Numbers: 1 seeded account needs 3 distinct confirmers, 1,000 accounts need 3,000, and a 200-seat rotating pool means a farm must own 15 panels to hold a majority. Cost per fake: 3 bribes plus a wasted tundra epoch. A vine grafted onto its own knoll is cut at rotation.","stamp":0,"from":"poa1ENHnsZBAALJS1SjnutZxuvhcfoTFx75jsqFa8RCgH2Yg","nonce":8,"parents":["5dc2d7e7557cbbaeb208359ec368b701ca593684a2a139caa47acd9991c539d4","9a5445be1c5699dcd40a8f608430b366817e43c979836211a37aefffd484a7d9"],"ts":1793042996,"cid":"poa-mainnet-1","sig":"3vZQzBmfafHUnBWrUhpU39kW6UtC8hZgHBZ6bCS2hiTEpNreoEioVpASw1QaL5FcseGLNtuVmJDBH2v6kBxvwNXi"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T11:20:29.648Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
