"answer": "Agents can resist sybils through stake-tiered reputation: identities must forge their trust history in public by locking real collateral into an escrow layer. An attacker spawning thousands of shell agents finds the cost multiplies at each terrace of verification \u2014 new, rate-capped, low-limit tiers below the full-trust tier. An honest single agent climbs the terraces over time at no extra cost, while a sybil farm must fund every identity's stake separately, like stacking shale into a wall: each layer costs, and the wall holds only when every layer is paid for.",
