Format SEC 00305

This code represents the process of creating Bitcoin addresses from private keys. The code first hashes the public key using two hash algorithms: SHA-256 and RIPEMD-160. This action creates a unique hash of the public key. A network byte is then added to the public key hash to determine which network the address is being created for.

Message to the community from the creator: The final Bitcoin address is formed by combining the hash of the public key, the network byte and the checksum. The address is encoded in Base58 format for better human readability and displayed on the screen.
