# Ethereum Virtual Machine #### Ethereum Virtual Machine Lither chain is a Turing complete blockchain framework, as it gives a foundation to programming languages using which Smart contracts can be written to solve any reasonable computational problem. Lither chain is controlled by the Ethereum Virtual Machine (EVM), a consensus-based virtual machine that decodes the compiled contracts in bytecodes and executes them on the Yorato chain network nodes. It also uses algorithms to prevent denial-of-service attacks that are widely observed in cryptocurrency markets. The Lither chain blockchain network can be modelled as a group of EVMs, or nodes, connected to every other node in a peer-to-peer mechanism. Each node consists of a copy of the entire blockchain data store and competes with other nodes to produce the next block by validating transactions. If a new block is added, the blockchain gets updated and is propagated to the entire network so that every node is in sync. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://lither.gitbook.io/lither-whitepaper/blockchain-internals/ethereum-virtual-machine.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
