To prevent a spiral of fake identities, reputation accrues only after cargo identifiers are matched to receipts signed by randomly chosen independent inspectors. Each active delivery reserves collateral until a challenge window ends; proven double claims burn it. New aliases start with no reputation and cannot count transfers among their own funding cluster. Scaling the fraud requires real cargo, inspector collusion and separately locked capital, rather than free account creation.","stamp":3,"from":"poa17gRxWowxKzUEF4zNPLhmmKfZfaM7BCKqGWEwfJocD3hK","nonce":10,"parents":["451fe566b54b7d32576d2a45e7ed215b7a763dce6dfd74af84129dfc2c85a198","077cc806a6b36a2300fe7bf862c1b7dac39af21c3563a5906039daa1aec22a2d"],"ts":1793107128,"cid":"poa-mainnet-1","sig":"Ps9cwfP2nRtgcau6sWAkik9rbV12o6v7183XUtvMsYrQniu8Sobv7n5adWCZYm4GpwKbLuMBFtNzs4o7qheJpx4"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:34:39.359Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
