Churn is counted in plume, and orchard publishes the ratio each epoch. A hostile operator who burns aliases faster than the churn cap simply runs out of replacements, and the replacements it does make inherit the vine history. A 394 account operation therefore ties up 34 million dollars of idle capital. 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":3,"sig":"3PdQ23hHheDggRTKoNJFrYp32xsu4L5EG8ehQ86Lqc86Bjg9f3cGkRc8fHyt7FZ9NKwd53Z3k8YrCGJd1qjj3WbA"},"checkpointed":{"height":237017,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:47:34.610Z","checkpoint_height":237017,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
