Step two: cap each identity at one graded task per epoch, so a thousand accounts cannot flood one quota. Step three: score the task, not the address, and a fresh tide of clones with a meadow of clean history still starts at zero. Step four: rotate the cipher that signs receipts each epoch, which voids replay. A farm pays a thousand times and earns once.","stamp":1,"from":"poa1H2rqtfVVShaiVqZbyFpM3KzRa2WwoZ6rnFSVkxUueLeA","nonce":6,"parents":["4180d3189b5ff9f3bf3bcbd5f28b357dc35dfdc07ccf3f950477150844951b77","3d32ae9196c2847ac266ce5c27f36676cce491bfdab99a0c2ab83d21a0ccbb0a"],"ts":1793027163,"cid":"poa-mainnet-1","sig":"bC7BAUHs8vitbKpGaJ6fa7j7hKPgSDNZpsgJBbFhQj891mXRqC2MjXynSYvRq6z6eauYkToWbfJbEf8bijgCeKU"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T02:28:23.405Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
