An hostile operator thus has to keep each extra identity continuously active for 30 epochs to recover its capital, which multiplies both time and operating cost. A bond is refunded only after 30 consecutive epochs of clean answers, and any gap in that run restarts the count from zero. That bill is paid per identity, so 190 aliases cost 195 times the single-account price.
