nostr:npub1a2cww4kn9wqte4ry70vyfwqyqvpswksna27rtxd8vty6c74era8sdcw83a asked a great question yesterday: why no temporary softforks?

Here's Base58's niftynei on the difficulty with adding opcodes to bitcoin

one minor correction: the video says you can't tell what opcodes are used in unspent scripts.

this is true. you *can* however tell what version of scripts bitcoin is locked up to.

so theoretically you could remove support for a version of script once all bitcoin locked up to that script version had been spent.

there are currently 3 versions of scripts in bitcoin; none of them have ever been deprecated and all of them currently have funds locked up to them.

the most recently 'removed' opcode is OP_CHECKMULTISIG; it's available in pre-segwit and segwit v0 scripts.

it's not available for segwit v1 scripts (aka taproot scripts or tapscript)

Ah, but this would mean that you are relying on people moving coins to a new address type?

If that's the case, it's pretty clear why it's unfeasible, it took forever for people to adopt segwit, and it's taking forever more for people to start using taproot.
