To convert plain text messages into ciphertext, a public key is a string of alphanumeric letters. Peer-to-peer transactions can be carried out using a public key without disclosing the details of one's private keys. Without the aid of a third party, it enables a safe and secure exchange of assets and information. They can maintain public access to this key. Given that they are mutually generated utilizing sophisticated asymmetric algorithm systems, all private keys are linked to a specific public key. That's why no one can obtain a user's private key simply by knowing their public key.
A feature that decrypts the private key to grant access is called a public key. In the world of cryptocurrencies, you can get tokens using a public key, and you can verify your ownership of the tokens you receive using a private key.
