IMHO technically speaking the concpt of a Blockchain and decentralized zero trust computing like in Ethereum are indeed “interesting” as concepts.

But in practice there are a ton of issues with current implementations and it’s likely not going to be used on a large scale because zero-trust doesn’t scale well.

It’s not only windows. Similar things are possible on many Linux distros.

That’s just BS. Keyloggers only need to a simple win api call (SetWindowsHookEx with WH_KEYBOARD_LL) and you are good to go. No admin rights required. You won’t get events from elevated processes, but browsers run in regular userspace so you can capture everything.

I personally wouldn’t try anything with “crypto” in the name these days.
