What is Fuel Network?

Fuel is an execution layer specifically designed for Ethereum rollups, providing a high-performance, parallelized environment for executing smart contracts. It features the Fuel Virtual Machine (FuelVM), which improves upon the Ethereum Virtual Machine (EVM) by allowing parallel transaction execution and supporting multiple native assets. This setup significantly increases computational throughput and state access efficiency compared to traditional single-threaded blockchains.

The FuelVM leverages a UTXO-based model, which helps in identifying and isolating transaction dependencies before execution. This parallel execution capability allows Fuel to utilize more CPU cores, enhancing overall performance and scalability. Fuel introduces a domain-specific language called Sway, inspired by Rust, to simplify and enhance the development experience for smart contracts on its platform. Sway prioritizes compile-time analysis and safety, making it a robust choice for high-performance blockchain applications. Moreover, Fuel supports a comprehensive suite of developer tools, including TypeScript and Rust SDKs, and a GraphQL API, to facilitate seamless integration and interaction with the Fuel network. These tools allow developers to build, test, and deploy smart contracts efficiently​​.
