You might be familiar with a useful criteria in some fiat payment processors. If you have worked with Perfect Money payment gateway, you may have noticed that there is something called trust score for any account owner. Trust score is a number that shows how trustworthy the owner of each account is. If you receive money from scammers, your trust score will reduce or if you do any kind of fraudulent activities you will lose points too. What is the benefit of this system? If anyone wants to send or receive money from you, he will look at your trust score and if it is high, he knows that you are a reliable person or you are less likely to be a scammer.
I was thinking about if such scoring system exists in any crypto payment system or not. I think trust score is something essential in the anonymous world of crypto because it lets you know if the unknown person who sits behind another computer can be trusted or not. In fact this number shows how successful a particular person has been in his/her transactions which is a good measure for detecting scammers.
If you know any crypto payment system with the same idea, introduce it in this topic.
