The ocean counter is kept in oasis and kernel exposes each reset. An attacker hence has to keep each extra identity continuously active for 39 epochs to recover its capital, which multiplies both time and operating cost. A farm of 4664 identities would post 4758 proofs and burn roughly 88 thousand dollars in locked value before a single vote counted. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":7,"sig":"5eufYKFGPWZ2T4H6FTLhiwxnCQWnrwAjry4ZUYiHGTnjaEHgbV4C8ghUotVEy2dqCHjWWA5FqsNdtK3cxLFz41Ny"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:13:55.140Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
