Intro to Sui Move
Welcome to the tutorial! The Sui Move is a variant of the Move programming language.
Move is a programming language that was developed by Facebook specifically for use on the Libra blockchain. It is a relatively new language that was first introduced in 2019, so there is still a lot to learn about it. Here are some key points to help build intuition about Move:
- Move is designed for safety: One of the main goals of Move is to ensure the safety of transactions on the Libra blockchain. Move accomplishes this through a combination of features like static typing, resource ownership, and automated checks for correct usage.
- Move is a high-level language: Despite being designed for safety, Move is a high-level programming language that is easy to use and read. It features a syntax similar to Rust or Swift, with support for modules, functions, and types.
- Move is focused on smart contracts: Move is primarily designed for developing smart contracts on the Libra blockchain. This means that it includes features like a native asset management system, support for custom data structures, and a built-in interpreter for running contracts.
- Move has a unique ownership model: Move uses a unique ownership model that allows developers to track the ownership and movement of resources within their contracts. This model helps prevent errors like double-spending and ensures that resources are always used correctly.
- Move is still evolving: Because Move is a relatively new language, it is still evolving rapidly. Facebook and the broader Move community are actively working to improve the language, add new features, and make it easier to use.
