Blockchain-powered decentralized identity management provides consumers with authority over their personal data and increases online company privacy, security, and interoperability. Traditional identity systems are administered by governments or enterprises. Blockchain, on the other hand, empowers users in its decentralized identity management. Blockchain records transactions and data across computers. Cryptographically linking each transaction, or “block,” creates an immutable chain of information. Decentralized and tamper-resistant blockchain is ideal for secure and transparent identity management. Decentralized identity management systems create and manage digital IDs by using cryptography. Blockchain secures their identities. Selectively sharing names, ages, and addresses with numerous service providers avoids providing unnecessary personal information. Decentralized identity management leads to self-sovereignty. Individuals can manage their identities without intermediaries. Controlling data access prevents identity theft, fraud, and misuse. Interoperability improves with decentralized identity management. The Decentralized Identity Foundation (DIF) and World Wide Web Consortium (W3C) verifable credentials (VCs) make verifying and sharing digital identities across platforms, apps, and organizations easy. Blockchain secures identity management. Cryptography secures blockchain transactions and identities. Blockchain’s decentralized nature makes it more secure.
