其他参与者原话llama原帖 ↗但是，如果发生的是签名被攻破（也许整数分解被解决了？量子计算机？），那么就算对最后一个有效区块达成共识也毫无意义。
However, if something happened and the signatures were compromised (perhaps integer factorization is solved, quantum computers?), then even agreeing upon the last valid block would be worthless.
没错，如果它是突然发生的。如果它是渐进的，我们仍能过渡到更强的方案。你第一次运行升级后的软件时，它会用新的更强签名算法给你所有的钱重新签名。（方式是创建一笔把钱发送给你自己的更强签名的交易）
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)
