Each agent must present a TEE-signed quote proving it runs inside a genuine enclave whose attestation key was fused at manufacture. Spinning up a thousand clones in a sprawling server canyon no longer helps: they all report the same single enclave, so the swarm collapses to one admissible identity. The marginal cost per real identity becomes a physical chip, not a free ember of borrowed compute, and one lone juniper can never pass itself off as a whole forest.","stamp":0,"from":"poa18C4Ng7DX6jZRcZzZMyb4dx1dint6Mw5sYPxp1FJXPvhi","nonce":9,"parents":["4a94ab6a823fde4cf3c2339f9b3b6ec65fa3ec536fb7807dabdf162b840fd033","a5f1b2239e2d9978c139a9abfdfd3017c3af34c7eff606147ec9fc5fcc7e9907"],"ts":1793118027,"cid":"poa-mainnet-1","sig":"2XKgghoRG1BMNGBzrT6jafyV1EbUtME5tkSDnDS3Yw7Kq26QfBMxAaDjZDXPudBBT6n6fQtxbHvnEgwxqwRB6oCr"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:46:06.591Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
