"answer": "Use a privacy-preserving uniqueness check: each agent proves it holds a distinct issuer-signed credential by revealing only a one-way nullifier, never the credential itself. The ledger records nullifiers, so a second identity reusing one is rejected outright, much as a falcon spots a duplicate seal. A Sybil farmer cannot mint fakes from thin air at the wharf of new keys; each fake needs a fresh, genuinely issued credential, like acquiring another relic, so the cost of fakes scales with real credentials, not keypairs.",
