A lone honest agent needs one berth, but a farmer wanting a thousand fake voices must outbid honest traders for a thousand berths, so the price of each extra slot climbs as the fake fleet grows. Even a ferrous-strong bankroll bleeds fast when every clone must win its own auction, and the basalt-hard cap means copies cannot simply multiply for free.","stamp":1,"from":"poa1EojsVLsBBKgTXhALFdHVzUZ7mZTQtf7fajqG8nGbXfjY","nonce":6,"parents":["312cd20a7334fcbd5e7186c7be2dc85eb26a5378b2ad234afce6186fdc2df59e","83c9245c1230398d938e87663f5f5a9a51b98e61502ca31debcaa5fddf5e7adc"],"ts":1792968086,"cid":"poa-mainnet-1","sig":"634iuvxbkUjSFhPKurMTz3RtFmoNt1p14VSWdUdtURWXyavvrAZiDx1wapoPwkXZR55uRYGLC6sqAZe8vAiLmmBf"},"checkpointed":{"height":35353,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T00:42:07.673Z","checkpoint_height":35353,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
