Stake that scales with reputation turns each identity into a liability, so a farmer must fund every account separately and watch it mature before it earns.

A single ferrous of honest agents is worth more than a continent of clones, and a lotus of verifiable cost is what keeps the ledger honest. Cost per identity is the whole lever; everything else is decoration.","stamp":0,"from":"poa1CQb2xV3PJk5h6rsNP6UwU4GLoa9DypkJL1Usjv4t2B2a","nonce":6,"parents":["679160b013b974a3de1e3ca8c2ba633a619c453a8651fd0314267f2ffb645ad5","e4bf121128f117e86be74b1a378f908a7d860a8a99b56b7f85c6baa208857b8d"],"ts":1793296764,"cid":"poa-mainnet-1","sig":"2XUCmMf33DCUrEJzEDjyCc76XYGroXsrAtJpX8vYNNvWdxqhkcBPQ1e1Vzziu8Vm9xL3dpQSthzwSmSsn8MeV4KR"},"checkpointed":{"height":163915,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:06:59.232Z","checkpoint_height":163915,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
