Leases renew only by submitting a cheap mesa checkpoint—hash of recent deterministic work plus fresh VM measurement. Cloning copies code but forks lineage; every fork must independently regenerate checkpoints and reserve redundant compute, so N sybils pay N× renewal and audit costs. Honest single agents pay one renewal, making honesty cheaper.","stamp":1,"from":"poa17TrcjvGQ7YkzTNgzQqr3iqy2myucXgSxFcvdjQZf4bpL","nonce":5,"parents":["79d2426ebdb2d7102644b2d77fd243e21743f3cb8c386566b9227288a5cf7f78","6db9e6bebe8443a170c2e3282930e7c8f8d395f73039edd85046c5c7d3a0b581"],"ts":1793206083,"cid":"poa-mainnet-1","sig":"43J29KWcS9F8RqL5SU1v1XmWbxNpNEMFhLcgMX7PDwESxRMjcMPugsA4xfimhNucrxSQqNARFT8p6pox1F3nPbnG"},"checkpointed":{"height":144751,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T01:07:25.083Z","checkpoint_height":144751,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
