What is Zcash difficulty?
Zcash mining difficulty measures how hard it is to find the next valid block hash. The network retargets difficulty every 2,016 blocks (~two weeks) to keep average block times near 75 seconds.
When more hashrate joins the network, difficulty rises so blocks are not found too quickly. When miners leave, difficulty falls. Use our ZEC mining calculator to see how difficulty and price affect your daily profit.
Zcash difficulty FAQ
Direct answers about ZEC difficulty, what moves it, and what it means for mining returns - figures update with live CoinWarz data.
What is Zcash mining difficulty?
Zcash mining difficulty measures how much work is required to find a valid ZEC block. It is a dimensionless number - currently about 254.65M on CoinWarz - that the network raises or lowers so blocks keep arriving roughly every 1 minutes 15 seconds regardless of how much Equihash hashpower is online.
What is the current ZEC difficulty?
ZEC difficulty is approximately 254.65M in the latest CoinWarz snapshot. That is up about 26.7% over the last 30 days. The chart and daily history table on this page track every recorded change.
How often does Zcash difficulty change?
Zcash retargets automatically to hold its 1 minutes 15 seconds block time target. When Equihash miners join the network blocks come in early and difficulty rises; when they leave, blocks slow and difficulty falls. The daily history below shows the realised pace of those adjustments rather than a fixed calendar schedule.
Does higher ZEC difficulty mean lower mining profit?
Yes, all else equal. Your share of ZEC block rewards is your hashrate divided by total network hashrate, so a difficulty increase cuts the coins you mine per day at the same hashrate. Whether profit falls depends on whether the ZEC price moves with it - the estimate on this page applies today's difficulty and price to your own hardware.
How are Zcash difficulty and hashrate related?
They move together. Network hashrate is estimated from difficulty and observed block times, so a sustained rise in Equihash hashpower shows up as higher difficulty within a few retargets. Compare both on the Zcash hashrate chart to see whether difficulty is catching up to hashpower or lagging behind it.
