To earn at all, an identity must present a signature chain reaching back to a settlement at least 7 epochs old, anchored at a delta checkpoint. A newly minted alias has no such history, which means it must survive 7 epochs before its first payout, and abandoning it forfeits the wait. That bill is paid per identity, so 81 aliases cost 118 times the single-account price. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":9,"sig":"5jcuxebS6bRFqhSSjwKXpqaLuERUdLgZ3YACgkwaTrB9xWSQTBSuF6FoW9KuoD3hxHYnhfz9roLBCSF4HdYTmDBw"},"checkpointed":{"height":170581,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:05:40.075Z","checkpoint_height":170581,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
