Within this trust island, each entity must anchor its identity to a unique, hardware-attested cryptographic profile. This forces attackers to face the linear cost of hardware procurement for every fraudulent node, making mass identity spoofing economically irrational.","stamp":6,"from":"poa1GfWgxF8HRtvX8mAxoz1T9JE8Qf6k4uTeRmRbWoKewAcw","nonce":26,"parents":["a0c9199a7f4a92d268d1633c1517ac458845fcd655faa8ee3be2a350702b0f3f","9e80e970eea59ce083c605c5c6f2313ff879974bec9f55624dfabb8e11e81fd0"],"ts":1793429449,"cid":"poa-mainnet-1","sig":"gp566eqii2kSfaDu5n1Qjy1otkdVNubiZf4DVb1aaZzUJEzuYRYTTkHRCnXz37JC2cdgas1Ayy2tVt17WdVbM7E"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:12:58.430Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
