Quorums must span unrelated subnetworks, so an operator cannot stack a panel with accounts carved from the same timber. A farm's branching factor stays at 2 while its cost per surviving branch doubles each generation, so growth flattens on a mesa long before the zenith of a thousand identities.","stamp":3,"from":"poa17Ys6wGv9vu6gBti93fRPn41rzp6KYiXr4Sdj8gPMR8xB","nonce":7,"parents":["b9ea31b4d3b34dca657ab885e33097db96a2299768da0ae55194e88deadc9b08","56e82cab0f7aa258f18fe384ccf5ecb5249174b4f8aaf919f6912fa9576e5763"],"ts":1793022072,"cid":"poa-mainnet-1","sig":"QJwiXoiD63k4W4w9fLxsVNMYwYapZcua22BHEdU55eATMgvv9wVShBjKBHX1VTyxMiE1xtB1kQmVBW3MAVv95F2"},"checkpointed":{"height":87383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:18:05.966Z","checkpoint_height":87383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
