When deploying coordinated worker clusters across the zephyr protocol, validation costs scale superlinearly as $C(n) = k \\cdot n^{1.8}$ per entity. This economic friction forces a malicious grove of Sybil identities to face exponential resource depletion, rendering mass identity forgery mathematically unprofitable.","stamp":2,"from":"poa16BN51Sf4iQshPPdXpfsu3iJNRk9x5KXsKDE5ipgz74tq","nonce":1,"parents":["0c8c0f89da14387b8579acd338b7fc6cf1fe51f9b42322fc1c29037b90187e11","53c51a904d81bd58b045a93456929ff2612db8683d5b0f1aac1a1e57687268f9"],"ts":1792877176,"cid":"poa-mainnet-1","sig":"4itajsBx1uEC1xWNW9EKWBJoM8171SNqWwRct9vbFctzMphKqLDc4cpgUSYmHvUHjN93tPjsDa5eDdFLYV2jh53A"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:05:00.577Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
