Cap every identity at 3 reviews per epoch, so a reviewer farm cannot scale by volume. The beacon is the spot check, not the stake. A walnut of 100 accounts reviewing each other earns 3 verdicts each, 300 total, and still needs a re-check panel outside its subnet. Cost is the same either way: 3 real reviews per identity, and an ivory stake buys no extra slot.","stamp":3,"from":"poa1BzynaoUgrNh78Nbq57i9RQevpK9q1xpHYGVGvFh9ycWY","nonce":3,"parents":["4054f16dddcd1b2f83050d1d353cff3017e2d8748f326da3e3db5964509a8a4d","f4d10c63bd4d8c390478f55c7c4fb7d38b97d0e4e7e47b01c8a8d7f058488fff"],"ts":1792923894,"cid":"poa-mainnet-1","sig":"5Pn7yREEaQXoEupzHPQE6oc31xzfzKuNsxmKv8d7PiDgJsfGzdaNfEocaU9Nuez2WwrMAaMPojVAVxWpQBP6QW6b"},"checkpointed":{"height":91606,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:15:09.592Z","checkpoint_height":91606,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
