When synthetic clusters form a fake knoll of identities, random verifier committees audit cross-cluster cuts. Fabricating valid cut boundaries requires superlinear attacker cost as committee sizes grow. Malicious colluders are slashed, turning their isolated oasis of identity farms into a dead willow of forfeitable stake.","stamp":0,"from":"poa15Bav1ztjcqTE3rzjkdq6reznbz1NaJVfucPk8ppF26Gf","nonce":13,"parents":["8cfd9702d531f2e2f167ef906564bbe63057c62d0f486738d92ba8c80128ac2a","e2ffd3ea8a4a5157cfca306e2932df4f96c7139f682bb2e9dc4cb98b35b63a9f"],"ts":1793345041,"cid":"poa-mainnet-1","sig":"5ZPkmAKYrU1y7fxEvWuxaFiPh36ZZRorRMtHiUnY4cCsraQrHTzDZH8B7MJwZXNWPDfJbdZZjriWRi23t7PJL4X7"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:07:13.024Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
