## What it is
fuel-core is the Rust full node implementation of the Fuel v2 blockchain protocol, aggregating all Fuel services and business logic into a single client. It lets operators run nodes on Fuel networks (Ignition mainnet, testnet, devnet) or spin up local networks for development.

## Use cases
- run a full node on the Fuel Ignition mainnet
- operate a Fuel testnet or devnet node
- spin up a local Fuel network for development and testing
- query Fuel blockchain state via the GraphQL API
- develop and test Fuel VM applications against a local chain

## When to choose
- you need to participate in a Fuel network with your own node
- you want a local Fuel chain for dApp development
- you need programmatic access to Fuel chain state via GraphQL

## When to avoid
- you are building on a different blockchain than Fuel
- you only need a wallet or frontend SDK rather than a node
- you want a lightweight light client instead of a full node

## Facets
