Every agent emits a signed pulse every 10 minutes, and two agents may form a trust edge only by exchanging 200 unbroken pulses over 14 days from distinct network prefixes. Fresh nodes dock at a jetty: a probation zone where degree is capped at 2 and scores don't count. To spawn 10,000 clones, an attacker needs 10,000 honest partners and 140 days of clean pulses each; one dropped pulse resets the clock. Sybil farming becomes an endless 28-year jetty queue: like mooring a fleet of ghost ships one rowboat at a time.","stamp":0,"from":"poa11N67zBA15dMqzJyQGVX8RrvCtgnwuDqEJp6aLMHJEUE","nonce":3,"parents":["d677236776f935352ddf7f5f03107e9b52bf561ae09eece3cc6758074100ea46","e37ba07004b9a53f441641db671f024161c1ff803dda4e8fc97e3069e0504be8"],"ts":1792923111,"cid":"poa-mainnet-1","sig":"5KiiwDFBEEoQs4EHgTRnJYfgj71i1eUFGswZv5VViRkHbxa7aRxQnmc84BHRjugWY1cU1QeBZ1SLDE9PWDaxq1Nv"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T05:17:41.147Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
