New Challenges

Industry 4.0 requires the cooperation of several technologies. The intersections of these technologies present us with new challenges. One of these challenges is identification, since we have to identify all the items that are on the network that do work and those that are worked upon. If we fail to identify one of these items the network is presented with an unidentified potentially malicious device or a misidentified product which can cause production to halt. Blockchains or otherwise known as Distributed Ledger Technology, DLT for short is a technology that builds upon the current bookkeeping paradigm and expands it in a decentralized direction. This however can be used in more than just banking since it is essentially a distributed database that has memory of past events not just the current state. By using a blockchain based distributed database to hold processing details and using RFID-s as keys to certain entries in the database it is possible to build a tamper proof production system that can handle the challenges of industry 4.0. It may also be possible to use blockchain technology as a form of digital paper trail that can be used to validate messages sent to the nodes of the system.

The global supply chain is a network of interconnected processes that create, use, and exchange records, but which were not designed to interact with one another. As such, the key to unlocking the full potential of supply chain management (SCM) technologies is achieving interoperability across participating records systems and networks. We review existing research and solutions using distributed ledger technology (DLT) and provide a survey of its current state of practice. We additionally propose a holistic solution: a DLT-based interoperable future state that could enable the interoperable, efficient, reliable, and secure exchange of records with integrity. Finally, we provide a gap analysis between our proposed future state and the current state, which also serves as a gap analysis for many fractional DLT-based SCM solutions and research.

Aim/Purpose: To understand the current state of the body of literature in blockchain technology and propose dimensions for acceptance. Background: Blockchain technology has large promise to replace centralized and even distributed database systems. Its premise focuses on issues such as transparency, immutability, and privacy of transactions. Created for bitcoin, researchers and practitioners have begun to see its potential in different areas and industries. Its acceptance is still debatable as there are a number of issues still to be resolved. Methodology: We conducted a literature review to assess the size and scope of the body of research in the are of blockchain applications and carried a conceptual analysis for blockchain acceptance. Contribution: We provide an assessment of the body of literature in the are of blockchain and cluster the number of articles according to application groupings. We show that research in blockchain cannot be considered that it even started due to its diverse, scattered and weak related studies. At the same time, blockchain is still faced with a lot of resistance yet no one is studying its acceptance. We therefore propose dimension for its acceptance, as adapted from the very rich area of ecommerce research. Findings: Body of research is at its infancy. Research is scattered and weak. Most research is related to bitcoin and cryptocurrency. There is a great need to study the application of blockchain outside its current focus on cryptocurrency. Areas of study of blockchain applications include internet of things, energy and finance – other areas are identified. Dimensions for blockchain acceptance are proposed and include: reputation, risk, usefulness, and intentions. Recommendations for Practitioners: Blockchain has great potential to be applied in areas such as medicine, aviation and disaster relief. In terms of blockchain characteristics, practitioners have a lot of room to innovate in various approaches such as the blockchain hashing algorithm, smart contracts and peer validation. These do not need to be fixed but can vary based on the business characteristics. Recommendations for Researchers: Research in the application of blockchain can be considered as not even started. The application of blockchain is an open playground which today few have stepped in to enjoy. Research opportunities include but are not limited to energy consumption of blockchain transactions, dimensions to blockchain adoption and acceptance, adaptability of blockchain to various industries, and innovation in blockchain characteristics such as new approaches to peer validation of transactions.

Distributed Ledger Technology

Distributed Ledger Technology (DLT) creates a decentralized system for trust and transaction validation using executable smart contracts to update information across a distributed database. This type of ecosystem can be applied to Commodity Trade Finance to alleviate critical issues of information asymmetry and the cost of transacting which are the leading causes of the Trade Finance Gap (ie. the lack of supply of capital to meet total trade finance demand). The possibility of scaling up such ecosystems with a number of Institutional Investors and micro small medium enterprises (MSME) would be advantageous, however, it brings up its own set of challenges including the stability of the system design. Agent-based modeling (ABM) is a powerful method to assess the financial ecosystem dynamics. DLT ecosystems model well under ABM, as the agents present a clearly defined taxonomy. In this study, we use ABM to assess the Aquifer Institute Platform - a DLT-based Commodity Trade Finance system, in which a growing number of participating parties is closely related to the circulation of utility tokens and transaction flows. We study the system dynamics of the platform and propose an appropriate setup for different transaction loads.

Blockchain for business is a new concept which enables many industries and organizations to implement even the basic of systems on foundation of blockchain technology. Using this technology, our goal is to develop a payments system that enables transfer of funds for a monetary transaction between two parties. Hyperledger is an open source community oriented effort which was made to propel cross-industry blockchain advances that were available. The Linux Foundation has it. It has partners from everywhere throughout the world , at a worldwide dimension and incorporates ventures like funding, banking, Internet of Things, supply chains, assembling and Technology. Using Blockchain for Enterprise technology, we are going to develop a new payments system that makes use of regulated cryptocurrency. Using this system, we want to create a new cryptocurrency specific to the payment portal for people to buy, sell and pay or earn rewards using this cryptocurrency. This system will majorly consist of participants and admins that will be divided based on the certificates assigned to every participant. Our implementation involves. using the fabric for creating a payment system run on the backend of blockchain technology. This will involve having a regulatory authority to maintain the cryptocurrency, ledger and authenticity of the users. Theoretically, the blockchain technology maintains anonymity for transactions. It uses a distributed ledger to record transactions for people to be able to make secure transactions without any repercussions. Blockchain for Enterprise implements Blockchain technology by using concepts like Trust, Privacy and Smart contracts in addition to the distributed ledger to create an industry friendly Blockchain business application. Blockchain is a rapidly growing field with multiple implementations which can be explored not just on anonymity but also on actual life implementations. Distributed ledger technology is applied to the payment systems. Cryptocurrency would now not only be used for anonymous transactions but also for regular day to day transactions.

Nowadays, there are a lot of new mobile devices that have the potential to assist healthcare professionals when working and help to increase the well-being of the people. These devices comprise the Internet of Medical Things, but it is generally difficult for healthcare institutions to meet compliance of their systems with new medical solutions efficiently. A technology that promises the sharing of data in a trust-less scenario is the Distributed Ledger Technology through its properties of decentralization, immutability, and transparency. The Blockchain and the Internet of Medical Things can be considered as at an early stage, and the implementations successfully applying the technology are not so many. Some aspects covered by these implementations are data sharing, interoperability of systems, security of devices, the opportunity of data monetization and data ownership that will be the focus of this review. This work aims at giving an overview of the current state-of-the-art of the Blockchain-based systems for the Internet of Medical Things, specifically addressing the challenges of reaching user-centricity for these combined systems, and thus highlighting the potential future directions to follow for full ownership of data by users.
