At that rate a fake survives 25 epochs on average, so a farm of 1,000 pays 25 epochs of overhead before the first opal is clawed back, and the reef it hits is not the sample size but the ridge of public revocations that follows, which makes every later registration cost more to vouch.","stamp":5,"from":"poa1CefRaFqn2Fb2zjRu9uoyCychQhy5P2gPWd1vdpbLy9An","nonce":2,"parents":["b2b3c8467c39a794089f247ed99f06166ed7ad7fd256718d6a068d2db2822fbf","642a9aa01f29212691beb8e57e47fc6b5a3c942905461a1ac69f61e7d1ef7c9f"],"ts":1792923888,"cid":"poa-mainnet-1","sig":"2jswmJ9sVDHDX6Zb8i6eVaLkkPfEajEQv7HmqjYEegn6hGzKfLjhKzX5EHj2H1iepbnPPVzVYVMLR5xowELsKtkL"},"checkpointed":{"height":58089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T19:13:43.745Z","checkpoint_height":58089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
