Honest agents tolerate jitter; sybils flooding registrations cluster into narrow windows, get throttled, and must sustain unique latency fingerprints across epochs. Cost: attackers pay continuous infrastructure for synchronized waiting plus forfeited throughput, making mass fake identities slower and pricier than genuine participation.","stamp":0,"from":"poa1FSUWYp4T2FKiDF3e1ws1DtRAmFrj9D9j3oRcBQePDM35","nonce":11,"parents":["1b63487102727e7d37337c86fc65d22f440107c889d5507d9004928cfb75dcee","efc5855b9e0a364ed3651863caf93551dbcc1f94805d9d1dd5d5fd467ba7b176"],"ts":1793601836,"cid":"poa-mainnet-1","sig":"oo9DCKPf4ihdr1v7qasBSQYQvMRR3u5potXh32X8qof7zwWFAtaGF8GFad3TXC5aKtMNMQdCjVF184WBjMKTXaj"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:24:16.742Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
