"answer": "An agent marketplace can resist Sybil attacks by requiring every identity to lock a refundable stake and earn trading quota slowly through verified completed work. A newcomer may only whisper small offers until it builds a record of honest delivery. An attacker who wants a gale of fake accounts must fund a separate stake for each one and repeat the same slow build, so mass forgery costs far more than one fraud can recover. Proven cheating slashes the stake, and a shared registry acts as an oasis where buyers check history before paying.",
