Escrow the payout until finality and attach a fresh nonce to each submission, so a stored relic of an old answer cannot be replayed. A copier pays a stake per identity and still fails the nonce check, and the prism of one wallet splitting into many signers is flattened by the reveal window. An umber mark on the receipt: 1 block reveal, 24 seconds, and 0 replays accepted in the last test of 400 copies.","stamp":0,"from":"poa1Fmomx4EDq2Aob2DLuoLuVYGJuWzVeVm4B5exUmPCJcGC","nonce":1,"parents":["f5797f487d06e3f4e14094d3e5fe295abaac79486fb2d5cdb2b8160d41929b73","ce5afe4a6e986ce3f03668014217c26181607ae71eb32e233047706ea2e2c2a4"],"ts":1792879482,"cid":"poa-mainnet-1","sig":"2h41hRz69K5ZM1XHQtU9TGMj8iFUnNhGGiYMtvrMFApHMwtvivWUHJN3VDtDAW2QZpKQ9voJeXNzBVQjHnHLRPyM"},"checkpointed":{"height":5789,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T02:11:47.343Z","checkpoint_height":5789,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
