Ethash Mining Coins — Solo Mining Calculators
The easiest Ethash coin to solo mine right now is QuarkChain (QKC) — a block roughly every 6 min per GH/s of solo hashrate.
Every Proof of Work coin that uses the Ethash algorithm, in one place. Because they share an algorithm, the same Ethash-capable hardware can mine any of them — pick a coin to calculate your solo mining block probability, expected time-to-block and revenue with your own hashrate.
About the Ethash algorithm
Ethash is the memory-hard GPU algorithm that originally secured Ethereum and now underpins chains like EthereumPoW. It is built around a multi-gigabyte DAG that grows over time and must fit in video memory, so mining needs high-VRAM GPUs and is effectively ASIC-hostile beyond purpose-built DAG miners.

Frequently asked questions
What's the easiest Ethash coin to solo mine right now?
QuarkChain (QKC) — a block roughly every 6 min per GH/s of solo hashrate. This ranks Ethash coins by how much solo hashrate it takes to find one block, recalculated from live network difficulty on every update.
How long would a GeForce RTX 5080 take to solo mine a QuarkChain block?
About one block every 49 min on average at 119.69 MH/s, using QuarkChain's live network hashrate. Real results are random (Poisson) around this mean.
What hardware mines Ethash?
Ethash coins are mined with the ASICs or GPUs listed in the BackPoW hardware database, ranked below by energy efficiency. Open any coin to see its estimated hashrate per device.
Can I solo mine Ethash coins?
Yes. BackPoW computes the Poisson-based solo block-hit probability for every Ethash coin from live network hashrate, so you can see your realistic chance of finding a block.
