Let's explore how Sui Move is different from Diem's Move

Sui Move vs. Core Move: Exploring the Evolution of Blockchain Programming

Sui Move is a powerful adaptation of the core Move language, specifically designed to address the needs and limitations of the ever-growing blockchain ecosystem. While Sui Move maintains the core principles of Move, it introduces several key differences that significantly enhance the programming model, scalability, and user experience for developers.

Object-centric global storage: Unlike Core Move, which relies on global storage for resources and modules, Sui Move eliminates the need for global storage operations. Instead, it leverages Sui's own object-centric storage system, significantly improving the efficiency and scalability of storage-heavy applications such as marketplaces and social apps.
Addresses as Object IDs: In Sui Move, the address type is used to represent Object IDs rather than user accounts. This simplification streamlines the programming model and enhances the security of the system.
Objects with key abilities and globally unique IDs: Sui Move distinguishes between internal objects and those stored in Sui storage by leveraging the key ability in Move. This allows for secure serialization and deserialization of objects at the Move-Sui boundary.
Module initializers: Sui Move introduces a special initializer function for modules that are executed during publication. This allows for the pre-initialization of module-specific data, enhancing the overall programming experience.
Entry points accepting object references as input: Unlike Core Move, Sui Move enables entry functions to accept object references as input, offering a more seamless integration between Sui and Move.

In conclusion, Sui Move builds upon the foundation of Core Move while addressing the limitations and challenges faced by blockchain developers. This innovative adaptation of Move offers enhanced throughput, reduced finality delays, and a more user-friendly programming experience.
