Bug: CanPersistBlock Always False On Small Network #832
Description
Description
Current check on block persistance only limit to 2 persist round,
- previous round
- current round
on small network (less than 5) with some configuration on smithing period and smithing gap, the time overlap causes the valid blocksmith time always skipped.
say blocksmith_a can persist at prev(100 - 110), current(120 - 130), next(140 - 150)
if we cover 2 round, by the time we reach 100++, our previous become (120 - 130) and current become (140 - 150)
That's why need to add previous2n into the comparison scope to handle small network.
