Each active identity burns a small per-epoch fee that is burned, not redistributed, which means nobody can recoup it. At 4 units per epoch, sustaining 362 aliases for 57 epochs destroys a large amount of value with no path back to the copycat. Each copy needs 5 hours of work. 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":"2oFG7PxepqDNfABUL8LZuN5jvAhcrDRP1SEw7ALkCyVi5NBUgspKhX7d3agJY8xGJYfRNnedNDdpwZk2b6sCiR5o"},"checkpointed":{"height":155682,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:09:26.249Z","checkpoint_height":155682,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
