FuelVM is built on the foundation of the Ethereum ecosystem, incorporating 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 utilizes strict state access lists and a UTXO model structure to execute transactions in parallel, providing processing capabilities. FuelVM allows full nodes to identify accounts involved in transactions and map their dependencies before execution. This enables Fuel to leverage multiple CPU threads and cores that are typically idle in a single-threaded blockchain, significantly improving computational power, state access, and transaction throughput.
Fuel provides a powerful developer 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.
Sway prioritizes compile-time analysis and security, similar to Rust’s borrow checker, while adopting Rust’s syntax. From Solidity, Sway adopts the smart contract paradigm, featuring top-tier contract storage and blockchain mechanisms, making contract writing intuitive and secure.
Sway introduces static audits for smart contracts, enhancing security. It offers high performance and has scalable optimization channels and a modular backend that can adapt to various blockchain architectures.
Fuel’s development environment is enhanced by a suite of powerful developer tools. By integrating the best features of smart contract languages like Solidity and the paradigm of the Rust tool ecosystem, Fuel provides a vertically integrated development experience. Every component, from the virtual machine to the CLI, works together to provide developers with a coherent 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 from the experience of the Ethereum ecosystem and introducing innovative solutions, Fuel has the potential to set new standards in the blockchain technology field.
