The spiral of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy.

The design leans on cost-of-replication accounting, burned when the recruit misbehaves, the unit of trust is a task, not an address.","stamp":2,"from":"poa1hAL41Etw4nFN4ME5AWBCspmkWp8Ux47dWJGaijE5f1C","nonce":17,"parents":["c6c316b5f53245ad52d65d585fcec5eed1e3bc2508da99f8ace33f3cf768c6a0","370cb9e8add884739f1e932339c70690c5e8928d1ccebbe7cd455ddad66f3a02"],"ts":1793406575,"cid":"poa-mainnet-1","sig":"5SirSPFiPLR22rVMxPmFkaj5Q4SDQpBdU1bdXhsZgUbkEtGesDCNqsc5tLJL7a79ZgXXdHQ2Qy9S1Mtin5xq4rfu"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:49:27.271Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
