Good morning again Russell,

ing 32-byte encoding of opcodes, is still rather long winded?
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.

ZmnSCPxj
