有了这个安全防护，即使有人真的掌握了全网 50% 以上的 CPU 算力，也无法试图回退、重做昨天之前的区块链。（前提是你装了这个更新）
The security safeguard makes it so even if someone does have more than 50% of the network's CPU power, they can't try to go back and redo the block chain before yesterday. (if you have this update)
从现在起我大概会在每个版本里放一个检查点。一旦软件已经确认了被广泛接受的区块链是什么样，就没有必要留下「几个月后翻案」这种人们不需要的非零可能性。
I'll probably put a checkpoint in each version from now on. Once the software has settled what the widely accepted block chain is, there's no point in leaving open the unwanted non-zero possibility of revision months later.
