比特幣上的新 CAT 協議

新的 Covenant Attested Token (CAT) 協議基於比特幣的 UTXO，用於創建代幣。

Taproot Wizards co-founder Udi Wertheimer has proposed launching new CATNIP tokens, based on OP_CAT.

Taproot Wizards 聯合創始人 Udi Wertheimer 提議推出基於 OP_CAT 的新 CATNIP 代幣。

Runes were a mistake… but OP_CAT fixes this!

符文是一個錯誤…但 OP_CAT 修復了這個問題！

Introducing CATNIP: Bitcoin-native CAT-powered tokens.

隆重介紹 CATNIP：比特幣原生 CAT 驅動的代幣。

Most crypto enthusiasts have been left disappointed by the user experience of BRC-20s and Runes. While Ordinals and Inscriptions are largely considered to be a superior version of NFTs on Bitcoin, they both rely on third-party off-chain indicators to function, which introduces the risk of indicator inconsistency.

大多數加密貨幣愛好者對 BRC-20 和 Runes 的用戶體驗感到失望。雖然序數和銘文在很大程度上被認為是比特幣 NFT 的高級版本，但它們都依賴第三方鏈下指標來發揮作用，這會帶來指標不一致的風險。

In contrast, the Covenant Attested Token (CAT) protocol is validated by miners and uses smart contract covenants to handle the minting and transactions of tokens. It is implemented exclusively by Bitcoin Script on Bitcoin’s Layer-1, inheriting Bitcoin’s native Proof of Work security.

相比之下，契約證明代幣（CAT）協議由礦工驗證，並使用智能合約契約來處理代幣的鑄造和交易。它由比特幣腳本在比特幣的 Layer-1 上獨家實現，繼承了比特幣原生的工作量證明安全性。

notably, CAT tokens can be verified in Script, and most importantly, they can also be used in other smart contracts and in more complex and interconnected decentralized applications, such as DEXs based on AMM (Automated Market Makers), lending, and staking.

值得注意的是，CAT 代幣可以在腳本中進行驗證，最重要的是，它們還可以用於其他智能合約以及更複雜和互連的去中心化應用程序，例如基於AMM（自動做市商）的DEX、借貸和質押。

Furthermore, the CAT protocol enables the trustless bridging of assets between different blockchains, allowing dApps to operate on multiple chains.

此外，CAT 協議實現了不同區塊鏈之間資產的去信任橋接，允許 dApp 在多個鏈上運行。

With the new CAT protocol, it is possible to create both classic fungible tokens, with the CAT20 standard, and non-fungible tokens (NFTs) with the CAT721 standard.

透過新的 CAT 協議，可以創建符合 CAT20 標準的經典可替代代幣和符合 CAT721 標準的不可替代代幣（NFT）。

For the new CAT protocol to actually start being used on Bitcoin, OP_CAT must be reactivated.

為了讓新的 CAT 協定真正開始在比特幣上使用，必須重新啟動 OP_CAT。

OP_CAT was originally an opcode in Bitcoin that was disabled in 2010. Over the years, however, it has been proposed several times to reactivate it with a soft fork.

OP_CAT 最初是比特幣中的一個操作碼，於 2010 年被禁用。

Its main use is to allow the data provided by the creator of a script to be concatenated with the data provided by someone else who spends from that script.

它的主要用途是允許腳本創建者提供的數據與從該腳本消費的其他人提供的數據連接起來。

Hence, in its current state, the CAT protocol cannot yet be used on Bitcoin’s Layer-1 (its public blockchain), but Wertheimer’s proposal is not the only one that asks to reactivate OP_CAT.

因此，在目前的狀態下，CAT 協議尚不能在比特幣的 Layer-1（其公共區塊鏈）上使用，但 Wertheimer 的提案並不是唯一要求重新啟動 OP_CAT 的提案。

Specifically, Wertheimer proposed the CATNIP protocol to create tokens, stating that the protocol currently used to create and trade tokens on the Bitcoin blockchain, Rune, is a mistake, and that OP_CAT solves the problem.

具體來說，Wertheimer 提出了 CATNIP 協議來創建代幣，指出目前用於在比特幣區塊鏈上創建和交易代幣的協議 Rune 是一個錯誤，而 OP_CAT 解決了這個問題。

He says that the user experience with the BRC-20 protocol and Rune has been disappointing for most cryptocurrency enthusiasts, and that the source of the frustration is a fundamental problem with these protocols, which is that Bitcoin consensus (the nodes and miners) is unaware of their existence.

他表示，對於大多數加密貨幣愛好者來說，BRC-20 協議和Rune 的用戶體驗令人失望，而挫折感的根源在於這些協議的一個根本問題，即比特幣共識（節點和礦工）沒有意識到他們的存在。

All this leads to having to overcome cumbersome steps to exchange BTC for Rune or vice versa.

所有這些都導致​​必須克服繁瑣的步驟才能將 BTC 兌換成符文，反之亦然。

CATNIP solves this problem, thanks to the recursive covenants OP_CAT that already enables the Purrfect Vault. This would allow the creation of true native tokens on Bitcoin, usable within the Bitcoin Script. No other protocol for creating tokens on Bitcoin can currently do this.

CATNIP 解決了這個問題，這要歸功於已經啟用 Purrfect Vault 的遞歸契約 OP_CAT。這將允許在比特幣上創建真正的原生代幣，可在比特幣腳本中使用。目前沒有其他在比特幣上創建代幣的協議可以做到這一點。

The idea is that, when (and if) OP_CAT is reactivated on the Bitcoin mainnet, CATNIP will be especially useful for stablecoins.

這個想法是，當（並且如果）OP_CAT 在比特幣主網上重新啟動時，CATNIP 將對於穩定幣特別有用。

The new CAT protocol is already monopolizing the Fractal network.

新的 CAT 協定已經壟斷了 Fractal 網路。

In particular, Fractal claims to be the only scaling solution for Bitcoin that uses Bitcoin Core’s own code to scale recursively thanks to unlimited layers.

特別是，Fractal 聲稱是唯一使用 Bitcoin Core 自己的程式碼透過無限層進行遞歸擴展的比特幣擴展解決方案。

The mainnet went live just a few days ago, and it has a partnership with OKX Wallet.

主網前幾天上線，並與OKX錢包合作。

They are also working on a voting platform that will use OP_CAT, thus giving Fractal holders the possibility to vote on proposals.

他們也正在開發一個使用 OP_CAT 的投票平台，使 Fractal 持有者可以對提案進行投票。

It should be noted, however, that Fractal is not Bitcoin, but a crypto project based on the Bitcoin blockchain.

但要注意的是，Fractal 並不是比特幣，而是一個基於比特幣區塊鏈的加密項目。

So, as for the OP_CAT function, it has not yet been reactivated on Bitcoin, after being disabled in 2010, but on Fractal, for example, it is already available.

因此，至於 OP_CAT 功能，它在 2010 年被禁用後，尚未在比特幣上重新激活，但在 Fractal 等平台上，它已經可用。

The Bitcoin community will have to decide whether to re-add it, and to do so a soft fork similar in some ways to the one that introduced Taproot a few years ago will be needed.

比特幣社群將必須決定是否重新添加它，為此，需要在某些方面類似於幾年前引入 Taproot 的軟分叉。

If it is re-added, it will be possible to start using the CAT protocol also on Bitcoin’s Layer-1.

如果重新添加，則也可以在比特幣的 Layer-1 上開始使用 CAT 協定。

Thanks to the new CAT protocol, it will be possible, for example, to create tokens with CATNIP, or other similar protocols.

例如，借助新的 CAT 協議，可以使用 CATNIP 或其他類似協議創建代幣。

It will be possible to create both normal fungible tokens CAT-20 and NFTs in CAT-721 format.

可以創建普通的可替代代幣 CAT-20 和 CAT-721 格式的 NFT。

Currently, it is not possible to create tokens using native Bitcoin functions, so both creating and using them involves cumbersome processes and has limited potential.

目前，無法使用比特幣原生功能創建代幣，因此創建和使用它們都涉及繁瑣的過程並且潛力有限。

With protocols like CATNIP, even the Bitcoin blockchain will be able to allow the creation and transfer of tokens with native functions, making everything simpler and with much greater potential.

透過像 CATNIP 這樣的協議，甚至比特幣區塊鏈也將能夠允許創建和轉移具有本機功能的代幣，使一切變得更簡單並具有更大的潛力。

For example, one could create real DEXs on Bitcoin to allow the direct exchange of BTC into a stablecoin and vice

例如，人們可以在比特幣上創建真正的 DEX，以允許將 BTC 直接兌換成穩定幣，反之亦然。
