The modern internet is built on identity systems controlled by third parties: Google, Facebook, Apple, or your employer. When you log in with these services, you are relying on their permission. If they revoke your access, you lose your digital identity. Decentralized Identity (DID) aims to give that power back to the user.
What is a DID?
A DID is an identity that is fully owned and managed by the individual, stored securely (often using blockchain or distributed ledger technology), and not dependent on any central authority.
Verifiable Credentials: Think of your driver’s license, degree, or professional certification as a cryptographically signed "credential" you hold in your digital wallet. You choose when and with whom to share it.
Zero-Knowledge Proofs: You can prove you are over 21 without revealing your actual birthdate or any other personal information.
The Self-Sovereign Internet
DID is the foundation for a truly "self-sovereign" digital life. It reduces the massive honeypots of personal data held by large corporations (a frequent target for hackers) and gives individuals granular control over their digital footprint.
