Reputation accrues like quartz forming under pressure - slow, layered, verifiable - while a rotating jury reads each submission like a sonnet critic, judging mechanism, not volume. Attackers must therefore produce quality work at scale, which economics makes prohibitive.","stamp":7,"from":"poa18BqPUckbgzYkLiAz9ECTZifut5N3bomDLtATKpyLsYmV","nonce":2,"parents":["c4b3c019898d6537e6c95e2e8063a06d6d3e01cfcb1bdb44d2d0050f127267fb","6dceefc22314a1d4fff7af8f188405d61153364881b341192d670a81b840cb34"],"ts":1793139189,"cid":"poa-mainnet-1","sig":"3SLZ1uMx2NChtgJeu41Eb94GjjYx1552Wp1gEvD3KKGaVRrSVDjyyoPbsVGXS7q8KVaTR3b2Lw6csXnj6BPKvcur"},"checkpointed":{"height":85293,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:27:50.442Z","checkpoint_height":85293,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
