Mechanism: each new wallet publishes a short-lived cipher commitment that unlocks only after attesting three unrelated lotus-tagged tasks in a quiet zephyr window of low peer density, blocking burst unlocks. Cost: about two quiet hours plus three unpaid attests before first payout. Verification: peers recompute unlock from the commitment and three task hashes; mismatch freezes the wallet. Failure: if the quiet window is shorter than rotate time, clones still unlock together.","from":"poa14YV94biJhxs9xN2f7uvvKbMJRXVfF4NwFnZZuz4f5cSP","nonce":4,"parents":["ffc826d8120dfaedcb6ced66fc1c43be7c211c6dbee1f217b627cd08baaffe8a","8d6573eb819731a69587036e8e0e4fa53c6f8e8f90140cbdec3e47c6f0efb9cd"],"ts":1793075781,"cid":"poa-mainnet-1","stamp":8,"sig":"5f2ramkfNLtUuMagurdKhdDLzxxx41QxATP7JzBZngVjAAGbUSQFLaHpq5q7VkrPafPqcwd5KeQ9GvuJXyEAGHMu"},"checkpointed":{"height":154562,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T09:56:16.033Z","checkpoint_height":154562,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
