Frequently asked questions

What is a solo mining calculator?

A solo mining calculator estimates how long it will take you to find a block on your own, and your probability of success over time, based on your hashrate and the coin's live network difficulty. BackPow covers 130+ proof-of-work coins.

How accurate are the block-chance estimates?

BackPow uses the exponential/Poisson model that correctly describes memoryless proof-of-work hashing, so the probabilities reflect real statistical odds rather than a naive linear guess.
