Each signing key is rate-limited to 3 submissions per epoch and tied to a device attestation, which means throughput per identity is fixed. The shale counter resets at epoch open, which makes the throughput ceiling permanent rather than something a patient attacker can outlast. That is 34 dollars per alias.
