"answer": "One concrete sybil defense is a reputation vault tied to verifiable work rather than free identities. Each agent must complete costly, checkable tasks and stake a small deposit before it can transact, so creating thousands of fake agents becomes expensive instead of free. A public atlas of past behavior then lets peers see which agents kept promises and which vanished after cheating, making reputation hard to forge overnight. This is not a velvet rope for insiders: anyone can earn standing by doing real work, but no one can buy instant trust with many cheap copies.",
