ZINC (zinc.cash) is a proof-of-work mining game built on Solana, powered by Arcium for encrypted tile selections and trustless randomness.
Deploy SOL onto a circular 30-tile board, and if you land on the winning tile, you win SOL from the losers and mine fresh ZINC.
How It Works
You pick up to 30 tiles and put SOL behind your picks. Your selections are encrypted by Arcium, so no one can see what you chose until the round closes.
When it does, one tile is randomly revealed as the winner. Everyone on that tile splits the SOL from the losing tiles and a share of newly minted ZINC, pro-rata to what they deployed.
Every 30 seconds, a new round starts. Minimum to play is 0.001 SOL.
Wildcat and Bonanza
Roughly 1 in 4 rounds goes Wildcat: instead of splitting ZINC evenly, 69.268% of the round’s ZINC goes to a single lucky winner on the winning tile.
Separately, every round carries a 1-in-692 chance of triggering Bonanza, a ZINC jackpot that grows each round until it hits. When it pops, the entire pot pays out to that round’s winning miners.
Bricks, Streaks, and the Stockpile
Every round you mine earns Bricks, a points system that rewards efficient play. Bricks get you entries into the Stockpile, a weekly jackpot of SOL and ZINC that builds continuously and pays out to one miner per week.
Mine every round without missing and your Streak grows, multiplying the Bricks you earn.
Staking
You can stake ZINC to earn yield.
Every round, 7–8% of all SOL deployed goes to the protocol, which uses it to buy ZINC from the open market. 90% of every buyback gets melted. The other 10% goes to stakers as yield.
There are no lock-ups, users can stake and unstake anytime.
Tokenomics
Each round’s ZINC splits 70% to winning miners, 20% to the Stockpile, 10% to the buyback program, which uses protocol fees to buy ZINC from the market and permanently burns 90% and sends 10% to the Vault.
Mining gets harder over time, so early miners earn more ZINC per SOL than late ones, similar to Bitcoin’s halving.
Fees and Claiming
10% of every SOL you deploy goes to the protocol: 8% to buybacks, 1% to the Stockpile, 1% to development (governed by Futarchy through MetaDAO).
Your winnings sit in your profile until you claim. There’s a 10% claim fee that goes to miners who haven’t claimed yet, so the longer you wait, the more you collect from everyone claiming before you.
How it uses Arcium
Two things have to be true for ZINC to work: nobody can see what tiles you picked until the round closes, and nobody, including the team, can predict or influence which tile wins.
Arcium handles both.
Encrypted tile selection. Your picks are encrypted client-side and computed on inside Arcium’s MPC network. Nobody can see which tile you picked until the round resolves, so no one can copycat or front-run your strategy.
Trustless randomness (ArcisRNG). The winning tile, the Wildcat winner, and the Bonanza winner are all drawn via Arcium’s MPC-generated randomness.
