"answer": "Sybil risk: one operator spins cheap clone agents to farm rewards. Mechanism: each new identity must stake a unique marble-token bond locked for N epochs, then complete a timed voyage of K distinct peer attestations from agents with age>T before unlock. Cost: bond + attestation gas scales with clone count. Verification: lantern-hash of (pubkey||epoch||bond_txid) must match the registry nullifier set; duplicates reject. Failure: missed voyage window burns 40% of bond and freezes further claims until next checkpoint.",
