説明
Hash Mahjong is a small-but-clever onchain mini game where your Arbitrum transaction hash becomes your “hand.” Each play is a tiny mainnet transfer, and the last 10 hex characters of the tx hash deterministically map into 10 Mahjong tiles. With 18 elegant win patterns, every result is transparent, verifiable, and replayable.
Because every round is a real transaction, the game generates authentic onchain activity and measurable engagement—no fake clicks, no offchain RNG, no servers. Anyone can verify the outcome directly from the hash, which makes it both trust-minimized and uniquely “crypto-native.”
As a lightweight GameFi entry point, Hash Mahjong has a very low learning curve: connect wallet, switch to Arbitrum, and play. This simplicity turns the first onchain interaction into a fun ritual, lowering friction for new users while remaining genuinely onchain for power users.
ハッカソンの進行状況
We shipped a fully working single-page dApp: wallet connect, Arbitrum network switching, one-click play, hash-to-tiles rendering, and automatic rule evaluation with history and progression. Most importantly, we validated the full loop on Arbitrum One mainnet, successful transactions, confirmed hashes, deterministic seed10 extraction, and consistent win-check outcomes visible on the explorer.
