SISTR
A protocol for a truly decentralized and sovereign identity.
Taking advantage of the disarming simplicity and versatility of the Nostr protocol, which is paving the way for a potentially genuine re-decentralization of the web, SISTR presents itself as a complement to the protocol and a set of specifications describing direct interactions between users and third parties (service providers, access, etc.) without any transmission of private information being necessary to prove the right (to access services, etc.) and/or the legitimacy of the interaction.
In short, it is a way of doing identity that is truly decentralized, sovereign and independent of any form of governance, and protecting the user's privacy.
