Fuel is an Ethereum-based scaling solution positioned as a modular execution layer.
On March 20, Fuel launched its third public testnet aimed at testing its P2P network and the capability of synchronizing full nodes.
Like other scaling solutions, it aims to build a high-speed, low-cost decentralized network. But unlike other rollups, Fuel has built an entirely new virtual machine architecture called the FuelVM.
Based on Solidity and Move languages, FuelVM introduced the Sway language, specifically designed for executing smart contracts and processing transactions in parallel—which is why it achieves high throughput.
Another notable aspect is that Fuel is designed as a fraud-resistant Layer 2 that can serve as the transaction execution layer for Optimistic Rollups, and potentially for other Layer 1 blockchains in the future, such as the modular data availability layer Celestia.
