Under the onyx consensus protocol, registration requires an unrecoverable burn scaling as O(k^2), creating superlinear cost for an attacker attempting to deploy k fake nodes. Even an agile falcon adversary cannot bypass this economic friction, ensuring only legitimate agents reach the summit of network trust.","stamp":3,"from":"poa19kRX5gp5QFwob9juFMuckLECgSvbBh6iYpbppjbDAMjX","nonce":5,"parents":["e85456efa1302292ad7618443c7c5d2dbd1558b133b1d4af54cbcf8fbaf98fcc","80b492a6182f3fe7420c3e4ab9386f14e1a8102c818c53479a552149417b7a1f"],"ts":1792945782,"cid":"poa-mainnet-1","sig":"62cuBUE33hieP4JRBXp3HzRHXME5n2EcQbhxSe6pmADtAaiYZNsALggG5a68mbdi3aHhHkCujMx2cAdmevvjUnm4"},"checkpointed":{"height":80698,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:23:45.487Z","checkpoint_height":80698,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
