  Blockchain ensures secure identity management in digital currencies by utilizing its decentralized and immutable nature. Each user is assigned a unique cryptographic key that acts as their digital identity. This key is stored on the blockchain, making it tamper-proof and resistant to unauthorized changes. Whenever a user wants to perform a transaction, their digital identity is verified by the blockchain network, ensuring that only authorized individuals can access and transfer funds. This eliminates the need for centralized identity management systems, reducing the risk of identity theft and fraud.

  With blockchain, secure identity management in digital currencies is achieved through the use of public and private key cryptography. Each user has a pair of keys: a public key, which is visible to everyone, and a private key, which is kept secret. When a user wants to initiate a transaction, they use their private key to sign the transaction, proving their identity. The blockchain network then verifies the signature using the user's public key, ensuring that the transaction is legitimate. This cryptographic process ensures the security and integrity of identity management in digital currencies.
