What is Intent-Centric Blockchain Design?

As blockchain technology evolves, the concept of "intent" proposed by Paradigm has garnered widespread attention. Following this, projects like dappOS have also adopted this concept. Renowned venture capital firms such as Sequoia Capital and Binance have entered this field.

Definition of Intent

In the Web3 world, users often face complex tasks such as choosing platforms, fetching the best prices, switching blockchains, and ensuring signature security, making operations cumbersome and prone to errors. The intent design concept was introduced to address these issues. "Intent" emphasizes the central role of user intent. By using smart contracts or protocols, user intents are encoded into executable instructions, enabling automated operations and interactions.

Simply put, intent is like a chef in a restaurant. Users only need to express their needs—order a dish—and then enjoy the food without worrying about the cooking process details. Similarly, in the blockchain world, users only need to state the desired outcome, and the system will automatically execute the corresponding steps to achieve it. For example, a user only needs to say, "I want to send 50 USDC to Lao Wang," without concerning themselves with the technical operational details.

Limitations of Traditional Transaction Models

- Opaque Transaction Process: Transaction outcomes are influenced by network congestion, miner behavior, blockchain state, and other factors, making them susceptible to front-running and Maximal Extractable Value (MEV) attacks.

- Complex Cross-Network Transactions: Coordinating across multiple domains, protocols, and applications increases operational difficulty.

- Signature Control Risks: Users grant extensive permissions to smart contracts and decentralized applications through signatures, increasing risk.

- Poor Readability: Users must understand low-level transaction details, making operations complex.

- Lack of Flexibility: It's challenging to achieve cross-domain combinations and privacy features.

- Centralization Risks: Miners and validators can reorder and censor transactions to extract value, increasing MEV attack risk.

Advantages of Intent-Based Transactions

- Increased User Control: Users can set constraints rather than relinquishing all permissions.

- Personalization: Users can specify privacy, atomicity, counterparty, and fee parameters according to their needs.

- Flexible Cross-Domain Combinations: Intents can specify outcomes across applications, protocols, and blockchains, maximizing transaction possibilities.

- Mitigation of MEV Attacks: Encryption and programmability hinder solvers from extracting value.

- Optimized Transaction Outcomes: Professional solvers optimize intent realization, improving transaction efficiency.

- High Readability: Intents align better with user mental models, making operations more intuitive.

Intent-centric blockchain design simplifies operational processes, increases transparency and flexibility, and offers users a more intuitive and efficient experience. This design philosophy has the potential to revolutionize blockchain and Web3 interaction models, driving further adoption and development.
