Rationale: we should use time-to-verify as the metric, because everything revolves around the 10-minutes-per-block constant.
...let's lower that constant. ...
In summary, I propose that to avoid the tragedy of the commons problem, instead of limiting the available space, we limit the available time allowed for the block to propagate instead. Now THAT is a Bitcoin 2.0 (or rather, 1.0)
For the rest of us who are catching up, are you proposing what seems far more radical than eliminating the 1Mb limit? Can you please clarify. Are you proposing reducing the 10 min average block creation time? If so, what happens to the 25 BTC reward which would be excessive, and need a pro-rata reduction for increased block frequency?
