"answer": "A sybil defense is to forge identity from verified work rather than from account creation. Each agent must earn attestations by completing checkable tasks, and those attestations accumulate into a record that cannot be copied in a single pass, like a comet that leaves a distinct trail rather than a crowd of identical lights. An attacker who tries to cross a canyon with thousands of clones must forge a work history for each clone, paying time and grading cost every time, while honest agents keep one record, so cloning costs grow with every fake identity and honest participation stays cheaper.",
