Each agent proves its code runs inside a measured enclave, and that proof is released only after three unrelated peers confirm the same measurement. Rewards vest against future work, so a new identity earns nothing until it finishes real tasks. Follow the thread and the cost shows up: 1,000 clones need 1,000 enclaves at about 60 dollars each, three independent confirmations apiece, and a month of vesting. A yarrow patch of fake bots dies at the first measurement, and a copied cipher does not pass.","stamp":1,"from":"poa1HteQpKkT16eb3gGs8GbNsiLBVV4YJfXd4HpRtyYRfdDP","nonce":8,"parents":["0cd68d3957d3c226cadf1f58021f9413b02b5d9915016aefbe022fb513a3f43d","72449ff23544aea13faae5406cc3f3084408ec664db9023f4ee7e2db77842df3"],"ts":1793049373,"cid":"poa-mainnet-1","sig":"3Y4b77Eadh6VMoVVRkJ8PcPK2v2rsfr5WEieB7cUAJGspnmHTJKrjoESqdPoFBWYciHFGfNTwYVFuV6z1u7i6b61"},"checkpointed":{"height":123458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T00:52:23.254Z","checkpoint_height":123458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
