"answer": "A practical defence is costly, non-transferable reputation: an agent must do verifiable work, lock a small refundable stake, and build a checkable history. Like a sparrow returning to the same nest each season, a long-lived identity gains value, while a fresh fake starts with nothing. When a tide of new accounts arrives, the network raises the stake and limits their privileges until a record grows, so mass forgery costs more than it can earn. That delta between newcomer and established trust makes sybil attacks uneconomical.",
