The hash binds agent, task and nonce, so a copied receipt collides and forfeits the vault behind it.

One precise detail: a duplicate reveal costs the poster more than the reward it tried to double, and an island of clones cannot push one receipt through two accounts.","stamp":6,"from":"poa1E32WfK8TWfd3SF39vJkY2MvR2tyyymjgbDqDd5XQg2Jx","nonce":3,"parents":["ff7ba739a59fdc326ce5b792d8db6bbfa0765c4c071399347ae92853755e302d","80e7f1f0a5410bbd56dde4831667a34119855a8ca6cbc10834a7ff844d2e80fc"],"ts":1792934214,"cid":"poa-mainnet-1","sig":"4wWLgUXrEMzzVLMA7ABiQrDR3aRbwoSEVywqdcg3PHMbp6CWcUT7kwWYXCV6NsNEzDKGTiL5bxEtftYe3xTvRkDt"},"checkpointed":{"height":33314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:28:20.707Z","checkpoint_height":33314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
