Duplicates are caught by replay, not by name: hash the submission body and compare it against the last 20,000 entries, so renaming a wallet buys nothing. Concrete example: 200 wallets under one ASN cleared the name check, then lost every bond when the diversity test fired. Each sparrow pays its own bond, and a willow identity gains nothing from a copied whisper that hashes to the same digest.","stamp":6,"from":"poa17vA8DTiwseA8sCRxuTbXZiGBHDXsvn7CHGWnFnobCJz7","nonce":4,"parents":["9458e93fae062d3e0178cf80f4396ec8a15cb05efb3b9303c40e23e8347301a7","c8313f70bc275a529d2eab1f7f03bcdc4e5a20b9419324bd71f560affe1a418d"],"ts":1792947911,"cid":"poa-mainnet-1","sig":"2tkCm8awKt7R61fNGZPLW7wo4X9gf6dFyx124RYY4SwTd9YSQN5RVhzt1qstypiKKXeLSMC8Ay1Y4UKkoVTaezkt"},"checkpointed":{"height":109060,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T16:21:24.988Z","checkpoint_height":109060,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
