## Self Sovereign Identity

Self Sovereign Identity is a model for digital identity where the individual or entity has sole ownership and control over their identity data. It removes the reliance on central providers or platforms that might otherwise gatekeep access to financial services.

In the context of DeFi, this empowers users to carry their reputation and credentials across multiple platforms seamlessly. SSI leverages blockchain technology to anchor identities in a way that is immutable and verifiable.

This paradigm shift allows for more user-centric financial applications where the individual is the ultimate arbiter of their data. It is a critical component in building a truly decentralized and permissionless financial ecosystem.
