A public key is a component of an asymmetric key pair in cryptographic systems. It is openly shared and serves as an identifier and means for verifying digital signatures and encrypting messages.
While widely shared, a public key cannot be used to derive the corresponding private key, safeguarding the security of digital interactions. It serves as a recipient address for transactions and allows verification of digital signatures.
The public key’s importance lies in facilitating secure transactions, ensuring that funds are sent to the correct recipient address, while the associated private key retains exclusive control over those funds’ access and usage.
