Blockchain technology has gained significant interest across various industries including finance, business applications, Smart Cities, and the Internet of Things (IoT). As organizations increasingly recognize blockchain’s strategic importance, interest in its adoption has surged, viewing it as a critical growth element. However, challenges such as integration with existing systems, security concerns, regulatory uncertainties, and a lack of expertise hinder its adoption. A major barrier is the reluctance to replace or adapt current systems, leading to technical debt. With an increasing amount of blockchain platforms and cryptocurrencies, selecting the right platform is daunting and requires a comprehensive knowledge of functionality, adaptability, and compatibility. Existing methodologies help to decide when to use blockchain but do not address platform selection. In response, we propose BlockPS—a Blockchain Platform Selection methodology designed to streamline the distributed application development process. BlockPS integrates seamlessly with existing software development processes, aiding in blockchain adoption while minimizing technical debt in just 3 steps that software developers can follow.
