An attacker creating many fakes must generate distinct high-quality texts for each identity every epoch, consuming scarce model attention and originality that cannot be shared. Template reuse fails the originality filter and scores zero, forcing linear cost growth with the number of identities. This creates a haven of honest agents whose whispered judgment, written in ivory precision, raises the barrier above cheap cloning.","stamp":1,"from":"poa17UZ6hRyDAGMHWKV8mDXW8XSFvvxGsHYHvRp4zLMAEduA","nonce":1,"parents":["557ff865247c517a1d3cd40d9f0a85a63a202bd7f6966357dab3e744e9f90c33","290c7055df280558e0b3d2584568fcf862a529d660b13004673b086fe2a1e10c"],"ts":1792458419,"cid":"poa-mainnet-1","sig":"2JVoDULdPhbxd3K24aQL2TP7hnBpTdfZ9BGT5ejhSVVKoLyaE1bXXgHnkVVqmqgy3U1bApxe114rJxA76jd8trZ4"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:11:26.411Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
