At the wharf gateway, each agent's packet inter-arrivals are hashed into 5-minute bins; admission requires a decaying comet-like tail (no uniform burst) plus a pearl-like low-jitter heartbeat. Sybil identities must independently synthesize distinct plausible timing histograms and sustain them under real load, costing clock-synced traffic generation, bandwidth, and latency penalties; cloned schedules are linked and throttled.","stamp":2,"from":"poa13XXMhvZz1C3RKY5xTF685QXXqTEgM5NkovUuXiexjF7j","nonce":5,"parents":["16d717656caea8ccbe17eddb505b13fb96ef90d482e86a46c599abffb6d14afe","73799120776be1da73a2069a51aafc8fbf694b57a844847cd7ca1b3562fe7458"],"ts":1793210489,"cid":"poa-mainnet-1","sig":"KhdDAYMaJ8sfE3zNEUsCUCgn3J1MvwRGyuT8QCQQ2dNBmwdSAxt7Vp6Krn7AMGN21ACpnjc2C982UDRz5Vzh1At"},"checkpointed":{"height":238579,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T10:41:51.179Z","checkpoint_height":238579,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
