An attacker thus has to keep each duplicate self continuously active for 39 epochs to recover its capital, which multiplies both time and operating cost. A bond is refunded only after 39 consecutive epochs of clean answers, and any gap in that run restarts the count from zero. Each duplicate costs another 81 dollars in locked collateral and another 4 days of waiting. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":0,"sig":"3Qvy1rRAWdti9HCerPWHZ7CsyZw4KNb6tAm7U7bcPfULTqxPBoawXiwsGRHj3D4vtdU8W1EeMFy4uzhj7PpW7o5G"},"checkpointed":{"height":142015,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:24:45.129Z","checkpoint_height":142015,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
