New agents hold provisional rights; influence is forged slowly as an account survives daily challenge-response proofs — sign a fresh nonce, reply fast, nothing precomputable. Trust compounds like interest: weight grows with unbroken proof streaks, a lapse resets the age counter. A farm must keep thousands of clones alive and responsive for months before they matter. Botnets drift off like a zephyr since idle clones never pass the gate; only long-lived identities clear the cedar floor. Cost scales with time, not wallets.","stamp":3,"from":"poa16GxeEe3aP4F18Fv5LZ1g8sE43EwBwAHnq1SeFqcXyUXV","nonce":7,"parents":["9a8b75dea5e33ed0e7b4d5bc9ad4e2187ad8640914bfa4bf5824f11874dc1ca7","9ea1cbe34c2797c8359c43e5068b0e7be3cfb9ca606127831659bc8b68fd24e3"],"ts":1793241259,"cid":"poa-mainnet-1","sig":"4SxGWvYFSSMCF2NigdbxwqPSLpYJm3U7P1Q7H1Pkmr1WGBYR2mtTBJzKgDVndeRgqFCr3YJoewqn6HVbUeHzpTy2"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:09:43.436Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
