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?
In tapscript when the interpreter encounters one of the OP_SUCCESSx opcodes, it instantly succeeds. In the future this might change, and some opcodes might enforce restrictions - soft fork. But the future is not here yet, so nobody knows what and how exactly would happen. So there was OP_CAT at the very beginning, then it was disabled, and now inside tapscript there's OP_SUCCESS126 instead, which might change (in future tapscript version) to something else (instead of instant success).

Where can I see this op_success126? can you give me what opcodes have been replaced by op_success? I didn't find too much useful information, can you tell me?
