Analysis of the Advantages of Move VM

Move VM is a smart contract virtual machine developed by former Facebook (now Meta) for the Diem (formerly Libra) blockchain project. Compared to traditional EVM, Move VM has significant advantages in performance, security, and flexibility, gradually becoming an important choice for the next generation of blockchain systems.

Firstly, the design of Move VM in terms of security is highly innovative. The Move language itself has a powerful asset security model built-in, where all resource types (such as tokens) are moved (Move) once instead of being copied, preventing common errors such as asset loss and double spending. This concept of “resources as code” fundamentally avoids asset security vulnerabilities caused by developers' inadvertent mistakes, greatly enhancing the reliability of contracts.

Secondly, Move VM supports parallel execution, which improves overall throughput. In traditional EVM, transactions must be executed serially due to the risk of state conflicts, while Move VM can analyze the dependencies between transactions in advance through clearer resource access declarations, allowing non-conflicting transactions to be processed in parallel. This mechanism significantly increases TPS (transactions per second) both theoretically and practically, far exceeding standard EVM performance.

Thirdly, flexibility and modularity are important advantages of Move VM. Move supports modular programming, allowing smart contracts to be flexibly combined, upgraded, and operate independently, resulting in a cleaner and more controllable contract design compared to EVM. At the same time, the Move language has designed capabilities and permission control mechanisms, allowing developers to manage the operational permissions of different roles over resources with fine granularity, increasing the freedom and security of DApp development.

Additionally, Move VM is naturally suited for financial applications and complex asset management. Its underlying resource management model aligns closely with the logic of financial assets (such as non-replicable, non-lost, and transferable by authorization), therefore performing exceptionally well in scenarios such as developing stablecoins, DEX, asset custody, and DeFi.

In summary, Move VM has become a highly competitive next-generation virtual machine in current blockchain technology by enhancing security, supporting parallel processing, optimizing resource control, and improving flexibility. As chains like Aptos and Sui adopt Move VM, it is expected to become an important force surpassing EVM in the future.
