Za meme ili ne za meme: MAČAK
Je li doista iznenađujuće, s obzirom na to da su mačke u biti dominirale internetom posljednja dva desetljeća, da su mačji memi konačno preuzeli Bitcoin space as well in the last few weeks? Cats are the most viral meme on the internet, so it's not shocking in the least bit that the Taproot Wizards have leaned into it, reinforced by the trolling Luke over his “dietary choices.”
The question has to be asked though, are meme campaigns really how we want to go about deciding and discussing consensus changes to a protocol as valuable as Bitcoin? I’ve seen numerous music videos, campaigns to go out in the world and “educate” people on OP_CAT, and the whole “Quest” system that Taproot Wizards has launched taking place…but the reality is the vast majority of this content that I have seen has been incredibly superficial.
Rijndael, “Artificer” u Taproot Wizardsu i jedan od rijetkih ljudi, ako ne i jedina osoba, koja zapravo prtlja i igra se s OP_CAT-om kako bi izradila primjere slučajeva upotrebe, napravio je demo skripte ugovora temeljene na OP_CAT-u.
This script enforces a specific amount of Bitcoin be sent to a specific address, and by consensus there is no other way to spend these coins except with a transaction that meets those exact conditions. Look at the size of this script:

To je ono što je potrebno za emulaciju CHECKTEMPLATEVERIFY. Ekvivalentna skripta koja koristi CTV bila bi jednostavno:
CTV .
Pitam, koja je vrijednost nečega poput OP_CAT u oponašanju slučaja ugovora osnovnih predložaka (stvari koje zahtijevaju da transakcija potrošnje ispuni određene uvjete definirane unaprijed da bi bila važeća) poput ovoga? Točno znamo kako postupati sa shemama koje provode predložak na transakcijama koje troše izlaz zaključan na ugovor predloška i imamo više prijedloga za njih. CTV, TXHASH, OP_TX, pa čak i APO mogu emulirati ove sheme ubacivanjem potpisa u izlaz zaključavanja transakcije po cijenu dodatnih 64 bajta.
What actual use is OP_CAT in “experimenting” to meet the needs of a class of use cases that are mature enough in design that there are at least 4 covenant proposals that can handle those use cases with a tiny fraction of the data cost? “Oh, we want to experiment with CAT because it’s flexible!” You want to use 30 OP calls to do something that can be done in one? That is a reason to actually enact a consensus change to Bitcoin? The logic of that is beyond absurd.
Umanjivanje rizika
U vakuumu se OP_CAT prodaje kao "jednostavno spajanje dvaju nizova", a mnogi memeovi pokušavaju ga uokviriti kao "kako to može biti opasno?" Ovo je krajnje neiskren narativ koji okružuje prijedlog i potpuno zanemaruje kako je u interakciji s drugim postojećim i budućim aspektima scenarija.
In particular CSFS + CAT opens a massive amount of possibilities in terms of what can be done with Bitcoin script, not all of it necessarily positive. CSFS allows you to verify a signature on an arbitrary piece of data in the course of executing a script, and CAT allows you to “glue” different pieces of data together on the stack. These two things create a masivan design space for what it is possible to do with Bitcoin.
Jedan konkretan primjer bio bi potencijal za nametanje iznosa ili odnosa između različitih iznosa specifičnih ulaza i izlaza u transakciji. CAT vam omogućuje da izgradite hash transakcije od pojedinačnih dijelova na stogu, a CSFS vam omogućuje da provjerite potpis prema javnom ključu u skripti za zaključavanje prema proizvoljnim dijelovima te transakcije dok se sastavlja. To bi u konačnici moglo omogućiti stvaranje otvorenih UTXO-ova koje svatko može potrošiti, sve dok transakcija potrošnje zadovoljava određene kriterije, poput slanja određene količine kovanica na određenu adresu. Kombinirajte ovo sa stvarnošću imovine temeljene na OP_RETURN, i ovo počinje ulaziti u područje decentraliziranih razmjena (DEX).
Some of the worst incentive distortion problems that have come to fruition on other blockchains ultimately stem from the creation of DEXes on those chains. Having direct non-interactive exchange functionality on the blockchain is one of the worst forms of MEV, especially when the potential exists for miners to lock-in their profit across multiple trades in the span of a single block, rather than having to actually carry the risk of a position across multiple blocks before closing it out and realizing profit.
Part of the movement behind Taproot Wizards is “bringing the innovation back.” I.e. that lessons learned in shitcoin land are coming home do Bitcoin, now while I firmly reject the notion that anything useful has been developed on other coins in the last decade other than the basic concept of zero knowledge proofs, this mantra getting louder ignores a massive component of that dynamic even if you disagree with my view there: postoje lekcije koje treba naučiti o tome što NE činiti, kao i o tome što činiti.
DEXes are one of the things NOT to do. Nothing has caused as much chaos, volatility in fee dynamics (which we need to smooth out over time for sustainability of second layers), and just all around incentive chaos regarding the base consensus layers of these protocols and their degree of centralization. The idea that we should rush to bring these types of problems to Bitcoin, or exacerbate them by introducing a way to trustlessly embed the bitcoin asset into them in more dynamic and flexible ways, is frankly insane. This to me speaks of large swaths of people who haven’t learned anything from watching what happened on other blockchains in the last half decade or so.
Zauvijek okovan mačkom
Looking at the dynamic above between CSFS + CAT, it is worth pointing out that Reardencode’s recent LNHANCE proposal (CTV + CSFS + Internal Key) offers a path to give us eltoo for Lightning in a way that is actually more blockspace efficient than using APO. If this argumentation, and build out of proof of concepts, winds up winning over Lightning developers who want LN symmetry in order to simplify Lightning channel management and implementation maintenance, we very well could wind up getting CSFS in the process. If OP_CAT were active prior to this, then there is no way to avoid the types of detrimental side effects of the two proposals being combined.
This would hold true for every soft fork proposal going forward if OP_CAT were ever activated. It would be impossible to escape whatever side effects or use cases were enabled by combining OP_CAT with whatever new proposals come in future. On its own OP_CAT is clunky, inefficient, and rather pointless. But in combination with other OPs it begins to get stupidly flexible and powerful. This would be a dynamic we would never be able to escape, and features that might wind up being critically necessary in the future for Bitcoin’s scalability could inescapably come with massive downsides and risks simply because of the existence of OP_CAT.
Je li ovo stvarnost u koju želimo ući samo zbog meme kampanje? Zato što se ljudi žele petljati s krajnje neučinkovitim načinima obavljanja stvari umjesto da pregledaju mnogo učinkovitije i svrhovitije prijedloge? rekao bih da nije.
Meme campaigns can be fun, I know this. They foster a sense of community and involvement, it's an inherent and inescapable part of the internet and the numerous cultures that exist on it. But this is not how we should be deciding the development process of Bitcoin. They can be fun, and they can even be viciously savage at stabbing directly to the heart of matters people dance around or equivocate on. But they are atrocious at capturing nuance and complexity in many regards.
Trying to steer the consensus of a network like Bitcoin purely based on the value of a meme, rather than reasoned consideration of proposals and their implications, is a disaster waiting to happen. The conservatism and caution of Bitcoin development is what has kept it at the forefront of this space as shitcoins have come and gone, imploding in the consequences of their fly by night carefree development attitude. As much as Bitcoin sorely needs to break out of its current rut of stagnation and lack of forward progress, devolving to uncritical memes and music videos is not how to do that. It risks destroying what made Bitcoin valuable in the first place, its solid and conservative foundation.
