This method contrasts with a more restrictive option that involves a rolling "past time limit," which would apply a rule consistently to every block in the blockchain. The preferred approach is to apply rules only to those blocks that are crucial, rather than imposing limitations on every single block. This choice is defended as being more elegant and less invasive, offering a targeted solution without broadly affecting the entire blockchain. The reasoning behind favoring this method includes its simplicity and the belief that it imposes fewer restrictions, thereby maintaining a balance between security and operational flexibility. Furthermore, the discussion is part of a broader conversation on blockchain security and efficiency, as exemplified by the referenced discussion on timestamp attacks.
