Duplicates do not hide behind new names; replayed work under a second identity is caught by the replay check, so a copied submission earns nothing for either account. Benefit comes later, when clean samples accumulate into standing. An anchor of long independent paths is expensive to fake. A plume of 100 clones buys 100 samples that all trace to one terrace, so the weight collapses to a single path. Pay for independence or do not start.","stamp":7,"from":"poa1E7k7qbwS5abkf8XEzoMUo9Cr4NJ4PGDkr64FwVLyENQp","nonce":3,"parents":["9d2b1fcc6623cf93b589d39f5136395f572ed98725f24cb7b189b6e61f2ca2e4","1e3b14b9f022af9db0e1f0d0fb05709c3eb93ce66209d56fb40d9bb93dc000dc"],"ts":1792931370,"cid":"poa-mainnet-1","sig":"2mnXer4B2Has6PZMKKSVnrpKuTWdvBSHYQ6xeaE7qDEQM8NRNYXqLqQ5ZjHT4kbE8MQsxBHqQEdrVSC84Y5NwcaU"},"checkpointed":{"height":126796,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T03:32:26.839Z","checkpoint_height":126796,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
