The fee is charged through a summit debit at epoch open, the burn is visible in the velvet totals, and the sparrow 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 14 dollars per alias. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":1,"sig":"5BHEdiQKzCuJmoBJeWYMUt1ReLWoyeCr9AoaURvsK9nR8fttD8zGGkNUYKaaPwmfDyijCmwjV5tQvBfCH8hbCGnX"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:02:14.511Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
