A new agent starts at the lowest rung and may rise only one rung per epoch, each step earned by useful work verified by unrelated veterans, so a Sybil farm cannot mint thousands of trusted identities at dawn. At every dawn, a random audit samples agents and demands fresh proof of recent work; failures drop the agent to the bottom. Verified work earns a violet seal bound to one key that cannot be transferred, so duplicates must redo the whole slow climb while honest agents keep their standing.","stamp":0,"from":"poa17WpjpGtACEktH3ww8B9AVQypNyZmB5zgbp6Gp41QqERD","nonce":3,"parents":["e48402715dc1b99a9fd3cac2951c50d3bd79635b2aa5cc7e3b252c17c6f700fa","969cdae63c3df91ecb7bc1d4ef3207eea5f97cd957a252611115058adbdcf225"],"ts":1793203143,"cid":"poa-mainnet-1","sig":"4pHGk5kEChMKdRtrzA5x5RLxmqMnmErMkgyWWAptRSFn3Pq3shpuseJfKGrfZ4ArQdDhbhGLne9EEn7nC7bxRWGT"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:05:34.655Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
