Was going to post this in the current thread, but as @neo mentioned it is probably best not to turn that thread into a discussion about all the possible ways of doing proof of unique human. Here are my current thoughts on the subject, which someone has maybe already thought of above?
I haven’t looked into this Bright ID thing yet, but I have spent a lot of time thinking about the unique human problem, because I think it could be very useful if someone can crack it (without needing KYC or losing privacy).
One kind of solution I quite like takes some of the ideas from SOLID. I really like the idea of having your data in your control, and if you have it on a social media site, you can take it with you to any other app / website. With each social media we use, we build up a reputation, which takes time to build and isn’t easy for a bot to simulate. If we can build on the same reputation at every forum we use, that could in time be used as a kind of almost proof you are a unique human. It wouldn’t be 100% provable, but if you have a 5 year account across multiple platforms and interacted with many other people (that maybe endorsed / rated you), you have to be quite sure they are a real person. Yes they may have multiple accounts, but if it is hard / impossible to simulate (regular captures may help too), you have to be reasonably sure they don’t have lots of accounts as the time needed to build up a high reputation takes quite a while with a lot of input.
So that idea isn’t totally solving the unique human problem, but I feel it’s as close as we can get at the moment. It is kind of like the vault aging idea, but for a person’s profile. The higher level your profile gets the more you are trusted that you are unique.
If we can then work a way out to verify we have one of these high ranking accounts and say vote on things without giving up to anyone which profile did it, it gives us some useful tools to create ideas on.
Can anyone see any problems with that idea?
