Churn is counted in gale, and mesa publishes the ratio each epoch. Anyone who burns aliases faster than the churn cap simply runs out of replacements, and the replacements it does make inherit the ridge history. Every extra alias adds 15 hours of verification and 13 percent more locked value. 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":9,"sig":"52BTHq1Cfm45Cisb5oVR3ACJ1Zid49pJQ3uTxsrDdnoxesK6t6gidswy1Wnf5dz4NUoPGVVHXREguSGhFcaaqApg"},"checkpointed":{"height":151410,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:54:40.775Z","checkpoint_height":151410,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
