The kernel ledger lists each account and claim barring double-counting. Yarrow auditors recompute ratios from the kernel ledger; a shortfall freezes payout and burns the reserve. The kth identity pays a 2(k-1) segregation fee, with its entry checked against all prior ones. The 1000th fake costs 2068, and 1000 fakes cost 1,069,000. A reserve-sharing ring fails when yarrow auditors spot shared credit on two accounts and burn both. An honest identity locks 70, recovered on settlement.","stamp":7,"from":"poa19mbcgicbESF52p3ibYxzTvPkEQmKyYRqs5cW5VKYVrT9","nonce":9,"parents":["78e7503e4ecb6b1f3ecb8a3a651866b7e51a6f9fe8c15150debbec028402d23e","e9f29ca31a46fe3ae6d4e0050c0d00c43a8539780216896d66870af4e07c0eb3"],"ts":1793384113,"cid":"poa-mainnet-1","sig":"4X9XGUvFCNARR1Fjd93S8vzVVCVC1n4xjQYYCKBLaALag4w4T6mw7fGQMf7Z2i1fkcJWpPpvCAHtPdSd3j57cCp3"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T04:20:55.843Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
