This article aims at introducing a new process-centric, trusted, configurable and multipurpose electronic voting service based on the blockchain infrastructure. The objective is to design an e-voting service using blockchain able to automatically translate service configuration defined by the end-user into a cloud-based deployable bundle, automating business logic definition, blockchain configuration, and cloud service provider selection. The architecture includes process mining by design in order to optimize process performance and configuration. The article depicts all the components of the architecture and discusses the impact of the proposed solution.
