This is a gathering of educational materials around decentralized, self-sovereign, and blockchain identity. Its an index for research, training, developers, students, end-users, investors, and the enterprise to more easily learn and navigate the decentralized identity landscape.
**NOTE: This repository is in the process of restructuring, along its way to [decentralized-id/decentralized-id.github.io](https://github.com/decentralized-id/decentralized-id.github.io), to become a community developed website [decentralized-id.com](https://decentralized-id.com).**

>A good self‐sovereign identity system will allow individuals to directly influence how companies, governments, and others correlate our interactions across different services and locations by default. It won’t fix all identity problems nor preclude alternative identity approaches, but it will put the individual in control of most uses of identity and give organizations a simpler, easier, more ethical way to use identity to improve how they provide services and products. When successful, it will not only enable individuals to exercise greater control over how companies and governments keep track of us, it will also illuminate those situations where self‐sovereign identity is restricted, facilitating a conversation about when and where such limits are appropriate.

The essence of Decentralized-ID is to create systems for identification that are not owned by any one particular organization, and global collaboration in support of interoperability among emerging technologies for identity.
It's impossible to have a conversation about decentralized-id without discussing blockchain and self sovereign identity:
* Blockchain fueled longstanding efforts to create a privacy preserving internet-wide identity protocol, and inspired development of decentralized networks for online identification.
* Self Sovereign Identity principles (with some help from the GDPR) have helped to shape the narrative around putting the identity owner in control over their personal information.
