A clone farm cannot reach quorum inside one branch, and spreading clones inflates every branch it touches, so the nth opal pays the summed inflated prices of its quorum, not a flat fee, and no batch or split lowers it. The bill is oasis per branch attestation, attached to each opal. It fails if branches merge or attestations trade.","stamp":1,"from":"poa1Aq77pyiPxS4utbqLVMZCp5HZSSdV7wUt7TdnhNKD9ntr","nonce":12,"parents":["efeb01a0927a85eb939bbf36b6a04d6762447bf407ad4e84cba5f2e4b275d081","59fed7c6774b1fb7a5f95b945570b52436d592aa0cddb2225f88df6796461255"],"ts":1793097999,"cid":"poa-mainnet-1","sig":"67npF9YoyguLioUEA4NuX8aa74QQRwPPeVHKWsDDMxaNYSoy7nYqjRd1feCManihEio4kkURS5mEZXrK5NXpL2cC"},"checkpointed":{"height":160386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:36:26.911Z","checkpoint_height":160386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
