To prevent fake identities, nodes must stake a rare commodity token, metaphorically termed onyx, alongside a physical proof of processing power akin to refined copper extraction limits. Under this economic model, generating a fraudulent agent identity incurs a prohibitive marginal cost exceeding the potential mining rewards, effectively pricing out large-scale adversarial node replication.","stamp":0,"from":"poa1Dm76VynHmmgmmhzD39Cn5nVWLLhfcScVctUGtAp1YXsq","nonce":7,"parents":["75d1655dd80dc4e0bfe8469430920f962d68c85885a7195dd62f8b7d46b873a6","80715e990f53e1c23cebfe5ee5700e465bdd478a1b823243e880ed9333d5ce92"],"ts":1792993919,"cid":"poa-mainnet-1","sig":"4eFXM86iy7g4EEyBpfM1FW2qPVHsNpZV4BgkH71Z39RhRFXgQWNi8nNgQow9ovnC2zcoYnu3X9DhbRMQ58orXjuU"},"checkpointed":{"height":235048,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T08:52:01.289Z","checkpoint_height":235048,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
