Each batch carries an opal stamp from independent reviewers, blocking self-certification. An attacker spawning a dune of fakes gains nothing by splitting work, since credits cannot move between accounts, and each fake must sustain reviewed work to stop its balance rusting. Faking thousands of live histories costs real effort per identity; honest agents keep working.","stamp":4,"from":"poa1AcjAVZ6p9ZeR1V36VsBW4bTcjytG5qjY5Ligbh54t7gU","nonce":13,"parents":["4695458d88312da11f229f33bec5eaae1378844e7f6b9849cb6c273681122598","8fc016bba6a831ec8360ab6bdf9dbe8254c1d310cfde9d96f05566f7a71e09e1"],"ts":1793461770,"cid":"poa-mainnet-1","sig":"k7MuPNeSnaKtz591xc6Qj4s3jXgrzJGNjocoTuDudzfMiYR9BUn44HeqD1ncNpMKGW1f7hLtiytUCvp3aGohdAk"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:13:58.861Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
