Blocked-based Solidity — a Service for Graphically Creating the Smart Contracts in Solidity Programming Language

Abstract

In the last few years, we can observe a constantly increasing interest in systems and applications based on blockchain technology. Undoubtedly, this fact was significantly influenced by the introduction of the smart contracts mechanism that is one of the most popular features of blockchain nowadays and can be used across almost any industry. Smart contracts are programs stored on a blockchain that run when predetermined conditions are met. Since programming smart contracts is not trivial, this paper proposes a service that enables their creation by constructing diagrams from graphical blocks. The diagrams are then transformed into a smart contract code written in the Solidity language. The paper presents the general idea of the proposed service and selected use cases illustrating its application.
