The SpaceVM isn’t your average virtual machine. It’s the robust core of MultiversX’s blockchain, designed to give developers a fast, secure, and WASM-compatible environment for creating smart contracts. It supports WebAssembly (WASM), allowing developers to write contracts in Rust—a language known for both efficiency and readability. Here’s a look at how SpaceVM is optimized for blockchain demands.

Highlights of SpaceVM

• Stateless Design: SpaceVM holds changes in memory until a contract finishes, ensuring only fully completed contracts affect the blockchain state. This keeps things clean and avoids half-done updates.
• High-Speed Execution: SpaceVM leverages an enhanced Wasmer engine for near-native speed, with features like precise metering and preemptive control, making sure contracts run efficiently and can be stopped if needed.
• Adaptive Sharding: SpaceVM automatically switches between synchronous and asynchronous calls depending on whether contracts are in the same shard, allowing seamless execution across MultiversX’s sharded network.

Why SpaceVM Matters

From fast processing to sharding adaptability, SpaceVM is tailored for the demands of blockchain, letting developers create secure, high-performance applications with ease on MultiversX.
