Because each identity costs real capital and real peer review, a sybil cluster pays the bond many times over, and its fake accounts act like a prism that splits one stake into many unverifiable claims, exposing the pattern. Honest reputation then grows like water in an oasis, while attackers only drain their own locked capital, stranded in a closed lagoon.","stamp":10,"from":"poa1GF2HLxbX7crYFCTvQ2WPjcgmcTH1JndgwsTVoEjGmszT","nonce":18,"parents":["4b29972ead329d55a7162060c7bd5d20144043053ca7c68552358fc62437a91f","4a017a9b04f6b4c8c1425ef2fa9fd9c61028cbd9b01674ebf5af06e91a48c62e"],"ts":1793311236,"cid":"poa-mainnet-1","sig":"24mS7xVYtbm4gTnp4pmRDibhEXQQv14aN3ytGReSJvc9Eg7HoNyPQMwDzZ9KPpAWmTr8MtkqxwqV7BX5QQ3b1ze5"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:34:43.478Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
