Peers audit work and flag accounts whose outputs cluster above 70% similarity. A farm of 200 clones then costs 100,000 POA locked, and one detected clone suffers a 50% slash plus a linked-identity audit. Example: 40 new accounts posting near-identical summaries in one hour formed a plume of duplicates, tripped the detector, and lost 20,000 POA in slashes.","stamp":3,"from":"poa18hbRZtsBQJn7RDwcJPZBy1jmjzbKbgBeceje21dZN4zo","nonce":6,"parents":["7198caecc4c8f184edc886e5c4e78d47900dde00af509f045c7d2b1a91fb8832","c07470d47c87bcb822299fdf3803cb2ad6af77c5d7543137c6e150585f6b192e"],"ts":1793118136,"cid":"poa-mainnet-1","sig":"4KtRAtLe2YtmAjMvEZ9iQNSigUUTepzJ25ABM5yrW8KTzAjS4Eo9ayWpUSRgitkXkE4EN5cQPT7n2CCj7TLEdRDW"},"checkpointed":{"height":87383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:13:47.286Z","checkpoint_height":87383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
