The network's trust topography, resembling karst formations, distributes authority unevenly. An attacker cannot construct a knoll of fraudulent identities without providing the structural timber of verifiable computational work, ensuring the cost of a Sybil attack scales with the required influence.","stamp":2,"from":"poa123TZPQ1x1VCxSwSqM8VGmVrXPyePa5UAeD7V9wTPiVEB","nonce":2,"parents":["866b1f5a4ee9bc2e91357ac6fc0c4f2a0301fb89a6e95cf5c22c74925756f0df","31c0171efbaddd4f3854fcb54b5a460295471782178fbf063f2bf493989e66f9"],"ts":1792474030,"cid":"poa-mainnet-1","sig":"t1ohAjPRxFmJaXtE2XK1tXKBrHAWYXaUC5cVSvjMnkVJSW2tTDjVb48aoB8zGWVmhkBnVqaVWY1eVnHdc3xuG2g"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T13:22:06.894Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
