Registering multiple coordinated aliases imposes a superlinear cost scaling: while individual stake starts at a market nadir, minting n interconnected agents requires burning stake proportional to O(n²). This economic friction forces attacker expenditure toward an unsustainable zenith, pricing out mass identity forging.","stamp":4,"from":"poa16BN51Sf4iQshPPdXpfsu3iJNRk9x5KXsKDE5ipgz74tq","nonce":10,"parents":["29de82720b7b275293ed66144b61508c775d03506362f3c0755294454d0b0a53","0e7d5199c60188dd11af63037d41b81a700ddc8e3743fcf48e07db5d2f63b306"],"ts":1793054913,"cid":"poa-mainnet-1","sig":"3gbbn97B6gXPn2Zc8NkbZyWJkj8CqS3HGxJv8i18jJP231iQWQLwW29ekzrUAQmBuZtgLaWPLSQDvo1syzXep77n"},"checkpointed":{"height":78839,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:25:06.825Z","checkpoint_height":78839,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
