“…These domains have accrued thousands of datasets requiring a sustained throughput from blockchain, i.e., consistent number of transactions per minute. In the foreseeable future, there will arguably be a continuous requirement for blockchain-based applications which can continually handle large amounts of transactions per second [16].…”

This paper provides a performance evaluation of private blockchain networks based on Ethereum, an open-source blockchain platform. Different sectors with stringent blockchain security, privacy, and auditability requirements have adopted Ethereum private networks to keep their data exclusive within a permission group. However, the concrete performance of private Ethereum networks-i.e., transactions or smart contract interactions-has received limited attention. We have set an Ethereum private network to study the following configuration parameters: (1) distinct transaction complexity; (2) different block sizes; (3) two consensus algorithms, namely Proof-of-Work and Proof-of-Authority; and (4) multiple network nodes. Our evaluation has employed time series datasets from the pharma industry, where high levels of security, privacy, and auditability are always required. However, this evaluation approach is domain-agnostic being valid for other fields. We have observed an inverse correlation between the amount of transactions per block and the block period. In this context, we have determined linear models for the simple (low gas limit) and the complex transactions (high gas limit). The model enables to calculate the block period for a specific amount of transactions to be committed in a block. We also include predictive modelling for an optimal configuration taking into account the amount of transactions to commit into a blockchain network.

“…Blockchain is a shared ledger that is append-only, immutable, and secured [25] [26]. This shared ledger is maintained utilizing a distributed network of nodes [27] where these participating nodes called peers may have full or partial viewability of all the transactions in a blockchain. Blockchain is immutable in the sense that no participant can alter, tamper, or conceal a recorded transaction.…”

A Blockchain-Based Approach to Prevent Hidden Contagion of Covid-19

The unprecedented outbreak of COVID-19 has become a grave concern worldwide because of its highly infectious nature. Besides extensive research on developing vaccine or medicine to prevent this virus attack, many technology-based solutions are also getting more importance as no one knows till date how to put a full stop on it. Being first conceptualized in 2008, blockchain technology gained enormous popularity in the cryptocurrency domain. However, nowadays, blockchain has also become popular in the healthcare domain as a privacy-preserving and data authenticity technique. The primary goal of our experiment is to develop a framework which can utilize the features of permissioned blockchain and maintain the fully controlled sharing of confidential health record to exhibit the health status and COVID-19 history of a patient using a mobile QR code based solution. So, the administrative team of any public place can be aware of the health condition of any people who are using this platform to prevent the unaware and hidden contagion of COVID-19. This article is the first of its kind to propose such a method to aid in solving this crisis. In our experiment, we have shown that Hyperledger Fabric as a base technology along with a robust user registration algorithm and data accessibility can solve the problem under consideration with a minimal health record of the patient. The proposed architecture also offers the patient more control over the health record, where the healthcare service provider assures the authenticity of the data, and the intrinsic feature of the blockchain technology makes it immutable.

“…The construction industry is backward in terms of digitalization, and, as pointed out by Perera et al (2020), it is historically reported as one of the latest and most reluctant sectors (just above agriculture and hunting) to have adopted information technology. By conducting a systematic literature review and a deep analysis of Use Cases, they critically analyzed the potential impact of blockchain technology adoption in this sector, finding out that it can be able to mitigate the existing issues in the current construction systems.…”

Design of a Sustainable Blockchain-Oriented Software for Building Workers Management

et al. 2020

The building workers sector is one of the most challenging sectors for Human Resources (HR) management. In this work, we propose a solution relying on Blockchain technology and present the design of a Blockchain-Oriented Software system conceived for managing the building workers sector with a focus on workers' safety, and it is guided by sustainable and Agile Methodologies in software design. The proposed approach takes advantage of different features of the Blockchain technology and provides transparency for labor inspectors, grants data integrity and immutability, relies on tamper-proof time stamps for any recorded activity, allows the implementation of Smart Contracts where clauses are automatically respected without the need of a trusted control authority, acknowledges the legal requirements in the field, including the possibility of creating an Operational Safety Plans, which construction companies have to provide, and finally implements the creation of vacant job positions that workers can find and apply to. In order to achieve these goals, we adopt the Blockchain-Oriented Software Engineering (BOSE) methodology to design Blockchain software applications and apply an Agile methodology centered on Blockchain Software development (called ABCDE) for the design and development of the decentralized application. Such a methodology allows us to center the software development around the actors of the system in the specific domain, such as Building Workers, Construction Companies, Labor Inspectors, and so on. In addition, we rely on the software sustainability analysis, based on the five dimensions of sustainability, to evaluate the approach and to avoid mistakes in the system development. We design system elements with specific diagrams, and we divided our system in the on-chain and the out-of-chain components. The implementation of the system, done by using Ethereum and the ERC721 standard, allows us to improve some aspect of the design, to know the deployment and usage costs, and to evaluate the effect of the user interface. Finally, we discuss the effects of our system and its sustainability, and we provide a comparison of our system with a similar per aims but centralized system.
