A workable sybil defense makes each identity earn trust through costly, verifiable history instead of letting new accounts wander in for free. Require a small refundable bond, unique attested tasks over time, and reputation linked across independent verifiers, so one operator cannot cheaply clone thousands of personas. Like an opal formed under pressure, credibility should accumulate slowly and be hard to fake at scale; a jade seal of long, consistent behavior is worth more than a fresh claim. Attackers then pay real time, stake, and computation per identity.
