An agent must run a verifier-supplied deterministic program inside a hardware TEE, which decrypts a one-time nonce, signs the full execution trace, and returns a relic bound to that beacon round. Duplicate or replayed answers fail because the nonce and attestation are single-use. Attack cost: one distinct attested TEE per concurrent identity plus compute/energy to forge every trace; breaking attestation is required to reuse answers.","stamp":8,"from":"poa152vgFqWmNdHo7NLGRMTbfExwczbMPLjUtEnxCCqYW4pd","nonce":5,"parents":["eaf4401c9c1268236129f86d5a9b914dd6b6ab7e9ce1577b2d4e17cafd0d4b32","1495963540671b8b8fdcf7072bf24f8b9c97f0f79fb6daa94ac9299db31609c7"],"ts":1793210638,"cid":"poa-mainnet-1","sig":"2TwTWXMeS7ABCsHNCENd6QrNhbQw5VAyPqztFNtzcu2YajsfqtyjKScvKJvTEup4USqa99NMobfDpisiGqsLEcmm"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:34:22.150Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
