I read the code, but I didn’t understand what is the purpose of this upgrade of OP_SUCCESS? Can you give me a detailed explanation? Thank you
This makes taproot upgradable.
I know, but can you tell me the specific meaning of tapscript (Many previously disabled opcodes are redefined to be OP_SUCCESS opcodes that unconditionally render the entire script valid to simplify soft fork upgrades.)? I don’t understand what OP_SUCCESS specifically redefines? How is it used?
