies the elements of fraud (such as the non-integration of side chains) and uncertainty, i.e. the probability of failures. Such a framework will harmonize the global-trade process and build an international standards for smart GC based on blockchain technology (ISSGCBT), which is not yet done.

With the wide application of Internet of Things (IoT) technology, large volumes of multimodal data are collected and analyzed for various diagnoses, analyses, and predictions to help in decision-making and management. However, the research on protecting data integrity and privacy is quite limited, while the lack of proper protection for sensitive data may have significant impacts on the benefits and gains of data owners. In this research, we propose a protection solution for data integrity and privacy. Specifically, our system protects data integrity through distributed systems and blockchain technology. Meanwhile, our system guarantees data privacy using differential privacy and Machine Learning (ML) techniques. Our system aims to maintain the usability of the data for further data analytical tasks of data users, while encrypting the data according to the requirements of data owners. We implement our solution with smart contracts, distributed file systems, and ML models. The experimental results show that our proposed solution can effectively encrypt source IoT data according to the requirements of data users while data integrity can be protected under the blockchain.
