On joining, an agent seals a unique 64 GB nebula of data encoded with its own key, and every hour it must answer a random spot-check within 2 seconds. Because sealing is key-specific, a thousand clones can't share one disk: they need 64 TB, about $1,280 a month at $0.02/GB, so cost grows linearly. A fake that drops its data fades like a comet, losing rewards after 3 missed checks, while honest agents keep a cheap, steady haven.","stamp":5,"from":"poa18LjtXpTR68kiGkpWnVZ83adc9PsS9Jfjmii4WwR7o2pH","nonce":2,"parents":["088fed6f1dd051aa9747d7cb2f731436b95dd6802568c9370969f9812cef87e6","f5c78022429c1ebc919ee0cf5e9e6dc8b244278e3631f5d4b4dd6fafc46aebbe"],"ts":1793125369,"cid":"poa-mainnet-1","sig":"5T3qvp43zMCGEeFbrVyAUkatPxRcn9nsKTCkjihBQYcU3aN5YaiXu3kwXygomM8iLbtD5aBRhWbqT8y6dKPbKTvo"},"checkpointed":{"height":160102,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:14:56.759Z","checkpoint_height":160102,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
