## Decentralized Identifier Protocols

Decentralized identifier protocols are frameworks that allow individuals to own and manage their own digital identities without relying on a centralized authority. These identifiers are stored on-chain or in decentralized storage, giving users full control over their personal data and how it is shared with third parties.

In a financial context, this allows for the creation of verifiable credentials that can be used across different platforms for KYC and compliance purposes. Instead of re-verifying identity at every exchange, a user can provide a portable, verified credential that is cryptographically signed.

This streamlines the onboarding process and improves the user experience while maintaining security. It is a foundational element for the development of sovereign, compliant, and interoperable digital identities.
