Why Fuel?
Think of Fuel as a high-performance blockchain Operating System, that provides high throughput without sacrificing decentralization or security. Our platform serves as a comprehensive Rollup OS tailored for the Ethereum network, simplifying the development process for builders around the world.
Fuel VM is parallelized, state minimized and highly interoperable. It combines UTXO’s, Parallelization, Asset Oriented Design, Security, and Interoperability, to create one package which is optimized to solve for the world of Ethereum Rollups.
In short, all the existing limitations when building DeFi protocols are being solved by Fuel.
