  Public and private keys are essential components of digital currency security. When a user wants to send a transaction, they use their private key to sign the transaction, which ensures that only they can authorize the transfer. The public key, on the other hand, is used to verify the authenticity of the transaction. By encrypting the transaction with the private key and decrypting it with the corresponding public key, the recipient can confirm that the transaction was indeed authorized by the sender. This cryptographic process ensures the integrity and security of digital currency transactions.

  Public and private keys are like the lock and key of digital currencies. The private key is kept secret by the user and is used to unlock and authorize transactions. The public key, on the other hand, is freely shared with others and is used to verify the authenticity of transactions. When a transaction is sent, it is signed with the private key, creating a unique digital signature. This signature can only be verified with the corresponding public key, ensuring that the transaction is legitimate and has not been tampered with. This system of public and private keys adds an extra layer of security to digital currencies, making them resistant to fraud and unauthorized access.
