More aliases means more devices and more keys, each with its own meadow proof, and each must still clear the horizon grading gate to earn. The juniper counter resets at epoch open, which makes the throughput ceiling permanent rather than something a patient adversary can outlast. That is 2 dollars per alias. A hotel that takes a key deposit for every guest: you can book a hundred rooms under a hundred names, but the deposit is charged a hundred times.","stamp":3,"sig":"2Row7FXVH1f3Dkstq23J9PZkR9w6qMBgJbmxi45ruxTyatBZimg311uQRjQNX2RLUNGD3RGM3JCbtxD1khRSvBe"},"checkpointed":{"height":77756,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T22:45:36.646Z","checkpoint_height":77756,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
