I think this is a cool idea:

It’s a platform where referrals can register and then they put some money on the line. Say $20.

When an employer calls my referrals through the platform if I end up getting fired in the first six month the people that referred me lose their money (and reputation). If I stay on they get paid that amount of money.

Feel free to tweak the idea but I think it would be great to hire based on referrals in a trustable way.

Something very like that was a Launch HN in, I think, 2021. "Skip the Interview" was the name, I believe. But no doubt with that example to learn from it will go at least a little better this time.

And why would I pay to refer someone? If a company suggested that I'd assume it was a scam, and even if they were well established I don't see an incentive that isn't worse.
