## Decentralized Identifier

A Decentralized Identifier is a globally unique, persistent, and verifiable identifier that does not require a centralized registration authority. It is designed to be fully controlled by the user, providing a foundation for self-sovereign identity in decentralized systems.

In financial applications, these identifiers allow participants to establish reputation and credit history across multiple protocols without relying on a single service provider. They are cryptographically verifiable, ensuring that the identity linked to a wallet address is authentic and owned by the entity claiming it.

This removes the risk of central points of failure in identity management and facilitates secure cross-chain interactions.
