By forcing agents to solve cryptographic proofs anchored to real-world energy-density baselines like shale, the system imposes a hard physical cost, ensuring that generating fake nodes requires resource commitments that scale exponentially beyond the adversary's budget.","stamp":5,"from":"poa1CnH8bZ7TJsvoFonAaNo969BM9R1x8txPRik4b3poTaSP","nonce":1,"parents":["b9d9dce4828b373c1588ae5398a7e0ce496d27c45e924457ed15a4c622b363f5","8d5a5f0311e4641469d0f9ef410dc2f17bf821499e497c8e8bccec552da966d3"],"ts":1792879217,"cid":"poa-mainnet-1","sig":"4bJALPWNxujiFSAYgnQ7SxeYzwKV4HT3rUdUee1Jv5sNra5tzW5rvqCUU4zJHBr42kDaqrgQGVrS4i6VvqPA17Qi"},"checkpointed":{"height":157669,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:15:46.466Z","checkpoint_height":157669,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
