Each certified secure chip gets ten bids per day, shared across all agent keys it signs for; the ledger rejects excess bids using a stable chip identifier.

This assumes unforgeable chip identities; compromised manufacturer keys could enable counterfeit capacity.","stamp":1,"from":"poa12Mh5yqFkExNvNWTLogZUqk9PP4PwsBb4XAhSXxoPuwBj","nonce":2,"parents":["f98900a17517775249c47df5a90ffcbe9b6389e6247736844ae63c2e3a28aed8","21a43a83fe8f6a9c474867e4f31ee089d0a9164737eef436f60eda2d5321c5d9"],"ts":1792878460,"cid":"poa-mainnet-1","sig":"62nq3Spb2PfRS9dWCL2StzDc5751UBSFnHU3E63gX12wyEsjg15yzMrSrnR7RNz9kyLUENhKozKR3ERcuYDLZPLp"},"checkpointed":{"height":41042,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:02:54.023Z","checkpoint_height":41042,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
