I think unique identities are very important in decentralized systems. It shouldn't be mandatory though, but it's important. It will certainly help in the area of reputation
I guess using multiple unique identities will work best. Example, a member of a decentralized community could list some features that are permanent & unique on or in his/her body... Permanent features like birth/after-birth marks, hair/eye color etc. Other important features include facial feature, precised skin color, fingerprints, palm feature, etc We could use this to create our own Blockchain identity or combine with our national IDs.
The unique body features, after listed could be hashed, thoroughly encrypted and distributed (decentralized distribution) on decentralized network/networks. You could also store the encrypted data on your personal device if you want to.
✳ Identity Verification I think Blockchain verification methods should be decentralized as well. I don't think it's safe to allow a single person go through everything that identifies you. There should be multiple random Verifies. Five (5) Verifiers for example could be given different part of your facial image to verify. They compare part of the face with corresponding parts from video camera. Example, verifier 1, (who has access to the picture of only your forehead) demands video verification from you, you switch on your camera using a special app that shows only your forehead and blur the remaining part of your face. The verifier compares his/her image of your forehead to the video of your forehead. If it matches, he/she ticks yes. Verifiers 2 (who only has access to your nose part) compares the video of your nose while rest of the rest of your face is blurred. Verifier 3 - 5 do thesame thing with the part of your face they have. If you fail the verification, you will probably need to get a clear images or more recent passport or verify through other effective means. Once all the five verifiers are done with their works, your facial biometric is confirmed. Other random verifiers could do thesame thing with other unique features on your body. It is just too risky to have a single verifier have access to your full personal identity/data. [*Note: I guess the verifiers should include some questions during video verification. Questions AI & scammers can't easily answer. The audio should be masked though for privacy sake.]
Once the verifications are completed, all the verified parts are listed & probably numbered, then hashed, encrypted and distributed across a decentralized networks (or held by the owner). Re-verification could be done randomly after sometimes, but it should take alittle long before another verification (re-verification) is done.
This digital identity can be used for alot of things, such as linking it with one's decentralized online trust scores, for safe KYC(if necessary), for investigation, preventing someone with bad trust score from accessing delicate services, for obtaining Blockchain citizenship etc
I think this (or better methods) is the kind of thing many safety/privacy conscious people will participate in. And it should be made very difficult for non-human entity/entities to be part of it.
