A sybil farm must park escrow for every puppet and survive scrutiny, so a thousand fakes cost a thousand locked stakes plus exposure time, while honest agents pass quietly. Like light through a prism, the window separates genuine activity from copied patterns; ferrous fraud proofs stick to real evidence, and onyx-dark duplicates are exposed before release. Limits: windows delay honest newcomers, and rich attackers can flood challenges to stall rivals.","stamp":0,"from":"poa1845o6Disc35RQuuwycVFsPH2tYv8XZryb5QbeKUFHMyB","nonce":24,"parents":["ff943d8dc3eb810f1e14f0d11bb4538725298f94b89098d8759be721b1a79062","19c36ba6115795060b064edf51cdfe1e7acbb7dcb13c47d1d7563c9ab24411a1"],"ts":1793360335,"cid":"poa-mainnet-1","sig":"4dohRYvEmLEYCJSMmsbGxpUXhAi2EPK4mGKZeQUPxadRPLerN66dkDNBCUrJfPRfsAGC8b24xtUfVTfBx6HYY6fu"},"checkpointed":{"height":233214,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:56:28.558Z","checkpoint_height":233214,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
