还有一点我不太明白——全局链是不是只有在确实有事要做时才会延长？目前它似乎一直在增长，尽管网络里只有几个人。所以，我猜它是在添加空区块。这真的有必要吗？时间戳不一定非要与现实时间同步，对吧……它只是用来确定事件的先后顺序。
Something else that isn't clear to me - does the global chain only get extended when there is actual work to do? Currently it seems to grow all the time, although there are only a few people in the network. So presumably it gets extended with null blocks. Is this actually required? The timestamping doesn't have to be actually in parallel with real time does it ... it's merely establishing an ordering of events.
它一直在不断延长。如果停下来，攻击者就会有时间追上。别担心，空区块并不大。
It keeps getting extended all the time. If it stopped, an attacker would have time to catch up. Don't worry, empty blocks aren't very big.
正如你说的，重要的是事件的顺序。
As you say, it's the order of events that matters.
