Web3 Chain Abstraction: The Key to Simplifying User Experience

In today's world of continuous advancements in blockchain technology, Web3 still faces a significant challenge: ordinary users find it difficult to ease into it. The current Web3 environment requires users to deal with various wallets, signing operations, cross-chain bridges, and complex address formats, which starkly contrasts with the everyday use of Web2 applications.

To truly bring blockchain technology into the mainstream, we need to hide the underlying complexities so that users can complete operations as naturally as they would with Web2 applications, without having to worry about the type of underlying chain, the implementation of cross-chain transactions, or security measures. This is the core goal of Chain Abstraction – to break the fragmentation of multiple chains and make user interactions with blockchains simple, unified, and seamless.

The Essence of Chain Abstraction

The core concept of chain abstraction is to allow users and developers to freely use cross-chain applications and assets without needing to understand or directly interact with the underlying blockchain structure. Ideally, users should be able to easily perform various operations, such as swapping, staking, lending, or purchasing NFTs, without having to consider which chain they are using or which protocols are involved.

This concept differs from account abstraction. Chain abstraction focuses on seamless handling of cross-chain interactions, while account abstraction emphasizes making transaction authorization more flexible, such as allowing smart contracts or agents to automatically execute transactions. These two technologies can be used together to further enhance the user experience.

The Value of Chain Abstraction

1. Enhance User Experience: By integrating complex cross-chain operations in the background, we provide users with a unified and smooth interaction interface, greatly simplifying the operational process.

2. Solving the Problem of Blockchain Fragmentation: With the emergence of more public chains, Rollups, and application chains, chain abstraction can connect these "information islands," allowing assets and operations to flow smoothly across different chains.

3. Optimize Liquidity Management: Chain abstraction can bridge the gaps between chains, allowing for the free flow of assets, thereby reducing the issue of fragmented liquidity. This not only benefits users but also helps developers avoid the disconnection of users and liquidity caused by multi-chain deployment.

Technical Implementation and Challenges

The key technologies for achieving chain abstraction include cross-chain communication protocols, various types of cross-chain bridges, cross-chain operation coordination tools, and account abstraction schemes that support flexible authorization models. Some blockchain projects are actively exploring this area, promoting the development of chain abstraction through different technological paths.

However, the implementation of chain abstraction still faces many challenges:

• Differences in execution environments across chains
• The duration of transaction finality time (especially on certain public chains)
• High Gas fees
• Insufficient interoperability between certain ecosystems
• The technical threshold for building cross-chain intent and orchestration systems is relatively high.

Future Outlook

The ultimate goal of chain abstraction is to provide users with a seamless experience comparable to Web2. Ideally, users should be able to easily perform various Web3 operations without being overly concerned with the underlying technical details. Although there are still many challenges at present, the future of multi-chain interoperability is gradually shifting from a vision to reality with the continuous improvement of infrastructure and ongoing technological innovation.

In this process, different projects and ecosystems are exploring their own solutions. Through continuous technological innovation and optimization of user experience, Web3 is expected to achieve true popularity in the future, bringing the convenience and value of blockchain technology to a wider user base.
