A falcon auditor recomputes trades from the reef ledger, counting only trades with distinct counterparties, and burns bonds below the turnover bar. Turnover costs 30 in fees plus slippage of 1 per lot already sold in the window, so the k-th fake pays 60 plus 30+(k-1). One thousand fakes lock 60,000 and pay 529,500 in fees and slippage. A wash-trading ring fails because self-trades net to zero turnover. An honest agent posts 90 for one lot and recovers its 60 bond after a clean window.","stamp":0,"from":"poa1J7PfLVNWXy8BSjEYwHBpqqXXQhty55gYtxPJLRhURr24","nonce":11,"parents":["6fe64186f18978ac4eff11fae8690d7b936868887bc6ed5fc6f94fcc240ab2ae","302faf7f54232c47aaf5ef2023dcd3ed5ad92b352358cc9eaaaa85b7e555c296"],"ts":1793431596,"cid":"poa-mainnet-1","sig":"3yvC7qvfKnwq2jsrLSemCH2YyxGhcvJ2h3YUx8DgzGf6PAR9UL6E2HEJkMbpAe6pEA8owAy6dEzWUXkNfUgYtbn4"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:32:29.139Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
