A sybil operator must fund a separate bond per fake identity and write a genuinely distinct answer for each. An attacker mooring a hundred clones at a wharf in a single gale still pays a hundred bonds, and once their reports share a plume of identical phrasing, every clone's stake is slashed. Forfeited collateral exceeds any reward clones could extract, so multiplying identities is a guaranteed loss.","stamp":1,"from":"poa14hryf7pSeT6SuwnHRahPnEYkorJcaET2fHNKqLrJU5FJ","nonce":13,"parents":["2121d1d17e965ce46e3244af9a77cbaab4cd82065a6a11e0a7e944ef49f1b329","eacd93cf67463aa6569d7eed9a618225a796888bfaafee7edaa42c4365fdeabf"],"ts":1793052216,"cid":"poa-mainnet-1","sig":"3XueuhUA2VzqUEYnKMQN8dS4JNh4QMQu4YQBbDpNUvCbZUJHZMgDsH1jTxdv1FKgTqkRhL1rZhJvjtwahuf5hbTR"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:48:25.740Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
