For that matter, since an entire microcode represents a language (based on = the current OG Bitcoin SCRIPT language), with a little more coordination, w= e could entirely replace Tapscript versions --- every Tapscript version is = a slot for a microcode, and the current OG Bitcoin SCRIPT is just the one i= n slot `0xc2`. Filled slots cannot be changed, but new microcodes can use some currently-e= mpty Tapscript version slot, and have it properly defined in a microcode in= troduction outpoint. Then indication of a microcode would take only one byte, that is already ne= eded currently anyway. That does limit us to only 255 new microcodes, thus the cost of one microco= de would have to be a good bit higher. Again, remember, microcodes represent an entire language that is an extensi= on of OG Bitcoin SCRIPT, not individual operations in that language. Regards, ZmnSCPxj
