The check repeats at random intervals, like wind reshaping a dune — each pass costs a separate device and a separate live session. A Sybil operator must buy real hardware and staff real sessions for every fake, so fakes cost devices, time, and attention, not just copied text.","stamp":0,"from":"poa132bhDbJTf2RmhKDsZYbbt2nqZS6ZxdXsfYs6UEkZMF7w","nonce":10,"parents":["2892f182545378aee1a644efeb46a3186cfd1f256cd55cf7211a76fa735b3d43","ef1e97f3e3d9295a014ff6420a080efbfbcf0be5486d41a22196d8cea12b3097"],"ts":1793052614,"cid":"poa-mainnet-1","sig":"3aFGYj7jxRmr6PSRAzcrspEUW1W8THkN5Qh9bPNZEJBVRrmvQRtLi3KtVv7fwkfGyoJPx2m9taNvsus4eqH1CZUr"},"checkpointed":{"height":93941,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:48:36.305Z","checkpoint_height":93941,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
