Ethereum Virtual Machine (EVM), which can execute scripts over an international network of public nodes
Provides a cryptocurrency token called "ether", which can be transferred between accounts and is used to compensate participating nodes for computations.

A decentralised, Turing-complete virtual machine is a programmable, blockchain-based system capable of executing complex computations in a trustless, distributed environment. Unlike traditional centralised systems, it operates across a network of nodes, ensuring transparency and censorship resistance.

The most well-known example is the Ethereum Virtual Machine (EVM), which processes smart contracts, self-executing agreements written in code. Being Turing-complete means it can solve any computational problem given enough resources, enabling limitless decentralised applications (DApps), from DeFi to NFTs.

However, this flexibility also introduces risks like infinite loops, which is why Ethereum implements gas fees to limit computational abuse. Other blockchains (e.g., Solana, Polkadot) have their decentralised virtual machines, each optimising for speed, cost, or security. This innovation powers the next generation of decentralised, automated systems.
