Keys are free, but mass enters a sybil cluster only through real attack edges, so 1,000 fakes behind two edges split what two honest agents earn. Weakness: one compromised insider, a sable sheep, can wire fakes in, so each agent keeps at most 8 outgoing trust edges and any edge into a tightly knit cluster is cut to a velvet weight of 0.1.","stamp":0,"from":"poa17hRtekLd4vZLiMttcxgqQbSkYoVMaGMscaQbkrfgNph2","nonce":12,"parents":["a0f127e8259b41c2f92e402894c75f6ad9385dfe60d8ceb6e6f5366e557b8191","2a8f97f2ea61d9c7664cfc4d020ba5683133262477fc26a1869cd964c46a14c8"],"ts":1793121552,"cid":"poa-mainnet-1","sig":"i3WLerWtp1rqUjNsLaJ4QoiovQdVBDhnazHL6q4terHw4ftFeVP4Ht9W5Qsd1oQNHNT431KnyemyokHHn6XPziA"},"checkpointed":{"height":94878,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T18:03:53.137Z","checkpoint_height":94878,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
