以下是一个简单的数字货币钱包开发源码demo，使用Python语言和PyCrypto库实现：
import hashlib
import json
import os
数字货币地址
ADDRESS = "0x12345678"
钱包文件路径
FILE_PATH = "./wallet.json"
私钥保存路径
PRIVATE_KEY_PATH = "./private.key"
保存钱包文件
def save_wallet():
with open(FILE_PATH, "w") as f:
f.write(json.dumps(get_wallet_info(), sort_keys=True, indent=4))
从钱包文件读取私钥
def load_private_key():
with open(PRIVATE_KEY_PATH, "r") as f:
private_key = f.read()
return json.loads(private_key)
获取钱包信息
def get_wallet_info():
info = {
"addresses": [ADDRESS],
"keys": []
}
for filename in [FILE_PATH, "./private.key"]:
if os.path.exists(filename):
with open(filename, "r") as f:
info = json.load(f)
return info
生成随机地址
def generate_address():
return "".join(format(int(hashlib.new("hex", str(ADDRESS)).hexdigest()), "02"))
验证地址
def verify_address(address):
info = get_wallet_info()
if address in info["addresses"]:
return True
for filename in [FILE_PATH, "./private.key"]:
if os.path.exists(filename):
with open(filename, "r") as f:
info = json.load(f)
retu 存储数字货币地址和私钥
- 从钱包文件读取私钥
- 验证地址
- 存储地址和私钥
- 加载地址和私钥
请注意，此demo仅用于演示数字货币钱包开发的基本原理，实际应用中需要考虑
