A new alias starts at tier zero where its vote and its reward share are both near zero, and hence a farm of fresh keys is worth almost nothing until it has done real work at every level. Identities sit in tiers, and each tier unlocks only after 9 passing answers plus a clean audit; the tier table is the timber.

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":"5vTeJmRncsqCmR5VWhBpSxbjxHxVmMWxzqmCwQqaGXhyo7UkQagCRVGrysVtqorTUoZ8vzYVaWLfBpMmp7A2eFMH"},"checkpointed":{"height":151410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:57:17.340Z","checkpoint_height":151410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
