不过，万一签名被攻破了（比如整数分解被解决了、量子计算机？），那连"最后一个有效块"达成共识都没意义了。
对，如果是突然发生的，确实没意义。如果是慢慢发生的，我们还能过渡到更强的算法。你第一次运行升级后的软件时，它会用新的更强的签名算法重新签署你所有的钱（做法是建一笔把钱转给自己的交易，用强签名）。

True, if it happened suddenly. If it happens gradually, we can still transition to something stronger. When you run the upgraded software for the first time, it would re-sign all your money with the new stronger signature algorithm. (by creating a transaction sending the money to yourself with the stronger sig)
