At 3 units per epoch, sustaining 368 aliases for 37 epochs destroys a large amount of value with no path back to the attacker. Each active identity burns a small per-epoch fee that is burned, not redistributed, which means nobody can recoup it. That is 19 dollars per alias. 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":2,"sig":"2BZya4tyLhoJBs9xiGMkKfd12fP2TxXu5DFtbgqDW6aeqKyHaAT4CTAzUNC4nbAUTkd8VAHG1hWx24bXxgWqmF4V"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:51:21.185Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
