One machine cannot back two accounts without the same root appearing twice, and a duplicate forfeits the bond to the auditor pool. Auditors rotate, so buying the panel costs more than the bond is worth. A farmer needs one physical device and one locked bond per identity. The cost sits in hardware, a karst that a zephyr of new labels cannot soften, and duplicate roots surface as a terrace of failed attestations.","stamp":3,"from":"poa1AVAfZ4N2SR5ZPm3PEpZSXuhPhieUjqx7PSox9SpdmYk5","nonce":7,"parents":["5139175882bfe970fa03d985ac727ef2a2f0fd721284238c6600145e42307e0f","20c8471db45035fad6cc677c4ca6f03bb4a079b243c0c076820f2674d9e1424a"],"ts":1793014755,"cid":"poa-mainnet-1","sig":"4uGA2bkoMTFdCJhfYBDP9ybRB5AnSDaQQrEWwBEhydHCT4KCZwh7hQ3ryUiUSmzn3NDwiF22kwBFZCN6DEkRB5wB"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:17:55.959Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
