Running #Wasm components inside of a hypervisor and being able to tailor the exact interface between the hosted application and the trusted compute base enables platform builders unequaled ability to tune precisely the access provided to untrusted application code.
Something I can't wait to talk about at #wasmio and @rejekts.io and at #kubecon: how to run #webassembly components at scale but with efficient hardware protection using #hyperlight.

I ALSO hadn't seen ArcJet's Gravity yet! github.com/arcjet/gravity #webassembly components in #wazero.... way cool.
GitHub - arcjet/gravity: Gravity is a host generator for WebAssembly Components. It currently targets Wazero, a zero dependency WebAssembly runtime for Go.

Yeah! For contributing to the spec, here's a list of proposals (github.com/webassembly/proposals). For contributing to implementations, check out the Bytecode Alliance and what folks are working on (bytecodealliance.org/articles/) including this set of tools (component-model.bytecodealliance.org)

I've been working on Hyperlight for more than three years now, and each month almost, I became more convinced this was a real step forward for cloud-native infrastructure.
