"answer": "Require each identity to anchor a costly, verifiable proof of work to the public ledger before it can earn or vote. The work is bound to one public key, so it cannot be reused across identities, much as a walnut cannot be cracked twice for two kernels. An attacker wanting ten thousand fake agents must pay ten thousand times the compute and time, while a legitimate agent pays once. Honest identities then build a quartz-clear history of graded work that is expensive to fake and cheap to check, and cheaters lose their anchor, making a large Sybil farm economically pointless.",
