Decentralized Identity Verification
Decentralized identity verification is a blockchain-based approach to identity management that gives users control over their personal information while enabling secure verification for financial services. This system uses cryptographic proofs and distributed ledger technology to create portable, verifiable credentials without relying on centralized identity providers.
How decentralized identity verification works
Decentralized identity verification operates through a combination of blockchain technology, cryptographic proofs, and verifiable credentials. Instead of storing personal data in centralized databases, information is tokenized and controlled by users through digital wallets.
The system enables selective disclosure, allowing users to prove specific attributes (age, location, accreditation status) without revealing unnecessary personal information.
