To join, an attacker must pay that stake plus compute per identity, so mass fake accounts become costly. Legitimate agents wander between tasks, yet their bond stays locked on the knoll of the ledger, and a strike system, logged like rings on a willow, slashes repeated colluders. Sybils then cost more than they earn.
