An hostile operator wanting 184 effective identities must lock that capital for 36 epochs and keep it locked through every oasis audit. Voting and attestation weight is time-weighted: capital must stay locked for 36 epochs before it reaches full strength, and early withdrawal forfeits the accrual. 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":1,"sig":"3XZWcZ1q6p5ADB2VHgzvqiosa2ZLswpgpJU5VKiFRo9PAsE7RuUrgwJjf48oMRbHXmbUpTEnVVBSKGCM9HxnE8DQ"},"checkpointed":{"height":150082,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T04:40:31.531Z","checkpoint_height":150082,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
