Scroll：基于以太坊构建的第 2 层区块链，旨在提高可扩展性和效率

近年来，以太坊的可扩展性一直是区块链生态系统中最受争议的话题之一。其网络面临高拥塞和交易费用高的问题

In recent years, Ethereum’s scalability has been one of the most debated topics within the blockchain ecosystem. Its network has faced issues of high congestion and elevated transaction fees, especially when subjected to high demand. One of the latest proposals to tackle this problem is Scroll, a blockchain with interesting tools to improve efficiency and reduce costs.

近年来，以太坊的可扩展性一直是区块链生态系统中最受争议的话题之一。其网络面临着高拥堵和交易费用高昂的问题，尤其是在需求量很大的情况下。解决这个问题的最新提议之一是 Scroll，这是一个区块链，具有有趣的工具来提高效率和降低成本。

What is Scroll?

什么是滚动？

Scroll is a Layer 2 (L2) blockchain built on the Ethereum network, designed to improve scalability and efficiency through the implementation of zk-rollups. This scalability solution, operating off-chain from Ethereum’s main network, allows for faster and more cost-effective transaction processing, alleviating the load on the main chain and reducing transaction fees.

Scroll 是构建在以太坊网络上的第 2 层 (L2) 区块链，旨在通过实施 zk-rollups 来提高可扩展性和效率。这种可扩展性解决方案在以太坊主网络的链下运行，可以实现更快、更具成本效益的交易处理，减轻主链的负载并降低交易费用。

Its adoption of the zkEVM (Zero-Knowledge Ethereum Virtual Machine) concept gives it full compatibility with the Ethereum Virtual Machine (EVM). Thanks to this feature, Scroll can run decentralized applications (dApps) designed for Ethereum without developers having to modify the base code. This bytecode compatibility makes it easier for projects to migrate from ETH to SCR, ensuring a smooth transition for developers already familiar with the ETH environment.

它采用zkEVM（零知识以太坊虚拟机）概念，使其与以太坊虚拟机（EVM）完全兼容。得益于此功能，Scroll 可以运行为以太坊设计的去中心化应用程序（dApp），而无需开发人员修改基本代码。这种字节码兼容性使项目更容易从 ETH 迁移到 SCR，确保已经熟悉 ETH 环境的开发人员能够顺利过渡。

zkEVM AND zk-Rollups: The Heart of Scalability in Scroll

zkEVM 和 zk-Rollups：Scroll 中可扩展性的核心

The cornerstone of Scroll is its use of zkEVM, an advanced implementation of zk-rollups that not only enhances Ethereum’s scalability but also maintains full compatibility with the EVM. This means that developers can deploy smart contracts using any EVM-compatible language without needing to learn new languages or adapt their code. This flexibility removes the technical barriers that often exist in other solutions, which frequently require specialized programming languages and more complex processes.

Scroll 的基石是它对 zkEVM 的使用，这是 zk-rollups 的高级实现，不仅增强了以太坊的可扩展性，而且保持了与 EVM 的完全兼容性。这意味着开发人员可以使用任何 EVM 兼容语言部署智能合约，而无需学习新语言或调整其代码。这种灵活性消除了其他解决方案中经常存在的技术障碍，这些解决方案通常需要专门的编程语言和更复杂的流程。

How is Scroll’s Architecture Composed?

Scroll的架构是如何组成的？

Scroll’s architecture is composed of several interconnected elements that enable it to function as a zk-rollup solution on Ethereum. Below, we will explore each of these components in detail:

Scroll 的架构由多个相互关联的元素组成，使其能够充当以太坊上的 zk-rollup 解决方案。下面，我们将详细探讨每个组件：

* zkEVM: As mentioned earlier, Scroll is built upon the zkEVM technology, which provides it with complete compatibility with the Ethereum Virtual Machine (EVM). This allows developers to deploy smart contracts on Scroll using any EVM-compatible language without needing to modify their code.

* zkEVM：如前所述，Scroll 是基于 zkEVM 技术构建的，这使其与以太坊虚拟机（EVM）完全兼容。这使得开发人员可以使用任何 EVM 兼容语言在 Scroll 上部署智能合约，而无需修改代码。

* zk-Rollups: Scroll utilizes zk-rollups to bundle a large number of transactions off-chain before submitting them to Ethereum’s main network. This technique helps reduce gas fees and congestion on the main chain while enabling faster transaction processing times.

* zk-Rollups：Scroll 利用 zk-rollups 将大量链下交易捆绑在一起，然后将其提交到以太坊主网络。该技术有助于减少主链上的汽油费和拥堵，同时实现更快的交易处理时间。

* Testnet: Scroll currently operates a testnet where users can interact with the platform firsthand and participate in testing various decentralized applications (dApps) and projects.

* 测试网：Scroll 目前运营一个测试网，用户可以直接与平台交互并参与测试各种去中心化应用程序 (dApp) 和项目。

* Scroll Token (SCR): Role, Utility and Relevance

* Scroll Token (SCR)：角色、实用性和相关性

The SCR token plays a crucial role, not only as an incentive tool for network participation but also as a mechanism to ensure efficient and decentralized operation. Let’s explore how this cryptocurrency integrates within the network architecture and the advantages it offers to users and developers.

SCR代币发挥着至关重要的作用，不仅作为网络参与的激励工具，而且作为确保高效和去中心化运行的机制。让我们探讨一下这种加密货币如何集成到网络架构中以及它为用户和开发人员提供的优势。

It is primarily used for two purposes: participation in the decentralized governance of the network and as a medium to pay transaction fees within the ecosystem.

它主要用于两个目的：参与网络的去中心化治理以及作为生态系统内支付交易费用的媒介。

Its Impact on the Ethereum Ecosystem

它对以太坊生态系统的影响

The implementation of Scroll within the Ethereum ecosystem has the potential to alleviate some of the network’s biggest problems, especially those related to scalability and high costs. Layer 2 solutions like SCR have become increasingly necessary to ensure the blockchain remains operational efficiently and accessibly.

在以太坊生态系统中实施 Scroll 有可能缓解网络的一些最大问题，特别是与可扩展性和高成本相关的问题。为了确保区块链保持高效和可访问性，像 SCR 这样的第 2 层解决方案变得越来越必要。

Thanks to Scroll, developers now have a scalability platform that not only improves the user experience but also enables the creation of more complex and feature-rich applications, taking advantage of its greater capacity at scale without the risk of congesting the main network.

得益于 Scroll，开发人员现在拥有了一个可扩展平台，不仅可以改善用户体验，还可以创建更复杂、功能丰富的应用程序，大规模利用其更大的容量，而无需担心主网络拥塞的风险。

Furthermore, it’s worth highlighting that Scroll has attracted a large developer community, as seen in the wide range of projects already being implemented on its testnet. This point is crucial to ensure the long-term sustainability and growth of the platform.

此外，值得强调的是，Scroll 吸引了庞大的开发者社区，从其测试网上已经实施的广泛项目即可看出。这一点对于确保平台的长期可持续性和增长至关重要。
