The aim of this paper is to find alternative method of executing reimbursement loan, as a form of documentary loan, that is, to investigate new digital technology methods (fintech) to improve the efficiency of the international exchange. Reimbursement loans are often used to credit the trade of overseas goods. The reason of such case is that the shipment of goods by the maritime transport requires a significant amount of time and those trades are often associated with high financial amounts. Since international trade (exchange) is a kind of a generator of society’s progress, it is necessary to explore the possibilities for making international payment cheaper, more efficient and more secure. In this case, we based our research on the implementation of modern technologies, more precisely “blockchain”/DLT (Distributed Ledger Technology) and “smart contracts”. The new reimbursement loan model presented in the paper is based on the aforementioned technologies. It could potentially change not only the documentary lending techniques, but also, eventually, overall financial paradigm. The effectiveness of the application of modern technologies is proven comparing the results of the so called conventional and unconventional reimbursement credit model on a real case involving two companies in Indonesia and Singapore. The paper also tackles on the further implementation of “smart contract” technology and “blockchain”/DLT, thus considering the potential impact of these technologies on overseas trade, credit markets and financial institutions. Finally, the paper argues on the limitations in implementing this new technique (e.g. legal, political and technical challenges).

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.

The major challenges of operating data-intensive of Distributed Ledger Technology (DLT) are (1) to reach consensus on the main chain as a set of validators cast public votes to decide on which blocks to finalize and (2) scalability on how to increase the number of chains which will be running in parallel. In this paper, we introduce a new proximal algorithm that scales DLT in a large-scale Internet of Things (IoT) devices network. We discuss how the algorithm benefits the integrating DLT in IoT by using edge computing technology, taking the scalability and heterogeneous capability of IoT devices into consideration. IoT devices are clustered dynamically into groups based on proximity context information. A cluster head is used to bridge the IoT devices with the DLT network where a smart contract is deployed. In this way, the security of the IoT is improved and the scalability and latency are solved. We elaborate on our mechanism and discuss issues that should be considered and implemented when using the proposed algorithm, we even show how it behaves with varying parameters like latency or when clustering.

The article covers the possibilities of comprehensive use of identification technologies and Distributed Ledger Technology (DLT) for increasing the efficiency of electronic services provided through multi-purpose student cards. The main advantages and disadvantages of the existing intellectual document emission systems in the Belarusian education system are assessed, including: centralized (the “Student Card” project) and decentralized (the electronic student card) ones. The proposal to use the DLT-model for issuing multi-purpose electronic student cards combined with bank payment cards has been grounded. Such model makes it possible to implement new functional capabilities when providing electronic services and has a number of advantages over the existing systems of electronic student documents issuance. The article describes how Public Blockchain and Private Blockchain can be used to issue and control intellectual documents, to accelerate the development of the electronic services provided through Smart Contract, and how the Smart Contract technology can be used to promote fair competition among electronic services providers. The methodology of evaluating the electronic services provider rating basing on the weighting factor of “usefulness” or “being in demand” is proposed. The article provides information on the expected effects of the proposed DLT-model implementation, obtained through the comprehensive use of identification technologies and distributed ledger technology.

Distributed Ledger Technology

In recent years, many industries have adopted technology and digital systems to automate, expedite and secure specific processes. Stakeholders in maritime transport continue to exchange physical documents in order to conduct business. The monitoring of supply chain goods, communication among employees, environmental sustainability and longevity control, along with time framing, all create challenges to many industries. Everyday onboard work, such as cargo operations, navigation and various types of inspections in shipping, still requires paper documents and logs that need to be signed (and stamped). The conversion of traditional paper contracts into smart contracts, which can be digitalized and read through automation, provides a new wave of collaboration between eco systems across the shipping industry. Various data collected and stored on board ships could be used for scientific purposes. Distributed ledger technology (DLT) could be used to collect all those data and improve shipping operations by process expediting. It could eliminate the need to fill in various documents and logs and make operations safer and more environmentally friendly. Information about various important procedures onboard ships could be shared among all interested stakeholders. This paper considers the possible application of distributed ledger technology as an aid for the control of overboard discharge of wastewater from commercial ships. The intended outcome is that it could help protect the environment by sending data to relevant stakeholders in real time, thus providing information regarding the best discharge areas. The use of a structured communal data transference would ensure a consistent and accurate way to transmit data to all interested parties, and would eliminate the need to fill in various paper forms and logs. Wastewater overboard discharges would be properly monitored, recorded and measured, as distributed ledger technology would prevent any possibility of illegal actions and falsification of documents, thus ensuring environmental sustainability.

Abstract: A decentralised, Secure, Peer-to-Peer Multi-Voting System on Ethereum Blockchain is a distributed ledger technology (DLT) that permits virtual votes to be transacted in a peer-to-peer decentralized network. Those transactions are validated and registered through every node of the network, so creating a transparent and immutable series of registered events whose truthfulness is supplied through a consensus protocol. Smart contract automates the execution of agreement that runs routinely as soon as the conditions are satisfied. Smart contract would not need any third parties consequently prevents time loss. By Eliminating the requirement for third parties, consequently, allows numerous processes to be extra efficient and economical. The system is secure, reliable, and anonymous. Smart contract is enforced for the Ethereum network using the Ethereum wallets and also the Solidity language. Users are capable of submit their votes immediately from their Ethereum wallets, and those transaction requests is handled with the consensus of each single Ethereum node. This creates a transparent environment for evoting. A lot of concerning efficiency of the peer-to-peer decentralized electoral system on Ethereum network along with application and the outcomes of implementation are provided in this paper.

Over the last few years, the increasing level of cyber risks derived from the growing connectedness of Industry 4.0 has led to the emergence of blockchain technology as a major innovation in supply chain cybersecurity. The main purpose of this study is to identify and rank the significant barriers affecting the implementation of blockchain technology as a key component of cyber supply chain risk management (CSCRM). This research relied on the “interpretive structural modeling (ISM)” technique in the structure of a hierarchical model to investigate the contextual relationships of identified challenges for blockchain adoption in CSCRM; it also classifies the influential challenges based on their driving and dependence powers. The results highlight that “cryptocurrency volatility” is the challenge at the top level of the hierarchy, implying weak driving power but it is strongly dependent on the other challenges. “Poor regulatory provisions”, “technology immaturity”, “dependent on input information from external oracles”, “scalability and bandwidth issues”, and “smart contract issues” are significant challenges for the adoption of blockchain in cyber supply chain risk management and are located at the bottom level of the hierarchy with higher driving power. The implications for theory and practice of the research are also highlighted.

The application of information technologies leads to the improvement of the companies’ production parameters in each sector according to the criteria for sustainable development. Naturally, in order to achieve efficiency, they must be tailored to the specifics of the industry, in this case the mining industry. The article proposes a methodology for the introduction of Distributed Ledger Technology (DLT) for the transport information flow at a mining company. Based on the chosen organizational structure, the participating actors and the data they share, the information channels are determined. According to the necessary rights of the participants to modify the transactions and the number of channels of the transport information flow, a consensus mechanism Practical Byzantine Fault Tolerant and the so-called smart contract have been chosen. Different DLT platforms are analyzed. Hyperledger Fabric was selected as an appropriate platform in order to ensure the continuity of the system, the asynchronous control of the various channels and the ability to include different actors.

Scope Of Application

Within the framework of this article, the authors carry out the study of the design of the smart contract in the context of jurisprudence and technical sciences. The paper analyzes the legal nature of the smart contract and the issues concerning the scope of application (in relation to distributed ledger technology).The authors conclude that the category of “smart contract” can be defined in technical and legal aspects. In foreign literature, there are two categories: a legal smart contract and a smart contract code (or smart contract). The smart contract as a technical phenomenon represents a computer code that allows automated fulfillment of obligations. From legal point of view, the approaches to the definition of the smart contract depend primarily on the fact that the authors rely on the possibility of using smart contracts only within the framework of distributed ledger technology or other information technologies. At the same time, the majority of authors share the view that the smart contract exists exclusively in relation to the technology of distributed ledgers, namely, the blockchain. The article proposes to define the smart contract as a standard (special) contractual design — a contract concluded by electronic or other technical means, under the terms of which performance of the obligation is carried out without directed explicit additional expression of will (under Part 2 of Article 309 of the Civil Code of the Russian Federation).The article states that the smart contract cannot be qualified as an independent way of ensuring the performance of obligations. Such qualification is possible only if the functional approach to understanding security is applied. The paper examines the main fields of application of smart contracts and possible risks of their application (in terms of statement of terms of agreements in relation to a programming language; in respect of necessity of compliance with such fundamental principles of civil law as legality, fairness, protection of the weak; the need for communication with public authorities and notaries, as well as risks of using smart contracts in relations involving the participation of consumers). A separate set of questions concerns the protection of the rights infringed due to the use of smart contracts.
