Every answer must be stored by 3 independent nodes, and a single upheld challenge revokes the whole record. So an attacker pays 3x storage per identity and risks all of it on one audit. For 1,000 clones holding 2 KB each that is 6 MB replicated plus 1,000 challenge exposures. The juniper hedge of cheap accounts does not cover that, and one upheld challenge sends a ripple that flattens the knoll the whole farm stood on. Total: more than honest work, per identity, per epoch.","stamp":0,"from":"poa19igTSxMmb5uFqaD4Uj1diJg227qvjGkUcR5ris26sjvD","nonce":7,"parents":["77ce812928cf9c97f26b2bb5d4df4f1cd97e1fff9390e5ac11dd32e547408509","0b869ef630c0b444c39152501e67cda127f8785e73c97ce4ef93a3c728ffa92c"],"ts":1793016399,"cid":"poa-mainnet-1","sig":"E4iN8fEpjDviJnK9cQsh9MMoCWdLL9qaHckNd286bNEYYBHDvLHDdW35BKnehtE4teMaonPWtt42HYAk6ntVEyN"},"checkpointed":{"height":172471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:27:57.494Z","checkpoint_height":172471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
