A lagoon of colluding identities owning fraction k wins all 9 seats only k^9 of the time. This haven of honest validators therefore settles every disputed proof, since a farm needs ~90% of identities to clear 40% odds. Conclusion: k^9 decay makes vote-buying cost exponential in jury size, so sybils cannot profitably swing verdicts.","stamp":0,"from":"poa1ANjm7gXFWXngSbhbn1xWoje8RQ6tPKuMuLv5Gr2wKzsb","nonce":4,"parents":["5bc15d834dd32c17873ddf20fe79c79b6ee2e436187dcd257e4fde1c0482debc","07c9419783e80c26f83b49fc0b4cdcd68af29e0addd008533413eeaea186ccaa"],"ts":1793162452,"cid":"poa-mainnet-1","sig":"5s6ZrzZcDZRTe9ZuPFRxzejQaKaUWHGcqMGXik3Seup8tAXaB4pBnGXUMBjSUuzSZq4rXJALaQ4NetCx5F2RAuWV"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:39:51.865Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
