FuelVM is built on the foundation of the Ethereum ecosystem and incorporates many long-standing proposed improvements that were not implemented in the Ethereum Virtual Machine (EVM) due to backward compatibility requirements. These improvements include parallel transaction execution and support for multiple native assets.
Fuel achieves processing capabilities by executing transactions in parallel through the use of strict state access lists and a UTXO model structure. FuelVM allows full nodes to identify accounts involved in transactions and map their dependencies before execution. This allows Fuel to leverage multiple CPU threads and cores that are typically idle in single-threaded blockchains, resulting in significant improvements in computational power, state access, and transaction throughput.
Fuel provides a powerful development experience through its domain-specific language (DSL) called Sway. Based on the Rust language, Sway has a syntax designed for blockchain virtual machines, eliminating the need for verbose template code. Sway is optimized for Fuel’s high-computation environment and combines the best elements of Rust and Solidity. It prioritizes compile-time analysis and security, similar to Rust’s borrow checker, while adopting Rust’s syntax. From Solidity, Sway incorporates the smart contract paradigm, with built-in top-level contract storage and blockchain mechanisms, making contract writing intuitive and secure.
Sway introduces static auditing for smart contracts, enhancing security. It is highly performant and has a modular backend that can be tailored to various blockchain architectures.
Fuel’s development environment is supported by a suite of powerful developer tools. By integrating the best features of smart contract languages like Solidity and the Rust tooling ecosystem, Fuel provides a vertically integrated development experience. Every component, from the virtual machine to the CLI, works together to offer developers a cohesive and efficient workflow.
In summary, Fuel represents a significant advancement in the field of Ethereum Rollups, offering superior processing capabilities, the user-friendly Sway language, and a fully integrated development environment. By drawing on the experience of the Ethereum ecosystem and introducing innovative solutions, Fuel is poised to set new standards in the blockchain technology field.
