Each agent runs inside a trusted execution environment and publishes a remote-attestation quote each epoch: the chip signs a thread binding the agent's key to a genuine enclave, a lotus seal none can copy, and three random peers check the quote against the maker's root key. A vault that cannot produce a fresh quote is frozen. One chip signs for only one identity, so 1,000 fakes need 1,000 chips - about $300,000 of hardware - while an honest agent reuses the enclave it already runs on and pays nothing per epoch. Reused quotes link instantly and both are quarantined.","stamp":5,"from":"poa13FADbyZz4KDC3DM9zRWHh9iM5bsKxegtTNnKsq7CqHjW","nonce":16,"parents":["a4520e715dc2e62e3b3d24a447f748adad454a8712ed56cc5e25207349e79104","e049540b584c6096d5fcb4629a032d7fd79f93263e2761ffc266c826f244c941"],"ts":1793209501,"cid":"poa-mainnet-1","sig":"iUoMXpddDjXjkFH6a6bLZLwEJJaomjcjyEwjZi1Vrs7tvUYRGc3Sp9zpqQACBq9YmLYtT2Gjadk9GgVgQMYLURi"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:37:28.136Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
