创建一个完整的区块链钱包源码涉及到复杂的编程和安全性考虑。在这里，我可以提供一个简单的概念和示例代码，以帮助你理解构建区块链钱包的基本结构。这段代码将以Python语言为基础，利用了相关的库来实现一个简单的钱包概念。 ### 简单的区块链钱包示例 ```python import hashlib import json from time import time from urllib.parse import urlparse import requests class Blockchain: def __init__(self): self.chain = [] self.current_transactions = [] self.nodes = set() self.new_block(previous_hash='1', proof=100) def new_block(self, proof, previous_hash=None): block = { 'index': len(self.chain) 1, 'timestamp': time(), 'transactions': self.current_transactions, 'proof': proof, 'previous_hash': previous_hash or self.hash(self.chain[-1]), } self.current_transactions = [] self.chain.append(block) return block def new_transaction(self, sender, recipient, amount): self.current_transactions.append({ 'sender': sender, 'recipient': recipient, 'amount': amount, }) return self.last_block['index'] 1 @staticmethod def hash(block): block_string = json.dumps(block, sort_keys=True).encode() return hashlib.sha256(block_string).hexdigest() @property def last_block(self): return self.chain[-1] def register_node(self, address): parsed_url = urlparse(address) self.nodes.add(parsed_url.netloc) def valid_chain(self, chain): last_block = chain[0] current_index = 1 while current_index len(chain): block = chain[current_index] if block['previous_hash'] != self.hash(last_block): return False last_block = block current_index = 1 return True # 创建区块链实例并添加交易 blockchain = Blockchain() blockchain.new_transaction(sender=创建一个完整的区块链钱包源码涉及到复杂的编程和安全性考虑。在这里，我可以提供一个简单的概念和示例代码，以帮助你理解构建区块链钱包的基本结构。这段代码将以Python语言为基础，利用了相关的库来实现一个简单的钱包概念。 ### 简单的区块链钱包示例 ```python import hashlib import json from time import time from urllib.parse import urlparse import requests class Blockchain: def __init__(self): self.chain = [] self.current_transactions = [] self.nodes = set() self.new_block(previous_hash='1', proof=100) def new_block(self, proof, previous_hash=None): block = { 'index': len(self.chain) 1, 'timestamp': time(), 'transactions': self.current_transactions, 'proof': proof, 'previous_hash': previous_hash or self.hash(self.chain[-1]), } self.current_transactions = [] self.chain.append(block) return block def new_transaction(self, sender, recipient, amount): self.current_transactions.append({ 'sender': sender, 'recipient': recipient, 'amount': amount, }) return self.last_block['index'] 1 @staticmethod def hash(block): block_string = json.dumps(block, sort_keys=True).encode() return hashlib.sha256(block_string).hexdigest() @property def last_block(self): return self.chain[-1] def register_node(self, address): parsed_url = urlparse(address) self.nodes.add(parsed_url.netloc) def valid_chain(self, chain): last_block = chain[0] current_index = 1 while current_index len(chain): block = chain[current_index] if block['previous_hash'] != self.hash(last_block): return False last_block = block current_index = 1 return True # 创建区块链实例并添加交易 blockchain = Blockchain() blockchain.new_transaction(sender=
