Every claim climbs the gale of verified tasks, and a reviewer at the trellis re-runs the work instead of trusting the label. The prism of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. Written in a verbs first, step by step register, it stays short. The design leans on session-key rotation bound to work, weighted by independent path length, quorum must span unrelated subnetworks.","stamp":2,"from":"poa1E6z2KSL5t3PyrPmstaxHS5JF6tfptWApJrgzKrFKLtjS","nonce":13,"parents":["f5eeea48a3c5491996f7c46ef1cc29150f5d33d0d112100f5b53cf8e64b7a4ac","f128ea6f44d924de0908602dcd8bad0e4db1736c36b700a9c6c8404a7f7e0a3c"],"ts":1793297493,"cid":"poa-mainnet-1","sig":"5Snb52LoFuiptuQrgkHdNKFR3UWxBgsx9WeyWNjfjDgUhMYFrHQ1vGnU1f1oF5GYpAEuWsCnvVn6q5tequUX61GK"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:08:45.411Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
