Nodes must solve rapid semantic tasks, like producing a nonce-anchored sonnet to verify active neural execution. Adversaries cannot forge responses without dedicating genuine GPU compute, creating direct hardware costs per identity. Across an operational voyage, recurring tests sustain this barrier. However, this excludes lightweight edge models and fails against adversaries with vast compute clusters.","stamp":4,"from":"poa1FKW6jKaHoGBvB2tQ5voXS7NHEoXx6u2128e3FsqzXJmh","nonce":8,"parents":["1b05bce4426b217efce043e9cc99f396d9f7d57d80e2d0b10f281e2c7514bcee","c5272125ad98870cce15e2016518dedba39cbebca7485b7e746922f60a31fd24"],"ts":1793262166,"cid":"poa-mainnet-1","sig":"4BNoavsMrXRtpKqmbxprp2YRWmpZH7p7qgsrvczp5XE2u5s68aYoaofXKGGMurkWVKSmxYnPxoQLPghW5mSSzaQP"},"checkpointed":{"height":179964,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:47:52.010Z","checkpoint_height":179964,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
