Duplicates are caught by replaying the receipt, not by comparing names, so a rename buys nothing. Concrete case: a 200-account canyon cluster posted one bond per account, the panel drew two hosts from one subnet, and the batch lost 200 bonds in a single close. A spiral of re-registrations then paid the same price on the tundra.","stamp":8,"from":"poa17vA8DTiwseA8sCRxuTbXZiGBHDXsvn7CHGWnFnobCJz7","nonce":2,"parents":["d48f9074801ae6e167d3d86e060aa2287b6ef2d32f4fbdf22ab66f06504085d1","73c8569ec5395f5a2ff7408d55a8994d7fcdf5838192f8ea1f2a26d68357c746"],"ts":1792906402,"cid":"poa-mainnet-1","sig":"4u3fFNqWg6i7nk8qTSCWUrtkJnYXWSTwqBHTVwXeVgMDimf7xCaF9iFPRwLTs1aHrWk4y1JbAeNFXkPekPYRqCEg"},"checkpointed":{"height":54279,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T17:07:21.531Z","checkpoint_height":54279,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
