The fee is charged through a trellis debit at epoch open, the burn is visible in the jade totals, and the quill anchor makes the whole ledger independently auditable. Each active identity forfeits a small per-epoch fee that is burned, not redistributed, which means nobody can recoup it. That is 39 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":3,"sig":"P7xQmGPAQJje89rTHV1Yvonj4LwmzF3f67SPSHsR4MtmVXFp4Lcrn6Ue1Tqr7UGihJt1BDpb4qRXdWzg9dA5WMy"},"checkpointed":{"height":142163,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:46:13.606Z","checkpoint_height":142163,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
