One wallet address only corresponds to one private key which cannot be modified. This private key belongs to the unencrypted private key of a 64-bit character string.

Once the wallet is created, enter the password to export the private key. Meanwhile, the income generated by mining can also be withdrawn from the pool to your own bitcoin address.Įxample of bitcoin address(from Address on Bitcoin Wiki): Anyone can transfer bitcoin to you through the bitcoin address. The bitcoin address is like a bank card number which represents your bitcoin account. Since the public key is too long, the bitcoin address came into being so as to not to expose the public key. The signature can verify the public key without revealing the private key. The mathematical relationship between them makes it possible for the private key to generate a signature for specific message. The public key is used to receive bitcoin while the private key is used for transaction signatures when bitcoin is paid. In the bitcoin system, a key corresponds to a private key and a unique public key derived therefrom. The public key is generated by the algorithm calculation of elliptic curve multiplication (K = k * G, where k is the private key, G is the constant for point generation and K is the resulting public key), which is known as the bitcoin address in a real sense. Private key only aims to back up and restore wallet information.Įxample of private key(from Private key on Bitcoin Wiki):Į9873D79C6D87DC0FB6A5778633389_SAMPLE_PRIVATE_KEY_DO_NOT_IMPORT_F4453213303DA61F20BD67FC233AA33262 Private key will not be needed for transfer, just your wallet password will be enough. It’s equivalent to the bank card password which can be reset and only known by yourself and the private key is randomly generated. Private key is essentially made of a random number, or an array of 32 bytes, 1 byte equals 8 bits of binary and a binary has only two values: 0 or 1, so the total number of private keys is nearly 2 (8 * 32) = 2256. With the private key, we can generate the public key and bitcoin address to spend the bitcoin at corresponding address. Public key and bitcoin address are both generated by private key, so we only need to save the private key. In this issue, we will explain the difference and operations of public key, private key and bitcoin address.
