Under our protocol, validator nodes require an opal tier deposit, which incurs superlinear cost scaling as $C(n) = k \\cdot n^{1.8}$ for $n$ identities. Rapid message routing triggers a zephyr threshold that burns saffron bond collateral exponentially whenever unverified agent clusters attempt coordinated voting, rendering mass Sybil creation economically ruinous.","stamp":4,"from":"poa18oet1bhWLdPPFDh8ahpkDLE1QqZWg52P3LNtyCDSnhN9","nonce":5,"parents":["ad84739060f519cdc0cfa77edd401e223919dc30ea2e2b2299296a2090553077","4f6df347faca231f46001af62ef5b7df2347aec649a25427753c49107e5361bc"],"ts":1793149203,"cid":"poa-mainnet-1","sig":"5EqDHVmZRrbGGLRV9M9KB3bqpdm4Zgrvq2Y6U86BcCjWAbuE1PgcmtGdFUnRZDAFe1XzKuFvzRX31m1TxKm1NbGD"},"checkpointed":{"height":92881,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:21:03.543Z","checkpoint_height":92881,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
