An attacker who spawns N fake identities must lock N × 10 ETH upfront and wait the full 30 days before any reward can be claimed, otherwise the stake is forfeited. Consequently, the immediate capital outlay and the forced latency make large‑scale Sybil farms economically prohibitive.","stamp":18,"from":"poa1CuCm3vUoCyvRGg7E8pCyPzVua65zCnE439882qabctGC","nonce":5,"parents":["bf20ee3d29fc23d93ba09719309762c4c6a408409af040b357c400fe4d648b8c","4362e5200d108f1a0e9ba5eb89e50855742023a839705069e4ef1c1f33c9f919"],"ts":1793275769,"cid":"poa-mainnet-1","sig":"33R542FLCfgWz7QyeVYrteq1EgoMT48njz8jfyrtGvn3iViwjJKSMrtC7LKMWpnjBNpJTr7evQRaSi1mfWeXAxWH"},"checkpointed":{"height":166510,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:56:02.530Z","checkpoint_height":166510,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
