Is it actually shocking, on condition that cats have primarily dominated the web for the final twenty years, that cat memes have lastly taken over the Bitcoin house as nicely in the previous couple of weeks? Cats are probably the most viral meme on the web, so it is not surprising in in the slightest degree that the Taproot Wizards have leaned into it, bolstered by the trolling Luke over his “dietary selections.”
The query must be requested although, are meme campaigns actually how we need to go about deciding and discussing consensus adjustments to a protocol as invaluable as Bitcoin? I’ve seen quite a few music movies, campaigns to exit on this planet and “educate” folks on OP_CAT, and the entire “Quest” system that Taproot Wizards has launched going down…however the actuality is the overwhelming majority of this content material that I’ve seen has been extremely superficial.
Rijndael, “Artificer” at Taproot Wizards and one of many few folks, if not the one individual, really tinkering and enjoying with OP_CAT to construct out use case examples, has made a demo of a OP_CAT based mostly covenant script.
This script enforces a certain amount of Bitcoin be despatched to a selected handle, and by consensus there is no such thing as a different strategy to spend these cash besides with a transaction that meets these precise situations. Take a look at the dimensions of this script:

That is what it takes to emulate CHECKTEMPLATEVERIFY. The equal script utilizing CTV would merely be:
CTV .
I ask, what’s the worth of one thing like OP_CAT in emulating the case of fundamental template covenants (issues requiring a spending transaction to meet sure situations outlined forward of time to be legitimate) like this? We all know precisely easy methods to deal with schemes imposing a template on transactions spending an output locked to a template covenant, and have a number of proposals for them. CTV, TXHASH, OP_TX, and even APO can emulate these schemes by stuffing a signature within the locking output of a transaction at the price of an additional 64 bytes.
What precise use is OP_CAT in “experimenting” to fulfill the wants of a category of use circumstances which are mature sufficient in design that there are not less than 4 covenant proposals that may deal with these use circumstances with a tiny fraction of the information price? “Oh, we need to experiment with CAT as a result of it’s versatile!” You need to use 30 OP calls to do one thing that may be finished in a single? That could be a motive to really enact a consensus change to Bitcoin? The logic of that’s past absurd.
Downplaying Dangers
In a vacuum OP_CAT is bought as “merely concatenating two strings”, and most of the memes try framing it as “how can that be harmful?” This can be a wildly disingenuous narrative surrounding the proposal, and it utterly ignores the way it interacts with different current and future features of script.
Specifically CSFS + CAT opens an enormous quantity of potentialities when it comes to what will be finished with Bitcoin script, not all of it essentially optimistic. CSFS permits you to confirm a signature on an arbitrary piece of information in the middle of executing a script, and CAT permits you to “glue” completely different items of information collectively on the stack. These two issues create an enormous design house for what it’s potential to do with Bitcoin.
One concrete instance can be the potential to implement quantities, or relationships between completely different quantities, of particular inputs and outputs in a transaction. CAT permits you to construct up a transaction hash from particular person items on the stack, and CSFS permits you to confirm a signature in opposition to a public key within the locking script in opposition to arbitrary items of that transaction as it’s constructed up. This might in the end allow the creation of open-ended UTXOs anybody can spend, so long as the spending transaction meets sure standards, corresponding to a certain amount of cash be despatched to a selected handle. Mix this with the fact of OP_RETURN based mostly belongings, and this begins moving into the territory of Decentralized Exchanges (DEX).
A number of the worst incentive distortion issues which have come to fruition on different blockchains in the end stem from the creation of DEXes on these chains. Having direct non-interactive alternate performance on the blockchain is among the worst types of MEV, particularly when the potential exists for miners to lock-in their revenue throughout a number of trades within the span of a single block, reasonably than having to really carry the chance of a place throughout a number of blocks earlier than closing it out and realizing revenue.
A part of the motion behind Taproot Wizards is “bringing the innovation again.” I.e. that classes discovered in shitcoin land are coming residence to Bitcoin, now whereas I firmly reject the notion that something helpful has been developed on different cash within the final decade aside from the fundamental idea of zero data proofs, this mantra getting louder ignores an enormous part of that dynamic even when you disagree with my view there: there are classes to be discovered concerning what NOT to do in addition to what TO do.
DEXes are one of many issues NOT to do. Nothing has triggered as a lot chaos, volatility in price dynamics (which we have to clean out over time for sustainability of second layers), and simply throughout incentive chaos concerning the bottom consensus layers of those protocols and their diploma of centralization. The concept we should always rush to convey these kind of issues to Bitcoin, or exacerbate them by introducing a strategy to trustlessly embed the bitcoin asset into them in additional dynamic and versatile methods, is frankly insane. This to me speaks of enormous swaths of people that haven’t discovered something from watching what occurred on different blockchains within the final half decade or so.
Endlessly Shackled By The Cat
Trying on the dynamic above between CSFS + CAT, it’s value mentioning that Reardencode’s latest LNHANCE proposal (CTV + CSFS + Inner Key) affords a path to offer us eltoo for Lightning in a means that’s really extra blockspace environment friendly than utilizing APO. If this argumentation, and construct out of proof of ideas, winds up profitable over Lightning builders who need LN symmetry to be able to simplify Lightning channel administration and implementation upkeep, we very nicely may wind up getting CSFS within the course of. If OP_CAT had been lively previous to this, then there is no such thing as a strategy to keep away from the sorts of detrimental unintended effects of the 2 proposals being mixed.
This is able to maintain true for each tender fork proposal going ahead if OP_CAT had been ever activated. It could be unimaginable to flee no matter unintended effects or use circumstances had been enabled by combining OP_CAT with no matter new proposals are available future. By itself OP_CAT is clunky, inefficient, and reasonably pointless. However together with different OPs it begins to get stupidly versatile and highly effective. This is able to be a dynamic we might by no means have the ability to escape, and options which may wind up being critically vital sooner or later for Bitcoin’s scalability may inescapably include large downsides and dangers merely due to the existence of OP_CAT.
Is that this a actuality we need to enter merely due to a meme marketing campaign? As a result of folks need to tinker with wildly inefficient technique of doing issues as an alternative of trying by means of far more environment friendly and function constructed proposals? I’d say no.
Meme campaigns will be enjoyable, I do know this. They foster a way of group and involvement, it is an inherent and inescapable a part of the web and the quite a few cultures that exist on it. However this isn’t how we must be deciding the event means of Bitcoin. They are often enjoyable, they usually may even be viciously savage at stabbing on to the guts of issues folks dance round or equivocate on. However they’re atrocious at capturing nuance and complexity in lots of regards.
Attempting to steer the consensus of a community like Bitcoin purely based mostly on the worth of a meme, reasonably than reasoned consideration of proposals and their implications, is a catastrophe ready to occur. The conservatism and warning of Bitcoin growth is what has stored it on the forefront of this house as shitcoins have come and gone, imploding within the penalties of their fly by night time carefree growth angle. As a lot as Bitcoin sorely wants to interrupt out of its present rut of stagnation and lack of ahead progress, devolving to uncritical memes and music movies isn’t how to do this. It dangers destroying what made Bitcoin invaluable within the first place, its strong and conservative basis.
