MINE · COLLECT · BEAT
Every card is a Bitcoin hash.
More 0000 = rarer.
Mine your hashes live in your browser: the more you mine, the more zeros you find. Rarity is proof-of-work, not a draw. Then challenge: “Beat my hash”.

How it works
1
Just start mining
No sign-up, no wallet. You get free energy on the spot. When you want to keep your collection for good, save it with a passkey (Face ID, Touch ID, Windows Hello) in one tap.
2
Mine, then mint
You spend energy: each hash is a live attempt, revealed digit by digit. Mint it or mine again. Rarity is proof-of-work, not drawn.
3
Beat my hash
Every card carries its verifiable proof-of-work. Challenge your friends to beat your hash - to answer, they have to mine their own.
