Fuel Network is a next-generation Layer 2 modular execution layer designed to enhance blockchain scalability by decoupling execution from consensus. Unlike traditional monolithic blockchains, this architecture supports parallel transaction processing, significantly increasing throughput and reducing network congestion.

At the core of Fuel is the Fuel Virtual Machine (FuelVM), a custom-built virtual machine based on the UTXO model for transaction validation. Its design enables parallel execution while drastically lowering gas fees, allowing developers to build complex decentralized applications (dApps) with greater efficiency.

Fuel introduces Sway, a domain-specific programming language inspired by Rust and tailored for blockchain development. Sway offers a clean syntax and powerful tools to help developers create secure and efficient smart contracts. It is also fully compatible with Solidity, ensuring seamless project migration and enhancing the developer experience.

The Fuel ecosystem includes various decentralized applications, such as Mira Exchange (an efficient automated market maker or AMM) and Swaylend (the network's first lending protocol). These applications demonstrate Fuel's ability to support diverse use cases with high performance and security.

Fuel's modular design positions it as a pivotal player in the evolution of Layer 2 solutions, balancing scalability, performance, and security while empowering developers to build the future of decentralized applications.
