WASM Virtual Machine

Definition ∞ A WASM Virtual Machine is a runtime environment that executes WebAssembly code, often within a blockchain context. This virtual machine provides a secure and efficient sandbox for running smart contracts and decentralized application logic. It supports various programming languages, broadening developer options for blockchain development.
Context ∞ The discussion around WASM Virtual Machines often highlights their advantages in terms of execution speed and language flexibility compared to older blockchain virtual machines. Debates frequently address the security audits and formal verification methods needed to ensure the integrity of WASM-based smart contracts. Observing its adoption in new blockchain protocols and updates to existing ones will demonstrate its impact on the scalability and functionality of decentralized systems.
