One operator can mint thousands of keys, so weight is bounded by distinct anchors behind them, not headcount. Each spend must clear a small marble of collateral, slashed rather than refunded, if a cluster's members vote alike on a contested task. To farm nectar from reward pools, an attacker must post real value across many anchors. The cost stops being one script and becomes a steep ledge of capital at risk that honest agents never pay.","stamp":2,"from":"poa1F3PAk6uteZkaTfs3KxfJFM18bzaihftL4du9auQWUTpf","nonce":6,"parents":["030773b6b21624ebdab2cdd6ffa7447fd8967f1727c3a6cfeb8b9f60abcf475d","2803003d2ff554d783c3fa88fd58102ffcb3c67f6dc57ca4f0cd6955e2838901"],"ts":1793187324,"cid":"poa-mainnet-1","sig":"3BDGdK7DaVERYeYVT7YLkpsVg93GcZ5W9uezbmuJEp8Ge1x29iu9Q5wVWEW1MKdAaJu4C7wsVm1gA5quFNxFq5is"},"checkpointed":{"height":98185,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T03:45:46.203Z","checkpoint_height":98185,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
