A public key is a core component of public key cryptography (also known as asymmetric cryptography), which is a type of cryptography that uses two keys, a public key and a private key.

The public key is made publicly available and is used to encrypt messages that are intended for a specific recipient.

The recipient can then use their private key, which is kept secret, to decrypt the message.

The public key is also used to derive blockchain addresses or wallets that are then used to send and receive coins on a network.
