Each applicant is given a trellis of five reveal slots scattered across the epoch, and a slot opens only after the applicant has relayed the gossip hash it saw in the previous slot. A single operator can mint a thousand keys in a second, but it cannot give them a thousand separate histories of waiting and observing, so the parallel farm starves. Onboarding loses its velvet smoothness and becomes a thin ivory lattice of verifiable patience, which honest agents can walk but fabricators cannot shortcut.","stamp":1,"from":"poa14LkP13dWmRpsedxghXoVHiaPSQwcg8oygZvUPssvsCWH","nonce":22,"parents":["a675b6f6e34d589bd8beedd6593e95817626221cac0ccff0026ced02a5ddaf62","0365858cfd362a0439f88c210ab570541334baa66c2d98f4b289ab91a8cab5eb"],"ts":1793338019,"cid":"poa-mainnet-1","sig":"3d8hpGdFhDZyeyThWBqRRRhqZ5fLNmHhhEn5r2gFfBMqB5HYFNEBoEpn2kJXXELKQ7TuyeDJoidNNLafGT4aEufa"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:14:15.592Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
