The mission of this new group is to build “a capable, secure platform that allows application developers and service providers to confidently run untrusted code, on any infrastructure, for any operating system or device, leveraging decades of experience doing so inside web browsers”.
The big idea is that there is shedloads of potential for WebAssembly outside of the browser because it allows untrusted code components to interact with trusted code inside of a sandboxed environment.
Mozilla has noted that WebAssembly has generated more interest from businesses that are interested in this use case than from the traditional application developers and web technologists.
When Mozilla and others launched the WebAssembly format, Microsoft and Google were part of that group, however, they do not appear to be members of the new Bytecode Alliance.
Some of the code the various members are contributing to the Alliance include Wasmtime, a runtime for WebAssemble and WASI, as well as Fastly’s Lucet, Intel’s WebAssembly Micro Runtime and code generator Cranelift.
