The maximum size of blocks in between doublings will increase linearly based on the block's timestamp. The maximum size of blocks after 2036-01-06 00:00:00 UTC shall be 8,192,000,000 bytes. >   > Since it's possible that block timestamps aren't chronological in order, what would happen if a block following a size increase trigger is back in the past before the size increase? Would that block have a lower size restriction again? Would using block height not be a more stable number to work with? In the nVersion bits proposal that I co-authored we solved that issue by comparing the timestamp against the median time, which is guaranteed by the protocol rules to monotonically advance. -- 'peter'[:-1]@petertodd.org 0000000000000000138b2613c026e0ed1dbf6f8f193f1c3115bdf540dc22fbf6
