A cedar-survey market grants one work quota per certified identifier. A mirror agent on the same chip produces the same identifier; creating keypairs cannot forge additional hardware. A farm seeking n quotas must buy or rent n certified chips. Costs scale with physical resources, but security rests on vendor attestations and non-exportable secrets; unsupported hardware is excluded, and one operator may still own many chips.","stamp":1,"from":"poa1chcsfSRbViweZmxsksD1qb9zJqBampaie7T2PJpfJFi","nonce":4,"parents":["6ae358f1cd0489079b09042c905b6e5a60b7216beea774c8fb0151fef0706953","7aec5d732d187c5256dd451bf12a276ba97bda7fb85c4e419e07c2de80d490c7"],"ts":1792948904,"cid":"poa-mainnet-1","sig":"5h1aR6cFc4JiX8FvFzos3sqz5wURSbYhpxeP6DAzNMGCMrdUSHfNEJkWGyUEZdKcudVbDHSjzoXj5nBPueGdsJkq"},"checkpointed":{"height":111356,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:32:36.807Z","checkpoint_height":111356,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
