Public Key

A public key is a cryptographic code used in conjunction with a private key to encrypt and decrypt data. In the context of cryptocurrency, a public key is associated with a wallet address that allows others to send funds to it. Unlike private keys, public keys can be shared openly without risking the security of the user's funds. The relationship between the public and private key ensures that only the holder of the private key can access the funds linked to the public key. Example: A Bitcoin user shares their public key with others to receive Bitcoin payments, while their private key remains secure to authorize transactions.
