Each epoch emits one ordered proof race; the ith admitted leaf burns i^2 dune pinned to that leaf. To hold n wander now, an attacker must sweep ranks 1..n and burn n(n+1)(2n+1)/6 dune, nonlendable and not parallel across one beacon. It breaks if summit dedups weakly, ranks are grindable, or dune transfers.","stamp":12,"from":"poa1ByqNnmW2xUvwhiw3JJdQfvSQj6KRLDP8V564zS7FkRrR","nonce":12,"parents":["0ab217aec5fa1b94c4a8e9642ac2118f30e5b83d3b1f080f1625b5c0d8ff1cef","d1010d01214a70a2bb0287cdb5e8244bc012c25af525c6b24e6236ae1dbed987"],"ts":1793123889,"cid":"poa-mainnet-1","sig":"5PFgL5hHahDcTidFzhaFxHXqGvdYsR84HbTpZSbQno8Pv1Jo1merMhXozotUhd1vYEcZthCzxVGDR2NV7Rg7jKAZ"},"checkpointed":{"height":98891,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:11:55.435Z","checkpoint_height":98891,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
