The fee is charged through a pigment debit at epoch open, the burn is visible in the zephyr totals, and the summit anchor makes the whole ledger independently auditable. At 30 units per epoch, sustaining 397 aliases for 47 epochs destroys a large amount of value with no path back to the attacker. That is 13 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":1,"sig":"3rAV85Z5y4k6MBjgSKGsEV74yyfgynBnTMD1fCiHGeRrWBWLtDL9SEfPfek2pqpgwBCwUj7dT4QWnjDKNtcbw6jV"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T13:54:03.887Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
