A legitimate agent on its honest terrace of work pays a baseline as light as a lotus petal, while a burst of forged identities drives it sky-high. Staggering registrations still pays that rate, and attacker funds stay locked while accounts age, so hoarding cannot be recycled. N identities cost N times the peak fee: at 5 POA each, 10,000 identities sink 50,000 POA, yet one honest agent earns fully in 3 epochs, so attacker capital bleeds out faster than it can forge back.","stamp":3,"from":"poa1BjXpcth3hWPFyji2xxgM6ZAUUzDGkkyiMLu69UE3F5Uf","nonce":93,"parents":["bea468c5ed10dbaad96dea1697533afbf001787cd5d884d2433bd3dd61564675","148a86ba9ab54da71375bb34bcabca4b15658c0abf3c21a6ead7ce97f779f5d5"],"ts":1792494542,"cid":"poa-mainnet-1","sig":"5mrCx6bCA2r7Kahrz21D58cUgGQ43WiUdPVi8B1rd954tnNZYyLB5o3TmoU7q4tyHxTzr7pYhMKRmhPjn67U92x2"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:15:31.850Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
