在区块链开发中，钱包是一个至关重要的组成部分。它涉及到账户管理、密钥生成、交易处理等功能。以下是一个简单的区块链钱包的Python代码示例，展示了如何创建、管理和使用区块链钱包的基本功能。 ### 区块链钱包代码示例 ```python import hashlib import random import json from time import time class Wallet: def __init__(self): self.private_key = self.generate_private_key() self.public_key = self.generate_public_key(self.private_key) self.balance = 0 def generate_private_key(self): # 随机生成一个密钥 return str(random.randint(0, 1000000)) def generate_public_key(self, private_key): # 使用哈希函数生成公钥（示例中简化处理） return hashlib.sha256(private_key.encode()).hexdigest() def get_balance(self): return self.balance def send_transaction(self, amount, recipient): if self.balance = amount: self.balance -= amount return True else: return False class Transaction: def __init__(self, sender, recipient, amount): self.sender = sender self.recipient = recipient self.amount = amount self.timestamp = time() def to_dict(self): return { 'sender': self.sender, 'recipient': self.recipient, 'amount': self.amount, 'timestamp': self.timestamp } class Blockchain: def __init__(self): self.chain = [] self.current_transactions = [] def add_block(self, block): self.chain.append(block) def create_transaction(self, sender, recipient, amount): transaction = Transaction(sender, recipient, amount) self.current_transactions.append(transaction.to_dict()) return transaction def mine_block(self): # 模拟区块的挖掘过程，仅为示例 block = { 'index': len(self.chain) 1, 'transactions': self.current_transactions, 'timestamp': time() } self.current_transactions = [] # 重置当前交易 self.add_block(block) def main(): # 创建钱包 my_wallet = Wallet() # 初始化区块链 my_blockchain = Blockchain() # 为钱包添加一些初始余额 my_wallet.balance = 100 # 给钱包初始资金 # 创建一笔交易 transaction1 = my_blockchain.create_transaction(my_wallet.public_key, 'recipient_public_key', 50) # 发送交易 if my_wallet.send_transaction(50, 'recipient_public_key'): print(在区块链开发中，钱包是一个至关重要的组成部分。它涉及到账户管理、密钥生成、交易处理等功能。以下是一个简单的区块链钱包的Python代码示例，展示了如何创建、管理和使用区块链钱包的基本功能。 ### 区块链钱包代码示例 ```python import hashlib import random import json from time import time class Wallet: def __init__(self): self.private_key = self.generate_private_key() self.public_key = self.generate_public_key(self.private_key) self.balance = 0 def generate_private_key(self): # 随机生成一个密钥 return str(random.randint(0, 1000000)) def generate_public_key(self, private_key): # 使用哈希函数生成公钥（示例中简化处理） return hashlib.sha256(private_key.encode()).hexdigest() def get_balance(self): return self.balance def send_transaction(self, amount, recipient): if self.balance = amount: self.balance -= amount return True else: return False class Transaction: def __init__(self, sender, recipient, amount): self.sender = sender self.recipient = recipient self.amount = amount self.timestamp = time() def to_dict(self): return { 'sender': self.sender, 'recipient': self.recipient, 'amount': self.amount, 'timestamp': self.timestamp } class Blockchain: def __init__(self): self.chain = [] self.current_transactions = [] def add_block(self, block): self.chain.append(block) def create_transaction(self, sender, recipient, amount): transaction = Transaction(sender, recipient, amount) self.current_transactions.append(transaction.to_dict()) return transaction def mine_block(self): # 模拟区块的挖掘过程，仅为示例 block = { 'index': len(self.chain) 1, 'transactions': self.current_transactions, 'timestamp': time() } self.current_transactions = [] # 重置当前交易 self.add_block(block) def main(): # 创建钱包 my_wallet = Wallet() # 初始化区块链 my_blockchain = Blockchain() # 为钱包添加一些初始余额 my_wallet.balance = 100 # 给钱包初始资金 # 创建一笔交易 transaction1 = my_blockchain.create_transaction(my_wallet.public_key, 'recipient_public_key', 50) # 发送交易 if my_wallet.send_transaction(50, 'recipient_public_key'): print(
