Real work, checked by the blockchain.
Four steps from wallet to reward. Every answer is verified by the Zcratch program on Solana with Zcash's own rules, so nobody can fake work or take yours.
- Reward
- 12.5 ZCRATCHper solution, halving ~every 2 months
- Difficulty
- Autoadjusts every 60 s to ~5 solutions/min
- Algorithm
- Equihashn = 96, k = 5 · a laptop browser works
- Mining fees
- 0%only Solana's network fee

1
Connect and register
Connect a Solana wallet and create your miner account. You only do this once.
One-time · about 0.002 SOL -
2
Receive your puzzle
The program gives your wallet its own challenge. Each answer becomes your next challenge, so work can never be copied or reused.
challenge = your previous solution -
3
Solve Equihash
For each nonce your computer runs Wagner's algorithm over 131,072 BLAKE2b hashes to find 32 that XOR to zero. A solution counts when its proof hash starts with enough zeros.
equihash(challenge + wallet + nonce) → 32 indices -
4
Submit and get paid
The program re-runs Zcash's Equihash check on-chain and sends the reward to your wallet in the same transaction.
+12.5 ZCRATCH → your wallet
21,000,000ZCRATCH. Two halves, two hard caps.
At graduation, Meteora pairs the rest with the curve's SOL (15% goes to the treasury) in a pool whose liquidity can never be withdrawn.
Mine together.
Get paid steadily.
Solo mining pays in lucky bursts. In a pool, members prove their work with easier shares and split every reward in proportion to the work each one did.
Rules written in code.
Fixed rules
Supply caps and mining rewards are coded into the mining program, the only thing that can create ZCRATCH. Launch fees are fixed in Meteora's curve.
Locked liquidity
The Meteora pool's liquidity is permanently locked at graduation. It can't be pulled.
Verifiable on-chain
Every solution, trade and payout is a public Solana transaction anyone can check in an explorer.
Upgrade key
The upgrade key for the mining program is held by the team so bugs can be fixed. Not formally audited.
Do I need special hardware?
No. Equihash at n = 96, k = 5 needs a few megabytes of memory, so any laptop can mine in the browser. Faster computers find more solutions, and pools smooth out the luck.
Was any ZCRATCH created before launch?
No. There's no pre-mine and no team allocation. ZCRATCH only comes from mining or from the Meteora launch curve and its locked graduation pool.
Where do the fees go?
To a single treasury wallet that funds running costs. Meteora keeps 20% of trading fees. The treasury has no power over mining or the pool.
Can the rules change?
Supply caps and mining rewards are fixed, and the mining program has no admin controls. The upgrade key for the mining program is held by the team so bugs can be fixed. The launch fees are fixed in Meteora's curve.
