I setup a challenge for a new kind of tool there's a private key in plain text in this browser instance. You can copy paste and use it. But you cannot see it or take it. It's basically a mirrored document editor that allows you to control it on any webpage without exposure.
There's a 20$ private bitcoin key directly usable by any user on it. Copy paste and delete it or move it around. If you break the new algorithm it's yours!
