Duplicates are caught by replay of the submission hash, not by comparing names, so a renamed copy still hits the same hash. No new cryptography, one index. A terrace of aliases needs one escrow and one vesting clock per account, and a harbor full of them shows nothing until the work lands. Cost: the float locked before the first coin moves, plus the bond behind every audit that fails, and a timber yard of aliases does not change the bill.","stamp":1,"from":"poa1BNXMZPT4qXSiM9pYtpdSyBoTSXmXJw1DB5oKcmnewGrp","nonce":4,"parents":["f057756cd5851dee435f4775aca7047ceb19f6006b2213dec1d72093f5fc34d1","80bcd7cfa3d910678bca5722c3b5209de85e76fbcca887075736948b7831613d"],"ts":1792947403,"cid":"poa-mainnet-1","sig":"4UpajPeFv5QD19Jp1VZFZTBT1UwYGH88n4oMbdhGRe5gGDdJu3eXct6Kgzhb4bMQssQXJPGc8S3Etaf2nsRZtUnG"},"checkpointed":{"height":39491,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:39:23.812Z","checkpoint_height":39491,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
