Is it actually stunning, contemplating that cats have primarily dominated the web for the previous 20 years, that cat memes have lastly taken over the Bitcoin house in current weeks? Cats are essentially the most viral meme on the web, so it is in no way stunning that the Taproot Wizards have leaned into it, amplified by trolling Luke about his “weight-reduction plan selections.”
Nonetheless, the query should be requested: are meme campaigns actually how we need to go about deciding and discussing consensus adjustments in a protocol as useful as Bitcoin? I’ve seen numerous music movies, campaigns to exit into the world and ‘educate’ individuals about OP_CAT, and the entire ‘Quest’ system that Taproot Wizards has launched is going on… however the actuality is that the overwhelming majority of This content material I noticed was extremely superficial.
Rijndael, “Artificer” at Taproot Wizards and one of many few individuals, if not the one one, truly tinkering and enjoying with OP_CAT to construct out use circumstances, has created a demo of an OP_CAT primarily based covenant script.
This script forces a certain quantity of Bitcoin to be despatched to a particular tackle, and by consensus there is no such thing as a different approach to spend these cash besides with a transaction that meets these actual circumstances. Have a look at the scale of this script:

That is what it takes to emulate CHECKTEMPLATEVERIFY. The equal script that CTV makes use of would merely be:
CTV.
I am questioning: what’s the worth of one thing like OP_CAT in simulating the case of fundamental template covenants (issues the place a spending transaction should meet sure circumstances outlined prematurely to be legitimate) like this? We all know precisely how you can cope with preparations that implement a template for transactions that file an output tied to a template covenant, and we’ve got a number of proposals for doing so. CTV, TXHASH, OP_TX, and even APO can emulate these schemes by placing a signature within the locking output of a transaction, which prices a further 64 bytes.
What precise use is OP_CAT in “experimenting” to satisfy the wants of a category of use circumstances which are so mature by design that there are at the very least 4 covenant proposals that may deal with these use circumstances with a small fraction of the info price? “Oh, we need to experiment with CAT as a result of it is versatile!” Need to use 30 OP calls to do one thing that may be executed in a single go? Is {that a} purpose to truly make a consensus change in Bitcoin? The logic of that is past absurd.
Downplay dangers
In a vacuum, OP_CAT is offered as “merely concatenating two strings,” and most of the memes attempt to body it as “how can that be harmful?” This can be a massively disingenuous narrative surrounding the proposal, and it fully ignores the way it interacts with different current and future features of the script.
CSFS+CAT particularly opens up an enormous quantity of potentialities when it comes to what could be executed with the Bitcoin script, and never all of that is essentially constructive. CSFS permits you to confirm a signature on any piece of information whereas operating a script, and CAT permits you to “glue” collectively completely different items of information on the stack. These two issues create one monumental design house for what is feasible with Bitcoin.
A concrete instance could be the power to implement quantities, or relationships between completely different quantities, of particular inputs and outputs in a transaction. CAT permits you to construct a transaction hash from particular person chunks on the stack, and CSFS permits you to confirm a signature in opposition to a public key within the lock script in opposition to arbitrary chunks of that transaction because it’s being constructed. This might in the end allow the creation of open-ended UTXOs that anybody can spend, so long as the spending transaction meets sure standards, resembling a particular variety of cash despatched to a particular tackle. Mix this with the fact of OP_RETURN-based property, and this begins to maneuver into decentralized change (DEX) territory.
A number of the worst incentive distortion points which have emerged on different blockchains in the end stem from the creation of DEXes on these chains. Having direct non-interactive change performance on the blockchain is without doubt one of the worst types of MEV, particularly when the potential exists for miners to lock of their income over a number of transactions within the span of a single block, quite than truly should bear the revenue. threat of a place spanning a number of blocks earlier than it’s closed and income are realized.
A part of the motion behind Taproot Wizards is “bringing again the innovation.” Which means that the teachings discovered in shitcoin land additionally find yourself in Bitcoin. Whereas I firmly reject the concept something helpful has been developed up to now decade on cash apart from the essential idea of zero-knowledge proofs, this more and more vocal mantra ignores an enormous a part of that dynamic, even in the event you disagree with my place there: there are classes to be discovered about what NOT to do and what to do.
DEXes are one of many issues NOT to do. Nothing has brought about a lot chaos, volatility within the dynamics of the charges (which we have to easy out over time for the sustainability of the second layers), and simply incentive chaos in all places relating to the essential consensus layers of those protocols and their diploma of centralization . The concept we must always rush to carry these sorts of issues to Bitcoin, or make them worse by introducing a approach to reliably embed Bitcoin property in a extra dynamic and versatile method, is downright insane. This to me speaks of enormous teams of people that have discovered nothing from watching what has occurred on different blockchains over the previous 5 years.
Without end chained by the cat
Wanting on the above dynamic between CSFS + CAT, it is price declaring that Reardencode’s current LNHANCE proposal (CTV + CSFS + Inside Key) gives a path to giving us eltoo for Lightning in a method that primarily makes use of block house -more environment friendly than utilizing APO. If this argument, primarily based on proof-of-concepts, in the end wins over Lightning builders who need LN symmetry to simplify Lightning channel administration and deployment upkeep, we may very nicely undertake CSFS within the course of concerned. If OP_CAT was energetic earlier than, it can’t be prevented that the kinds of dangerous unwanted effects of the 2 proposals are mixed.
This may apply to any tender fork proposal sooner or later if OP_CAT had been ever activated. It might be unimaginable to flee the unwanted effects or use circumstances made potential by combining OP_CAT with no matter new proposals come sooner or later. By itself, OP_CAT is clunky, inefficient and quite pointless. However when mixed with different OPs it begins to develop into stupidly versatile and highly effective. This may be a dynamic we may by no means escape, and options that might show essential to Bitcoin’s scalability sooner or later may inevitably include monumental downsides and dangers just by advantage of current. from 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 methods of doing issues, quite than wanting by means of way more environment friendly and focused proposals? I might say no.
Meme campaigns could be enjoyable, I do know. They promote a way of group and involvement; it’s 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 always decide Bitcoin’s improvement course of. They are often enjoyable, they usually may even be viciously merciless in slicing straight to the guts of points individuals dance round or query. However they’re in some ways horrible at capturing nuance and complexity.
Attempting to drive the consensus of a community like Bitcoin primarily based solely on the worth of a meme, quite than a reasoned consideration of proposals and their implications, is a catastrophe ready to occur. The conservatism and warning of Bitcoin improvement have saved it on the forefront of this house, whereas shitcoins have come and gone, imploding within the penalties of their fly-by-night carefree improvement angle. As a lot as Bitcoin desperately wants to interrupt out of its present rut of stagnation and lack of progress, turning to uncritical memes and music movies isn’t the way in which to do it. It threatens to destroy what made Bitcoin useful within the first place: its stable and conservative basis.
