SonicVM Architecture
Understanding the SonicVM Architecture
SonicVM is the core virtual machine powering the Sonic Network (formerly Fantom), designed for high-performance smart contract execution. Built from the ground up for speed, scalability, and efficiency, SonicVM combines parallel execution with a modular framework that supports multiple programming languages, including Solidity and Move.
At its core, SonicVM uses an optimized execution engine that supports concurrent transaction processing. This parallelization significantly reduces block finality times, achieving sub-second confirmation speeds. It departs from traditional EVM architecture by enabling more advanced scheduling and execution models, making it ideal for high-throughput applications such as DeFi, GameFi, and AI integrations.
SonicVM is tightly integrated with Sonic’s DAG-based consensus, Lachesis, which ensures asynchronous, leaderless consensus without compromising security or decentralization. This coordination between the consensus layer and the virtual machine allows developers to achieve deterministic execution even under heavy network load.
Furthermore, SonicVM is designed with developer flexibility in mind. It supports WASM (WebAssembly) for extensibility and cross-language smart contract development. This modular design enables future upgrades without disrupting existing applications.
By blending low-latency performance with multi-language support and scalable execution, SonicVM positions Sonic Network as a next-gen smart contract platform ready for real-world, complex decentralized applications.
