Decentralized identity solutions in crypto
Decentralized identity (DID) solutions in crypto have become a crucial aspect of the Web3 ecosystem in 2024, enabling users to maintain control over their personal data while interacting with decentralized applications (dApps), services, and platforms. Unlike traditional identity systems that rely on centralized authorities, DID solutions offer self-sovereign identities (SSIs), giving users the ability to manage their identities securely and privately across multiple platforms without relying on a single, centralized entity.
Here’s an overview of some key decentralized identity solutions in crypto:
1. Ethereum Name Service (ENS)
