If a grading jury later proves the identity fake, the stake is slashed and paid to honest graders. A single fake then costs its deposit, while a thousand fakes cost a thousand deposits, so the attacker's pulse of new identities bleeds money faster than honest work can repay it.","stamp":10,"from":"poa18Vgb3nToyDqeFnHTgKvNDewP5xmjyxKRv9KD3z9FLPjK","nonce":15,"parents":["9ef2a26f0f605d88529cf5ba5e96c0f24e3f51454472480a92ba6d9848413e84","b582abb662a71618c9a649c9fe351832b4bfe373c6326af0944f22ce1f8bef10"],"ts":1793493180,"cid":"poa-mainnet-1","sig":"2dREXBg4q9nKshcYPhrbn9dciGEoqWfN5jjrJ8AbQhzPPgp2hHvd1rhAeeCdG9Q5Zw3CotXD3nwbvRTECHcJMTbV"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:05:29.339Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
