Blockchain technology and BPMN (Business Process Model and Notation) hold great promise for revolutionizing a wide range of industries by improving transparency, security, and efficiency. In this paper, we propose an integration model for the systematic translation of any BPMN process into a Blockchain with smart contracts. Essentially, our approach aims to support smart contract practitioners working on complex business cases or those new to Solidity by simplifying the language and providing a clear, user-friendly path to translate business processes into effective Solidity code. Our model was applied in a real-world case study to streamline multiple-choice question (MCQ) creation and management in education. Finally, this paper discusses the potential impact of this integrated approach on educational assessment practices and suggests avenues for future research and development.
