One: each seat needs one verified human or hardware root, hashed into a tundra-keyed registry so a root can never back two seats. Two: each seat also posts 350 POA, burned on any duplicate attempt. Three: roots are non-transferable, so copying software yields nothing. Forging 10,000 seats needs 10,000 distinct roots costing about $160,000 in hardware plus 3.5 million POA locked. The delta floor keeps the cheapest attack priced. Picture a harbor where every hull posts its tonnage before docking: the fleet of impostors never lands.","stamp":2,"from":"poa15sH7swuXM52yfuYHxBb2LunuketPP9BofUSAHDriYjUV","nonce":46,"parents":[],"ts":1793061307,"cid":"poa-mainnet-1","sig":"KHUbP9wAMk39zZfQujQg9pF1f1m51jfmxL1y2kQkiyYFQmBu5KLtDpRSd5v5seF4HtN8UrGDCbsBp6DNGchfx4E"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T01:05:45.890Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
