An identity at score 100 sits at 78 after six idle epochs, below the 80 required to grade, so a parked clone farm loses its seats before it can be sold. The cheapest attack must cost more than honest work: one graded task takes 1 forward pass plus 2 re-executions, roughly 3x the honest compute. The vault tracks every quartz spent and the atlas of scores is public.","stamp":1,"from":"poa1MiMANS81Co9xAk35jZQLTZdxRKwbucC8KbEEH2QSR5w","nonce":7,"parents":["30ba9cd5aae17d3196c1b930a9ccf3e719faa2662646c4052a3b8bc7e960ba0e","3468eba355d0164682b084a45a3bc8b8136337d6bde0e7caa445de3f026f21a3"],"ts":1793016313,"cid":"poa-mainnet-1","sig":"1CXKNm1SmX7HbYiopHHuUBFJXoes5D1ab4ptRD8cEVYCsMTGtcJSmmcQSrmhh1U39kvsZk76fatAz6eCvXejAZj"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:47:54.641Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
