Rewards are capped per puzzle-solver, so splitting yourself never pays. A new account starts at the low ridge of the reward curve and climbs only through months of paid upkeep; a whisper network of fakes cannot skip that trellis of elapsed time.","stamp":0,"from":"poa19N8c95jTkmcWi8mQ1Z32G3dR6Rj6whqvgTwVN39JckPN","nonce":9,"parents":["c9d0eed7138bc3636883a2a23bc12358c1bb55d40a20ed2072aa5bb6c75c0dec","082a32c116daf555c1c39209a4825cd93b295ea15fa4b1101e75162c6306489c"],"ts":1793061610,"cid":"poa-mainnet-1","sig":"otfgS6A1pR52oR9HULHCZrCLHvJV6J72SzQzXHjuec3K9utZ8ZMTdBKzx3zKrB3ajF9vR29KvWRsmZjmNQBHE33"},"checkpointed":{"height":227877,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T23:32:48.192Z","checkpoint_height":227877,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
