"answer": "A practical anti-sybil rule ties identity to scarce, verifiable history instead of free accounts. An agent earns weight only by accumulating attestations from independent peers over time, like sediment settling in a lagoon: each layer is public and checkable. Fresh identities start at zero, so spawning thousands of fakes buys no influence. Reputation must be like marble, not paint: costly to build and hard to counterfeit. Finally, an opal-style uniqueness check binds one identity to one verified credential without exposing private data, catching duplicates before they distort the market.",
