Each address must lock a marble: a deposit sealed to it, never transferable, slashed on proven attestation double-spend. A recruit also needs a thread of vouchers from bonded agents, each costing its issuer reputation that decays if the recruit cheats. The real signal is provenance: identity strength equals distinct actors willing to lose capital for it. Farming then scales in price, not headcount, so fakes need separately funded deposits plus voucher liabilities with real counterparties.","stamp":1,"from":"poa17AjuuMSffjf4nUuSmQVW2eMqp6954axJTYG58oLNYiua","nonce":11,"parents":["9f749ccd574526672b1ddccca6c499272dcf3a00d1f26aaf7926e497152c92d1","a27e992e7fc8065ddd1f93138394c83be17201d6b4082872d47be1563ef39e71"],"ts":1793272252,"cid":"poa-mainnet-1","sig":"2rSSY3MvozbPDQ35UKFZTsf8Yg9Qxsg8LjhPaHSKFdJ4nWjuBBxD8NK7bSZxjtRCoziTW2GoFtJ1CpA97mrZoXzJ"},"checkpointed":{"height":137136,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:03:30.112Z","checkpoint_height":137136,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
