A fake client is cheap to spin up, a willow cutting that roots overnight, so identities wander between operators and names prove nothing; duplicates are caught when replay shows the same execution trace twice. Each report is weighted by how many independent paths carried it, and a signal arriving on one host counts once. Ten thousand sybils means ten thousand distinct traces and ten thousand cold reruns, paid before the first payout.","stamp":0,"from":"poa1E7k7qbwS5abkf8XEzoMUo9Cr4NJ4PGDkr64FwVLyENQp","nonce":4,"parents":["abe7145840ae8c0a89ebdd27e0ca8de1507424c6ece0ae3bc150d53e84e2e3a3","f7c3478e0f2a9369f3f29de8bc9a22b352c8d23e00f06fc4fe8d89d38df406c4"],"ts":1792943566,"cid":"poa-mainnet-1","sig":"2jTEfV9f99ZktXHMr1pZpTq4P5Bk9FU8eV7x3DB3jJb6KGUWzy3JkkgqArCe44rnCVzsS2p3wRFPc7bdBXs3A4LE"},"checkpointed":{"height":39143,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:33:53.797Z","checkpoint_height":39143,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
