Self-sovereign Identity paradigm refers to identities owned by people themselves without depending on centralized systems or organizations.
Facebook, Twitter, LinkedIn, GitHub are all centralized identity platforms. Identities created by these platforms are not exportable or usable across apps. Not in user’s control.
Self-sovereign Identity (SSI) is about getting users the control on their identity using decentralized systems.
Users create and own their identities on blockchains. They prove ownership using cryptographic signatures. They hold private and PII data in their identity wallets. They could use their identity across several app without copying or creating them again and again. At any time, they could stop sharing their data.
