Is it actually shocking, provided that cats have basically dominated the web for the final 20 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 least that the Taproot Wizards have leaned into it, bolstered by the trolling Luke over his “dietary choices.”
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 priceless 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 happening…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 individual, really tinkering and taking part in with OP_CAT to construct out use case examples, has made a demo of a OP_CAT primarily based covenant script.
This script enforces a certain amount of Bitcoin be despatched to a selected deal with, and by consensus there isn’t a different technique to spend these cash besides with a transaction that meets these precise situations. Have a look at the scale 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 satisfy sure situations outlined forward of time to be legitimate) like this? We all know precisely tips on how 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 satisfy the wants of a category of use circumstances which are mature sufficient in design that there are at the least 4 covenant proposals that may deal with these use circumstances with a tiny fraction of the info value? “Oh, we want to experiment with CAT because it’s flexible!” You need to use 30 OP calls to do one thing that may be accomplished in a single? That may be a motive to truly enact a consensus change to Bitcoin? The logic of that’s past absurd.
Downplaying Dangers
In a vacuum OP_CAT is bought as “simply concatenating two strings”, and lots of the memes try framing it as “how can that be dangerous?” This can be a wildly disingenuous narrative surrounding the proposal, and it fully ignores the way it interacts with different present and future points of script.
Particularly CSFS + CAT opens a large quantity of potentialities when it comes to what might be accomplished with Bitcoin script, not all of it essentially constructive. CSFS lets you confirm a signature on an arbitrary piece of knowledge in the middle of executing a script, and CAT lets you “glue” totally different items of knowledge collectively on the stack. These two issues create a huge design area for what it’s potential to do with Bitcoin.
One concrete instance could be the potential to implement quantities, or relationships between totally different quantities, of particular inputs and outputs in a transaction. CAT lets you construct up a transaction hash from particular person items on the stack, and CSFS lets you confirm a signature towards a public key within the locking script towards 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, reminiscent of a certain amount of cash be despatched to a selected deal with. Mix this with the truth of OP_RETURN primarily based property, and this begins stepping into the territory of Decentralized Exchanges (DEX).
A few 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 trade performance on the blockchain is without doubt one of 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, quite than having to truly 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 back.” I.e. that classes discovered in shitcoin land are coming house 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 a large element of that dynamic even in case you disagree with my view there: there are classes to be discovered relating to what NOT to do in addition to what TO do.
DEXes are one of many issues NOT to do. Nothing has brought on as a lot chaos, volatility in charge dynamics (which we have to easy out over time for sustainability of second layers), and simply throughout incentive chaos relating to the bottom consensus layers of those protocols and their diploma of centralization. The concept that we should always rush to carry these kind of issues to Bitcoin, or exacerbate them by introducing a technique 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.
Perpetually Shackled By The Cat
Trying on the dynamic above between CSFS + CAT, it’s value stating that Reardencode’s current LNHANCE proposal (CTV + CSFS + Inner Key) provides a path to provide us eltoo for Lightning in a method that’s really more blockspace efficient than utilizing APO. If this argumentation, and construct out of proof of ideas, winds up profitable over Lightning builders who need LN symmetry as a way to simplify Lightning channel administration and implementation upkeep, we very nicely may wind up getting CSFS within the course of. If OP_CAT have been energetic previous to this, then there isn’t a technique to keep away from the kinds of detrimental uncomfortable side effects of the 2 proposals being mixed.
This is able to maintain true for each mushy fork proposal going ahead if OP_CAT have been ever activated. It could be unattainable to flee no matter uncomfortable side effects or use circumstances have been enabled by combining OP_CAT with no matter new proposals are available future. By itself OP_CAT is clunky, inefficient, and quite pointless. However together with different OPs it begins to get stupidly versatile and highly effective. This is able to be a dynamic we’d by no means be capable to escape, and options that may wind up being critically vital sooner or later for Bitcoin’s scalability may inescapably include huge 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 individuals need to tinker with wildly inefficient technique of doing issues as an alternative of wanting by way of far more environment friendly and function constructed proposals? I’d say no.
Meme campaigns might 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 ought to be deciding the event technique of Bitcoin. They are often enjoyable, they usually may even be viciously savage at stabbing on to the center of issues individuals 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 primarily based on the worth of a meme, quite 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 evening 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 shouldn’t be how to try this. It dangers destroying what made Bitcoin priceless within the first place, its strong and conservative basis.
