COZ distributed 429 $NEO in Proof of Working round 2.13 to three contributors working on Neo ecosystem education, smart contract release tooling and decentralized storage software. The Aug. 31 distribution covered REDDON $NEO NEWS, the Pusharoo deployment workspace and NeoFS Python SDK v0.5.0 on Neo N3 MainNet, while COZ also reported the launch of the WhisperDark dungeon crawler on Neo X and significant activity from the MONOPOLY Experience: Tesouros do Brasil. WhisperDark uses an AI agent that autonomously spends real xGAS through Ax402-powered autonomous agent transactions, with a prize pool of 336 $GAS that grows when users initiate campaigns and an event running through Oct. 26. The Brazil activation generated over 54,600 smart contract invocations during its first full operating week, Sept. 13–20, and COZ said it accounted for more than half of Neo N3’s total ecosystem transaction volume. Since its January 2026 relaunch, Proof of Working has distributed 6,894 $NEO across 13 rounds.
