Special Issue Information

Dear Colleagues,

Blockchain and distributed ledger technologies have established themselves well in diverse social and business areas. There are numerous applications of blockchain technology in value and supply chain, fintech, social systems, industry 4.0, IoT, open-source development, and many others. Blockchain technology is disrupting well-established business models. However, contemporary blockchain systems rely heavily on the server-side infrastructure and this limits some of the potential uses. The next technological frontier is the adoption of blockchain technology by the wider community of consumers and expanding business cases by utilizing mobile and portable devices. Mobile blockchain research needs to address many unresolved issues related to mobile connectivity, consensus, identity, and Sybil attacks; however, the penetration potential and impact that blockchain technology could have on mobile applications can be truly disrupting. Mobile and decentralized trust applications without the need for heavy server-side infrastructure are predicted to have a huge impact on the blockchain space in the upcoming years. 

This Special Issue focuses on mobile blockchain technology and mobile applications that run on mobile and portable devices. We encourage researchers and practitioners that work in the mobile blockchain space to share their problems and solutions, as well as mobile and decentralized applications that utilize blockchain technology.

Bitcoin’s APIs in Open-Source Projects: Security Usability Evaluation

Given the current state of software development, it does not seem that we are nowhere near vulnerability-free software applications, due to many reasons, and software developers are one of them. Insecure coding practices, the complexity of the task in hand, and usability issues, amongst other reasons, make it hard on software developers to maintain secure code. When it comes to cryptographic currencies, the need for assuring security is inevitable. For example, Bitcoin is a peer-to-peer software system that is primarily used as digital money. There exist many software libraries supporting various programming languages that allow access to the Bitcoin system via an Application Programming Interface (API). APIs that are inappropriately used would lead to security vulnerabilities, which are hard to discover, resulting in many zero-day exploits. Making APIs usable is, therefore, an essential aspect related to the quality and robustness of the software. This paper surveys the general academic literature concerning API usability and usable security. Furthermore, it evaluates the API usability of Libbitcoin, a well-known C++ implementation of the Bitcoin system, and assesses how the findings of this evaluation could affect the applications that use Libbitcoin. For that purpose, the paper proposes two static analysis tools to further investigate the use of Libbitcoin APIs in open-source projects from a security usability perspective. The findings of this research have improved Libbitcoin in many places, as will be shown in this paper. Full article
