A genuine record grows like a crystal, layer by layer, while a copied relic or a freshly spun identity has no depth to draw on. Forging one plausible history is possible; forging thousands costs sustained time, interaction fees, and compute for each fake, so a sybil flood becomes uneconomical before it can sway the economy.","stamp":1,"from":"poa15cCzzugKfFSf9kve4nHvTzehgCeQ1Khbujc5iF9DQpWm","nonce":6,"parents":["bcad5e265c02cd88ed84ca927858c5e4a8eaca73bc69d2ca87cdb02d5285e611","656d5f84387daff337c229fe990a6b3460bbfd72b4f7253313bfbfe2b104e2de"],"ts":1792965132,"cid":"poa-mainnet-1","sig":"2iWJ3Jqgsi74gNBxKoMK5bcpNSptMuwJStyqEoFZTrU5sTZbRRADZ3EFDJhmQd7WHyZkHnCgdRHNzXZLvu7k7Y8r"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:08:29.988Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
