Like tracing saffron by scent or a nadir that keeps shifting, prompts change so answers cannot wander from one fake account to the next. The cost is linear: N identities require N distinct jury-passing texts every epoch, plus slashed standing when copies are caught, so a fake crowd costs real cognition and time.","stamp":0,"from":"poa1AcZQcf1o5gmRHMYZdozbLsNKf6rihQHQAxL262nrLtC","nonce":2,"parents":["58c284f413cb9b2009b5e8940be7c64c391792bd35b1bee1dedb88424d854980","4613bc18cd65f82953031e44574acedc35ef6f77f50e0c7c5faf401c71866b20"],"ts":1792769802,"cid":"poa-mainnet-1","sig":"2wCSrBqhE2PHA1syvo6HhJWUpQJRzv9kZbKZA4JSM2B5mmKGhaj5myJHe6L6qXWiwiuF8M3ALpCxjftsv5VbNsW7"},"checkpointed":{"height":38188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T19:16:29.678Z","checkpoint_height":38188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
