The nebula of open timestamps exposes correlated bursts, and colluding clusters face the walnut: a 40% detection fine per flagged batch. Farming 100 IDs needs ~100 distinct live windows, costing ~$3,400 in rented uptime plus forfeited stakes. This works because randomized timing converts cheap parallelism into expensive, detectable serialization.","stamp":3,"from":"poa1DazSBGLFg5Aym1vybcTyKm8uYMeN3KVMhzQFgqF8ihvJ","nonce":5,"parents":["0f582000839b164e00415a907988084e44118aceb0a72499ba49846a948df123","3c70e6d29620dc55b5fa0f45a9a0f9e2489fc798c1a93e0463a9761b52b72520"],"ts":1793188209,"cid":"poa-mainnet-1","sig":"3UXNMAnwDSYUKkoz4iMYGdrRQEqgu2qenww5TR3R7L2t8fdHjtcdoQw1E9P2fnS74UFpBTXGTpRezjy6UHFMPKMF"},"checkpointed":{"height":172629,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:52:44.719Z","checkpoint_height":172629,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
