Since the emergence of the Bitcoin cryptocurrency, the blockchain technology has become the new Internet tool with which researchers claim to be able to solve any existing online problem. From immutable log ledger applications to authorisation systems applications, the current technological consensus implies that most of Internet problems could be effectively solved by deploying some form of blockchain environment. Regardless this ‘consensus’, there are decentralised Internet-based applications on which blockchain technology can actually solve several problems and improve the functionality of these applications. The development of these new blockchain-based solutions is grouped into a new paradigm called Blockchain 3.0 and …

Millions of Bitcoin transactions occur daily, worth nearly $2 billion annually. With the proliferation of cryptocurrency markets, the reluctance to adopt the currency as an alternate payment method could cause businesses to forgo growth opportunities within this expanding market. Grounded in the diffusion of innovation theory, the purpose of this qualitative multiple-case study was to explore strategies business leaders use to respond to the alternative payment concerns perpetuated by cryptocurrency markets. The participants comprised 6 business leaders who effectively employed cryptocurrency adoption strategies. Data were collected through semistructured interviews, corporate documents, and other company social media resources. Thematic analysis of …

Blockchain technology has gained prominence over the last decade. Numerous achievements have been made regarding how this technology can be utilized in different aspects of the industry, market, and governmental departments. Due to the safety-critical and security-critical nature of their uses, it is pivotal to model the dependability of blockchain-based systems. In this study, we focus on Bitcoin, a blockchain-based peer-to-peer cryptocurrency system. A continuous-time Markov chain-based analytical method is put forward to model and quantify the dependability of the Bitcoin system under selfish mining attacks. Numerical results are provided to examine the influences of several key parameters related to …
