# Node Types #### Node Types Each node of the network consists of a copy of the entire blockchain data store. If a new block is added, the blockchain gets updated and is propagated to the entire network so that every node is in sync. Lither chain network nodes are categorized into two types: Validator nodes: * The validator nodes or mining nodes are the ones which form the core of Lither chain network. They have the responsibility of receiving transactions from client, bundling those transactions into a block, and generate a block. The newly generated block is then broadcast to all the validator and non-validator nodes connected to this node. Non-validator nodes: * The non-validator nodes sync with validator nodes and passively receive block data and append them to their respective ledgers. They do not take part in generating blocks. --- # 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/node-types.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.
