比特币的设计具有独特的特点，使其无法执行某些操作，这导致开发人员和用户在以太坊生态系统中寻找更绿色的牧场。然而，这样的缺点反而使比特币更安全、更稳定。 在关于比特币脚本协议语言的文章中，我们认为，由于比特币的指令集有限，许多应用程序不可能在比特币上实现。这就是为什么永远不会有比特币原生的DeFi应用程序，因为底层的智能合约(一个有趣的名字，指在区块链上自我执行和原生运行的小程序)需要一个完整的指令集。 然而，脚本允许创建称为原子交换的东西。你可能已经注意到，比特币开发者在为自己的产品寻找令人敬畏的名字方面几乎和苹果的营销部门一样有创造力。为了避免不必要的技术性问题，原子互换允许比特币在一次交易中与其他区块链的货币进行交换，如莱特币或以太坊，不需要中介。具体的机制涉及到哈希时间锁定合约，超出了本研究的范围。 只有两个项目提供基于比特币的分布式金融服务——DeFiChain和Portal.finance。 
DeFiChain 通过每30分钟将加密资产存储到比特币区块链，DeFiChain使用一种智能的方式来保护自己链上的交易。DeFiChain自身网速很快，并通过扩展比特币的脚本语言来定制去开放式金融，可以在不破坏图灵完整性和安全性的情况下实现构建、质押和标记化功能，从而适应分散金融。 DeFiChain于2020年上线，并于2021年11月推出了从股票中创建数字代币的功能。目前当特斯拉（Tesla）、谷歌（Google）和其他股票与稳定币配对提供流动性时可获得高达400%的APR。 由于其快速的创新和巧妙的安全机制，DeFiChain的应用程序吸引了超过18亿美元的资产。 锁定在比特币DeFi上的总价值 Portal.finance尚未向公众公布。投资者可以启动白名单程序参与创建，Portal.finance宣布将为其开发投入6.5亿美元资金。 DeFiChain是唯一运行在比特币上的L2分布式交易平台，比特币的总价值(TVL)是相同的—18亿美元。对这个独特的领域感兴趣的人，建议留意Portal的开始和牵引力。 总结 从更诗意的角度来看，比特币似乎是现代加密资产的智慧之父。虽然它可能被认为是过时的，但它对核心价值观的严格坚持，使它天生值得信赖，并拥有巨大的权威。 DeFi已经掌控了比特币。虽然以太坊允许本地金融开发式应用程序(DApp)，但为交换区提供流动性的交易费用经常超过100美元，偶尔超过1000美元。以太坊之上的L2解决方案现在非常流行，所以没有理由认为L2的 DeFi比L1“不真实”。 作为一个整体，比特币仍然是加密资产的有效同义词，而Taproot、Lightning Network和layer2的DeFi意味着它不仅仅是第一种加密资产，它仍然是全球分布式金融市场区块链基础的强大竞争对手。 来源：金色财经 |
