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.

Self-Sovereign IdentityDecentralised Identity

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 theβ€―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.
