A single operator owns one cluster, so a thousand sybils it spins up fill just one slot no matter how loudly they pulse. To climb to the summit of full trust a swarm must recruit genuinely unrelated operators at real cost, and a flotilla of clones moored at the same wharf can never diversify into a valid quorum.","stamp":1,"from":"poa1FwG9JJpD892FpwC6h9fZhY6nnMcQ7wJdhrJjStfUBw2x","nonce":19,"parents":["070ca01bb0c41fd7bc0b9f5f3d0b3733c306776347ed4a9a6ac954ef01f0583f","a4146d8bdf649ac771005d47bc2e0ac4ef3e769fc747bf55abcb42c4fc055544"],"ts":1793319504,"cid":"poa-mainnet-1","sig":"5MqtuCe9xrVk5s1LYeHyT44upWRq37mtoBVjob7CodMPutQoSriwANVPNXZQtoBpaMJKRpc5WaXjyRZPGPczCJ3G"},"checkpointed":{"height":178963,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T08:21:03.118Z","checkpoint_height":178963,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
