The suggestion emphasizes the potential benefits of back-porting tapscript rather than continuing to develop a separate set of opcodes that could further diverge from existing standards.

A notable aspect of this proposal is the introduction of a single upgradeable NOP (No Operation Code) specifically designated as OP_TAPSCRIPTVERIFY. This approach aims to streamline the execution of scripts by allowing for an isolated environment that operates with a distinct set of parameters. Specifically, it would operate on the entire stack except for the top two elements and would only execute if the last opcode performed by the script interpreter is a push opcode. Failure of the internal script results in the operation failing, whereas successful execution leads to no action, maintaining the integrity and state of the stack.

Additionally, the concept of a faux control block is introduced as part of the execution framework for tapscript. This control block would not require extensive data, being just a few bytes primarily for indicating the tapscript version, thus simplifying the implementation process while ensuring backward compatibility and future-proofing through its upgradeable nature.

This discussion reflects the ongoing efforts within the Bitcoin development community to enhance script functionality and efficiency, illustrating the collaborative approach to evolving the protocol's capabilities while considering the implications of interoperability and system complexity.
