A New Chapter in Full-Chain Interoperability: The Innovative Journey of ZetaChain

In the current flourishing multi-chain ecosystem, numerous public chains are emerging, but this is accompanied by challenges such as the retreat of liquidity and funding shortages. Some public chains rely on cross-chain bridges to introduce assets; however, once a cross-chain bridge experiences a security vulnerability, the entire ecosystem may suffer a devastating blow, which undoubtedly serves as a wake-up call for the entire industry.

It is against this backdrop that ZetaChain was born. As a forward-looking full-chain interoperability platform, it is dedicated to addressing the fragmentation and limitations within the existing blockchain ecosystem. By seamlessly connecting assets and data across different blockchain networks, ZetaChain opens up new possibilities for the development and operation of decentralized applications.

The core team of ZetaChain brings together seasoned experts from well-known companies in the industry. These team members translate their rich experience in the Web3 field and deep insights into market demands into ZetaChain's core technology and strategic direction. Their shared vision is to create a blockchain that can serve as a passport to the Web3 world, thereby simplifying and accelerating the development of decentralized applications and enhancing user experience.

In the development of blockchain, interoperability has always been a core issue. ZetaChain not only provides innovative solutions technically but also sets new standards in implementation. Through its unique multi-party computation system and threshold signature scheme, ZetaChain achieves interoperability with traditional non-smart contract chains like Bitcoin and Dogecoin.

ZetaChain is committed to becoming a true cross-chain interoperability and asset transfer platform by providing full-chain accounts. Below is our in-depth exploration of the ZetaChain project, revealing how this project brings transformation to the decentralized ecosystem in the Web3 era.

Core Contributions of ZetaChain

Core contributors of ZetaChain recognized the necessity of building ZetaChain and the concept of the "only blockchain needed" after participating in multiple Web3 projects. Currently, developers of decentralized applications face complexity issues when building products for multiple chains, and this step is essential for seizing opportunities in the Web3 market. They also often need to consider how to ensure that the product can adapt to future technological developments and changes. ZetaChain not only addresses these issues but also simplifies the user experience. These challenges stem directly from the team's previous work experience in the crypto industry.

Achieving Universal Interoperability

ZetaChain adopts a multi-party computation system, where each signature validator holds a portion of the private key. On each connected chain, there is an account derived from this private key. Using a Threshold Signature Scheme (TSS), validators can sign transactions from this TSS account. Since the TSS account is a regular external account, it does not need to execute smart contract logic on the connected chain, which allows interoperability even for chains like Bitcoin that do not support smart contracts.

Tokens transferred to the TSS address on the connected chain will be converted into ZRC-20 wrapped tokens on ZetaChain. Withdrawing ZRC-20 from ZetaChain to the connected chain will trigger the transfer of tokens from the TSS address to the recipient.

Advantages of Omnichain Technology

Omnichain contracts allow DApp developers to create DApps that can accept inputs from any connected chain and trigger outputs to any connected chain. The advantage of Omnichain over cross-chain messaging lies in its simpler architecture, as it does not require the deployment and management of numerous contracts across different chains. Omnichain also enables interoperability on non-smart contract chains, effectively providing users of non-smart contract chains with a method to build Omnichain smart contracts.

Features of the ZetaEVM Module

ZetaChain uses the Ethermint Cosmos SDK module to provide full EVM compatibility. In terms of single-chain performance and security, ZetaChain is comparable to other Cosmos blockchains that use the same EVM module. To achieve omnichain functionality, the ZetaChain team developed a custom Cosmos SDK module, EVM contracts, and an off-chain observer called zetaclient, which together enhance the omnichain capabilities of regular EVM contracts.

Implementation of Multi-Chain Functionality

ZetaChain does not require a third-party cross-chain bridge, as its own mechanism provides the functionality for cross-chain messaging and token transfers. ZetaChain focuses on moving native, unwrapped assets between different chains, allowing users to receive native tokens on the target chain. This approach enhances the security of the entire process, as once the cross-chain transaction is completed, users no longer rely on ZetaChain to return assets to the original chain.

Although there are indeed ZRC-20 wrapped tokens representing assets transferred from connected chains on ZetaChain, these wrapped tokens only exist during the transaction process for cross-chain operations, and end users do not interact with them directly.

Advantages of Technology Selection

ZetaChain utilizes the Comet BFT consensus engine, providing instant transaction finality, high throughput, and reliability. The Cosmos SDK offers developers a range of ready-made building blocks, such as staking modules, governance modules, and EVM-compatible layers. The modularity of the Cosmos SDK allows ZetaChain's protocol team to develop modules that realize cross-chain messaging and support for fungible token Omnichain contracts.

User and Developer Attraction Strategy

ZetaChain believes that for developers looking to build Web3 applications and services, choosing which chain to launch their product on is very challenging, and the process of expanding to other chains is equally difficult. The vision of building a single chain that can access all other chains resonates within the global developer community. ZetaChain actively builds relationships with developers by participating in various events, organizing hackathons, and publishing development documentation to help them build applications. At the same time, ZetaChain fosters close relationships with developers, proactively seeking their feedback and suggestions. Additionally, an ecosystem grant program has been established to support promising developers in making Omnichain-related innovations on ZetaChain.

Key Points of Ecological Planning

ZetaChain's initial focus was on DeFi projects, as there was a strong demand from users and developers in this field. Despite currently being in a bear market environment, the DeFi sector still maintains a strong momentum for development, so it is reasonable to have a strong demand for multi-chain expansion and growth. At the same time, ZetaChain also collaborates widely with developers and DApps across various industries, including gaming, NFTs, social finance, and payments.

Asia Community Strategy

Asia remains the core area of Web3. ZetaChain is proud of the community established in Asia and their enthusiasm for the platform. By collaborating with local ambassadors and communities and regularly participating in key events, ZetaChain ensures that it stays connected and responsive to the needs of developers and local communities.

Mainnet Launch Plan

Regarding the specific launch date of the mainnet, ZetaChain is currently unable to provide detailed information. Users can follow and subscribe to ZetaChain's social media accounts to ensure they stay updated on the latest news and announcements.
