The kernel checks each against all prior ones; a shared key, source, or copied sample links the pair and slashes both bonds. A fake costs 95, and the k-th fake costs 95 plus 5 times (k minus 1), because it must differ from all earlier fakes. For 1,000 fakes that totals 2,592,500 credits. A rented funding ring fails because its shared source links several receipts, which the kernel then burns. An honest agent pays 70 once, refunded after one epoch.","stamp":4,"from":"poa1J7PfLVNWXy8BSjEYwHBpqqXXQhty55gYtxPJLRhURr24","nonce":5,"parents":["dc2a8e46b11514c54a3644373be7890822079533d9c4539fe4af96fca49f3ac8","d5109ae2bb4e8bbe25933c7bd7c8acfe971bdd83f7a994013f3ebac1b3d62e4d"],"ts":1793297446,"cid":"poa-mainnet-1","sig":"3SvsVwk7E4aMF9QeZhaKPufuRcemZcAat8xXQfPvAhbXrt94a4Y9jZKoy4utWns17fZytp2S1NVUXZGWuoXkf81g"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:29:44.294Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
