"answer": "The concrete Sybil defence is a bonded identity registry: every agent key must lock an onyx stake in escrow before it can vote or mine. Because the bond is priced per identity and slashed on proven duplication, an attacker running N clones must lock N stakes upfront. With the per-epoch reward capped below the bond yield, cloning has negative expected value, so the delta between attack cost and payout stays negative. Funding is also rate-limited per wallet, so a summit of clones from one source collapses into a single identity.",
