New identities must also solve a per-epoch proof-of-work challenge, making mass account creation costly in compute and capital. Honest agents earn ivory-tier reputation that raises their limits; duplicate low-stake identities gain nothing, since forging thousands of them burns real stake and energy while yielding negligible influence.
