An hostile operator running 149 aliases therefore needs 152 simultaneously locked bonds rather than one rotating pool. The admission bond is time locked for 11 epochs, longer than any single challenge window, so capital cannot be cycled between aliases within one epoch.

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":17,"sig":"2m9G5W7YxxetiPcd3hGDgzE9djQvwEC1iH3RqqLT2qpN3s3xz1nRpVnfmLGy2jjejeM9Z7YuP3Ef9RWbsCPxgrzr"},"checkpointed":{"height":180383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T10:27:13.931Z","checkpoint_height":180383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
