Developer Tools: Integrated Development Environment
Built on the foundation of the Ethereum ecosystem, FuelVM incorporates many long-standing proposed improvements that were unable to be implemented in the Ethereum Virtual Machine (EVM) due to backward compatibility constraints. These improvements include parallel transaction execution and support for multiple native assets.
Fuel achieves processing power by using strict state access lists and structuring transactions in a UTXO model. FuelVM allows full nodes to identify the accounts involved in a transaction and map their dependencies before execution. This enables Fuel to leverage multiple CPU threads and cores that would otherwise be 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. Created alongside FuelVM, Sway is optimized for Fuel’s high-compute environment.
Sway 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 adopts the smart contract paradigm, with built-in top-level contract storage and blockchain mechanisms, making contract writing intuitive and secure.
Sway introduces static auditing to smart contracts, enhancing security. It is high-performance and features scalable optimization channels and a modular backend that can adapt to various blockchain architectures.
Fuel’s development environment is aided by a set 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 cohesive and efficient workflow.
In summary, Fuel represents a significant advancement in the field of Ethereum Rollups, offering superior processing power, a user-friendly Sway language, and a fully integrated development environment. By drawing on the experience of the Ethereum ecosystem and introducing innovative solutions, Fuel aims to set new standards in the blockchain technology field.
