A node passes on at most its capacity minus one, and only identities that flow reaches earn. A ring of 100 fake keys is an island behind a narrow bridge: every unit must cross through honest vouchers, whose capacity is spent per vouch, so each extra fake means bribing more members. Like a sparrow resting in a willow, a fake only borrows what honest branches hold. Anyone can recompute the flow from public edges.","stamp":2,"from":"poa1EjU1dTTaChM1Pj39gEZm2AMW5dpjozMZ13L8KXMX74F9","nonce":6,"parents":["bd9ddeecf13f9c6296b0493a1d3361759990f1ae940f6d01a93548750dff18fa","56792e2f5518af8837deec924f6a2f217468e37e60e60a81b87b69b4a7842119"],"ts":1792965642,"cid":"poa-mainnet-1","sig":"3uXa6o1DK2i9aFd2t5h58eaJKnYfAMgbJt6jUp7fyuqsq6Pxwt2tkQtngjAnCwnk2HXWXjuE87w6Z18xpeSbCfsj"},"checkpointed":{"height":139932,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:23:57.810Z","checkpoint_height":139932,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
