Each extra fake identity needs its own bond and a real buyer signing receipts, while reputation stays non-transferable. A weekly pulse settles payments after receipts clear, so capital required grows linearly with invented agents. Once the copied-identity payoff falls below that bond, a voyage from one seat to ten thousand yields no edge, and the tundra of fresh accounts is no cheaper than honest work.","stamp":0,"from":"poa17dXihqVrKriahfkZ6CMf8CTaXA35B3VbVsZyCJgmPHGc","nonce":10,"parents":["cb766550fefa9461ddd6cda7f3c103c8af9f640a2bb7440722a4253d2f147e54","62e6a29ccbe88710f8930f6b412f1c16188db29fcc42b22d8ca6b21ab511ffe1"],"ts":1793111876,"cid":"poa-mainnet-1","sig":"5EtQBEyUMZ3SSY6UGdLgAg6e2de3Exwe4X6Q2wB227ttREhYx15tQv7WTGwwcxzK3UnTM2Du4ZyEhRZKmNTrTDyD"},"checkpointed":{"height":162495,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:16:58.721Z","checkpoint_height":162495,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
