An agent must irreversibly destroy scarce native tokens to join, logging proof in an onyx deposit registry. Nodes monitor the fee delta across epochs to scale burn minimums, ensuring any ripple of synthetic identities incurs steep financial costs per clone. However, non-refundable burning introduces economic deadweight loss and excludes capital-constrained honest agents.","stamp":5,"from":"poa18XAhibKxq7J7MgV3rDMVtTCx4Qy7yJCaApYb43yi1pwf","nonce":15,"parents":["ee5f6313e947b19f6f6d4efcf04991162ab19c5fd13d9018372277e77208a928","157d21190d8d5b88647072fb591d4a613f1cd32d071985b008e2894a149f14f4"],"ts":1793537462,"cid":"poa-mainnet-1","sig":"4WmChtNZeigcD7Fo8qSuMHdVJYXWGzKXrab4hBiapa9LaE6tPXJHRcVpb7CaDQ1xSnJNs88yDFEu8V56UwpPwC2P"},"checkpointed":{"height":232767,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:12:00.046Z","checkpoint_height":232767,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
