  • Redefining early stage funding: exchange traded smart contracts   Order a copy of this article
    by Nipun Agarwal 
    Abstract: An early stage funding platform using cryptocurrency smart contracts can potentially provide an equity and debt capital raising platform for new ventures compared to crowdfunding, initial coin offerings (ICOs) and seed funding. The existing capital raising methods are less transparent, have limited depth of funding and less diversification. Utilising a cryptocurrency smart contract-based early stage funding platform will allow new ventures to obtain a staged funding environment, starting from seed funding. Each stage of funding can be represented by a smart contract that is aligned to a formal standardised legally binding contract between the venture and investors through the platform. Competition for funds and a transparent smart contract-based platform should allow free markets to price investments in the new venture in a more efficient fashion. Additionally, such a platform should provide more funding opportunities to new ventures that werent available prior.

  • Potential Applications of Smart Contract Technology in Subsidy Distribution (Source Code for Data Structures and Problem Solving Using Solidity)   Order a copy of this article
    by Armin Saatian 
    Abstract: The way governments distribute subsidies in terms of targeting and their effects on public economics has always been one of the biggest management challenges, especially in developing countries. The purpose of this research is to outline the application of blockchain technology in the context of the subsidies distribution through the transfer of digital currency; also, a blockchain-based targeted subsidy system has been performed under the Ethereum network using solidity language. The written program is based on a platform extracted from the library research method and through the research conducted over recent years. This study aims to achieve an intelligent, autonomous, and self-executing subsidy distribution system. Furthermore, this study can make it possible for governments to provide a subsidy payment platform that can prevent data manipulation due to its decentralised nature, create a more reliable method for subsidy payments, and increase transparency in the distribution of subsidies.

  • L7SP: A Layer Seven Service Provider for Private Blockchain Systems   Order a copy of this article
    by Fabrício Reis Furtado, Rodrigo Da Rosa Righi, Cristiano André Costa, Alex Roehrs, Madhusudan Singh 
    Abstract: The interest in blockchain technology has grown over the years and its potential was soon perceived for other applications beyond the Bitcoin due to its decentralization and immutability characteristics. The technology also has some limitations and technical challenges compared to centralized systems, especially in terms of performance and scalability. The current limitations prevent to use blockchain on a large scale for other types of applications, making studies necessary to address these gaps and evolve the technology. Considering this scenario, this paper proposes the L7SP model to work on private blockchain, giving contributions for performance gains, and system management improvement. L7SP provides an intermediate layer of services that allow faster transaction processing and online monitoring. The solution preserves the decentralization nature of blockchain, so maintaining compatibility with legacy systems. A prototype was implemented to evaluate the model and the results showed performance gains with the L7SP introduction.

  • Transforming healthcare with blockchain   Order a copy of this article
    by Prerna Singal, Garima Sharma, Sumanlata Gautam 
    Abstract: Sharing medical data with numerous stakeholders for varied purposes is a perplexing problem facing healthcare systems throughout the world. All this needs to be done, whilst ensuring patient and health data privacy and data integrity. Through this paper, an attempt has been made to present a novel distributed digital health record management system. The blockchain framework has been built using the tools provided by hyper ledger, an open source project. This system empowers patients with a comprehensive, secure, immutable, and easily accessible digital record of their health. Also, this information is available across multiple practitioners and healthcare providers throughout the world. This system can therefore empower the emergence of health data economics, empowering researchers with the health data and giving patients an opportunity to share their health data without losing anonymity. The purpose of this paper is to introduce a prototype of a health data management system utilising blockchain.

  • Portfolio performance analysis: a case study of cryptocurrencies   Order a copy of this article
    by Florin Aliu, Artor Nuhiu, Přemysl Pálka, Michaela Blahová 
    Abstract: The study measures the risk level linked with different portfolios of cryptocurrencies by using portfolio diversification techniques. Data on prices and trade volumes of cryptocurrencies were collected on a daily basis, from 2012 till 2018. Ten portfolios were constructed based on diverse types and numbers of cryptocurrencies. The results of the study confirm a negative relationship between the average number of cryptocurrencies and the average risk level of the portfolio. Involving more cryptocurrencies within the portfolio reduces the diversification risk of the portfolio. The average volatility and average correlation coefficient both drop when moving towards portfolios with more cryptocurrencies. Average returns stand against portfolio theories, where more risky portfolios offer less daily weighted average returns and the other way around. Outcomes of the study provide indications for the individual investors and financial institutions on the risk characteristic attached to the portfolio of cryptocurrencies.
