Decentralized vs Self-Sovereign Identity
Difference between services and concepts
Decentralized and self-sovereign identities are closely related concepts, but they have some nuanced differences.
A self-sovereign identity is a specific approach within a decentralized identity that emphasizes individual control and ownership over personal identity data. Self-sovereign identity can be seen as a more advanced and user-centric manifestation of decentralized identity, emphasising privacy and autonomy.
Decentralized identity refers to implementing the SSI concept that supports managing identity in a decentralized manner by distributing ownership and access control through the different actors in the data verification transaction.
It reduces reliance on centralized identity and provides access to relevant data according to each party's needs.
Decentralized identity has been tested through different designs and implementations; nChain makes every effort to align with specifications approved and developed by W3C and EIDAS frameworks.
