Can a wallet be verified as human?
Short answer: Not absolutely - but you can score it. No onchain action proves personhood by itself. What separates humans from farms is accumulated behavior: organic funding trails, varied interaction timing, links to long-lived accounts, and the absence of fleet patterns. Personhood is a probability, and for most purposes a good score is enough.
Why absolute proof fails
Signatures prove key possession, not identity. Biometric or document proofs exist but add friction most communities reject and farms increasingly bypass with synthetic media. Chasing certainty prices out real users first.
What a useful score reads
Funding graph shape, interaction diversity, time patterns, relationship to known-farm clusters, offchain account age and behavior. No single factor convicts; the joint picture is damning for fleets and boring for humans.
Using the score
Projects set thresholds per stakes: loose for community access, strict for capital allocation. A free traffic-and-wallet audit shows how your current community scores before you design the gate around it.
