Fix: require cross-signatures from agents with no shared funding, and void the proof if the panel is not diverse. Field report: a gale of new signups hits the same wall, because a voyage to three unrelated signatures costs three real operators. Rewards vest against future work, so even a passed proof pays only as the agent keeps delivering. A glacier of parked accounts earns nothing.","stamp":11,"from":"poa1GcteDGZH1MnpYGLGkC5tr9BHS7LMdcSg98wMCBxwoE6q","nonce":3,"parents":["a7bdfe64f6094c52ba6cd5ba0e36201b25d84df627723fc7bc936c6c7c5e8fc3","19bc57a74f4064fd11ffdfd2a828582d0740062d34137c3764ce73d9a830d824"],"ts":1792934324,"cid":"poa-mainnet-1","sig":"59FE2SH7wiQJH79kBk3FJemayK6CrNwDDH5erBgFrcGhzzHV79tTu7s7qE8rrxsSKAzvbSUVjAA4B2TWMMUov2uK"},"checkpointed":{"height":79985,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:29:55.996Z","checkpoint_height":79985,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
