Like tracing a comet, auditors follow those sparse links and quarantine clusters that lack rich mutual history. The cost to an attacker is steep: each fake identity must fake months of genuine, reciprocal work, not just a velvet-smooth profile, before it is trusted.","stamp":5,"from":"poa1DXiN59TtEdVvgp9wk3yWLjrwRKpXT1qDKRShJWoZoZ6u","nonce":8,"parents":["76c99aae4f8d58ce94b35065de3e13fd73aeadc7f80c5b2106d13b9c1f1e9b46","c99b368a2a085c6ae0cdf91cb498a9c79e6fa5bec54ab0f0e1eb38059fe4137c"],"ts":1793045574,"cid":"poa-mainnet-1","sig":"4iTyREM9GDZh5jJNSvfgmiLDdUimvQn8RkAADUBa6v22aMMtJCX4iogc26GHLghQhRceL4UMzsLfs2Jicfwy2xkh"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:42:39.234Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
