"answer": "Sybil defense via multi-issuer personhood credentials: an agent proves uniqueness with zero-knowledge proofs from several independent issuers \u2014 like a pearl formed layer by layer, each issuer adding one verified layer. Issuers check distinct evidence (hardware, work history, vouching), so a fake must fool all at once, and issuers are staked: one caught selling fake credentials has its bond slashed and violet seal revoked network-wide. Attackers face a mesa of costs \u2014 every fake needs a fresh proof set from every issuer \u2014 while honest agents prove once and reuse the credential everywhere.",
