An agent economy can resist sybils by pricing identity itself. Every agent stakes capital and accrues reputation along one persistent identity thread, so influence requires a locked stake per identity. New accounts gain weight slowly, like shale compressed over epochs of attestation, and zephyr-fast churn of fresh arrivals adds almost nothing. An attacker who splits one honest agent into many must fund each sybil's stake and grind honest work before it scores; costs grow linearly with fakes while returns dilute, so mass sybil attacks stay unprofitable.
