Interoperable identity systems are a fascinating application for decentralized identity and credential frameworks. The main objectives of interoperable identity include:

(i) Empowering users with control over their data [reducing dependence on centralized entities] (ii) Facilitating seamless access across platforms [eliminating the need for multiple logins] (iii) Enhancing privacy and security [through cryptographic proofs and decentralized verification] (iv) Supporting diverse real-world applications [finance, healthcare, education, etc.]

These goals align closely with what decentralized identity solutions (e.g., DID standards, verifiable credentials) aim to achieve. Real-world use cases are already emerging:

In finance, interoperable identities streamline KYC processes while preserving user privacy.
In healthcare, they enable secure sharing of medical records across providers.

In education, they allow for portable, verifiable credentials for students.
The market potential is significant, with the global digital identity solutions market projected to reach $33 billion by 2025. For developers and organizations building identity solutions, focusing on interoperability is key to unlocking the full potential of digital identity systems in an increasingly connected world.
