is there any good discussion about why blockchain has no minimum time interval ?
1-minute block intervals should be precluded by design but guessing there is justification ?
What you are referring to would be a new consensus rule then. Interesting idea, but I'd think at least 5 min before another block would be better. Could be unintended consequences.
Truth: This is exquisitely difficult to believe that there is no visible discussion about this. There must have been some discusion about this somewhere, somewhen, by someone.
