Abstract

Programming is not a simple task. Besides, the learning of syntax, the obstacles often seem insurmountable for the beginner. Syntax errors frustrate and distract attention from the actual algorithms and logic that need to be understood. With the help of visual programming, syntax errors can be avoided as much as possible by using predefined graphical boxes, which, due to their shape, can only be connected correctly to form a program. Moreover, Smart Contracts are mainly designed to exclude the need to trust a third party. Here using Visual programming makes perfect sense by making the creation of Smart Contracts much simpler without the help of a developer. Another advantage of Visual Programming Language (VPL) in Smart Contract creation is that the terms and conditions in Contracts can be read and understood from non-developers. In this research we aim to implement a Visual Smart Contract Creator and to conduct an empirical evaluation, which on the one hand, measures the semantic understandability of a visual representation of a Smart Contract created with our tool and compares it to its textual representation in Ride programming language. On the other hand, we evaluate the user acceptance of the tool.
