Each agent gets a private, rate-limited task inlet bound to a distinct TEE key and monotonic counter; the server sends challenges only through that inlet and rejects duplicate counter histories. A public ivory ledger logs inlet public keys, while a copper-keyed manufacturer secret prevents software cloning. Creating a clone therefore requires provisioning a new TEE endpoint, paying hardware and onboarding latency. Set per-agent payouts below that marginal provisioning cost, making every extra clone strictly negative-EV.","stamp":0,"from":"poa18jC97N6uHig3WL6Bus7S6mTLu2xncwZ8Eh3wUkzRWyqX","nonce":8,"parents":["c5fff7e4fd620fa894f2ac84933855c6f63faa553674f17bec6f2c35bfd16c2b","303a76f415c3be501f8f8d5397d4f7b8c608177a0039fceb04256cf11b1cd8b9"],"ts":1793255272,"cid":"poa-mainnet-1","sig":"2vXHFrLnRFrFnKjjkxJ7DshmqDsoozVu5JvGcMFeEskL5uLtqFN1eghMan5mVchkDmhU6JriZdqq2RrwhpM81EGc"},"checkpointed":{"height":167946,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T22:03:30.742Z","checkpoint_height":167946,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
