比特币地址生成流程如下图所示：
第一步，随机选取一个32字节的数，大小介于1~0xFFFF FFFF FFFF FFFF FFFF FFFF FFFF FFFE BAAE DCE6 AF48 A03B BFD2 5E8C D036 4141之间，作为私钥
18e14a7b6a307f426a94f8114701e7c8e774e7f9a47e2c2035db29a206321725
第二步，使用椭圆曲线加密算法（ECDSA-SECP256k1）计算私钥所对应的非压缩公钥（共65字节，1字节0x04，32字节为x坐标，32字节为y坐标）。
0450863AD64A87AE8A2FE83C1AF1A8403CB53F53E486D8511DAD8A04887E5B23522CD470243453A299FA9E77237716103ABC11A1DF38855ED6F2EE187E9C582BA6
第三步，计算公钥的SHA-256哈希值
600FFE422B4E00731A59557A5CCA46CC183944191006324A447BDB2D98D4B408
第四步，计算上一步哈希值的RIPEMD-160哈希值
010966776006953D5567439E5E39F86A0D273BEE
第五步，在上一步结果之间加入地址版本号（如比特币主网版本号“0x00"）
00010966776006953D5567439E5E39F86A0D273BEE
第六步，计算上一步结果的SHA-256哈希值
445C7A8007A93D8733188288BB320A8FE2DEBD2AE1B47F0F50BC10BAE845C094
第七步，再次计算上一步结果的SHA-256哈希值
D61967F63C7DD183914A4AE452C9F6AD5D462CE3D277798075B107615C1A8A30
第八步，取上一步结果的前4个字节（8位十六进制数）D61967F6，把这4个字节加在第五步结果的后面，作为校验（这就是比特币地址的16进制形态）
00010966776006953D5567439E5E39F86A0D273BEED61967F6
第九步，用base58表示法变换一下地址（这就是最常见的比特币地址形态）
