Decentralized identity (DID) systems shift control from corporations and governments to individuals. In 2026, this technology is becoming mainstream.
What is Decentralized Identity?
Instead of relying on Facebook, Google, or government agencies to verify who you are, you control your identity credentials directly. You decide what information to share and with whom.
How It Works
Blockchain-based systems create immutable identity records. You cryptographically prove attributes (age, citizenship, education) without revealing unnecessary details.
Advantages
- True ownership of identity
- Privacy by design
- Frictionless identity verification
- No single point of failure
- Works across borders
- Reduces identity theft
Real-World Applications
Remote work onboarding, financial services access, healthcare data sharing, international travel.
Emerging Standards
The W3C is standardizing DIDs. Major tech companies and governments are exploring implementations.
