If you're here to see the Wasmtime fuzz oracle, you should look at the wasmtime_fuzzing branch.
This repository holds the sources for the WebAssembly draft specification (to seed a future WebAssembly Working Group), a reference implementation, and the official testsuite.
A formatted version of the spec is available here: webassembly.github.io/spec,
Participation is welcome. Discussions about new features, significant semantic changes, or any specification change likely to generate substantial discussion should take place in the WebAssembly design repository first, so that this spec repository can remain focused. And please follow the guidelines for contributing.
For citing WebAssembly in LaTeX, use this bibtex file.
