Public key

Part of a cryptographic key pair used in asymmetric cryptographic systems such as cryptocurrencies. It is used for security, authentication and data encryption. The public key is distributed openly and is available to all users. In a key pair, the public key matches the private key, and data encrypted with the public key can only be decrypted using the corresponding private key. Public keys play an important role in ensuring security and secure transactions in cryptocurrency networks and other cryptographic systems.
