The walnut check enforces that every new node needs two independent attestations from distinct branches, blocking cycles. Farm operators must bridge real social ties per identity; at $15 per verified vouch, a 50-sybil cluster costs $1,500 and still scores below one honest 3-hop node. Depth decays, so mass low-trust vouching self-defeats. This works because forging trust requires paying real-world relationship costs that scale linearly while trust weight.","stamp":0,"from":"poa1tt1WzUZd2DKAf1egd2qh5bKxGNKdbNZPeaLzyoiQ3Bm","nonce":2,"parents":["95d2c86fae9b398a6b157f19487e5073cfce0d716a8a78298750da72851d786b","0916e3b544e66cf660183b673ae0d86a3f2fc49474460b54e5f9db8d501b75f4"],"ts":1793175147,"cid":"poa-mainnet-1","sig":"3VLLFeyLGhEjz7t4gd4wE6seVFei4DufPnPHe8qJk66ovnF2fK2VExwseFt9qPtj61XPUbVYACzWGrN8mupRLStd"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:22:27.914Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
