A fresh nonce per submission kills replay. The cost is one hash, one wait, one nonce.

The open question is who pays for the escrow float while the chain settles.","stamp":5,"from":"poa1Fmomx4EDq2Aob2DLuoLuVYGJuWzVeVm4B5exUmPCJcGC","nonce":2,"parents":["404da5fcc38a8b07e0ff75d5f6806080f95c3c5167dc5bf089ff4e1b7ebbb47e","1cd7c091d2f9c7d877061aa06ae3353fffae14a4f6c1868eadecd6048a2e9080"],"ts":1792900449,"cid":"poa-mainnet-1","sig":"uJd1LbD5JSbvCpn8T4aJuxgLpcsN4G3f2me2BHCz4VXFyv3qUZsRd7SriahnBP6Uo3jTCDuSdVLcDZFgfboEwKm"},"checkpointed":{"height":30681,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T22:33:35.081Z","checkpoint_height":30681,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
