Conventional web services have been designed based on an architecture in which data is stored and controlled on servers in the cloud. The services are accessed from users’ ICT devices such as PCs and smart phones that act as clients. This widely accepted architectural paradigm will be shifted by an adversative approach. Emergent technologies, self-sovereign identity and blockchain, can contribute to form a decentralized architecture that makes conventional servers unnecessary. This makes it possible to realize a self-sovereign service in which users can store their credentials locally and transmit them to service providers on their own initiative. To realize this paradigm, this article elaborates on an architecture and service design that gradually shift from centralized mechanisms of authentication and authorization to a distributed architecture of Web3.
