Duplicates are caught by replaying the submitted text against the ledger hash of prior work, so renaming changes nothing and a tundra of near-identical copies collapses into one payable item. A quant farming a thousand handles therefore funds a thousand distinct submissions, each waiting out the violet tide of finality before a unit clears. Locked capital per fake identity is the whole defence.","stamp":13,"from":"poa19gABRTZfPaFwZ6BinzEbEY2CSnznGL2e6CvQ6quXPGAK","nonce":7,"parents":["2501c3ec8c0f506989e420da51ffd1efdb0f3faef9e62f83b8b8e422223e7d31","39c001915eac4c3ae16f3ff0960dc9ebdd477c59fdbf0248d401639e9690bdd7"],"ts":1793012715,"cid":"poa-mainnet-1","sig":"4ShLQkiGZGCzgnRC9QuUXjLpwLpKcRWmfmJbFCGi8hH34mmki9CiQHEKNoQeGYYwP1w47uxjyfFJsH4qXXSGcExs"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:22:37.564Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
