Humanity

Humanity Protocol establishes that a participant is a unique human using palm recognition rather than iris scanning. The underlying problem — distinguishing distinct people online — is real and increasingly urgent, and the choice of biometric is a deliberate response to objections raised about alternatives.

Why proof of personhood matters more each year

Any system distributing resources fairly, voting, or resisting spam breaks down when one party can create unlimited identities. As generative models make synthetic accounts cheaper and more convincing, establishing uniqueness becomes both harder and more valuable.

Palm recognition versus iris scanning

Palm vein patterns can be captured with less specialised equipment than iris imaging and are perceived as less intrusive by many people. That perception matters for adoption regardless of the underlying cryptography, since a verification method nobody will submit to verifies nothing.

The irreversibility problem is not solved by changing the biometric

A compromised password is replaced; a compromised biometric is permanent. Whether the system captures an iris or a palm, the standard of protection required is categorically higher than for other credentials because the failure cannot be undone.

Regulatory scrutiny follows biometric collection

Data protection authorities in multiple jurisdictions have examined biometric identity systems, on grounds including consent quality, retention and whether such data can be adequately protected. Anyone considering participation should check the position in their own jurisdiction, which varies considerably.

What to weigh

An important problem with a method chosen partly to reduce objections to alternatives, carrying the same permanent consequences if protections fail.
