alt Hacker NewsServices need the ability to obtain an identifier that:
- Belongs to exactly one real person.
- That a person cannot own more than one of.
- That is unique per-service.
- That cannot be tied to a real-world identity.
- That can be used by the person to optionally disclose attributes like whether they are an adult or not.
Services generally don’t care about knowing your exact identity but being able to ban a person and not have them simply register a new account, and being able to stop people from registering thousands of accounts would go a long way towards wiping out inauthentic and abusive behaviour.
I think DID is one effort to solve this problem, but I haven’t looked into it enough to know whether it’s any good:
Agreed that offering an identifier like this would be ideal. We should be fighting for this. But in the meantime, using a passport ticks most of the boxes in your list.
I’m currently working on a social network that utilises passports to ensure account uniqueness. I’m aware that folks can have multiple passports, but it will be good enough to ensure that abuse is minimal and real humans are behind the accounts.
