Scroll：基於以太坊構建的第 2 層區塊鏈，旨在提高可擴展性和效率

近年來，以太坊的可擴展性一直是區塊鏈生態系統中最受爭議的話題之一。其網路面臨高擁塞和交易費用高的問題

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.

近年來，以太坊的可擴展性一直是區塊鏈生態系統中最受爭議的話題之一。其網路面臨高擁堵和交易費用高昂的問題，尤其是在需求量大的情況下。解決這個問題的最新提議之一是 Scroll，這是一個區塊鏈，具有有趣的工具來提高效率和降低成本。

What is Scroll?

什麼是滾動？

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 是構建在以太坊網路上的第 2 層 (L2) 區塊鏈，旨在透過實施 zk-rollups 來提高可擴展性和效率。這種可擴展性解決方案在以太坊主網路的鏈下運行，可實現更快、更具成本效益的交易處理，減輕主鏈的負載並降低交易費用。

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.

它採用zkEVM（零知識以太坊虛擬機器）概念，使其與以太坊虛擬機器（EVM）完全相容。由於此功能，Scroll 可以運行為以太坊設計的去中心化應用程式（dApp），而無需開發人員修改基本程式碼。這種字節碼相容性使專案更容易從 ETH 遷移到 SCR，確保已經熟悉 ETH 環境的開發人員能夠順利過渡。

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

zkEVM 和 zk-Rollups：Scroll 中可擴展性的核心

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 的基石是它對 zkEVM 的使用，這是 zk-rollups 的高級實現，不僅增強了以太坊的可擴展性，而且保持了與 EVM 的完全兼容性。這意味著開發人員可以使用任何 EVM 相容語言部署智慧合約，而無需學習新語言或調整其程式碼。這種靈活性消除了其他解決方案中經常存在的技術障礙，這些解決方案通常需要專門的程式語言和更複雜的流程。

How is Scroll’s Architecture Composed?

Scroll的架構是如何組成的？

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 的架構由多個相互關聯的元素組成，使其能夠充當以太坊上的 zk-rollup 解決方案。下面，我們將詳細探討每個組件：

* 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 是基於 zkEVM 技術構建的，這使其與以太坊虛擬機器（EVM）完全相容。這使得開發人員可以使用任何 EVM 相容語言在 Scroll 上部署智慧合約，而無需修改程式碼。

* 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 將大量鏈下交易捆綁在一起，然後將其提交到以太坊主網路。該技術有助於減少主鏈上的汽油費和擁堵，同時實現更快的交易處理時間。

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

* 測試網：Scroll 目前運作一個測試網，使用者可以直接與平台互動並參與測試各種去中心化應用程式 (dApp) 和專案。

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

* Scroll Token (SCR)：角色、實用性與相關性

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代幣發揮著至關重要的作用，不僅作為網路參與的激勵工具，而且作為確保高效和去中心化運作的機制。讓我們探討一下這種加密貨幣如何整合到網路架構中以及它為用戶和開發人員提供的優勢。

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.

它主要用於兩個目的：參與網路的去中心化治理以及作為生態系統內支付交易費用的媒介。

Its Impact on the Ethereum Ecosystem

它對以太坊生態系的影響

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.

在以太坊生態系統中實施 Scroll 有可能緩解網路的一些最大問題，特別是與可擴展性和高成本相關的問題。為了確保區塊鏈保持高效和可訪問性，像 SCR 這樣的第 2 層解決方案變得越來越必要。

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.

由於Scroll，開發人員現在擁有了一個可擴展平台，不僅可以改善用戶體驗，還可以創建更複雜、功能豐富的應用程序，大規模利用其更大的容量，而無需擔心主網絡擁塞的風險。

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，值得強調的是，Scroll 吸引了龐大的開發者社區，從其測試網路上已經實施的廣泛項目即可看出。這一點對於確保平台的長期可持續性和成長至關重要。
