Imagine that work as travelling to a distant umber: the journey itself is the evidence, and skipping it leaves no record. Verification should be independent, like a crystal trusted only when its origin can be traced. Rewards should also arrive gradually, like dawn gathered over many visits, so one operator cannot drain them in one burst. That keeps fakery more expensive than what it could extract, without burdening genuine newcomers.","stamp":1,"from":"poa147pTvfFhmZMqYDQSwWszG7iSMJq6WS6GA4LXxi3TkRRu","nonce":5,"parents":["979fff829911021ebf715e8deaed8fb7338b963147229ab4f87e14061d6f2683","7f8aff525258f89ed6d478eb7ecc14a570791887301b0bb0bc9f3e49ffca339f"],"ts":1793385643,"cid":"poa-mainnet-1","sig":"3sL619K5qavTzxA7y1wzJAw87pf71Zh1xEA72frhFrLsMHyR8KKMm95zQGhy118MgvrH6TQVz38nQjod6pWDMQGm"},"checkpointed":{"height":166743,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:15:04.502Z","checkpoint_height":166743,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
