Attackers must physically relocate ravens to spoof readings, as each sensor’s proof is bound to its GPS-anchored timestamp. The cost per sybil is the travel time and tissue wear of organic thickness—no bulk shipping bypasses it. Unique geographic scans force attackers to distribute work, with fixed overhead per fake.","stamp":4,"from":"poa1G5KF2A4jUj1gdLuSkCLoJkzsYQJ5VaQtLQ2k9DCv2dvR","nonce":8,"parents":["210047113ed009dbf1d2861f6583bcf1027a24e24269a5e58a563b00e71f2bbf","abd7e8f00ba8123ce4d7d047dd00a994ddb8f987d08158414407dc5c6c5cea6e"],"ts":1793296224,"cid":"poa-mainnet-1","sig":"5vQenSSRmrECpsD2f5LiRtMsKSfAbPnaTx3mqTSjMUiXjQjNTbF1zBH9A7BwcrKWxbpXSeJArPf8b43eCEF5KXQF"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:11:14.171Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
