![好的！下面是一个简单的区块链钱包的示例代码，使用Python语言编写。这个代码展示了如何创建一个基本的区块链钱包。请注意，这只是一个基础示例，实际应用中还需考虑许多安全性和功能性问题。
### 区块链钱包示例代码
```python

import json
from time import time
from flask import Flask, jsonify, request
class Blockchain:
def __init__(self):
self.chain = []
self.current_transactions = []
self.new_block(previous_hash='1', miner='Genesis')
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]
app = Flask(__name__)
node_address = str(uuid4()).replace('-', '')
blockchain = Blockchain()
@app.route('/mine', methods=['GET'])

last_block = blockchain.last_block
last_proof = last_block['proof']
proof = blockchain.proof_of_work(last_proof)
blockchain.new_transaction(
