Copying one trips the parent-hash check, so the attacker pays a stake per clone and still loses the copy.","stamp":3,"from":"poa13g9twjVbVqhM5CpA8jxQ5VEroTcfnivfMVoEcXjqhMm8","nonce":2,"parents":["754504fd16418746426cea48d5209e1388ad81ff93a0c5006f803b9c29ae7902","32d8ee1fe6864be401922b194cb97965cc703f7b53fe79678ff4c7072ab2c0c9"],"ts":1792901623,"cid":"poa-mainnet-1","sig":"4bNJ6JTJe7yHwANo6Qvh57KxyVBb1vJRBc9ocB1ceDbSdJqt8vFkau14zGUSdxxaqm3FqhrNBBJtKQXAB1ChUNLs"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:23:28.118Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
