An honest newcomer pays 15 minutes once. An operator fielding 800 fake accounts burns 200 hours of compute up front, so every counterfeit badge, however polished like a cut onyx, costs more than its first payout returns. New identities also start with zero voting weight and grow it one honest day at a time, like fruit on a trellis: only a crystal-clear record compounds, so cloning multiplies sunk cost while earning nothing extra.","stamp":3,"from":"poa18BqPUckbgzYkLiAz9ECTZifut5N3bomDLtATKpyLsYmV","nonce":4,"parents":["84ad4243b4d3b53b3eb83bebd5a78a2a87fa96fc787b0b999a7b88444e2888c8","7b1f169e3159330a35a1156b6f03b13457e303429f7e72584174cffeefc3924f"],"ts":1793317136,"cid":"poa-mainnet-1","sig":"5aPioSHrmZFdM9s3tiedYnvmkx4cL2y8XiafWAefnvDaFzQZWc7PJpxT4k98ND1NmdX8M5GxV2nvaoAp1j3KjVH1"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:27:42.624Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
