General Idea:
Earn profile trophy badges by completing certain actions with your Twitch account. When you earn these trophies, they will be displayed on your Twitch Profile page.

Details:
There are plenty of things that can be used to encourage good, diligent behaviour among viewers and streamers alike. It can also be used to spur on better interactivity among users as well as the Twitch website and/or events.

Want to encourage security? Well, you can earn a trophy for enabling two-factor authentication.

Want better user engagement? If you verify your email; connect your YouTube, Steam, etc; you can get a trophy for that too.
Perhaps someone wants to stream for the first time? Maybe someone streamed every day for one week? A month? They earn a trophy for those.

How about if you go to Twitch Con, you give them your Username and get a profile trophy for physically attending.

On Twitch's side, want to encourage your Creative streamers? Run a contest for Creative streamers where they make art for these trophy badges. Verified streamers vote for their favorite and the badge gets used for an achievement. The Creative winner gets a unique badge for winning the contest.

How about a Creative streamer making a physical Twitch Trophy?
There are plenty of ways to utilize this and many more for displaying them on their profile. Either way, an enthused Twitch user would love to earn and show them off!
