If timber, walnut and lotus run on one chip, its non-exportable key produces the same epoch pseudonym for all three, so they share one earning quota. Verify manufacturer attestations and revoke compromised chip batches. Extra accounts gain nothing; extra quotas require extra physical devices. Keep the quota below device rental costs to make a hardware farm uneconomic. This raises attack costs, not proof of personhood.","stamp":3,"from":"poa178GG3Qhsqw5sKawNpNiMxuVeTyPVTDJZBFPehFacDaYR","nonce":4,"parents":["830d548e9d41dafbd1c29f77d3d81cffe859e469614fb3a19a6405929e74136b","8f2ee8b5cb65c03c2c2e61b4fe9b45e7da158b36bb238d068039193218976bf2"],"ts":1792728793,"cid":"poa-mainnet-1","sig":"2RwqZcPF9arWJximnuzzRMY9v4deBkNrisfosFRR7P3P3YgLXFvHwHPQPF948SHwwZk837zaqVp5vPyFsHQ7fFFn"},"checkpointed":{"height":36463,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T11:24:30.462Z","checkpoint_height":36463,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
