>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.
* The United Nations Sustainable Development Goals (SDGs) have also helped to shape the narrative and further fueled efforts for a global and widely accessible identity solution.

>"[This paper](http://asn.planetwork.net/asn-archive/AugmentedSocialNetwork.pdf) proposes the creation of an Augmented Social Network (ASN) that would build identity and trust into the architecture of the Internet"
Ideas from the ASN were the foundation of much that followed.

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](https://www.zdnet.com/article/the-identity-silo-paradox/)," that while the *identerati* continually work on solutions to break up these silos, the enterprise has had a strong financial incentive to retain them.

Evident from the other [whitepapers](https://github.com/WebOfTrustInfo/ID2020DesignWorkshop/blob/master/topics-and-advance-readings/README.md) submitted to the second RWoT Workshop, the DID identifier had begun to emerge:
>"Decentralized Identifiers (DID) stored in a permissioned blockchain enable principals to directly control their own identities with cryptographic proofs and secure, addressable network endpoints. DIDs further enable a Decentralized Identity Management (DIDM) infrastructure that will empower people and organizations to securely and confidentially manage and assert their identities."

Our thesis is that blockchains, or more generically distributed ledgers, are a potentially powerful new tool for “identity roots” — the starting points for an Internet identity. However “blockchain identity” may not fully address the core security and privacy principles needed in a complete identity system. In this case DIDs — Decentralized Identifiers rooted on a distributed ledger — may end up being a foundational building block for higher level identity management solutions. -
