The block timestamp may not be greater than 2^32 (Sun, 07 Feb 2106 > 06:28:16 +0000) What happens if a series of blocks has a timestamp of 0xFFFFFFFF at the appropriate time? In that case: 1. Is not violated, since "not lower than" means "greater than or equal to", and after a while the median becomes 0xFFFFFFFF and 0xFFFFFFFF == 0xFFFFFFFF 2. Is not violated, since it would be a past actual real time. 3. Is not violated since 0xFFFFFFFF < 0x100000000. In that case, we could then add an additional rule, which is that a 64-bit (or 128-bit, or 256-bit) timestamp has to be present in the coinbase transaction, with similar rules except translated to 64-bit/128-bit/256-bit. Possibly a similar scheme could be used for `nLockTime`; we could put a 64-bit `nLockTime64` in that additional signed block in Taproot SegWit v1 if the legacy v`nLockTime` is at the maximum seconds-timelock possible.
