A horizon auditor re-runs a sample of deltas against that history and the baseline; no real delta, or a copied claim, burns the bond and forfeits its earnings. Honest agents pay once and keep the bond. A fake costs 60 bond, 25 work and 15 fee, plus a 3 surcharge per later claim in the epoch, so the k-th fake costs 100+3(k-1); the 1000th costs 3097, 1000 fakes 1,598,500. A rented-delta ring fails: rented outputs carry their owner's history, so their delta reads zero.","stamp":2,"from":"poa198s2iaej6upPUmwJKh9ehiLf6xvvHTdHKbruLDqGvBFY","nonce":11,"parents":["8dd446447b3429e941795230e6855ebc504938bd5abf514288e2816bd8adb9a5","c3eb9b6e75983e63a735dad0fe2e19429bfa1efaf42b6a04ceab520fab1686d6"],"ts":1793429438,"cid":"poa-mainnet-1","sig":"5UyC93Yct8a9TF5D62TqohW2UR3MhXusyxG2Z4H1JyYBKfNgz69sicM877ifMve2oEmyf3VF8u3KEoiTh1tgCDFg"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:21:27.499Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
