1. bitcoin uses elliptic curve algorithm to generate public key and private key, and chooses secp256k1 curve. The generated public key is a 33 byte large number, and the private key is a 32 byte large number. The wallet file wallet.dat directly stores the public key and private key. The bitcoin address we use when receiving and sending bitcoin is obtained after the public key is processed by the algorithm. The specific process is that the public key is first processed by SHA-256 algorithm to get 32 byte hash result, then processed by ripemed algorithm to get 20 byte summary result, and then the address we see is obtained through the character conversion process. This character conversion process is the same as that of the private key. The steps are as follows: first, add the version number to the input content (the summary result of 20 bytes for the public key and the large number of 32 bytes for the private key). After two successive SHA-256 algorithms, take the first 4 bytes of the hash result of the last time as the check code and attach it to the back of the input content, and then encode it with base58, Get the string.
