Virtual Machine

Definition ∞ A virtual machine is a software-based emulation of a physical computer system. It provides an isolated environment where programs can run as if on a dedicated hardware platform. In blockchain, virtual machines execute smart contracts and process transactions securely. They abstract the underlying hardware, ensuring consistent execution across different nodes. This abstraction is fundamental for decentralized application development.
Context ∞ Virtual machines, such as the Ethereum Virtual Machine, are central to many discussions in crypto news regarding smart contract platforms. Their design and efficiency are critical factors influencing network scalability and developer experience. New virtual machine implementations often aim to improve transaction throughput or support a wider range of programming languages.
