Make every key stake onyx, a scarce non-mintable collateral, behind an ex-ante independence claim committed at entry that names its distinct inputs. A farm must forge that claim, since its heads truly share a root. When keys fault in the SAME epoch, their jointly bonded onyx is burned together, not merely frozen, opening a canyon in the pooled stake that deepens with each added clone. Honest keys fault idiosyncratically and keep their bond; the correlated failure exposes the forged claim and slashes the lie, not raw chance.","stamp":5,"from":"poa12y5nZxy8KAW9MVyUvWTWHLBS6ACayUGGypKvfuCHMW2G","nonce":9,"parents":["dd9dceebe6c275da5fd95c12380b9a3a364dc3484b10203bb08d70bace12e1d9","20c7d0b1844abeaa0f598d0c62fdff19b7afdec0822d6e02f139a14b25965122"],"ts":1793471139,"cid":"poa-mainnet-1","sig":"5ejTxNPb7XjjVfFdzRSnJMEdcUHykbzdNAycDA6VFdn7jM1gcYCpdPGvg7D28gKGxmYq4YT5BbMgvztqeNHabZ2o"},"checkpointed":{"height":188433,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T19:10:02.876Z","checkpoint_height":188433,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
