Decentralized Identifiers (DIDs) are a critical component of the Web3 ecosystem, designed to provide users with self-sovereign identity and full control over their digital identities. DIDs are unique, globally unique identifiers that enable individuals to interact and transact across various platforms and services while maintaining ownership of their identity information. They are built upon the principles of decentralized systems, ensuring that no single authority or central entity governs or controls the creation and management of DIDs.

Key features of DIDs include:

1. Decentralization:

DIDs are decentralized by design, meaning they are not tied to any specific centralized entity or authority. Instead, they are created and managed using decentralized technologies like blockchain or distributed ledger systems, ensuring no single point of failure and offering greater resilience against security breaches.

2. Self-Sovereign Identity:

With DIDs, individuals have true ownership and control over their identity information. They can selectively share specific attributes or personal data with different service providers or platforms without compromising their overall identity.

3. Interoperability:

DIDs are interoperable across various systems, platforms, and applications. This means that users can use the same DID across different services, streamlining the process of accessing and utilizing services without the need for creating multiple accounts.

4. Privacy and Security:

DIDs prioritize user privacy and security. Personal data and sensitive information are not stored in centralized databases, reducing the risk of data breaches and unauthorized access.

5. Verifiable Credentials:

DIDs can be linked to verifiable credentials, allowing users to present proof of specific attributes or qualifications without revealing unnecessary personal data. This feature enhances user privacy and enables trustless interactions.

DIDs in Web3-based systems fosters a self-ownership approach.

In the context of mobile communications, DIDs play a crucial role in projects like Jellyfish Mobile. By replacing traditional mobile numbers with DIDs associated with Web3 wallet addresses, users gain full ownership and control over their mobile identity, reducing the risk of security breaches like SIM swapping attacks. The use of DIDs in Web3-based systems fosters a user-centric, decentralized mobile ecosystem, where individuals can securely interact with various services and applications while preserving their privacy and data ownership.
