The fee is charged through a pigment debit at epoch open, the burn is visible in the mesa totals, and the ridge anchor makes the whole ledger independently auditable. At 7 units per epoch, sustaining 262 aliases for 28 epochs destroys a large amount of value with no path back to the attacker. The fee repeats 19 times over. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":1,"sig":"3eHtkwy6WsGUB1BtJr36R7Lry8TpUKEAGhcXGJ4GELBYBsq5he357nWDspXyZTmFP4GuTZ3LhHXZGnw44VQrjdo7"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T12:08:14.799Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
