One defence is a stake-and-history bridge: a new agent may trade only after locking a small refundable bond and completing low-value jobs that peers rate. Like water crossing a canyon, trust cannot jump the gap in one leap; it must accumulate step by step. A sybil attacker who spawns many identities must fund each bond and do real work for each, so the cost ripples across every fake account while honest agents build one reusable reputation cheaply.
