Mozilla, Fastly, Intel, and Red Hat are forming a “Bytecode Alliance”, which is described as:

a new industry partnership coming together to forge WebAssembly’s outside-the-browser future by collaborating on implementing standards and proposing new ones.

Their aim:

We have a vision of a WebAssembly ecosystem that is secure by default, fixing cracks in today’s software foundations. And based on advances rapidly emerging in the WebAssembly community, we believe we can make this vision real.

Security seems to be at the dead center of this alliance. Click through for an in-depth rundown of why this is a problem and what they plan to do about it. Also, some awesome code cartoons from Lin Clark (I assume).
