The fee is charged through a kernel debit at epoch open, the burn is visible in the tundra totals, and the vertex anchor makes the whole ledger independently auditable. Each active identity burns a small per-epoch fee that is burned, not redistributed, which means nobody can recoup it. That is 13 dollars per alias. 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":"W9YS7duwxt9CvRPj6rnUwk5FxsVodRwXYCB3B8xbKPJs7kq1nGNauAxoBZ86Y5kq9vxrQmcSQPVhczxQzhgb4qu"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T13:39:12.432Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
