>Imagine a world where you are in direct control of your personal information; a world where you can limit and control how much information you share while retaining the ability to transact in the world. This is self-sovereign identity, and it is already here. Blockchain is the underlying technology paving the path to self-sovereign identity through decentralized networks. It ensures privacy and trust, where transactions are secure, authenticated and verifiable and endorsed by relevant, permissioned participants.

In 2005, [Kaliya Young](https://identitywoman.net/)[[**T**](https://twitter.com/IdentityWoman)], [Phil Windley](https://windley.com)[[**T**](https://twitter.com/windley)], [Drummond Reed](https://www.evernym.com/)[[**T**](https://twitter.com/drummondreed)][[**B**](https://equalsdrummond.name/)], and [Doc Searls](http://blogs.harvard.edu/doc/)[[**T**](https://twitter.com/dsearls)][[**B**](https://blogs.harvard.edu/doc)] hosted the first [Internet Identity Workshop](http://www.internetidentityworkshop.com/)(IIW)[[**T**](https://twitter.com/idworkshop)] in Berkeley to discuss "architectural and governance proposals for Internet-wide identity services and their underlying philosophies." -[Announcing IIW 2005](https://identitywoman.net/announcing-the-internet-identity-workshop-iiw2005/)
Since then, the IIW has met bi-anually, actively supporting the development of the identity software-ecosystem, including [OpenID](http://wiki.openid.net)('05), OpenID [2.0](http://wiki.openid.net/w/page/12995215/OpenID%20Authentication%202-1)('06), [OAuth](https://en.wikipedia.org/wiki/OAuth)('10), [FIDO](https://fidoalliance.org/)('13) and OpenID [Connect](https://en.wikipedia.org/wiki/OpenID_Connect)('14).
IIW participants began the effort towards creating a truly "[user centric identity](https://www.networkworld.com/article/2304596/access-control/what-is--user-centric--identity-.html)," in contrast to identity solutions whos focus has been fulfilling the needs of the enterprise. The pioneers of decentralized identity have long struggled against the "identity silo paradox," that while the [identerati](https://www.zdnet.com/article/the-identity-silo-paradox/) continually work on solutions to break up these silos, the enterprise has had a strong financial incentive to retain them.
