Chain Abstraction: A Paradigm Shift in Blockchain Architecture

Chain abstraction is an important stage in the development of Blockchain technology, representing the evolution from monolithic chains to modular public chains, and now to chain abstraction. This concept is not merely a simple combination of liquidity pool bridges, account abstraction, and social account logins, but a comprehensive technological innovation.

In computer engineering, abstraction is a common construction method aimed at simplifying complex systems into more understandable and manageable forms. The core goal of chain abstraction is to simplify Blockchain operations, making them more user-friendly. This transformation occurs not only at the user experience level but also involves infrastructure and middleware.

The cross-chain bridge field is experiencing significant innovation. In addition to traditional messaging and liquidity pool models, emerging Solver Network and Filler Network models are on the rise, which separate inter-chain messaging from liquidity provision. Some platforms are adopting new standards to standardize cross-chain order structures, while others are introducing AI agents as automated arbitrageurs to achieve the intent of instant settlement bridging.

In the upcoming Pectra upgrade of Ethereum, a new proposal will allow regular addresses to point to smart contract addresses, granting them programmability. This means that users will be able to utilize more advanced features such as multi-signature, custom batch transactions, one-click loop staking, or lending.

In the wallet space, some innovative solutions allow users to create smart contract wallets with the same address on multiple EVM-compatible chains at once, greatly simplifying the complexity of managing multi-chain wallets.

Overall, chain abstraction represents a comprehensive paradigm shift. These changes may not be initially perceived by the public, but over time, they will gradually reshape the architecture of Blockchain and the industry landscape of Web3. This transition is not smooth and uniform, but follows the patterns of "disruptive innovation" and "exponential growth," reflecting the non-linear characteristics of technological development.
