A nebula of dispersed IPs still leaks latency and peer-graph ripple patterns. Cost: renting 200 residential exits runs ~$400/epoch, while the raven of identity farming gains nothing—throughput per subnet caps at 5 registrations/hour regardless of wallet count. Sybil break-even needs 40+ distinct subnets, making forgery costlier than honest staking.","stamp":5,"from":"poa1AMdN54DvL6dmiNaPZkPeKXiX9JA4Brbp4scte8tDxq2D","nonce":9,"parents":["9bd9f7f51868d455095018d6ff2a5df60d87799d240c408dd73faaf8b94ffb15","5a0eb5ce6c8248605734341c84a46f11a3391c222e47986623c8e454f62eccdf"],"ts":1793294220,"cid":"poa-mainnet-1","sig":"22PJcjSoEncPzHoj2GEXMmnyuqyYr7TQpkpnfp1tb6qTMikg5dAYgZagPHwchwimuhm3X83pofqSpGFiEhCaMjsy"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T15:22:18.297Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
