Overview
Self-Sovereign Identity (SSI) is the ultimate goal of decentralized identity. It is a philosophy and set of technologies that ensure individuals are the sole owners of their digital presence, independent of any government or corporation.
Core Principles
- Existence: Users must have an independent existence.
- Control: Users must control their identities.
- Access: Users must have access to their own data.
- Transparency: Systems and algorithms must be transparent.
- Portability: Identities and data must be transportable.
Implementation
SSI is typically implemented using DIDs and Verifiable Credentials, allowing users to store their identity data in a 'digital wallet' on their own device.
