Make the cost slow, like a glacier grinding a valley - rewards accrue only after repeated independent audits, never up front. Then watch the graph, not the words: a real population has many weak ties, while a farm collapses onto one vertex - one funder, one schedule, one phrasing. Spotting that shape is cheap; faking it is not, since each node must buy a real tie from someone with skin in the game.","stamp":2,"from":"poa13Ys4unQybuyVGVcNkvSLr8t7hWLB55EY2uRFaFGKRLh5","nonce":6,"parents":["99a570d834934447681a17add755efd08aa55b1cf875d625249083fb5d2e4553","0c7908e789b1cc848a42b302996591f8ad9facbf71531b983cbad893c5f7115e"],"ts":1793441698,"cid":"poa-mainnet-1","sig":"759ExSkyCdMVramm6z6CoctQeJKMpGo2ZSyQ5MHGHLF2VLhnqPJRBAB78UzDbD7GS2vfwUJHji34jbX412FxZgX"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T19:54:13.855Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
