Yesterday might be a good day for cats to come out and bask in the sun, at least, in the Bitcoin ecosystem. In one day, we saw three Bitcoin FT protocols driven by OP_CAT - CAT 20 on Fractal, CAT NIP from the "Quantum Cat" team, and "Danny CAT 20" from the "Moto Series".

Among these three, CAT20 on Fractal has already been launched and is in full swing. The price of $FB once exceeded 30 US dollars. When I wrote this article, the miner fee on the Fractal chain was as high as 2000 sats/vb.

The CAT NIP of the "Quantum Cat" team is just an official announcement, and its implementation will have to wait until the OP_CAT of the Bitcoin mainnet is resurrected.

The "Danny CAT 20" of the "Moto Series" was proposed by Moto swap and OP_NET founder @ bc1 plainview 2 hours after the release of CAT 20. He said that he was the first to propose the idea of ​​OP_CAT driving the Bitcoin FT protocol. I will not elaborate on my opinion here, and I will talk about it when we discuss it next.

Let's start with the already playable CAT20 on Fractal.

CAT20

CAT20 was not that popular when it was discovered and spread by players in the early days, because until last night, I could still get some with a fee of 300-500 sats/vb. It really became popular because at about 11 o'clock last night, a "CAT20" column suddenly appeared on Fractal's block browser, and I was completely FOMO.

The data here has not been moved since it came out last night, so it is hard to tell how long it will take for $CAT to finish.

If the price of $FB is 30 U, and the fee rate is raised to 2000 sats/vb, the cost of a single ticket is close to 1 U, which means that in this case, $CAT is actually "purchased" based on the market value of 21 million US dollars.

The technical documentation of CAT 20 is quite professional, and the Github page is also quite neat. It is a FT protocol driven by OP_CAT technology. It is difficult to come up with something of this level if it is not an individual or team who has deeply studied Bitcoin technology.

What does "FT protocol driven by OP_CAT technology" mean? The answer in the official document is, "Any rules governing the token casting process are executed in smart contracts." Based on this, CAT20 has these features (please refer to the official document for more features)

  • No assets will be burned. You can directly use the UTXO used to mint tokens to continue minting tokens, because in essence, CAT20 is equivalent to writing data in UTXO and then the smart contract handles it. In the past, we usually understood the burning of assets as "colored coins" - I spent a UTXO with an inscription or "colored coin", and I can never get it back. But CAT20 is not like this. The on-chain data cannot be lost, and the contract handles changes by checking the on-chain data (transactions). Our UTXO is actually spent on contract interactions, like ERC-20.
  • Tickers are repeatable. Although tickers are repeatable, the txid and output index of each token in the genesis transaction are different. Together, they constitute a unique tokenid for a token, which is used to distinguish different tokens with the same ticker.
  • The minting rules are more free. There are no artificial regulations. It all depends on how the contract is written when the token is deployed. Some use cases mentioned in the official documentation include pre-sale, pre-mining, PoW mining, minting by designated token holders, staking minting, etc.

The CATNIP of the "Quantum Cat" team is similar to CAT20 in implementation, so in the following CATNIP section, I would like to focus on the potential huge impact of this thing on the Bitcoin ecosystem.

CATNIP

First of all, I want to remind everyone that CAT NIP will only be launched after the official resurrection of OP_CAT on the Bitcoin mainnet. Before that, there will be no way to participate. This is not like Rune, which can be "preempted" by imitating Casey's idea. The reason is actually explained in the CAT 20 section above - without OP_CAT, it is impossible to achieve "any rules governing the token casting process are executed in smart contracts."

When I saw CATNIP, my first thought was that @udiWertheimer seemed to have finally shown his "fangs" and wanted to "break away from the Ordinals"...

Why do you say that? Take a look at his tweet:

He said that the user experience of BRC-20 and Runes disappointed most Crypto enthusiasts. Although Ordinals and inscriptions are widely regarded as NFT implementations superior to other chains, BRC-20 and Runes do not meet the FT protocol standards on other chains. The reason is that Bitcoin's consensus (nodes and miners) do not know their existence, and Runes must bypass restrictions through code tricks and "cheat" (not attack, just a description) to be implemented on the Bitcoin network. This is why the UTXO of Runes must be cut, otherwise transactions cannot achieve partial purchases, and it is impossible to have AMMs and liquidity pools.

If Bitcoin's consensus accepts OP_CAT, there will be no need to try every possible way to "cheat", and more can be achieved.

Since the birth of Ordinals, most of the Bitcoin ecosystem innovations have revolved around Ordinals, including FT and N FT. With Udi's move, perhaps the attention of the Bitcoin ecosystem will be split in half, with one half being OP_CAT and FT, and the other half being Ordinals and N FT.

If OP_CAT on the Bitcoin mainnet is successfully resurrected, one of the biggest beneficiaries will undoubtedly be the "Great Wizard" and "Quantum Cat" teams and holders. Even now, we can guess the two benefits of the holders of these two projects - the first Token of CAT NIP will be airdropped to "Great Wizard" and "Quantum Cat", which is a direct benefit; mobilizing the community to lead the OP_CAT resurrection movement and ultimately succeed, and the status of the NFT project will be difficult for anyone to reach, which is an indirect benefit.

In addition to enthusiasm, I think they also have practical reasons to revive OP_CAT. After all, "The Great Wizard" received $7.5 million in financing.

The short-term follow-up development will be interesting. Will Udi have a debate with Ordinals supporters (or even Casey)? CAT20 on Fractal already has a first-mover advantage. Will there be competition between the two, for example, CAT20 will be launched on the mainnet in the future? And will this lead to a new wave of "China and foreign countries do not take over each other"?

Danny CAT20

Compared with the above two, this contestant is really more "fucking"... To be honest, I was confused after reading @ bc1 plainview's tweet - Brother, how dare you say that you invented CAT20 a month ago...

There is no professional technical documentation like CAT 20, nor even a tweet that elaborates on the implementation process like CAT NIP. There is only this Telegram screenshot. OK, it doesn’t matter. Let me explain the idea behind this picture to you - it actually uses OP_CAT to string together several fields of the Mint inscription. OK, I have invented the OP_CAT version of BRC-20.

This is totally unrelated to CAT 20. In essence, this thing is the same as BRC-20, built on the Ordinals protocol, so he said that it must wait until the Ordinals protocol is activated on Fractal at block height 21000 before it can be launched. Secondly, CAT 20 and CAT NIP both use contracts to drive the entire FT protocol, and this Danny CAT 20 is actually driven by inscriptions, but the way of creating casting inscriptions has been changed, and the words on the casting inscriptions are strung together using OP_CAT...

It's like a piece of beef. CAT20 and CATNIP are exploring how to upgrade the pot into an alchemy furnace and make the beef into Tang Monk meat. The big brother came out and said, steak can be fried as a whole, cut into pieces, skewered and grilled, I am a player of the same level as you...

It’s time to put an end to the opportunistic “plate-making innovation”.

Conclusion

CAT 20 and CAT NIP are definitely exciting for me. I wanted to write about OP_CAT before, but the technical principles are really obscure, and there are no direct use cases that can be explained and shared with everyone. With the emergence of these two, I think we will see more OP_CAT applications.

Ordinals opened the door to Bitcoin innovation and exploration, but the road is long and arduous. It would be lonely and abnormal if only Ordinals existed. We are happy to see more exploration. For Fractal, the emergence of CAT20 is an excellent interpretation of its "experimental field" positioning, and it also makes me look forward to the future development of Fractal.
