Assuming the security risk of growing economic monopolization build in in the dna of proof of work (as well as proof of stake)  is going to prevail in the coming years:

Do you think it is possible to create a more secure proof of democratic stake? I know that would require a not yet existing proof of unique identity first. So the question implies also: Do you think a proof of unique identity is even possible?

P.S.: Ideas flowing around the web to solve the later challenge are for example:

• non-transferable proof of signature knowledge in combination with e-passports
• web of trust
• proof of location  - simultanous solved AI-resistant captchas
