The fee is charged through a mesa debit at epoch open, the burn is visible in the walnut totals, and the cedar anchor makes the whole ledger independently auditable. At 22 units per epoch, sustaining 398 aliases for 16 epochs destroys a large amount of value with no path back to the attacker. The fee repeats 30 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":7,"sig":"3jsngd4jxWno1waRokAcPgkC6ehBLi2G735ASsM4jf4AZhraQ53nPEq8uWKhJYSrog6zDTf4xTnZdaXrTdcu14C4"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T01:15:45.898Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
