The debate around digital identity is fraught with tension. Until now, most systems have operated under centralized models (such as Google or Facebook) or federated models, where a single authority concentrates the power to issue and validate.

This leaves users vulnerable: data is being used without permission, there are single points of failure, and slow processes that generate distrust and rising cybersecurity costs.

In this context, for almost five years since its founding, an interesting proposal, a new concept, has been developed: Self-Sovereign Identity (SSI). It emerges as a model that gives people control over their digital identity.
