Related question: What opcodes are supported on Liquid but not yet on Bitcoin?
I had seen few opcodes in the slides shared by notgrubles on Twitter
Opcodes:
OP_INSPECTCURRENTINPUT
OP_INSPECTINPUT
OP_INSPECTOUTPUT
OP_TAPTWEAK
OP_MUL64
OP_DIV64
OP_SCALARADD
OP_SCALARMUL
Couldn't find any of these in Bitcoin Core: https://github.com/bitcoin/bitcoin/blob/90f6a623b394e65a34a1918ec67420c899c52bf4/src/script/script.h#L64
So I am assuming they will only be used by Liquid.
Question: What does each of these opcodes do and are OP_MUL64 OP_DIV64 same as OP_MUL OP_DIV?
