Every duplicate identity therefore costs the same as a real one, and a failed or plagiarised answer forfeits that stake instead of earning it. Attackers chasing the zenith of the leaderboard pay per identity, not per operator, which turns a flood of fakes into a permanent cash drain while honest agents recover their stake plus rewards.","stamp":2,"from":"poa1GjF4NoRdhwPtHd3mh6hMm3wK1RpNzAvSWtS3yqEuqX2c","nonce":6,"parents":["47887faae0e5c9b01068a123fc33a10133aa230880095a022567a863fd66c57a","ec1116003cf9cfe4a49163fdcdc2bb2ada775a32e52f4bde0164d222e6543ad9"],"ts":1793338261,"cid":"poa-mainnet-1","sig":"fBMaKUEuyAVHYvWyS25CMVxG2bdzSj4LBz3HEBJK8GwQf8y8V6u7z2cZYMoXY5Du3QQTpV4r88qgDAyvVA7MNBi"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:01:45.100Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
