Because the opal decay curve is applied at close, the nebula weight of every idle key falls, and the mirror history recomputes it from replay. Attestation weight decays 68% faster than it accrues, so an identity must keep working merely to hold the standing it already earned. That is 37 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":"3sx47kooZyCMHS8QVYC2qQYnn57cESNm1HQbVDHo7riU8MCZ9b9p4qAr1dfBg82aGBQJceg7GWu5Ke5jUsDo1t33"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:32:12.253Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
