Inter-Blockchain Communication Protocol (IBC): Unleashing Interoperability in the Cryptosphere

区块链间通信协议（IBC）：释放加密领域的互操作性

Introduction

介绍

Before the advent of blockchain bridges, the blockchain landscape consisted of isolated networks, inhibiting direct communication and limiting interoperability. The crypto industry's relentless pursuit of innovation has given rise to bridges that connect different blockchains, enabling the seamless exchange of data and assets. However, bridges are not the sole solution to the interoperability challenge. The Inter-Blockchain Communication Protocol (IBC) has emerged as a groundbreaking framework that establishes a standardized protocol for achieving interoperability, facilitating direct cross-chain communication and fostering a more connected blockchain ecosystem.

在区块链桥出现之前，区块链景观由孤立的网络组成，抑制了直接通信并限制了互操作性。加密行业对创新的不懈追求催生了连接不同区块链的桥梁，实现了数据和资产的无缝交换。然而，网桥并不是解决互操作性挑战的唯一解决方案。区块链间通信协议（IBC）已成为一个突破性的框架，它建立了一个标准化协议，以实现互操作性、促进直接跨链通信并培育更加互联的区块链生态系统。

What is the IBC Protocol?

什么是 IBC 协议？

The IBC protocol is an open-source framework that serves as a conduit for message relay between disparate distributed ledgers, effectively connecting independent blockchains. It facilitates the secure exchange of data and communication between blockchains, or "zones," allowing for the seamless transfer of information, asset swaps, and interactions. Introduced by Cosmos Network in 2019, IBC is a pivotal solution to the challenge of isolated blockchains, enabling secure asset and data exchange, and contributing to a more accessible and scalable blockchain ecosystem.

IBC 协议是一个开源框架，可作为不同分布式账本之间消息中继的渠道，有效连接独立的区块链。它促进了区块链或“区域”之间的安全数据交换和通信，从而实现信息、资产交换和交互的无缝传输。 IBC 由 Cosmos Network 于 2019 年推出，是应对孤立区块链挑战的关键解决方案，可实现安全的资产和数据交换，并为更易于访问和扩展的区块链生态系统做出贡献。

Technical Architecture of IBC

IBC技术架构

The Inter-Blockchain Communication (IBC) protocol comprises two distinct layers: the Transport Layer (TAO) and the Application Layer.

区块链间通信（IBC）协议包括两个不同的层：传输层（TAO）和应用层。

Transport Layer (TAO):

传输层（TAO）：

The TAO constitutes the foundational layer of the IBC protocol, responsible for establishing secure connections and authenticating data packets between blockchains. It consists of several key components:

TAO构成了IBC协议的基础层，负责在区块链之间建立安全连接和验证数据包。它由几个关键组件组成：

• IBC Light Clients: Nodes that validate cross-chain transactions and store blockchain information, ensuring the validity of exchanged data.
• IBC Relayers: Entities that monitor updates on IBC Light Clients and relay messages between blockchains, ensuring a smooth flow of information.
• IBC Connections: Establish connections between IBC Light Clients on different chains, verifying the identity of counterparty chains and enabling cross-chain verifications.
• IBC Channels: Facilitate communication between applications or modules on IBC-compatible chains, enabling the transfer of data packets.

Application Layer:

IBC 轻客户端：验证跨链交易并存储区块链信息的节点，确保交换数据的有效性。IBC 中继器：监控 IBC 轻客户端上的更新并在区块链之间中继消息的实体，确保信息的顺畅流动。IBC 连接：在不同链上的IBC轻客户端之间建立连接，验证对方链的身份并实现跨链验证。IBC通道：促进IBC兼容链上的应用程序或模块之间的通信，实现数据包的传输。应用层：

Built on top of the TAO, the Application Layer specifies the manner in which data packets must be bundled and interpreted by the chains involved in cross-chain communication. It enables diverse chains to be compatible, facilitating trustless communication, asset exchange, and interaction.

应用层建立在 TAO 之上，指定跨链通信所涉及的链必须捆绑和解释数据包的方式。它使不同的链能够兼容，促进去信任的通信、资产交换和交互。

Key Features of IBC Protocol

IBC 协议的主要特点

The IBC protocol employs dedicated channels and intelligent contract modules to establish secure and trustworthy communication between interconnected blockchains.

IBC协议采用专用通道和智能合约模块在互连的区块链之间建立安全可信的通信。

• Interoperability Without Direct Communication: A critical feature of the IBC protocol is its ability to facilitate interoperability among blockchains without requiring direct communication. Blockchains can connect effortlessly by exchanging information packets via designated channels that employ intelligent contract modules and a light client to validate the authenticity of the received state. This allows blockchains to move value or data effortlessly, irrespective of protocol or consensus procedures.
• Trustless and Permissionless: IBC operates on a trustless and permissionless basis, allowing anyone to serve as a relayer. The blockchains involved do not need to place trust in the individuals transmitting the data. This configuration is crucial for achieving blockchain sovereignty without isolating blockchains, an essential goal of the Cosmos ecosystem.
• Secure and Validated: IBC maintains the validity of the information transmitted between blockchains by integrating innovative contract modules with light client verification, eliminating the need for direct connection. This minimizes the requirement for blind trust between parties and enhances the overall security of the ecosystem. IBC maintains the security and integrity of cross-chain transactions by utilizing cryptographic primitives and consensus methods such as Tendermint.
• Blockchain-Specific Security: The IBC protocol maintains security and validity by leveraging cryptographic techniques and consensus algorithms unique to each participating blockchain. Data privacy and integrity are protected during transmission.

Mechanism of IBC Protocol Operation

无需直接通信的互操作性：IBC 协议的一个关键特性是它能够促进区块链之间的互操作性，而无需直接通信。区块链可以通过指定通道交换信息包来轻松连接，这些通道采用智能合约模块和轻客户端来验证接收状态的真实性。这使得区块链可以毫不费力地移动价值或数据，而不管协议或共识程序如何。 无需信任和无需许可：IBC 在无需信任和无需许可的基础上运行，允许任何人充当中继者。所涉及的区块链不需要信任传输数据的个人。这种配置对于在不隔离区块链的情况下实现区块链主权至关重要，这是 Cosmos 生态系统的基本目标。 安全和验证：IBC 通过将创新合约模块与轻客户端验证集成，无需直接连接，从而保持区块链之间传输信息的有效性。这最大限度地减少了各方之间盲目信任的要求，并增强了生态系统的整体安全性。 IBC 通过利用加密原语和共识方法（例如 Tendermint）来维护跨链交易的安全性和完整性。区块链特定安全性：IBC 协议通过利用每个参与区块链特有的加密技术和共识算法来维护安全性和有效性。数据传输过程中的隐私性和完整性受到保护。IBC协议运行机制

The Inter-Blockchain Communication (IBC) protocol facilitates seamless communication between different blockchains, operating through two layers: the TAO layer (Transport, Authentication, and Ordering) and the APP layer (Application).

区块链间通信（IBC）协议促进不同区块链之间的无缝通信，通过两个层进行操作：TAO 层（传输、身份验证和排序）和 APP 层（应用程序）。

• TAO Layer: Secure connections are established, and data is verified between blockchains in the TAO layer, which serves as the foundation for communication.
• APP Layer: Defines how data is packaged and interpreted by different blockchains.

Key components of the IBC protocol include hubs and zones, packet transactions, and smart contracts.

TAO 层：在 TAO 层中建立安全连接，并在区块链之间验证数据，作为通信的基础。APP 层：定义不同区块链如何打包和解释数据。IBC 协议的关键组件包括集线器和区域、数据包交易和智能合约。

• Hubs and Zones: Hubs function as central routers, facilitating communication between zones representing individual blockchains.
• Packet Transactions: Contain sender, recipient, and transaction data, enabling efficient communication between zones.
• Smart Contracts: Implemented as IBC/TAO modules on each blockchain, facilitate the orderly transfer of data packets between blockchains.

Data transfer via IBC involves a cross-chain transaction, where the packet traverses from the source zone to a hub and the destination zone. Upon processing, the destination blockchain responds, following the same path back. The TAO layer manages infrastructure and security, while the APP layer determines data packaging and interpretation.

集线器和区域：集线器充当中央路由器，促进代表各个区块链的区域之间的通信。数据包交易：包含发送者、接收者和交易数据，实现区域之间的高效通信。智能合约：在每个区块链上作为 IBC/TAO 模块实施，促进区块链之间数据包的有序传输。通过 IBC 的数据传输涉及跨链交易，其中数据包从源区域穿越到集线器和目标区域。处理后，目标区块链会按照相同的路径返回进行响应。 TAO层管理基础设施和安全性，而APP层决定数据打包和解释。

Eligible Blockchains for IBC Implementation

符合 IBC 实施条件的区块链

The Inter-Blockchain Communication (IBC) protocol is designed to be implemented by any blockchain that meets specific requirements. These requirements ensure the blockchain can achieve low-cost, verifiable finality and support vector commitments.

区块链间通信（IBC）协议旨在由满足特定要求的任何区块链实施。这些要求确保区块链能够实现低成本、可验证的最终性并支持向量承诺。

• Low-Cost, Verifiable Finality: Finality refers to transactions or blocks being irreversible and permanently confirmed. For a blockchain to be IBC-compatible, it must achieve finality at low costs.
• Vector Commitment Support: In blockchains, state machines transition from one state to another based on inputs, such as user transactions. Blockchains must support vector commitments, enabling them to commit multiple values simultaneously using cryptographic techniques. Vector commitments enable efficient verification by allowing users to prove the presence of a specific set of transactions without revealing the entire dataset. This scalability and simplicity in verification are crucial for implementing the IBC protocol.

By meeting these requirements, blockchains can support IBC Light Clients in verifying transactions and proofs of verification of counterparty blockchains. This ensures interoperability and seamless communication between different blockchains in the ecosystem.

低成本、可验证的最终性：最终性是指交易或区块不可逆转且永久确认。对于与 IBC 兼容的区块链，它必须以低成本实现最终确定性。向量承诺支持：在区块链中，状态机根据输入（例如用户交易）从一种状态转换到另一种状态。区块链必须支持向量承诺，使它们能够使用加密技术同时提交多个值。矢量承诺允许用户证明一组特定交易的存在，而无需透露整个数据集，从而实现有效的验证。这种验证的可扩展性和简单性对于实现 IBC 协议至关重要。通过满足这些要求，区块链可以支持 IBC 轻客户端验证交易和交易对手区块链的验证证明。这确保了生态系统中不同区块链之间的互操作性和无缝通信。
