Layer 0：支撐區塊鏈生態系統的無形力量

區塊鏈第 1 層和第 2 層相當知名，但還有一個更基礎的層支援整個區塊鏈生態系統。 Layer 0 是使不同區塊鏈網路能夠無縫通訊和協同工作的基礎。

Blockchain technology has introduced a layered architecture to address the increasing complexity and diverse requirements of decentralized networks. At the foundation of this architecture lies Layer 0, a crucial yet often overlooked layer that provides the essential infrastructure for blockchain interoperability and scalability.

區塊鏈技術引入了分層架構來解決去中心化網路日益增加的複雜性和多樣化的需求。該架構的基礎是第 0 層，這是一個至關重要但經常被忽視的層，它為區塊鏈互通性和可擴展性提供了必要的基礎設施。

In this article, we will delve into the concept of Layer 0 in blockchain, exploring its components, distinguishing it from other blockchain layers, and highlighting some real-world examples. By understanding Layer 0's role, developers and users can gain valuable insights into the interconnected nature of blockchain networks.

在本文中，我們將深入研究區塊鏈中第 0 層的概念，探索其組成部分，將其與其他區塊鏈層區分開來，並重點介紹一些現實世界的範例。透過了解 Layer 0 的角色，開發人員和使用者可以獲得對區塊鏈網路互連性質的寶貴見解。

What are blockchain layers? To fully grasp the concept of Layer 0, we must first understand the broader context of blockchain layers. The blockchain ecosystem has naturally evolved into a hierarchical structure, where interconnected layers each serve specific functions and address particular challenges within the network.

什麼是區塊鏈層？要完全掌握 Layer 0 的概念，我們必須先了解區塊鏈層的更廣泛背景。區塊鏈生態系統自然地演變成一個分層結構，其中每個互連的層都服務於特定的功能並解決網路內的特定挑戰。

These layers, much like the Internet protocol suite, form a technological stack that builds upon one another, akin to Lego blocks. At the foundation, we have Layer 0, followed by Layer 1 (base layer), Layer 2 (scaling solutions), and Layer 3 (application layer). Each subsequent layer inherits properties from the layers below but also adds new functionalities and optimizations.

這些層與網際網路協定套件非常相似，形成了一個相互建構的技術堆疊，類似於樂高積木。在基礎上，我們有第 0 層，然後是第 1 層（基礎層）、第 2 層（擴展解決方案）和第 3 層（應用層）。每個後續層都繼承下面層的屬性，但也增加新的功能和最佳化。

This layered approach emerged as blockchain networks encountered challenges in scalability, security, and decentralization. Think of these layers as specialized protocols that work together to create a complete blockchain infrastructure.

隨著區塊鏈網路在可擴展性、安全性和去中心化方面遇到挑戰，這種分層方法應運而生。將這些層視為專門的協議，它們協同工作以創建完整的區塊鏈基礎設施。

Layer 1 protocols, such as Bitcoin and Ethereum, provide the fundamental consensus mechanisms and security features, while Layer 2 solutions, like Optimism, focus on scaling and transaction throughput. Layer 3 handles application-specific functions and user interfaces, making blockchain technology accessible to end-users — here you'll find familiar names like Uniswap and Decentraland.

第 1 層協定（例如比特幣和以太坊）提供基本的共識機制和安全功能，而第 2 層解決方案（例如 Optimism）則專注於擴展和交​​易吞吐量。第 3 層處理特定於應用程式的功能和用戶介面，使最終用戶可以使用區塊鏈技術 - 在這裡您會發現 Uniswap 和 Decentraland 等熟悉的名字。

What is Layer 0 in blockchain? At the heart of blockchain technology's infrastructure lies Layer 0, which comprises the core components that enable inter-blockchain communication, network connectivity, and hardware protocols.

區塊鏈中的第 0 層是什麼？區塊鏈技術基礎設施的核心是第 0 層，它由支援區塊鏈間通訊、網路連接和硬體協定的核心組件組成。

This foundational layer supports the entire blockchain ecosystem by providing essential services and protocols that facilitate seamless operation across different blockchain networks.

該基礎層透過提供促進跨不同區塊鏈網路無縫操作的基本服務和協議來支援整個區塊鏈生態系統。

Key components of Layer 0 include:

第 0 層的關鍵組件包括：

Layer 0's architecture implements fundamental Consensus Mechanisms that guarantee network synchronization and validation across multiple blockchains.

Layer 0 的架構實現了基本的共識機制，保證跨多個區塊鏈的網路同步和驗證。

The solutions of Layer 0 focus on interoperability, allowing different blockchain networks to communicate and share data efficiently. This infrastructure layer addresses critical challenges in blockchain scalability and cross-chain functionality.

Layer 0 的解決方案注重互通性，允許不同的區塊鏈網路有效地通訊和共享資料。此基礎設施層解決了區塊鏈可擴展性和跨鏈功能的關鍵挑戰。

How does it do this? It provides standardized protocols and services that higher layers can build upon.

它是如何做到這一點的？它提供了高層可以建構的標準化協定和服務。

If you're developing blockchain applications, understanding Layer 0's role becomes necessary because it directly impacts the performance, security, and interconnectivity of your blockchain solutions.

如果您正在開發區塊鏈應用程序，那麼了解第 0 層的作用就變得非常必要，因為它直接影響區塊鏈解決方案的效能、安全性和互連性。

Key features of Layer 0: While blockchain networks continue to evolve, five vital features define Layer 0's architectural framework: interoperability, scalability, customizability, decentralization, and security.

Layer 0 的主要特性：雖然區塊鏈網路不斷發展，但 Layer 0 的架構框架定義了五個重要特性：互通性、可擴展性、可自訂性、去中心化和安全性。

Layer 0 vs. Other blockchain layers To further clarify the role of Layer 0 within the blockchain ecosystem, let's compare it to other blockchain layers, highlighting their distinct functions and contributions to the overall network.

Layer 0 與其他區塊鏈層為了進一步闡明 Layer 0 在區塊鏈生態系統中的作用，讓我們將其與其他區塊鏈層進行比較，強調它們的獨特功能和對整個網路的貢獻。

Layer 0 vs. Layer 1 For an effective understanding of blockchain architecture, it's essential to distinguish between Layer 0 and Layer 1 protocols.

第 0 層與第 1 層 為了有效理解區塊鏈架構，區分第 0 層和第 1 層協定至關重要。

Layer 0 serves as the foundational infrastructure that enables multiple blockchain networks to operate and communicate, while Layer 1 represents individual blockchain protocols like Bitcoin or Ethereum.

第 0 層作為基礎設施，使多個區塊鏈網路能夠運作和通信，而第 1 層代表單獨的區塊鏈協議，例如比特幣或以太坊。

Layer 0's role in supporting Layer 1 protocols is necessary for the overall blockchain ecosystem's functionality and scalability. It allows integration of different blockchain networks. For some concrete examples, see our article comparing the leading layer 1 blockchains.

第 0 層在支援第 1 層協定方面的作用對於整個區塊鏈生態系統的功能和可擴展性是必要的。它允許整合不同的區塊鏈網路。有關一些具體範例，請參閱我們比較領先的第 1 層區塊鏈的文章。

Layer 0 vs Layer 2 Layer 0 provides the fundamental infrastructure and networking protocols that enable blockchain communication, while Layer 2 focuses on scaling solutions built on top of existing blockchains.

第 0 層與第 2 層 第 0 層提供了支援區塊鏈通訊的基本基礎設施和網路協議，而第 2 層則專注於建構在現有區塊鏈之上的擴展解決方案。

The key difference lies in their objectives. Layer 0 establishes the groundwork for blockchain interoperability and network performance, while Layer 2 solutions optimize existing specific blockchain networks.

主要區別在於他們的目標。第 0 層為區塊鏈互通性和網路效能奠定了基礎，而第 2 層解決方案則優化了現有的特定區塊鏈網路。

If this is complex to understand, here's a way to think about it: Optimism and Arbitrum are Layer 2s, and they optimize Ethereum (which is a Layer 1), but they don't optimize other Layer 1s, such as BNB or Solana.

如果這很難理解，可以考慮一下：Optimism 和 Arbitrum 是第 2 層，它們優化以太坊（第 1 層），但不會優化其他第 1 層，例如 BNB 或 Solana。

Real-world examples of Layer 0 protocols There are several prominent Layer 0 protocols in the blockchain ecosystem, which demonstrate practical implementations of cross-chain infrastructure. These protocols serve as foundational platforms that enable cross-chain communication and interoperability between different blockchain networks.

Layer 0 協議的真實範例區塊鏈生態系統中有幾個著名的 Layer 0 協議，它們展示了跨鏈基礎設施的實際實現。這些協定作為基礎平台，實現不同區塊鏈網路之間的跨鏈通訊和互通性。

The funny part is that these are often considered Layer 1s by many people in the crypto community, but these are, in fact, Layer 0s:

有趣的是，加密社群中的許多人通常將它們視為 Layer 1，但實際上它們是 Layer 0：

These Layer 0 solutions demonstrate different approaches to solving blockchain scalability and interoperability challenges.

這些第 0 層解決方案展示了解決區塊鏈可擴展性和互通性挑戰的不同方法。

Each protocol implements unique consensus mechanisms, security models, and cross-chain messaging systems to facilitate communication between various blockchain networks while maintaining their distinct characteristics and functionalities.

每個協議都實現了獨特的共識機制、安全模型和跨鏈訊息傳遞系統，以促進各種區塊鏈網路之間的通信，同時保持其獨特的特徵和功能。
