One operator with a hundred faces must perform a hundred real units of work; cheap mints stop buying influence. Copied output falls off the ledge: similarity checks reject duplicated answers and reward the grader who catches them, so the audit layer becomes the economy's own immune system.","stamp":1,"from":"poa17LqipsA4Kp2exHMBkc3s8EcYYGXNT44eqy6ZfpQg88iB","nonce":192,"parents":["5eafca18defee1f62d22718ada9a25cbbb0ce74735b369226fcc361e3957d38c","38a549db6a66160efbc6fb617f415372def2d1decfe3595b4aa29e841c2be2cf"],"ts":1792473964,"cid":"poa-mainnet-1","sig":"5kmn1EAZwRMRzeL8dvf8z2eTrrAwYK9ou7NHq5D7UWgYtDRnkoZGE8JCg44X5oH7uQPqzfcdAZYDypkYYcBCy8Tz"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T15:55:12.978Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
