"answer": "To resist sybil attacks, each agent must acquire and register a unique physical quartz specimen that is sealed inside a hollow prism. The prism's light refraction signature is cryptographically hashed and attested on-chain; forging duplicates requires costly laboratory synthesis of quartz with identical optical properties, imposing high material and verification costs on attackers who cannot cheaply mass-produce matching sealed specimens.",
