什么是 Nomic？
Nomic 是 Cosmos 生态中最令人期待 L1 之一。Cosmos 是一个由拥有主权的、可互操作的特定应用区块链组成的生态系统，它建立在 Tendermint 共识引擎之上，并通过 Cosmos SDK 连接不同的组件
归功于链间通信（IBC）通用标准协议，所有这些网络都可以自由地相互沟通和交换价值。由于所谓的 Peg Zone，该协议甚至允许非 Tendermint 网络与 Cosmos 生态系统通信，这就与 Pow 区块链（如比特币和以太坊）建立了桥梁
Nomic 的作用则是使 BTC 能够在整个 Cosmos 生态系统中自由地使用
它是如何工作的？
用户可以在协议内存入$BTC，以换取与 IBC 兼容的同种代币 $nBTC。在收到这个代币后，用户将能够在整个 Cosmos 生态系统中，使用 BTC 来进行 DeFi 操作。例如，用户可以开设一个由BTC 支持的抵押债务头寸，来借入其他代币，或通过在 LP 池内存入$nBTC 来参与流动性挖矿
Nomic 链将受到其原生 NOM 代币的保护，允许验证者及其委托人同时赚取NOM 的质押奖励和 BTC 过桥费
Nomic 的另一个特点是，它将是第一个不使用标准 Cosmos SDK 构建的 IBC 兼容链。Nomic 团队已经开发了一个新的高性能区块链应用框架，称为 Orga
Orga
Orga 是一个用 Rust 编写的新的确定性状态机框架，允许开发人员在 Tendermint 共识之上构建区块链应用程序。但是，是什么让 Orga 如此独特？
与 GO 相比，Orga 性能提高了 100 倍。Cosmos SDK 区块链的吞吐量受到应
用程序的限制，而这个新框架允许创建可以每秒处理超过 10K 次交易（TPS）的产品
得益于 Rust 编程语言，构建应用程序所需的代码少了 10 倍，在代码设计层面更加安全
Nomic 跟其他跨链桥有什么不同？
在解释为什么 Nomic 与其他跨链桥不同之前，我们必须了解与安全和密码学有关的两个关键特征
Schnorr 签名
Schnorr 签名是 Claus Schnorr 于 1989 年描述的数字签名方案，并拥有一项美国专利，于 2008 年到期。由于离散对数问题的假设难解性，所以这种签名方案的特点是简单性和安全性。它也是普遍采用的椭圆曲线操纵签名算法（ECDSA）的一个更有效的替代方案
借助 Schnorr 签名，可以轻松利用多重签名方案和批量验证
Taproot
Taproot 是比特币网络最重要的升级之一，旨在改善用户的隐私。除了解决交易隐私外，还减少了佣金，并允许创建更复杂的交易
Nomic 跨链桥
Nomic 是围绕公共网络比特币储备设计的。每个验证者都是储备金的签署者，储备金将通过储备金脚本在区块链网络中，并以去中心化的民主方式进行管理
Schnorr 签名允许 Nomic 中设立一个共同的比特币储备。该储备通过多重签名，由所有验证者们管理。
Taproot 将允许 Nomic 有效地实施储备脚本方案，为基金储备创造比特币支出条件
Nomic 将如何改变 DeFi？
通过让 BTC 在 Cosmos 生态系统中用去中心化的方式进行交易，Nomic 将促进新应用程序的产生：
基于超额抵押、低波动性、BTC 储备的稳定币。我们将能够建立一个基于 DAI 模型的 Cosmos 原生稳定币，但完全去中心化和抗审查
可以在不修改原始比特币协议的情况下利用比特币网络的智能合约
