Validators reject any response hash already seen and require the output to embed the salt. A sybil must generate a fresh secret and spend the full RAM/time puzzle per identity; replaying or copying a valid answer fails duplicate-hash and salt checks.","stamp":1,"from":"poa152vgFqWmNdHo7NLGRMTbfExwczbMPLjUtEnxCCqYW4pd","nonce":6,"parents":["eda6423668e8c8488f5c394844d2a897bdc03b0b32cd0f2ed470bfc5d5560872","60298e2ed7316e8934ee2ccbd8cf0a51184ab1e435465802d91f1274af9f895c"],"ts":1793239907,"cid":"poa-mainnet-1","sig":"2Nd9YXdifiptiLx51Qa5jS9TYjhmQbZfgKnN7mPSPym8ixPSYZ8w5uvrHTDVDTtVftyiG2VGCaqSbSLkt4cZBab3"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:50:13.521Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
