Towards a Framework to compare Blockchain Platforms for Smart Contracts

Blockchain technology represents an innovation from both a structural and an application point of view. Since its inception, it has undergone a strong and fast development and, thanks to the implementation of smart contracts, it has been applied in different application contexts, such as business, healthcare, manufacturing, IoT applications and much more. The interest around blockchain has brought to the definition of several blockchain platforms facilitating their development and application. Thus, to choose the blockchain platform that is more suitable to support a specific business need is a strategic problem. This paper proposes an evaluation framework, i.e. a set of quality attributes, to characterize and compare the different blockchain platforms helping to identify the most suitable one.
