Cardano揭露了红衣主教，这是一种比特币本地DAPP协议，以扩展其Fefi生态系统

Cardano揭开了Cardinal，这是一种新协议，旨在将比特币与其分散融资（DEFI）生态系统联系起来。

Cardano has built a protocol called Cardinal to connect Bitcoin with its decentralised finance (DeFi) ecosystem, aiming to provide decentralised access to DeFi tools for Bitcoin holders.

Cardano建立了一个名为Cardinal的协议，用于将比特币与其分散融资（DEFI）生态系统联系起来，旨在为比特币持有人分散访问DEFI工具。

Announced by founder Charles Hoskinson on 9 June, the launch was accompanied by a post from Roman Pellerin, Chief Technology Officer at Input Output Global (IOG), Cardano’s development arm.

该发布会由创始人查尔斯·霍斯金森（Charles Hoskinson）于6月9日宣布，伴随着Cardano开发部门Input Outper Global（IOG）首席技术官Roman Pellerin的帖子。

The protocol introduces a method for wrapping Bitcoin’s unspent transaction outputs (UTXOs), allowing them to circulate as pegged tokens on Cardano’s network. These tokens retain a one-to-one link with Bitcoin and can be burned at any point to redeem the original asset.

该协议介绍了一种包装比特币的未固定交易输出（UTXO）的方法，从而使其可以作为Cardano网络上的固定令牌作为固定的令牌进行循环。这些令牌保留了与比特币一对一的链接，并且可以在任何时候燃烧以兑换原始资产。

Cardinal allows Bitcoin users to access DeFi tools such as lending, staking, and borrowing without using centralised platforms or custodians. Its design prioritises decentralisation through a trust-minimised system that works as long as a single operator remains honest.

红衣主教允许比特币用户在不使用集中式平台或托管人的情况下访问诸如贷款，积分和借贷之类的Defi工具。它的设计通过信任最终化的系统优先考虑权力下放，只要单个操作员保持诚实，该系统就可以使用。

The system employs MuSig2, a cryptographic protocol that enables joint transaction signing by multiple parties. This enhances the platform’s resilience and removes the need for central trust authorities.

该系统采用Musig2，这是一种加密协议，可实现多方的联合交易签署。这增强了平台的弹性，并消除了中央信托当局的需求。

Cardinal also includes BitVMX, an off-chain computing system for handling advanced Bitcoin operations securely and efficiently. The integration with both Bitcoin’s scripting and Cardano’s smart contracts ensures programmable and secure asset transfers.

红衣主教还包括BITVMX，这是一种可牢固有效地处理高级比特币操作的链计算系统。与比特币的脚本和Cardano的智能合约的集成确保了可编程和安全的资产转移。

Pellerin confirmed that although the protocol is operational and has been used to wrap/unwrap the first ordinal on the two mainnets, it is not yet considered ready for full-scale development.

Pellerin确认，尽管该协议是运行的，并且已用于包装/解开两个mainnet上的第一个序数，但尚未被视为已准备好进行全尺度开发。

The Cardano DeFi sector has seen a decline, with total value locked dropping from US$415 million (AU$635.11 million) in May to US$334 million (AU$511.72 million) by 10 June, according to DefiLlama data. The team believes Cardinal could help by offering Bitcoin holders decentralised options.

根据Defillama数据，Cardano Defi行业的下降幅度下降，总价值从5月的4.15亿美元（6.351亿美元）下降到6月10日的3.3​​4亿美元（AU 5.1172亿美元）。该团队认为，红衣主教可以通过提供比特币持有者分散的选项来提供帮助。
