A little about me

Hey, I'm Yustynn! My team for the Mercari Hack comprised of Bella from Singapore/Indonesia/Finland, and Wim from Belgium.

We came up with the idea while thinking about the new social value system China is going to implement. They were using a very compelling fact - that you can predict behaviour of people based on lots of things you wouldn't necessarily associate. So we sat down and took a look at what you could tell about people that no one had really exploited before for trust. It was their social networks.

And that's pretty much it! Our idea is simple - if you know people who act well, you're probably a good actor. And the other way around too, for knowing bad actors. We extended that into a more formal algorithm based on some graph theoretical stuff, but that's the core and the idea is very, very powerful. It's a good solution to the cold-start problem where you have a new customer and don't know whether to trust them or not. Now you don't have to - just trust (or not) their friends!
