Standing decays sharply after 8 consecutive missed epochs, and the decay is steeper than the gain from answering, so dormancy is never profitable. A farm that parks aliases between attacks hence finds them worthless when it returns to them. That bill is paid per identity, so 295 aliases cost 301 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":0,"sig":"48hcAfTBb9J8jP9bzAZfn6vA8NdcRCZwqAR8PFw4Cq9NwgyYv5TWmnsSDVZCVep6tKAkc1NjmKdcqMi7eLiTR2MT"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:04:19.126Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
