Condition Based Monitoring

Conventional railway operations employ specialized software and hardware to ensure safe and secure train operations. Track occupation and signaling are governed by central control offices, while trains (and their drivers) receive instructions. To make this setup more dynamic, the train operations can be decentralized by enabling the trains to find routes and make decisions which are safeguarded and protocolled in an auditable manner. In this paper, we present the case study findings of a first-of-its-kind blockchain-based prototype implementation for railway control, based on decentralization but also ensuring that the overall system state remains conflict-free and safe. We also show how a blockchain-based approach simplifies usage billing and enables a train-to-train/machine-to-machine economy. Finally, first ideas addressing the use of blockchain technology as a life-cycle approach for condition-based monitoring and predictive maintenance in train operations are outlined.

For a citizen, voting is the fundamental tool to bring change in the country for good governance, through electing suitable candidates or a party to give them the power to govern. There are many forms of elections be it in the democratic or monarch systems. Each way, the vote has the power to elect the next people’s representatives. For a long time, paper-based voting was the only system being used globally for years; after the dot-com bubble, many countries emerged with electronic voting. But the problems such as security, transparency, and integrity of elections and the voting process are still under question. The issue with paper-based voting was accessibility, voter turns around and tallies, electronic voting has its own advantages and disadvantages such as a single point of failure, trustful systems, and loopholes to forge the electronic voting systems to alter the outcomes. To solve the problems related to the electronic voting process security, integrity, and transparency, an advanced approach is required to adopt. With the advancement of technologies, 4th industry revolution technologies give us Blockchain, Distributed Ledger and Smart Contract types of technologies which may be beneficial to solve the current problems in electronic voting systems. In this paper, we proposed a research-based case study to implement Decentralized Electronic Voting using Smart Contracts (DEV-SC) to solve security, transparency, and integrity-related problems available in the electronic voting process. This will ensure and enhance the voting process easily, trustable, and verifiable.

The promising power-to-gas (P2G) technology makes it possible for wind farms to absorb carbon and trade in multiple energy markets. Considering the remoteness of wind farms equipped with P2G systems and the isolation of different energy markets, the scheduling process may suffer from inefficient coordination and unstable information. An automated scheduling approach is thus proposed. Firstly, an automated scheduling framework enabled by smart contract is established for reliable coordination between wind farms and multiple energy markets. Considering the limited logic complexity and insufficient calculation of smart contracts, an off-chain procedure as a workaround is proposed to avoid complex on-chain solutions. Next, a non-linear model of the P2G system is developed to enhance the accuracy of scheduling results. The scheduling strategy takes into account not only the revenues from multiple energy trades, but also the penalties for violating contract items in smart contracts. Then, the implementation of smart contracts under a blockchain environment is presented with multiple participants, including voting in an agreed scheduling result as the plan. Finally, the case study is conducted in a typical two-stage scheduling process—i.e., day-ahead and real-time scheduling—and the results verify the efficiency of the proposed approach.

Sustainable Business Models

PurposeThe objective of this study is to deepen how blockchain technology through smart contracts can support the development of sustainable business models (SBMs). Particularly, the authors aim to determine the key elements enabling SBMs by applying smart contracts.Design/methodology/approachThe research context focusses on the case study of SmartInsurance, which is a fictitious name for a start-up in the insurance sector and the real name of which is not to be revealed. The start-up was able to collect 18m euros in 80 s in a crowdfunding operation, using smart contracts and a revolutionary business model. Internal as well as external documents of different sources are analysed and coded to gather information about the company, its values and its business and what it pursues with employing blockchain technology.FindingsThe results show how smart contracts can reduce the costs of transactions, increase social trust and foster social proof behaviours that sustain the development of new SBMs.Originality/valueThis study contributes to both the transaction cost theory and social proof theory, showing how new technologies such as the blockchain can provide a fresh perspective to support the development of SBMs.

The Impact

Abstract While blockchain technology is commonly considered potentially disruptive in various regards, there is a lack of understanding where and how blockchain technology is effectively applicable and where it has remarkable practical effects[1]. Against this background, we present and discuss a case study at length on the impact of this technology in the concrete setting of small short-term loans in retail banking. We propose to banks a robust and scalable blockchain technology with proof of stake and limited energy consumption used to streamline their processes, resulting in lower transaction and administration costs. This is made possible by smart contracts. Thereby, we facilitate small scale lending at high frequencies and short-term duration as well as an easier and more efficient way to connect small borrowers and lenders.
