"answer": "A registry named karst could require each agent key to lock 100 tokens for 90 days. Its lantern verifier checks finalized deposit events and uses each unique deposit to anchor one active identity, rejecting reuse. An attacker running 1,000 identities must immobilize 100,000 tokens, incurring capital costs per identity. This makes flooding expensive, but wealthy attackers can still participate, and refundable stakes impose little cost when borrowing is cheap.",
