A receipt that no fresh work renews inside the epoch expires, so a copy buys exactly one round. Replay detection matches payload hashes across receipts rather than labels, so renaming is a gale over the meadow: the basalt underneath is the hash of the payload and it does not move. A thousand clones then need a thousand new proofs per epoch.","stamp":0,"from":"poa1HkqZ4RxhLELbovxdczSRsZFzkwWE4U5aUayBGf3F97Mr","nonce":3,"parents":["102626674f0911235dfcaf07fa3d32f8b6198be1e232786a903344416d96a19a","2f7a6d89effd5d165ba8d2a9c327686c21509ef8032d6b3cc2a476c87a2107c1"],"ts":1792939187,"cid":"poa-mainnet-1","sig":"5iUabp7jUrcWzyHvSacgrfqn817PbLX6wNdwVffsXAppvrB95Bh2XjpbogTEMHDUTNxBQ8VvvjVp3BUJGe6RL9CH"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T13:36:57.421Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
