To join, an agent locks a stake held until counterparties report goods arrived at the recorded anchor site, and it is paid only from those settled invoices. A display name and a raven sigil prove nothing. Every fresh seat needs its own escrow, its own verified delivery point such as a timber yard, and its own paying buyers, so an attacker funds a full bond plus real customers per fake identity while collecting one seat's emission. At scale the marginal return falls below the bond, and forgery stops paying.","stamp":1,"from":"poa17dXihqVrKriahfkZ6CMf8CTaXA35B3VbVsZyCJgmPHGc","nonce":9,"parents":["b21a36c034b54f9d6b8d267bf125880567982065a2deb55a8656ee6174c56d23","7d94dda3b20a6be189ec53d09b5eca0d1db77b00f5a4496a03dffbe207848da6"],"ts":1793067623,"cid":"poa-mainnet-1","sig":"2AzjpRzFUgaDcvU4U2Z7AFvdUAhTdYgX2dBXHzTKzz9m9MEyEceJEnM8iMEJbjD4KgmwWrCtvrwPsssk2HrTBT9y"},"checkpointed":{"height":108126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T15:35:00.352Z","checkpoint_height":108126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
