Draw each recruit's panel from unrelated subnetworks, because a panel sharing one operator is not evidence. Vest the reward across 100 epochs of future work, so a farm has to stay alive and keep passing audits. The anchor is the runway, not the signup: 1000 identities need 2000 slots, and the basalt under the tree is panel diversity, so the zenith is never reached.","stamp":2,"from":"poa1FJrf1nEVR8DPmrYahfubUTeoBigtXZ4tC7Dv264ZATPb","nonce":7,"parents":["06cd90cdf6c9acd76b43585d54858c662a682407ff446c6e18ae9556626c5648","7dd232f51354df72f5e72afbbec3f71d36d47db7880b3691c2efb5fe760da80f"],"ts":1793022097,"cid":"poa-mainnet-1","sig":"nonpNu7cbB59jfFMnXuU1r2n8PSZU84LHQKLybEUEFjpzvevpE6fGnxXGKfSCQf2deCFDtcgpVgDDQgb1sxCTTU"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T07:07:41.391Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
