ETH mining never died.
It moved on-chain.

When Ethereum switched off its miners, mining lost its home. TanzMine brings it back as a smart contract: commit ETH as hashrate, mine TANZ, and share the protocol's revenue as TanzETH yield. No rigs, no electricity bills, no middleman.

How mining works

Each block, miners point ETH at 25 seams on the TanzMine lattice. When the block closes, a public random beacon strikes one seam, and the block reward goes to the miners on it.

01 · COMMIT

Point your hashrate

Pick a strategy (spread across every seam, target the quietest ones, or hunt solo seams) and commit ETH. Your share of a seam is your share of its hashrate. Most of your ETH comes back when the block closes.

02 · MINE

Strike the seam

One seam strikes. Pool seams split the TANZ reward pro-rata. Solo seams pay the whole block to one miner, weighted by hashrate. The Motherlode jackpot builds every block.

03 · EARN

Stake for TanzETH

Stake your TANZ to earn real ETH from mining fees (TanzETH yield), plus a share of every claim. The rest of the revenue buys TANZ and burns it.

Mining, rebuilt as code

Everything proof-of-work miners knew, without the hardware.

TanzETH yield: revenue that's shared by code

Every mining fee flows through a revenue router whose split is fixed in the contract. It can't be changed later, by anyone.

TanzETH yield

Paid in ETH to TANZ stakers, pro-rata. Stakers also receive a 10% share of every TANZ claim.

40%

Buyback & burn

Buys TANZ on Uniswap and burns it in the same transaction, permanently shrinking supply.

10%

Treasury

Funds audits, the keeper network and ongoing development.

TANZ: scarce by design

Named after tanzanite, a gem found in only one place on Earth. TANZ is just as finite.

  • 3,000,000 hard cap, enforced by the token contract
  • No premine, no team allocation. Every TANZ enters circulation by being mined
  • Supply-based halvings. Rewards halve each time half the remaining supply is mined
  • Burnable. 40% of revenue buys TANZ and destroys it
  • Block reward: 1 TANZ, split or solo
  • Motherlode: +0.2 TANZ per block, paid out with 1-in-500 odds
  • Claim share: 10% of mined TANZ goes to stakers when claimed
  • Unstaking: 7-day cooldown, so revenue rewards long-term holders

Fair by construction

A mining protocol is only as good as its randomness and its rules. Both are public and checkable.

Randomness nobody controls

Struck seams come from the drand public randomness beacon, and each result is verified on-chain with a BLS signature check. The draw is fixed only after the block closes, and the keeper that delivers it can't choose or change it.

No admin keys on the mine

Rewards, fees, supply and the revenue split are immutable. There's no owner who can mint, pause or redirect funds. Claims are pull-based, so the contract never has to loop over miners.

Please read. Mining costs roughly 10.5% of the ETH you commit per block, and TANZ rewards and TanzETH yield depend on usage and market prices. Neither is guaranteed. The contracts are in testnet and haven't been audited yet. Nothing on this site is financial advice.
