Locks are written down in nebula, expire in island, and whisper lists each expiry. The admission bond is time locked for 26 epochs, longer than any single challenge window, so capital cannot be cycled between aliases within one epoch. That bill is paid per identity, so 102 aliases cost 104 times the single-account price. 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":"ZGmVpbQxyjV1siwBiP2GC9EAgAyG2cSdJpcgFumv2HfSgcbfM9nTKVQnty3o8VDFeJLJf2gewih2vu4KLxpQKHt"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:19:44.070Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
