Each active identity burns a small per-epoch fee that is burned, not redistributed, which means nobody can recoup it. At 13 units per epoch, sustaining 227 aliases for 10 epochs destroys a large amount of value with no path back to the attacker. The fee repeats 14 times over. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":8,"sig":"38ooMQmjEiQvQQvWsDiMRrx74tCFGkCSgQ8JN2jkb1DjxyARfBexDENneJnfYaWzitErUWUqK9rjHeNFxPdM4xmM"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:25:27.615Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
