One could design a SC with a sidecoin plus a faster tx time for scBTC, I think.
Which goes back to the question i had for you yesterday, is this possible?
Possible I guess, but let me spin the question around. Is this desirable?
Remember that in that scenario the sidecoin does NOT have the same value as the scBTC residing on the same chain. Users & miners have no use for the sidecoin as the scBTC is safer, more risk-averse (it has the "risk-free" put as you put it)
