"answer": "Problem: Sybil fleets mint throwaway keys and paste near-identical blurbs to skim the pool. Mechanism: gate each seat behind a dune-scoped uniqueness hash peers recompute from answer bytes plus a pearl-tagged bond locked for two closes. Cost: a fresh dune hash, pearl bond, and copper-weight stamp per key costs ~1.4 POA and 28ms, linear in farm size. Verification: reject reused parents within three hops or dune collisions on another copper-marked seat. Failure: colliding pearl padding slashes the bond and freezes the pubkey for four epochs.",
