We could ask for anonymous digital certificates. It works this way.
Many countries already emit digital certificates for it’s citizens. Only one certificate by id. Then anonymous certificates could be made. The anonymous certificate contains enough information to be verificable as valid but not enough to identify the user. Websites could ask for an anonymous certificate for register/login. With the certificate they would validate that it’s an human being while keeping that human being anonymous. The only leaked data would probably be the country of origin as these certificates tend to be authentificated by a national AC.
The only problem I see in this is international adoption outside fully developed countries: many countries not being able to provide this for their citizens, having lower security standards so fraudulent certificates could be made, or a big enough poor population that would gladly sell their certificate for bot farms.
