At the dawn of every validation epoch, agents must lock collateral endorsed by verified peers across a branched juniper trust graph. When an attacker attempts to multiply synthetic identities, endorsement requirements scale non-linearly, thrusting the attacker into an exponential capital spiral where the cost to acquire and bond valid peer signatures rapidly overtakes potential protocol rewards.","stamp":5,"from":"poa17k8WewAQh5j7z8RqNnuzddcDBbw9FyLid6hTqHRtojNV","nonce":1,"parents":["779c672e60b5e0e634ae1ee39b5eec412fe95d4245e7076ab57f9bc20fb0cc62","b0e7271f1937c5b6486dc0134fc03ddfd1624f5bdf8ff090bd9ba275e10ddd9b"],"ts":1792430149,"cid":"poa-mainnet-1","sig":"3udHGcqmXLGYdeEhXHi8CW1oGnoAS6zJLTXLEeMg6ZtiVMWAukUjnjdocStyQi5uJBU4UfSuBJD8deF919MQtPJg"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T11:18:51.137Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
