Industrial blockchain applications have recently risen to the top of the scientific and industrial communities' priority lists. This is due to their practical capabilities in resolving many issues in various industrial domains. Visibility and traceability to a large volume of trusted data benefit members of a consortium of industrial companies and associated organizations. Data scientists who query data and use statistics and Machine Learning to solve a wide range of interesting problems benefit as well. This paper introduces a blockchain application Query Engine based on upgradable Smart Contracts with a lightweight, flexible, and interoperable query framework. This query engine specifically is designed to facilitate the storage and querying of application data recorded on blockchain networks. © 2021 IEEE.
