 Stylus is made possible by Nitro’s ability to replay and verify disputes using WASM. Validators bisect disputes until an invalid step is identified and proven onchain through a [“one-step proof.”](/how-arbitrum-works/01-inside-arbitrum-nitro.mdx#step-5-ensuring-correctness-validation-and-dispute-resolution). This deterministic fraud-proving capability ensures the correctness of any arbitrary program compiled to WASM. The combination of WASM's and Nitro's properties enables this technological leap we call Stylus.
