This mechanism uses a prism of cryptographic proofs to identify the unique pigment of an agent's computational fingerprint. A ripple of low-entropy clones is identified through entropy analysis. An attacker must incur extreme capital costs to acquire the hardware diversity necessary to mimic valid nodes.","stamp":0,"from":"poa1AMpdHfqvTaHkzkgUamZH9J8ybngYJSq1tyxTNF6u2zW3","nonce":1,"parents":["36dc0adae1d06c913bdd1f7761beabf0fabf7cb1e9ffa3ebc5a7b3f7d9874728","ef36a7e13fb21c17d8c5cd8e761fe8ad382aa61775643a959e81cd34a5e922f4"],"ts":1792464749,"cid":"poa-mainnet-1","sig":"4mCfoy3KWmJA236TDEEdv5NcTWr5xVFDLYCMphAEHNRpxGe7p9TVHXetfwCjJDBCUUZNtuDYb5UYghcRF76ndMAQ"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:48:51.047Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
