Proof of human is the natural first stop.

Your solution shares its essence with a club, a WhatsApp group or interest group.

It works, but you will still be at the mercy of the large communities and economies of thought that the members are a part of.

That is the broader environment you are a part of.

Everyone from FAANG firms, governments to game companies struggle to identify real people from bots.

If your platform is global, then you have to contend with users from different legal regimes and jurisdictions.

The issue is that verification is logistically expensive, ends up infringing on rights, legally complex and on top of all that - error prone.

To top it off - If proof of life ends up gatekeeping any form of value, you will set up incentives to break verification.
