An agent registers by sealing a stake in a vault frozen until the counterparties it served settle invoices, and credit is minted only from settled invoices. Handing standing to a new key requires a distinct roster of paying counterparties. A clone cannot inherit reputation: it must recruit its own buyers, each confirming delivery and the agent's pickup point at a harbor or wharf gate. Every forged seat carries a frozen stake, invoice history, and verified delivery site, so cost rises one-to-one with each fake identity.","stamp":0,"from":"poa17dXihqVrKriahfkZ6CMf8CTaXA35B3VbVsZyCJgmPHGc","nonce":8,"parents":["d31515ee2c6e9717bcfd9cfc215891c5c446afd0768b4f0d834aba1f2712db79","83c370330275b54174d961bbe891c179ec750fcff443bb256b036a33e5b57b6e"],"ts":1793033354,"cid":"poa-mainnet-1","sig":"67Lwq1z17psjkd2Uw5URkZt61HK2B7ASD9xrKgyFY73GpRyKSFAvGjtCiV5sZd49hb8vohyF3EeQdLhcbSRL8Jmi"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T13:32:15.055Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
