<p class="wysiwyg-text-align-justify"><span class="wysiwyg-color-black" style="font-weight: 400;">由于以太坊主网（即 Layer1）上交易严重拥堵，交易费用居高不下，开发者提出了 Layer2 以改善以太坊网络性能，提升交易处理速度。</span></p>
<p class="wysiwyg-text-align-justify"><span class="wysiwyg-color-black"><span style="font-weight: 400;">Arbitrum Nova 是 Arbitrum 开发团队 Offchain Labs 基于 </span><a href="https://developer.offchainlabs.com/docs/AnyTrust"><span style="font-weight: 400;">AnyTrust</span></a><span style="font-weight: 400;"> 技术推出的专为高交易量应用程序设计的全新 </span><a href="/pages/support.html/articles/4414704940569"><span style="font-weight: 400;">Layer2</span></a><span style="font-weight: 400;"> 网络。Arbitrum Nova 于 2022 年 8 月 10 日正式上线，采用 AnyTrust 技术，具有费用低和速度快等特点，支持通用区块链用例、游戏和社交应用。</span></span></p>

<p class="wysiwyg-text-align-justify"><span class="wysiwyg-color-black"><span style="font-weight: 400;">Arbitrum Nova 基于 </span><a href="https://developer.offchainlabs.com/docs/AnyTrust"><span style="font-weight: 400;">AnyTrust</span></a><span style="font-weight: 400;"> 技术打造，通过数据可用性委员会 (DAC) 的新安全模型实现超低交易费用。</span></span></p>
<ul class="wysiwyg-text-align-justify">
<li style="font-weight: 400;" aria-level="1"><span class="wysiwyg-color-black"><strong>AnyTrust：</strong><span style="font-weight: 400;">AnyTrust 是 Arbitrum Nitro 技术的一种变体，它通过接受温和的信任假设来降低成本。</span></span></li>
<li style="font-weight: 400;" aria-level="1"><span class="wysiwyg-color-black"><strong>数据可用性委员会 (DAC)：</strong><span style="font-weight: 400;">该委员会有 N 名成员，AnyTrust 技术假设其中至少有 2 名是诚实的。如有 N-1 个委员会成员承诺提供对某些数据的访问权限，则至少有 1 个承诺方必须诚实，确保数据可用，以保证 Rollup 协议能够正常运行。<br></span>如果委员会不签名或一群委员会成员崩溃或拒绝合作，通过回退到标准 Rollup 协议，链仍然可以运行：数据将发布在 L1 以太坊链上，提款将有一个等待期，就像在标准 Rollup 上一样——直到委员会恢复运行，然后链将无缝切换回更便宜、更快的模式。</span></li>
<li style="font-weight: 400;" aria-level="1"><span class="wysiwyg-color-black"><strong>数据可用性证明（DACert）：</strong><span style="font-weight: 400;">排序器（Sequencer）将数据压缩并打包后提交给数据可用性委员会，并请求一份数据可用性证明。当排序器接收到委员会给出的证明后会将其在以太坊上发布，作为数据可用性的承诺。<br></span><span style="font-weight: 400;">与未使用 AnyTrust 技术的链相比，Arbitrum Nova 发布至以太坊的不是完整的数据区块，而是精简的数据可用性证明，从而节省了 Abitrum 网络上最大的一笔开支，使用户能够享受超低的交易费用。</span></span></li>

<h3 id="h_01HPXP9PXR6APJ36P6DDKFPE3Q" class="wysiwyg-text-align-justify"><span class="wysiwyg-color-black" style="font-weight: 400;">Layer2</span></h3>
<p class="wysiwyg-text-align-justify"><span class="wysiwyg-color-black" style="font-weight: 400;">为了解决以太坊的可拓展性问题，开发者提出了两个方向的解决方案，Layer2 和分片（以太坊未来的一个重要升级）。Layer2 字面意思是二层网络，相对的，当前的以太坊主网也称为一层网络（Layer1），二层网络也就是基于当前以太坊主网的一个系统。</span></p>
<p class="wysiwyg-text-align-justify"><span class="wysiwyg-color-black" style="font-weight: 400;">Layer2 方案主要是从减轻 Layer1 负担的角度出发，将 Layer1 的大量计算需求搬到 Layer2 上。</span></p>
<p class="wysiwyg-text-align-justify"><span class="wysiwyg-color-black" style="font-weight: 400;">主流 Layer2 方案有 ZK Rollup、Optimistic Rollup、Plasma、State Channels（状态通道）、Validium 等。</span></p>
<h3 id="h_01HPXP9PXRF2CDJJ8H12FWVD4J" class="wysiwyg-text-align-justify"><span class="wysiwyg-color-black" style="font-weight: 400;">Optimistic Rollup</span></h3>
<p class="wysiwyg-text-align-justify"><span class="wysiwyg-color-black" style="font-weight: 400;">Rollup 中文叫做卷叠，是一种以太坊扩容方案的统称。Rollup 通过将链上计算转移至链下（二层网络），但同时将每笔交易的部分数据保留在链上达到提升以太坊网络性能的目的。</span></p>
<p class="wysiwyg-text-align-justify"><span class="wysiwyg-color-black" style="font-weight: 400;">Rollup 方案主要分为两种：ZK Rollup 和 Optimistic Rollup。ZK Rollup 是采用零知识证明的 Rollup 方案，但由于 ZK Rollup 存在无法良好支持智能合约，生成零知识证明耗时较长的问题，2019 年 6 月，Optimistic Rollup 方案被提出。这个方案中去除了零知识证明，增加了惩罚机制，来达到保障数据安全性（略低于 ZK Rollup 方案）的同时又可以更方便地支持通用性智能合约的目的。</span></p>
<p class="wysiwyg-text-align-justify"><span class="wysiwyg-color-black" style="font-weight: 400;">Optimistic Rollup 方案采用了 OVM（Optimistic 虚拟机），OVM 是功能完备、与 EVM（以太坊虚拟机）基本兼容的环境。通过 OVM，将 DApp 移植到 Layer2 变得简单，而且也使得项目方无需部署各种 Layer2 扩容方案，而只需接入 OVM，就可以使用其中的各类 Layer2 结构。</span></p>

Nova 简介\n由于以太坊主网（即 Layer1）上交易严重拥堵，交易费用居高不下，开发者提出了 Layer2 以改善以太坊网络性能，提升交易处理速度。\nArbitrum Nova 是 Arbitrum 开发团队 Offchain Labs 基于 AnyTrust 技术推出的专为高交易量应用程序设计的全新 Layer2 网络。Arbitrum Nova 于 2022 年 8 月 10 日正式上线，采用 AnyTrust 技术，具有费用低和速度快等特点，支持通用区块链用例、游戏和社交应用。\n本文将着重介绍 Arbitrum Nova，如果你对 Arbitrum One 感兴趣，可点此了解更多。\n工作原理\nArbitrum Nova 基于 AnyTrust 技术打造，通过数据可用性委员会 (DAC) 的新安全模型实现超低交易费用。\n\nAnyTrust：AnyTrust 是 Arbitrum Nitro 技术的一种变体，它通过接受温和的信任假设来降低成本。\n数据可用性委员会 (DAC)：该委员会有 N 名成员，AnyTrust 技术假设其中至少有 2 名是诚实的。如有 N-1 个委员会成员承诺提供对某些数据的访问权限，则至少有 1 个承诺方必须诚实，确保数据可用，以保证 Rollup 协议能够正常运行。如果委员会不签名或一群委员会成员崩溃或拒绝合作，通过回退到标准 Rollup 协议，链仍然可以运行：数据将发布在 L1 以太坊链上，提款将有一个等待期，就像在标准 Rollup 上一样——直到委员会恢复运行，然后链将无缝切换回更便宜、更快的模式。\n数据可用性证明（DACert）：排序器（Sequencer）将数据压缩并打包后提交给数据可用性委员会，并请求一份数据可用性证明。当排序器接收到委员会给出的证明后会将其在以太坊上发布，作为数据可用性的承诺。与未使用 AnyTrust 技术的链相比，Arbitrum Nova 发布至以太坊的不是完整的数据区块，而是精简的数据可用性证明，从而节省了 Abitrum 网络上最大的一笔开支，使用户能够享受超低的交易费用。\n\n特点\n\n超低的交易费用\n专为高交易量的应用程序设计\n通过加密技术保障代币拥有以太坊主网级别的安全性\n用户代币自持\nEVM 兼容\n\n了解更多\n\n相比其他 Layer2 Rollup 方案，Arbitrum 好在哪里？\nLayer 2 能否解决以太坊拥堵问题？\nVitalik：Rollup 不完全指南（精选）\n\n使用 Arbitrum Nova\n以 imToken 为例，首先下载安装 imToken 并创建 / 导入钱包，下载链接：https://token.im\n注：点击检查网站证书安全性\n创建 Arbitrum Nova 账户\n点击「我」-「钱包管理」-「添加账户」，勾选 Arbitrum Nova 网络并确认，返回钱包首页即可进入刚创建好的 Arbitrum Nova 账户进行转账、收款等操作并体验它的生态应用。\n\n详细教程：如何在 imToken 使用 Arbitrum Nova？\n学习\nLayer2\n为了解决以太坊的可拓展性问题，开发者提出了两个方向的解决方案，Layer2 和分片（以太坊未来的一个重要升级）。Layer2 字面意思是二层网络，相对的，当前的以太坊主网也称为一层网络（Layer1），二层网络也就是基于当前以太坊主网的一个系统。\nLayer2 方案主要是从减轻 Layer1 负担的角度出发，将 Layer1 的大量计算需求搬到 Layer2 上。\n主流 Layer2 方案有 ZK Rollup、Optimistic Rollup、Plasma、State Channels（状态通道）、Validium 等。\nOptimistic Rollup\nRollup 中文叫做卷叠，是一种以太坊扩容方案的统称。Rollup 通过将链上计算转移至链下（二层网络），但同时将每笔交易的部分数据保留在链上达到提升以太坊网络性能的目的。\nRollup 方案主要分为两种：ZK Rollup 和 Optimistic

方案被提出。这个方案中去除了零知识证明，增加了惩罚机制，来达到保障数据安全性（略低于 ZK Rollup 方案）的同时又可以更方便地支持通用性智能合约的目的。\u003c/span\u003e\u003c/p\u003e\n\u003cp class=\"wysiwyg-text-align-justify\"\u003e\u003cspan

Nova 简介\n由于以太坊主网（即 Layer1）上交易严重拥堵，交易费用居高不下，开发者提出了 Layer2 以改善以太坊网络性能，提升交易处理速度。\nArbitrum Nova 是 Arbitrum 开发团队 Offchain Labs 基于 AnyTrust 技术推出的专为高交易量应用程序设计的全新 Layer2 网络。Arbitrum Nova 于 2022 年 8 月 10 日正式上线，采用 AnyTrust 技术，具有费用低和速度快等特点，支持通用区块链用例、游戏和社交应用。\n本文将着重介绍 Arbitrum Nova，如果你对 Arbitrum One 感兴趣，可点此了解更多。\n工作原理\nArbitrum Nova 基于 AnyTrust 技术打造，通过数据可用性委员会 (DAC) 的新安全模型实现超低交易费用。\n\nAnyTrust：AnyTrust 是 Arbitrum Nitro 技术的一种变体，它通过接受温和的信任假设来降低成本。\n数据可用性委员会 (DAC)：该委员会有 N 名成员，AnyTrust 技术假设其中至少有 2 名是诚实的。如有 N-1 个委员会成员承诺提供对某些数据的访问权限，则至少有 1 个承诺方必须诚实，确保数据可用，以保证 Rollup 协议能够正常运行。如果委员会不签名或一群委员会成员崩溃或拒绝合作，通过回退到标准 Rollup 协议，链仍然可以运行：数据将发布在 L1 以太坊链上，提款将有一个等待期，就像在标准 Rollup 上一样——直到委员会恢复运行，然后链将无缝切换回更便宜、更快的模式。\n数据可用性证明（DACert）：排序器（Sequencer）将数据压缩并打包后提交给数据可用性委员会，并请求一份数据可用性证明。当排序器接收到委员会给出的证明后会将其在以太坊上发布，作为数据可用性的承诺。与未使用 AnyTrust 技术的链相比，Arbitrum Nova 发布至以太坊的不是完整的数据区块，而是精简的数据可用性证明，从而节省了 Abitrum 网络上最大的一笔开支，使用户能够享受超低的交易费用。\n\n特点\n\n超低的交易费用\n专为高交易量的应用程序设计\n通过加密技术保障代币拥有以太坊主网级别的安全性\n用户代币自持\nEVM 兼容\n\n了解更多\n\n相比其他 Layer2 Rollup 方案，Arbitrum 好在哪里？\nLayer 2 能否解决以太坊拥堵问题？\nVitalik：Rollup 不完全指南（精选）\n\n使用 Arbitrum Nova\n以 imToken 为例，首先下载安装 imToken 并创建 / 导入钱包，下载链接：https://token.im\n注：点击检查网站证书安全性\n创建 Arbitrum Nova 账户\n点击「我」-「钱包管理」-「添加账户」，勾选 Arbitrum Nova 网络并确认，返回钱包首页即可进入刚创建好的 Arbitrum Nova 账户进行转账、收款等操作并体验它的生态应用。\n\n详细教程：如何在 imToken 使用 Arbitrum Nova？\n学习\nLayer2\n为了解决以太坊的可拓展性问题，开发者提出了两个方向的解决方案，Layer2 和分片（以太坊未来的一个重要升级）。Layer2 字面意思是二层网络，相对的，当前的以太坊主网也称为一层网络（Layer1），二层网络也就是基于当前以太坊主网的一个系统。\nLayer2 方案主要是从减轻 Layer1 负担的角度出发，将 Layer1 的大量计算需求搬到 Layer2 上。\n主流 Layer2 方案有 ZK Rollup、Optimistic Rollup、Plasma、State Channels（状态通道）、Validium 等。\nOptimistic Rollup\nRollup 中文叫做卷叠，是一种以太坊扩容方案的统称。Rollup 通过将链上计算转移至链下（二层网络），但同时将每笔交易的部分数据保留在链上达到提升以太坊网络性能的目的。\nRollup 方案主要分为两种：ZK Rollup 和 Optimistic Rollup。ZK Rollup 是采用零知识证明的 Rollup 方案，但由于 ZK Rollup 存在无法良好支持智能合约，生成零知识证明耗时较长的问题，2019 年 6 月，Optimistic Rollup 方案被提出。这个方案中去除了零知识证明，增加了惩罚机制，来达到保障数据安全性（略低于 ZK Rollup 方案）的同时又可以更方便地支持通用性智能合约的目的。\nOptimistic Rollup 方案采用了 OVM（Optimistic 虚拟机），OVM 是功能完备、与 EVM（以太坊虚拟机）基本兼容的环境。通过 OVM，将 DApp 移植到 Layer2 变得简单，而且也使得项目方无需部署各种 Layer2 扩容方案，而只需接入 OVM，就可以使用其中的各类 Layer2 结构。\n开发团队 Offchain Labs\nArbitrum Nova 的开发团队 Offchain Labs 是一家专注于企业级应用的区块链初创公司，总部位于纽约。\nOffchain Labs 的联合创始人 Ed Felten 是普林斯顿大学的计算机科学教授和奥巴马白宫前首席技术官。他在 2018 年秋天和其他三位联合创始人创办了 Offchain Labs。\nArbitrum Nova 浏览器\nArbitrum Nova 区块浏览器是一个查询 Arbitrum Nova
