What is Public Key?

Public Key

Public Key is a key that is disclosed to a third party in the process of transferring bitcoins.

It is a pair of a “private key,” which is known only to a specific person, and a “public key,” which is disclosed to the outside world. The public key is generated based on the private key, but it is not possible to know the private key from the public key.

In a Bitcoin transaction, the owner of the coin signs it using the private key, and a third party can verify the transaction using the signature and the public key.
