Thanks Antoine and Pieter
I am just trying to wrap my head around why the 0.6% cannot compound.
If miners conduct the timewarp attack, then in epoch 2 they manipulate the difficulty down 0.6%
Then in epoch 3, since the difficulty is lower (But the hashrate is the same), the miners are expected to produce 0.6% more blocks. Then they use the fake timestamp trick again, shifting the difficulty down 0.6%, but that only offsets the impact of the 0.6% more blocks. So with this 2 hour rule, miners can only achieve a one-off 0.6% downward shift?
Am I thinking about that correctly?
Miners could of course just produce fewer blocks and keep shifting the difficulty downwards, but then that isnt really an attack with fake timestamps, that is just mining less
