Zawy’s Alternating Timestamp Attack

[murch]

@sjors

With FTL meaning “Future Time Limit”. So do you mean just the existing rule that when we see a block it can’t be more than 2 hours in the future? Or do you mean the timestamp can’t be more than 2 hours ahead of that in the previous block?

The latter: we would not accept a block with a timestamp more than two hours in the future. (We have had “benign” gaps of more than two hours between blocks before.)
