📝 Hi, I’m 𝟏𝟎, and this is the popular science series of #BlockchainDevelopmentHistory. This issue’s content: cross-chain interoperability.

Cross-chain interoperability refers to the ability to achieve seamless communication and data exchange between different blockchain networks. This feature promotes the free flow of information and value and improves the overall connectivity and integration of blockchain applications.

1. What is cross-chain interoperability?

Cross-chain interoperability sounds complicated, but it is actually the ability to freely exchange data and assets between different chains without the need for intermediaries or centralized exchanges. In simple terms, it allows smart contracts on different platforms to communicate with each other without the need to actually transfer tokens. Through standardized protocols, this technology enables seamless integration of assets and services regardless of the underlying technology. Cross-chain interoperability is critical for applications such as DeFi, NFT markets, and SocialFi, helping to build a more connected and efficient blockchain world.

2. Why is cross-chain interoperability so important?

Today’s blockchains are a bit like the early Internet: isolated and incompatible. This means your assets and data are trapped on isolated islands and cannot be easily transferred across chains. It is very troublesome for users to transfer money between different chains, requiring a complex bridging process, which is not only time-consuming but also increases security risks. Developers are also troubled because the applications on each chain (such as DEX) are independent and cannot interact with each other. To solve these problems, we need similar technological breakthroughs, just like the PageRank algorithm changed the Internet, to achieve seamless connection between blockchains.

3. Different types of cross-chain interoperability solutions

As developers continue to introduce new solutions, cross-chain interoperability is becoming stronger and stronger, making it easier to transfer data and assets between different blockchains. It's like allowing previously unconnected systems to communicate freely. It not only breaks the isolation of blockchains, but also opens new doors for the development of easier-to-use and more interconnected blockchain applications. There are different ways to improve cross-chain interoperability. Here are some solutions to see how it is achieved.

Wormhole

Wormhole is a universal cross-chain bridge protocol that allows tokens and messages to be transferred between different blockchains (such as Ethereum, Solana, Avalanche). Through verification by "network guardians", Wormhole ensures that these transfers are safe and reliable. Developers can use this tool to create cross-chain decentralized applications (xDapp), thereby promoting a closer interconnection of the blockchain ecosystem.

Axelar

Axelar is a cross-chain tool that allows different blockchains to communicate and transfer data with each other. Developers can use Axelar to build applications that run on multiple blockchains, and all cross-chain communications will be secured through delegated proof of stake (dPoS). For example, Axelar's application Satellite can connect BUSD on Ethereum to Cosmos, and the two systems can communicate with each other. This solution makes the development of cross-chain dApps simpler and more efficient, and improves the functionality of the entire blockchain ecosystem.

Chain link

Chainlink is developing a tool called the Cross-Chain Interoperability Protocol (CCIP). Simply put, it allows messages and tokens to be transferred between different blockchains. The goal of CCIP is to connect hundreds of blockchains with a unified interface to reduce the complexity of developing cross-chain applications. It is itself a very famous decentralized oracle network (DON), providing secure and reliable data support for various blockchain applications.

LayerZero

LayerZero is a full-chain interoperability protocol that focuses on lightweight cross-chain messaging and provides secure, trustless communication. Its ultra-light node (ULN) is like a smart contract that is only activated when necessary to help improve efficiency. Through LayerZero's interface, ULN can communicate with oracles and relayers. This design makes cross-chain communication smoother and developers can more easily create decentralized applications that run on multiple blockchains.

IV. Conclusion

Cross-chain interoperability solutions can significantly improve the efficiency of blockchain networks, significantly improving efficiency and user experience by enabling seamless communication and data transmission between different networks. Achieving this interoperability requires highly stable and secure technical solutions, and the best solutions are still being explored.

Interoperability is not only a technological breakthrough, but also the key to promoting innovation in various fields. However, achieving this goal requires overcoming technical difficulties, security risks and governance issues, and relies on extensive cooperation within the industry.

The contributions of companies like Blaize in the field of cross-chain interoperability are critical, helping to solve complex challenges and paving the way for a more connected and innovative blockchain future. In short, cross-chain interoperability is the cornerstone of building an open and efficient digital world.
