系统由三个核心模块组成：
脚本解析器：将 Script 操作码转换为可执行指令。
栈与执行引擎：模拟比特币脚本的执行环境，包含主栈与 alt 栈。
余额模拟器：管理 UTXO 集合，根据脚本执行结果更新余额。
核心代码实现
- 操作码定义与指令映射
pythonopcodes.py
OPCODES = {
'OP_DUP': 0x76,
'OP_HASH160': 0xa9,
'OP_EQUALVERIFY': 0x88,
'OP_CHECKSIG': 0xac,
'OP_ADD': 0x93,
'OP_SUB': 0x94,
'OP_VERIFY': 0x69,可根据需要扩展更多操作码
}
class Instruction:
def init(self, opcode, data=None):
self.opcode = opcode
self.data = data
栈与执行引擎
pythonengine.py
class Stack:
def init(self):self.items = []def push(self, item):
self.items.append(item)def pop(self):
if not self.items: raise IndexError("Stack underflow") return self.items.pop()def top(self):
return self.items[-1] if self.items else None
class ScriptEngine:
def init(self):
self.main_stack = Stack()
self.alt_stack = Stack()
self.scripts = []
self.pc = 0 # program counter
def load_script(self, script_bytes):
# 简化：将字节码转换为指令列表
self.scripts = self._parse(script_bytes)
self.pc = 0
def _parse(self, script_bytes):
# 实际解析逻辑（略）
return [Instruction(OPCODES['OP_DUP']), Instruction(OPCODES['OP_HASH160'])]
def step(self):
if self.pc >= len(self.scripts):
return False
ins = self.scripts[self.pc]
self._execute(ins)
self.pc += 1
return True
def _execute(self, ins):
op = ins.opcode
if op == OPCODES['OP_DUP']:
val = self.main_stack.pop()
self.main_stack.push(val)
self.main_stack.push(val)
elif op == OPCODES['OP_ADD']:
a = self.main_stack.pop()
b = self.main_stack.pop()
self.main_stack.push(a + b)
# ... 其他操作码实现
- 余额模拟器（UTXO 模型）
pythonbalance_simulator.py
from engine import ScriptEngine
class UTXO:
def init(self, txid, vout, amount, script_pubkey):
self.txid = txid
self.vout = vout
self.amount = amount
self.script_pubkey = script_pubkey
class BalanceSimulator:
def init(self):
self.utxos = [] # UTXO set
self.history = [] # transaction history
def add_utxo(self, utxo):
self.utxos.append(utxo)
def spend(self, utxo, unlocking_script, amount_to_spend):
if utxo.amount < amount_to_spend:
raise ValueError("Insufficient funds")
# 验证脚本
engine = ScriptEngine()
# 构造完整的 Script：unlocking_script + locking_script
full_script = unlocking_script + utxo.script_pubkey
engine.load_script(full_script)
try:
while engine.step():
pass
if engine.main_stack.pop() != 1: # 成功标志应为 true
raise Exception("Script execution failed")
except Exception as e:
raise Exception(f"Invalid script: {e}")
# 更新 UTXO
self.utxos.remove(utxo)
# 找零
if utxo.amount > amount_to_spend:
change_utxo = UTXO(
txid="change_tx",
vout=len(self.history),
amount=utxo.amount - amount_to_spend,
script_pubkey=utxo.script_pubkey
)
self.utxos.append(change_utxo)
self.history.append({
'spent': utxo,
'amount': amount_to_spend,
'change': utxo.amount - amount_to_spend
})
return amount_to_spend # 成功花费
def get_balance(self):
return sum(utxo.amount for utxo in self.utxos)
- 训练系统前端（交互式 CLI）
pythontrainer.py
from balance_simulator import BalanceSimulator, UTXO
def main():
sim = BalanceSimulator()
# 初始化一个 UTXO，金额 10 BTC，锁定脚本为 OP_DUP OP_HASH160 <pubkey_hash> OP_EQUALVERIFY OP_CHECKSIG
sim.add_utxo(UTXO("genesis", 0, 10, b'\x76\xa9\x14' + b'\x00'*20 + b'\x88\xac'))
print("Bitcoin Script Training System - Balance Simulator")
print("Current balance:", sim.get_balance(), "BTC")
print("Available UTXOs:")
for i, utxo in enumerate(sim.utxos):
print(f" [{i}] {utxo.amount} BTC - script: {utxo.script_pubkey.hex()}")
# 模拟用户输入解锁脚本
user_script = input("Enter unlocking script (hex): ")
try:
unlocking_bytes = bytes.fromhex(user_script)
sim.spend(sim.utxos[0], unlocking_bytes, 5.0)
print("Transaction succeeded! New balance:", sim.get_balance(), "BTC")
except Exception as e:
print("Transaction failed:", e)
if name == "main":
main()
系统演示与训练目标
用户可以通过以下方式训练：
编写解锁脚本：例如为 P2PKH 提供签名与公钥。
观察栈状态：可在执行引擎中添加栈快照功能，逐步调试。
余额变化验证：确保脚本逻辑符合预期支出。
