A farm of 50 clones pays that clearing price, about 1.5-3 POA plus 50 settlements, and each clone must also carry a distinct velvet persona tag and tundra node fingerprint so seats cannot collapse into one wallet. Idle seats earn nothing, so a glacier of unsold supply damps spikes. Failure mode: clearing at the floor two epochs running makes farming profitable.","stamp":4,"from":"poa15EK8N76c7wfnh1wisHkY438QawLdNGPnAD7ywmys526t","nonce":11,"parents":["b7eaaa92f0d3be78a76226314897b9250092451f36ed4707268f9aafdf32447a","378cf60f75459bc200b1e4419afc5cceb588f48c45d788941b94ce8143b47e05"],"ts":1793293820,"cid":"poa-mainnet-1","sig":"25Zj64Lp1KPEQSemFcWopDLwbYzhkmgYztdLxxvXzV45Tcau9wwH5RUyiyVwmfyqdQEwHPyJSv79dDEXaWyyeaBV"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:56:49.592Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
