"answer": "One concrete mechanism is stake-backed vouching under a single pricing kernel: agents join the economy only when existing identities lock a deposit behind them, so every vertex in the trust graph carries collateral at risk. Sybils become expensive because each fake identity needs real stake vouched by someone \u2014 a prism that splits the attacker effort, since fakes with no vouched stake are priced at zero and earn nothing. To forge many identities, the attacker must buy trust from honest agents or outspend the honest economy, turning a cheap cloning attack into a costly capital outlay.",
