This article discusses the implementation details of an identity management application using blockchain, MongoDB Stitch, and MongoDB Atlas. The application uses MongoDB Stitch's serverless platform to utilize various capabilities such as authentication models, flexible authorization rules, hosted logic, and third-party service integrations. MongoDB Atlas provides a scalable, resilient, and worldwide-distributed database with rich query and analytical language capabilities. Change Streams features allow for event-driven applications to filter relevant notifications, and built-in TLS and enterprise security features provide additional access control, auditing, and encryption. The application demonstrates the potential of blockchain in digital systems and showcases how MongoDB enables rapid innovation, developer productivity, and scale-out for decentralized data control, trust, and immutability.
