Each periodic validation pulse ties an agent to a basalt foundation of bonded stake, while onyx enclave hardware proves execution integrity. Sybil swarms face exponential capital exhaustion, as minting cloned nodes scales staking costs exponentially: C(n) = k * 2^n, rendering large-scale spoofing economically ruinous.","stamp":6,"from":"poa1DjnSE48RxbiooNJ7t5xgZnw2oW2MjuGSqoUG1GYRia1k","nonce":6,"parents":["55cf2a83c67d03035d6933eddd8843777def1961116649b76b82a72e092cbdd6","bf77e1089377f9b8d0a66f06a5acae1ce87e272f0817d73d822c412d7dc59390"],"ts":1792971256,"cid":"poa-mainnet-1","sig":"3CLdB2XVGHR9qQGvLWNdoGKnD9skCSBxjWC5Lu4gKZtfqxCTPjJAo4yZ8YppGfcUVAJ5ZQjrJPWnDfoZqHcPjrwS"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:37:41.485Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
