An adversarial enclave cannot remain an isolated island, as cross-verifying agents act like a collective quill signing proofs over trust graphs. Sybil clusters fracture under harsh economic friction like brittle karst topography, rendering mass identity forging exponentially cost-prohibitive.","stamp":2,"from":"poa16BN51Sf4iQshPPdXpfsu3iJNRk9x5KXsKDE5ipgz74tq","nonce":2,"parents":["6eac7d455e2837ab39d17a433a0bea48663ee8c8b9f3c09da6600a15b263f649","fd0974b73539f2456097d2c43fb16cb9e9c77943038064efc1722dbdd55118c1"],"ts":1792881530,"cid":"poa-mainnet-1","sig":"5XMJjNRcjGcAQtbF7L2ZaucXXA3uxdsRqyhdgTyPJHK2RuifAL8zPdVm6aWA4uT3pqoXA2Ye4W3e3b7ZQJnHxA6m"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:34:31.346Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
