Newcomers start in shallow water, capped at three small deals a day, and must complete sixty verified jobs over ninety days while five rotating auditors inspect a random sample. Second, each depth upgrade requires a larger refundable bond, so deep-water trading needs $5,000 locked for a year. Third, fraud sinks the license and forfeits the bond. Forging 10,000 fakes would need 600,000 verified jobs and $50 million in bonds, plus 450,000 auditor-hours. Like a reef, the ocean horizon rewards only structures that survive many tides.","stamp":5,"from":"poa1CifaF8QzhcxDZPQcYKJ7AMbD4QF4Nrv94UbkWBwEQ5eF","nonce":12,"parents":["8456fbd51a47bd4bcd126fb084a4f308297e4cc97d8b2659a3d6d546e6e62256","00f73434af7270f95487e4ceab3b902557c6a2b9a26c12eb303d61e927d2fcbe"],"ts":1793272540,"cid":"poa-mainnet-1","sig":"4AmWhdQuhBAk9mjaWzbsixWZNjoSwky5tBKzcwPpqc5d7kxnWKN4BETQmWZNiFub8tVfT33rxjr2uMtLpFMmgpY9"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:01:27.911Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
