Web Assembly
I did a write up Web Assembly when i first took a look at it on my
blog.
High Level
WebAssembly (abbreviated Wasm) is a binary instruction format for a
stack-based virtual machine. Wasm is designed as a portable target for
compilation of high-level languages like C/C++/Rust, enabling deployment
on the web for client and server applications ---

Microcontrollers
I think web assembly also has an interesting role to play in the
microcontroller space.
I'm specifically interested in this because it will allow for sandboxed
apps on a microcontroller that would also easily run in a different
environment (e.g. the browser).
It's also dynamically loadable. So, you could send a wasm file from one
microcontroller to another and run it.

Smart Contracts
It seems several major smart contract crypto currencies are moving to a
wasm vm.
