Navigating the next wave with innovations in distributed ledger frameworks

Over the last decade, information technology has contributed significantly to the evolution of financial markets, without, however, revolutionising the way in which financial institutions interact with one another. This may be about to change, as some market players are now predicting that new database technologies, such as blockchain and other distributed ledger technologies (DLTs), could be the source of an imminent revolution. This paper analyses the main features of DLTs that could influence their potential adoption by financial institutions and discusses how the use of these technologies could affect the European post-trade market for securities. The original protocol underlying DLTs has its roots in the anarchic world of virtual currencies, which operate outside the conventional financial system. The public debate on DLTs has also been very much focused on the revolutionary potential of the technology. This paper concludes that, irrespective of the technology used and the market players involved, certain processes that feature in the post-trade market for securities will still need to be performed by institutions. DLTs could, however, stimulate a reorganisation of financial markets, which could in turn: (i) reduce reconciliation costs, (ii) streamline the post-trade value chain, and (iii) allow more efficient use to be made of collateral and regulatory capital. It should, nevertheless, be remembered that research into DLTs and their uses is at an early stage. The scope for financial institutions to adopt DLTs and their potential impact on mainstream financial markets are still unclear. This paper discusses three potential models of how market players could adopt DLTs for performing core post-trade functions. The DLT could be adopted either: (i) in clusters, (ii) collectively, or (iii) peer to peer. The evaluation of the three adoption models assumes that they are all equally compatible with the regulatory framework. It shows that, assuming this to be the case, they would each have different advantages and costs.

Chapter 11 - Applications of blockchain technology for improving security in the internet of things (IoT)

There are currently different views in the scientific community on how the distributed ledger technology (DLT) relates to the blockchain technology. Some view them as synonyms, whereas others view DLT as the umbrella term for all blockchain related technologies. This paper approaches this topic by deriving definitions and core characteristics of DLT and blockchain technology. By using these definitions and an additional market research, a categorization for DLT and blockchain can be created. This categorization will operate as an additional component for IT-architects to decide on appropriate DLT solutions for their specific distributed ledger use cases.

A phenomenon-based approach is used to learn more about how blockchain technology could improve Ghana’s economic sectors in terms of cost savings, efficiency, and reliability with reduced risks. With our proposed blockchain-enabled frameworks, we describe how blockchains’ Internet-of-Things (IoTs) and Distributed Ledger Technologies (DLTs) might reduce transaction, contract, and monitoring-related costs in the Agriculture & Agro-processing sector’s supply chains. We also demonstrate how Smart Contracts (SMCs) and Distributed Ledger Technologies (DLTs) can improve time and cost-based efficiencies in local procurements, logistic contract execution, and supply chains across the Mining & Minerals processing sector. With the help of IoTs, DLTs, and SMCs, information asymmetries in the finance sector can be reduced to improve the financing for Small and Medium-sized Enterprises (SMEs). The Technological-Organizational-Environmental (TOE) elements remain crucial in the adoption of blockchain technology. As a result, it’s critical to provide adequate frameworks for blockchain adoption.

Electronic voting system is the process of polling votes and counting votes. In most of the countries voting may now be done electronically, there are still several difficulties involved, including the expense of paper, how ballots are organized, the possibility of varying results when tallying the votes, and others. Duplicate votes pose a significant concern as they can be fraudulently cast by individuals. To focus on this issue, Distributed Ledger Technology (DLT) is employed to enhance the voting procedure in a secured manner. A directed acyclic graph is used by the Internet of Things Application (IOTA), a promising distributed ledger system. Faster transaction confirmation, high scalability and zero transaction fees are achieved via the Directed Acyclic Graph structure. In both IOTA tangle and blockchain technology, the public cast duplicate votes. The unauthorized user can create duplicate votes in the blockchain as well as IOTA tangle. This can be focused in this proposed method. The double spending problem can be solved by using Crow Search Algorithm (CSA). This Optimization problem produces an improved result for resolving double spending in e-voting systems.

Today, blockchain technology is playing a vital role in the professional world as one of the most important discoveries and creative developments. Blockchain technology is continuously advancing and revolutionizing our society. An overview of blockchain technology is presented in this paper. The blockchain is a distributed ledger technology that allows different transactions and operations to be recorded in a chain of blocks without requiring a third party. A growing number of businesses and industrial communities are exploring blockchain technology as a technological option. In the last decade, blockchain technology has completely changed the paradigm of computer applications. Blockchain was created with the vision of creating an immutable, confidential, open-source, decentralized P2P network located on a decentralized network to facilitate data sharing. An overview of blockchain applications in different areas is presented. We provide a timely summary of blockchain research for individuals and organizations interested in this field. This paper presents an overview of blockchain technology, listing all the key characteristics, benefits, and features which make blockchain technology both superior and unique. We also discuss popular consensus protocols and taxonomy for blockchain systems.

Blockchain technology and distributed ledger technology (DLT) offer a secure, distributed, and tamper-proof way to store and exchange information. However, apart from standard cryptocurrency-based networks, innovations and process improvements based on the blockchain technology have mostly remained on the conceptualizing stage and have not yet reached mass adoption. There is a high demand for practical experiences from developing blockchain and DLT based systems in various domains outside FinTech. This work seeks to contribute to this gap by presenting real-world experiences from developing a proof of concept for automatizing conditional payments in social benefits and healthcare domains. We found that the key conditions for making these blockchain-based solutions viable are (1) attaining technological maturity and competences, (2) ecosystem thinking and adequate governance of these ecosystems, and finally (3) achieving legal and regulatory predictability. Furthermore, we discuss technological choice, business, and ethical considerations relevant to practitioners and research communities.

Background: The use of blockchain technology for tracking and tracing (T&T) in supply chains is the subject of lively debate in scientific literature. However, distributed ledger technology (DLT) does not have to have the characteristic blockchain structure and often performs better without such a structure. Generalized DLT for T&T in supply chains has rarely been discussed in the existing literature. Methods: This article presents an exploratory case study research of eight companies to identify the main goals, and problems that the companies have when they engage in T&T. This practical perspective is complemented by a theoretical systems thinking perspective. Based on these two foundations, we discuss the usefulness of blockchain technology and, more generally, DLT for T&T in supply chains. Results: Based on our analysis, DLT is only necessary in special cases, e.g., when the owners of the data have an interest in deleting the data, but the data stakeholders do not. In the other cases examined, DLT competes with other technologies, such as conventional, centralized databases in combination with digital signatures. Furthermore, it became evident that DLT can only be useful for supply chain tracing. The technological features of DLT do not provide any benefit for supply chain tracking, i.e., the timely communication of the status of a physical good. Conclusions: Distributed ledgers often have a disadvantage in that they are very complex and, therefore, expensive. DLT should preferably only be used when it is technologically necessary or the simplest/cheapest choice, which is probably not all that often. Finally, the usefulness of distributed ledger technology and its integrated smart contract technology is highly dependent on how easy it is to link the real physical world to a digital record/contract in an error-free and tamper-proof way. Currently, such a definite link exists only in very few cases and is often impossible.

The Internet of Things (IOT) is integrated with supply chain management process to track the product. To track the product smart tags is used. The smart tags like QR code and NFC is used. But with the technology enhancement the block chain is introduced into the supply chain management process. The block chain is the great revolution that data in the centralized form is transformed in to a decentralized manner. The distributed Ledger Technology (DLT) is one of the method used in ethereum block chain. The main advantage of using DLT is, it offers decentralized, privacy-preserving and verifiable process in the smart tags. In existing system only single server was used to maintain all the process like supplier, manufacturer and distributor. In this application we are using different server which was more secure than existing system. The proposed solution in this paper is it checks the product evidence during the entire lifecycle of the product by using the smart contract. The data can be immutable by using smart contract with ethereum block chain. The duplication is manipulated by the block chainserver.

Distributed Ledger Technologies (DLTs) and blockchain systems are used in various higher-level departments, government sectors and commercial industries. This article reviews how DLTs and blockchain systems work with IOT devices and how it provides security and scalability. The metaverse sets a new standard for social media sites and 3D virtual spaces. Moreover, the key aim of the virtual world is to safeguard the metadata of IOT customers. Additionally, crypto is an effective solution due to its openness, data integrity, and accountability characteristics. So, we review the two new burning technologies of crypto and the virtual world from a methodological perspective, i.e. data collection, saving data, allocation, integration, and data confidentiality are all aspects of data management. By each strategy, in this article, we discuss the methodological techniques of the meta chain and then investigate the potential benefits of blockchain technology. Further, we analyze how blockchain will influence other critical enabling technologies in the metaverse's service world, such as the IOT.

Most websites’ accurate rating systems provide users with product and service ratings. User satisfaction has suffered as a result of a lack of faith and the manipulation of data. Because it communicates with existing accurate rating systems, all score statistics are saved on a central server. As a result, the manager has the ability to remove, all rating data that must be modified and manipulated in order to sway positive feedback on the service or product provider. As a solution to all of the shortcomings of current systems, an accurate rating system based on distributed ledger technologies is proposed in this chapter. Decentralized distributed ledger, with no institution attempting to centralize them. Distributed ledger technologies come in a variety of flavours. Blockchain technology Because it supports smart contracts, it was used in the proposed rating system. The Ethereum platform became selected from among numerous blockchain systems with a public permission network for the proposed accurate rating system. Raters are not permitted to rate in this system unless they make a request to the gadget are permitted to participate in the correct product score process. The Ethereum platform is notable for its smart contract support, which is to be used to create Solidity’s rating contract. The TestNet blockchain, on the other hand, can be used in the rating system. Due to the high cost of this method. The proposed rating system was then tested. KeywordsAccurateBlockchainSmart contractDistributed ledger technologies

Businesses in the insurance sector use DLT technology to open transaction flows and make job efficiency better. Researchers verified that blockchain technology for reinsurance solves fraud and claim processing issues to produce efficient insurance services. We examine how blockchain technology optimizes reinsurance contracts by combining insurance facts and blockchain pilot results using statistical procedures. Companies can complete insurance claims more rapidly at a 30% to 40% lower expense level while spotting 85% of possible fraud. Using this service reduces business expenses and processes run faster since it manages settlements directly plus records all system activities. Significant insurance companies like B3i, IBM, Swiss Re and Etherisc test blockchain-based reinsurance systems in their projects. Bitcoin offers benefits to the industry but users encounter three main difficulties due to unclear rules regarding transactions, several control limitations, and problems with integrating legacy systems. Through scientific data we learn that Distributed Ledger Technology provides dependable partnership programs to reinsurance through a trusted central platform. With fraud-resistant technology from blockchain systems the reinsurance and retrocession industry will develop better protection at lower prices and improved trustworthiness.

Applying blockchain technology to the Internet of Things (IoT) environment can significantly enhance the privacy protection of information and enable trusted sharing of data. However, the classic Proof-based blockchain systems have problems, such as unsatisfactory system throughput, low-consensus efficiency, and excessive computing resource consumption, making it difficult to directly apply them to the IoT environment. The recently proposed distributed ledger technology (DLT) represented by Tangle is designed based on the logical structure of the directed acyclic graph (DAG), which significantly improves the transaction confirmation delay and system throughput, making it more suitable for IoT scenarios. This article focuses on the performance and security of Tangle DLT in IoT applications with network instability. Such an unstable network environment can be caused by the predefined node working mode or signal interference, which leads to the status switching between online (work-mode) and offline (sleep-mode) of nodes or unstable data transmission. First, a Markov-chain-based model is established to analyze the time delay of block propagation in the underlying network under different status switching rates, different generation rates of blocks, different nodes’ average uplink bandwidths, and different number of neighbor nodes. Next, the impact of block propagation delay on the consensus efficiency and system throughput is analyzed. Furthermore, we also analyze the influence of block propagation delay on the attacker’s decision to conduct a double-spending attack under different network load, and deduce the suitable moment for the attacker to broadcast the parasite chain to maximize the probability of successful attack. Finally, through detailed numerical simulations, the experimental results comprehensively reveal the performance and security of the Tangle system in the unstable network environment. This article provides a valuable reference for the deployment and performance improvement of Tangle DLT in practical scenarios.
