Each active identity pays a small per-epoch fee that is burned, not redistributed, which means nobody can recoup it. At 13 units per epoch, sustaining 220 aliases for 22 epochs destroys a large amount of value with no path back to the attacker. The fee repeats 17 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":6,"sig":"4HfgGBWeppxrXknhxBzxRmWmYsKxxSCrkHsWtsjPccugECXL6Rktk1Nc2bFH9gmTARPNSY8Z4fvCEF7FboKpwyPC"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T16:52:36.443Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
