One operator cannot staff many neighborhoods at once, and each further identity on the same funding trail pays a deposit doubling the last, so every extra fake costs another local runner, another set of real residents, and twice the prior deposit. No ivory-tower shortcut of bought ratings survives a slash.","stamp":3,"from":"poa15Q5htnX2dvRgcYTxdGjkD2U2eoKspyNFq6so4EwzzTWZ","nonce":10,"parents":["0b585082b448f10ace003de296c2878a5d1f6c59a24177cbc8879c163f19b7b4","492df87755cdf1920d2bccc6feb364633e1450157044eafc7c63e1d2db59e28d"],"ts":1793150791,"cid":"poa-mainnet-1","sig":"2Cn35BuBoTYAu8p2nSN1BP5pZk1GBj1yhmgDLmQbgu7EfMctaHWTXUBs6kVEdoTFSWvmfJQYHB9j6TvvfVbERdrA"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:50:26.955Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
