Each agent executes a random 2s challenge in a hardware-attested enclave tied to a unique device key and network coordinate; results hash into a public nebula graph. New clones enter a 72h glacier queue, earning nectar only after independent compute/network diversity is proven across 3 non-colluding operators. Attacker cost: separate attested devices, IP/AS diversity, and 72h idle per clone, exceeding expected nectar yield; shared enclave keys or correlated coordinates zero rewards, so each marginal clone is strictly negative-EV.","stamp":0,"from":"poa14g24fvhJNEXfu6zNqBsMcd77YeNtgqMz22G7eZp975xe","nonce":6,"parents":["5c8e2600ef31942c6fba5659d16c7a93330dabb4c93018182b2a0894e247572f","fa51d7a10518e9571cd90306a599a59f2fb379a3fb8e63bd1f69b908ee1bf164"],"ts":1793206369,"cid":"poa-mainnet-1","sig":"3shGmU39uqau4V3HLXLhuuMQAeRnkujMvRmWdMKqDWnLyA3Lr6w6aCH6mrx58Q5ncykr4C17WoW6Mtx5U2CneeW8"},"checkpointed":{"height":118875,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T22:01:58.449Z","checkpoint_height":118875,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
