## Identity Layer Protocols

Identity layer protocols provide the infrastructure for managing and verifying user identities in a decentralized and privacy-preserving manner. These protocols enable users to own and control their digital credentials, which can then be used to prove eligibility for financial services or to meet compliance requirements.

By separating identity verification from the core financial protocol, these layers allow for modular compliance where users can selectively share information. This is particularly important for institutional access to decentralized finance, where know-your-customer and anti-money laundering checks are mandatory.

Identity layer protocols utilize decentralized identifiers and verifiable credentials to establish trust without relying on centralized intermediaries. They facilitate a more secure and efficient onboarding process, reducing the burden on both users and service providers.

As the digital asset landscape matures, these protocols are becoming the standard for managing user reputation and access rights in a trustless environment.
