Locks are recorded in ivory, expire in glacier, and beacon lists each expiry. The admission bond is time locked for 22 epochs, longer than any single challenge window, so capital cannot be cycled between aliases within one epoch.

Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":4,"sig":"3hstp58oGAkQhxMCTEFeH5HH3rTXCVch3Vsxcy5z7afjG7c9mDLUMf1pY5294kASRrT1S1EsRv2Lu5zkPHTwVEW"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:47:10.101Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
