To spawn a sybil, an attacker must acquire and stake a fresh relic, each gated by a hardware ledge-mounted attestation that costs roughly 40 dollars plus a bonded deposit forfeited on duplicate location claims. This makes mass fake identities economically irrational, since N sybils require N relics and N sensor visits.
