Is it actually stunning, provided that cats have primarily dominated the web for the final twenty years, that cat memes have lastly taken over the Bitcoin area as nicely in the previous couple of weeks? Cats are probably the most viral meme on the web, so it is not stunning in in the slightest degree that the Taproot Wizards have leaned into it, strengthened by the trolling Luke over his “dietary selections.”
The query must be requested although, are meme campaigns actually how we wish to go about deciding and discussing consensus adjustments to a protocol as precious as Bitcoin? I’ve seen quite a few music movies, campaigns to exit on this planet and “educate” individuals 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 individuals, if not the one particular person, truly 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 quantity of Bitcoin be despatched to a particular handle, and by consensus there isn’t any different solution to spend these cash besides with a transaction that meets these actual circumstances. 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 primary template covenants (issues requiring a spending transaction to meet sure circumstances outlined forward of time to be legitimate) like this? We all know precisely methods to deal with schemes implementing 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 at the very least 4 covenant proposals that may deal with these use circumstances with a tiny fraction of the information price? “Oh, we wish to experiment with CAT as a result of it’s versatile!” You wish to use 30 OP calls to do one thing that may be achieved in a single? That may be a cause to truly enact a consensus change to Bitcoin? The logic of that’s past absurd.
Downplaying Dangers
In a vacuum OP_CAT is offered as “merely concatenating two strings”, and lots 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 elements of script.
Particularly CSFS + CAT opens a large quantity of potentialities by way of what may be achieved with Bitcoin script, not all of it essentially optimistic. CSFS means that you can confirm a signature on an arbitrary piece of knowledge in the midst of executing a script, and CAT means that you can “glue” completely different items of knowledge collectively on the stack. These two issues create a large design area for what it’s attainable to do with Bitcoin.
One concrete instance could be the potential to implement quantities, or relationships between completely different quantities, of particular inputs and outputs in a transaction. CAT means that you can construct up a transaction hash from particular person items on the stack, and CSFS means that you can confirm a signature towards a public key within the locking script towards arbitrary items of that transaction as it’s constructed up. This might finally allow the creation of open-ended UTXOs anybody can spend, so long as the spending transaction meets sure standards, akin to a certain quantity of cash be despatched to a particular handle. Mix this with the fact of OP_RETURN based mostly property, and this begins entering into the territory of Decentralized Exchanges (DEX).
A number of the worst incentive distortion issues which have come to fruition on different blockchains finally 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, fairly than having to truly carry the danger 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 realized in shitcoin land are coming dwelling to Bitcoin, now whereas I firmly reject the notion that something helpful has been developed on different cash within the final decade apart from the essential idea of zero information proofs, this mantra getting louder ignores a large element of that dynamic even when you disagree with my view there: there are classes to be realized concerning what NOT to do in addition to what TO do.
DEXes are one of many issues NOT to do. Nothing has prompted as a lot chaos, volatility in payment dynamics (which we have to easy 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 that we must always rush to deliver a lot of these issues to Bitcoin, or exacerbate them by introducing a solution to trustlessly embed the bitcoin asset into them in additional dynamic and versatile methods, is frankly insane. This to me speaks of huge swaths of people that haven’t realized something from watching what occurred on different blockchains within the final half decade or so.
Eternally Shackled By The Cat
Trying on the dynamic above between CSFS + CAT, it’s value declaring that Reardencode’s current LNHANCE proposal (CTV + CSFS + Inner Key) presents a path to provide us eltoo for Lightning in a method that’s truly 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 with the intention to simplify Lightning channel administration and implementation upkeep, we very nicely might wind up getting CSFS within the course of. If OP_CAT had been lively previous to this, then there isn’t any solution to keep away from the varieties of detrimental unwanted effects of the 2 proposals being mixed.
This might maintain true for each comfortable fork proposal going ahead if OP_CAT had been ever activated. It might be not possible to flee no matter unwanted effects or use circumstances had been enabled by combining OP_CAT with no matter new proposals are available in future. By itself OP_CAT is clunky, inefficient, and fairly pointless. However together with different OPs it begins to get stupidly versatile and highly effective. This might be a dynamic we might by no means have the ability to escape, and options which may wind up being critically obligatory sooner or later for Bitcoin’s scalability might inescapably include large downsides and dangers merely due to the existence of OP_CAT.
Is that this a actuality we wish to enter merely due to a meme marketing campaign? As a result of individuals wish to tinker with wildly inefficient technique of doing issues as an alternative of wanting by means of rather more environment friendly and function constructed proposals? I’d say no.
Meme campaigns may be enjoyable, I do know this. They foster a way of neighborhood 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, and so they may even be viciously savage at stabbing on to the guts of issues individuals dance round or equivocate on. However they’re atrocious at capturing nuance and complexity in lots of regards.
Making an attempt to steer the consensus of a community like Bitcoin purely based mostly on the worth of a meme, fairly than reasoned consideration of proposals and their implications, is a catastrophe ready to occur. The conservatism and warning of Bitcoin improvement is what has stored it on the forefront of this area as shitcoins have come and gone, imploding within the penalties of their fly by night time carefree improvement perspective. 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 just isn’t how to do this. It dangers destroying what made Bitcoin precious within the first place, its strong and conservative basis.
