Exclusive Interview with the Founder of Move Language: Why Sui Move is Suitable for Building Web3 Products?

Recently, we spoke with Sam Blackshear, the Chief Technology Officer of Mysten Labs and the founder of the Move programming language, to discuss his reasons for developing the new smart contract programming language Sui Move, Sui's scalability, and the advantages of decentralized technology for developers.

The following are the main points of the interview:

The Essence of Programming Languages and the Birth of Move

Programming languages are tools for clear, safe, efficient, and explicit interaction with computers. Unlike natural languages, programming languages require precisely defined semantics. When writing programs, developers need to have a clear understanding of the program's behavior.

Move originated from Facebook's Libra project. After studying existing smart contracts, it was found that they cannot meet developers' needs in many cases. Smart contracts primarily define asset types and their transfer rules, as well as check access control policies. Move aims to provide a good abstraction for these fundamental functions, enabling programmers to write code safely and efficiently.

Features of Sui Move and its Applications in Web3

Sui Move is a variant of Move, which changes due to the following factors:

1. Removed some restrictions from the original Libra project, allowing assets to circulate more freely.

2. Introduced an object-oriented data model, simplifying the asset handling process.

3. Programmable transaction blocks have been implemented, allowing multiple operations to be executed in a single transaction.

These features make Sui Move very suitable for building Web3 products, providing greater flexibility and efficiency.

Development Experience of Sui Move

Many developers have reported that the development experience on Sui Move is more efficient and secure. For example, a DeFi project team stated that they completed what would have taken eight months of Solidity development work in just two months using Sui Move, and they are more confident in the project's security.

Sui's Scalability Design

The goal of Sui is to achieve horizontal scalability, meaning increasing throughput by adding hardware without being limited by an upper bound. This design allows Sui to continuously scale with user growth while maintaining low latency.

The object-oriented data model is key to achieving this goal. The global state is organized into a mapping from object IDs to objects, making this key-value storage easier to scale.

The Potential of Decentralized Technology

Blockchain and cryptocurrency are essentially a frictionless technology. They can eliminate barriers in financial transactions, application development, and information setup, reducing reliance on third parties.

This technology can enhance interoperability between applications, allowing assets, data, and functionalities to flow more freely across different applications.

The Future Development of Sui Move

The future development direction of Sui Move includes:

1. Improve the package update and extension capabilities based on developer feedback.

2. Introduce new features, such as enumeration types.

3. Improve the connection experience between Move and frontend code.

4. Committed to increasing the proportion of Move code in applications to enhance security.

5. Simplify the development process of Move programs to make it more user-friendly for various developers.
