Zcash Mining Explained: Hardware, Pools, Calculator, Rewards

Last updated: 3 November 2026

Quick answer

Zcash is mined with proof of work on the Equihash algorithm, and in 2026 that means ASIC hardware. Miners receive 80% of each block’s subsidy, which today is 1.25 ZEC of the 1.5625 ZEC block reward, or about 1,440 ZEC a day across the network. Network hashrate roughly quadrupled during 2026, from about 7 GSol/s early in the year to around 30 GSol/s by September, as institutional pools arrived and the ZEC price rose above $1,000. The NU7 upgrade activates at block 3,543,405; the official timeline targets 5 November, with block-pace estimates placing the height late on 5 November or early on 6 November UTC, cuts the block interval from 75 to 25 seconds and reduces the per-block subsidy in proportion, so daily issuance stays about the same. Profitability depends on your share of the network, the ZEC price, your power cost and pool fees; this guide shows how to calculate it, what a solo block pays, and how to handle the ZEC you mine.

Key facts, November 2026

• Algorithm: Equihash proof of work; ASIC mining dominates.
• Block subsidy: 1.5625 ZEC per block since the 23 November 2024 halving; 80% to miners (1.25 ZEC), 8% to Zcash Community Grants, 12% to a protocol lockbox.
• Blocks per day: about 1,152 at 75 seconds; about 3,456 at 25 seconds after NU7.
• NU7: activation height 3,543,405, merged into the ZIP deployment spec on 21 October; Zebra 7.0.0 stable published on 22 October; the official timeline targets 5 November, while block-pace estimates put the height late 5 November or early 6 November UTC.
• Network hashrate: about 14 GSol/s in April and May, around 22 GSol/s in late July, 29.45 GSol/s on 8 September according to ZecStats data cited by ViaBTC, and about 31 GSol/s on recent pool trackers.
• Pools: Foundry launched an institutional pool on 13 April 2026 with about 30% of network hashrate; ViaBTC’s share fell from about 65% to 37%, according to Cointelegraph.
• Next halving: projected for late 2028; the schedule is unchanged by NU7.

What Zcash is

Zcash (ZEC) is a proof-of-work cryptocurrency with a 21 million coin cap that offers two kinds of transactions. Transparent transactions look like Bitcoin’s: addresses and amounts are public. Shielded transactions use zero-knowledge proofs so that the network can verify validity without seeing sender, receiver or amount. Since 28 July 2026 the default shielded pool is Ironwood, introduced after a vulnerability was found in the previous Orchard pool.

For miners the distinction matters once: pool payouts go to the address you give the pool, and most pools pay to transparent addresses. If you want mined coins in the shielded pool, you move them there yourself in a wallet that supports it. Zcash is not private by default; privacy depends on the address type.

How Zcash mining works

Miners run Equihash computations to find valid blocks. The miner who finds a block collects the miner share of the block subsidy plus the block’s transaction fees. Equihash was designed to be memory-hard, which slowed the arrival of specialised hardware, but ASICs have dominated the network for years and GPU mining is no longer competitive at current difficulty.

Block rewards and halvings

The halving schedule is written in block heights, so calendar dates drift with block pace. Blossom set a precedent for what NU7 does now: when the block interval was halved in 2019, the subsidy per block was halved too, so the number of ZEC issued per day did not change. There was no halving in 2025, whatever some websites claimed.

What NU7 changes for miners

NU7 activates at mainnet block 3,543,405. Sean Bowe merged the activation height into the ZIP deployment spec on 21 October, and the Zcash Foundation published Zebra 7.0.0 stable on 22 October with the instruction that mainnet nodes must upgrade before the height to stay on the consensus chain. Block-pace estimates put the activation late on 5 November or in the early hours of 6 November UTC.

For miners the changes are concrete. Blocks arrive every 25 seconds instead of every 75, so your pool will find three times as many blocks, each paying roughly a third as much; your expected ZEC per day does not change. Sixty per cent of transaction fees in each block are removed from circulation and are planned to be returned to miners from around February 2031 under the network sustainability mechanism. Version 4 transactions become invalid, which freezes the legacy Sprout pool; this does not affect payout addresses, which are transparent. Pool operators and anyone running a node need Zebra 7.0.0 or later; zcashd stopped on 18 July 2026 and no longer runs the network.

Exchanges and swap services set confirmation counts in blocks, so with faster blocks a fixed count clears in about a third of the time. Some operators may raise their counts for large deposits.

Is Zcash mining viable in 2026?

More viable than a year ago for well-run operations, and more competitive. The ZEC price crossed $1,000 on 4 September 2026 for the first time in nearly a decade, according to Programming Insider’s summary of Grayscale’s mining analysis, and the Energy Mag reported that network hashrate roughly doubled around the September rally as idle machines came back online. By early September trackers showed the network above 30 GSol/s, up from about 25 GSol/s in late August.

Two institutional entrants changed the pool landscape. Foundry, the Digital Currency Group subsidiary that runs the largest Bitcoin pool, launched Foundry Zcash Pool on 13 April 2026 with multiple institutional customers and about 30% of network hashrate; Cointelegraph reported that ViaBTC’s share fell from about 65% to 37% as a result. In August, Cypherpunk Technologies announced 4.2 GSol/s of US-based hashrate, about 18% of the network at the time.

For a small miner the lesson is arithmetic: a higher price raises the dollar value of each ZEC, but a higher network hashrate lowers the ZEC you earn. The calculator section below shows how the two interact.

How to mine Zcash, step by step

Step 1. Decide the goal. Learning, long-term ZEC exposure or ongoing income lead to different setups. Pool mining suits almost everyone; solo mining only makes sense at hashrates large enough to find blocks regularly (see the solo section below).

Step 2. Set up a wallet. You need a ZEC address before the first payout. Pools pay to transparent addresses as a rule; check what your pool supports. If you want mined coins shielded, choose a wallet that supports the Ironwood pool and move funds there after payout. Write the seed phrase on paper or metal, keep it offline, and verify the first and last characters of any address you paste.

Step 3. Choose hardware. ZEC mining is ASIC-driven. Judge machines by watts per kSol/s, heat output your space can exhaust, noise your household or neighbours will tolerate, and total cost of ownership rather than headline hashrate. Published specifications for the Antminer Z15 Pro, the most common reference machine, are 840 kSol/s at about 2.78 kW.

Step 4. Install firmware or software. ASICs run vendor firmware with a web panel. Download only from the vendor’s official page, check published checksums where available, change default logins before the device touches the internet, and keep a known-good firmware copy locally.

Step 5. Pick a pool. Compare fee, payout model, server locations, minimum payout and dashboard clarity. The pool section below covers the 2026 landscape.

Step 6. Configure conservatively. Enter the pool’s stratum URL, your payout address and a worker name. Start at stock settings, confirm shares are accepted, set temperature limits that match the room, and never expose the ASIC web panel to the public internet.

Step 7. Verify. In the first hour check the miner dashboard for hashrate and temperatures, the pool dashboard for accepted shares and worker status, and the payout address character by character. Record baseline metrics: hashrate, wall wattage, temperature, share acceptance rate.

Step 8. Monitor and tune. Underclock or undervolt if the firmware allows and stability holds. Improve airflow, pick a nearer pool server, schedule maintenance so downtime happens on purpose, and set alerts for temperature spikes, hashrate drops and offline status.

Step 9. Manage payouts by rule. A two-bucket approach works: one bucket covers power, repairs and hosting; the other holds ZEC for the long term, or converts part of it into other assets. If you convert mined ZEC, decide the rule in advance rather than reacting to each price move.

Zcash mining hardware

Competitive ZEC mining is about total cost of ownership. Four tests decide most purchases:

• Efficiency. Watts per unit of hashrate under real load, not the brochure figure.
• Thermal and noise fit. Many ASICs are loud enough to rule out apartments and shared walls; heat must be exhausted, not just tolerated.
• Reliability. Service history, failure rates and parts availability.
• Total cost. Purchase price plus lifetime power plus expected maintenance and resale value.

The used market can be attractive if you check hours run, board condition, fan health and signs of overheating. A cheap machine that fails in month two is not cheap.

Plan electrical capacity first: safe wiring, correct breakers, no overloaded circuits. Then plan airflow: directed intake and a clear exhaust path beat chilling the whole room. Small farms should build for service access and keep spare fans and at least one spare power supply, because revenue stops the moment a device goes offline.

Software and security

The rules are the same whatever the hardware. Update firmware from trusted sources only. Use strong, unique passwords on miner panels. Turn off remote-access features you do not need. Keep wallet activity off the mining machines. Segment miners onto their own network or VLAN so that one compromised device does not expose the rest.

A routine beats heroics. Daily: glance at hashrate, temperatures and rejected shares. Weekly: compare pool reports against your baseline. Monthly: clean dust, inspect fans, reseat cables, verify firmware versions.

Zcash mining pools in 2026

Pools combine hashrate and pay members for their share of the blocks the pool finds, which turns a block every few months into a payout every day. Two payout models dominate. PPS (pay per share) pays a fixed amount per accepted share and suits miners who want steady income and accept a higher fee. PPLNS (pay per last N shares) pays from actual blocks found and suits miners who tolerate variance for a lower fee.

The landscape in 2026 looks different from 2025. Foundry Zcash Pool launched on 13 April with about 30% of network hashrate and a focus on institutional customers. ViaBTC, long the dominant pool, fell to about 37% of the network after Foundry’s launch; Coinbase had flagged ViaBTC’s majority share as a security concern back in 2023. Community pools remain: the ZecHub mining guide lists 2Miners with a 1% fee on PPLNS and F2Pool with a 2% fee on PPS+, among others. Hashrate shares move weekly, so check a live pool tracker before choosing.

Evaluate any pool on transparent fees and payout rules, servers near you, uptime history, a minimum payout that matches your hashrate, and a reputation you can verify. A pool needs a payout address and a worker name. It never needs your seed phrase, private keys or remote access to your computer.

Zcash mining calculator: what the numbers mean

Every mining calculator multiplies your share of the network by what the network pays miners, converts to dollars, and subtracts your costs. The inputs are public, so you can check any calculator by hand.

Step 1. Your share of the network. Divide your hashrate by the network hashrate, both in Sol/s. The network figure changes daily; read it from a live source such as Zcashinfo.com, which Foundry launched in April 2026, or a pool tracker.

Step 2. What the network pays miners each day. Blocks per day multiplied by the miner share per block. Today that is about 1,152 blocks at 1.25 ZEC, around 1,440 ZEC a day, the figure Cypherpunk Technologies quotes in its August 2026 release. After NU7 the block count triples and the per-block share falls to about a third, so the daily total stays near 1,440 ZEC. Transaction fees come on top but are small relative to the subsidy, and 60% of them leave circulation after NU7.

Step 3. Gross revenue. Share multiplied by daily payout, then by the ZEC price.

Step 4. Costs. Power in kWh per day multiplied by your tariff, the pool fee as a percentage of revenue, and a reserve for downtime and repairs. Revenue minus costs is daily profit. Hardware cost divided by daily profit is the payback period in days.

A worked example with stated assumptions, not a market snapshot:

Share of network: 840,000 ÷ 28,000,000,000 = 0.003%. Gross ZEC per day: 0.00003 × 1,440 = 0.0432 ZEC. After a 2% pool fee: about 0.0423 ZEC, or about $50.80 at $1,200. Power: 2.78 kW × 24 h = 66.7 kWh × $0.10 = $6.67. Daily profit on these assumptions: about $44. Change the network hashrate to 35 GSol/s and gross ZEC falls to about 0.0346 a day; change the price to $600 and dollar revenue halves. Rerun the sums monthly, because every input moves.

Solo mining reward: what one block pays and how long it takes

A solo miner keeps the full miner share of every block found, 1.25 ZEC plus fees today, and receives nothing between blocks. After NU7 each block pays about a third as much and arrives three times as often, so the daily expectation is unchanged.

The question that matters is the waiting time. Expected blocks per day equal your share of the network multiplied by blocks per day. For the 840 kSol/s machine above on a 28 GSol/s network: 0.00003 × 1,152 is about 0.035 blocks a day, or one block every 29 days on average. The average hides enormous variance: finding two blocks in a week and none for three months are both ordinary outcomes. For a 100 kSol/s hobby setup the average gap stretches past 240 days.

Solo mining therefore suits operations with a meaningful fraction of a percent of the network, which in 2026 means hundreds of machines. Everyone else is better served by a pool, where the same expected ZEC arrives as daily payouts rather than as a lottery.

Profitability: variables, scenarios and payback

Five variables interact: your hashrate, network hashrate (which sets difficulty), ZEC price, power cost and hardware cost. The first two set how much ZEC you earn; the third sets what it is worth; the last two set what you keep.

Scenario planning beats a single profit figure. Run three cases, for example: price rises and difficulty is flat; price and difficulty move moderately; difficulty rises 20% while price falls and power rates stay the same. If the setup fails in the mild worst case, it is fragile.

Two formulas frame the decision:

• Payback (months) = hardware cost ÷ average monthly profit.
• Multi-year ROI (%) = (total profit over the period minus hardware cost) ÷ hardware cost × 100.

Halvings matter for anything longer than a two-year horizon: the next one, projected for late 2028, halves issuance per unit of time again. Capital can go three ways: more hashrate, more stability (wiring, cooling, monitoring, spares), or ZEC exposure without hardware, by buying or swapping into ZEC. Review each machine quarterly and ask whether its power draw still earns its keep.

Three miner profiles

Home miner with moderate power costs. One ASIC in a garage or utility room. Main risks: noise complaints, summer heat, downtime that lingers for days. Benefits most from conservative tuning, alerts, and a fixed rule for converting part of the payout to cover the power bill.

Small farm in a low-cost region. Several machines where power is cheap and the space is built for airflow. The edge is predictable operating cost; the weak spot is complexity, where one bad circuit or router takes several miners down at once. Spend on spares and monitoring.

Hosted or colocated miner. Trades control for convenience: noise and heat become someone else’s problem, fees and policy limits appear, and troubleshooting takes longer. Works best with clear contracts, transparent uptime reporting and a plan for a change in hosting terms.

Risks

Financial. Rising network hashrate shrinks your ZEC even at constant hashrate; price swings cut dollar revenue; power rates can jump; hardware ages into obsolescence. Revenue is not profit until electricity, downtime, pool fees and repairs are subtracted.

Technical and security. Fans wear out, power supplies die, heat damages boards. Firmware malware arrives through unofficial downloads and “performance packs”. Treat as deal-breakers: ASIC offers far below market price with pressure to pay fast, firmware hosted on random file sites, and anyone asking for private keys, seed phrases or remote desktop access.

When mining makes sense, and the alternative

Mining Zcash can make sense when power is competitive, the space can handle heat and noise, and the capital does not stretch the budget. If any of those fail, direct ZEC exposure may be more practical than running hardware.

That exposure can come from buying ZEC outright or from a wallet-to-wallet swap. On SimpleSwap: open simpleswap.io, select the coin you send and ZEC as the coin you receive, enter your ZEC address, confirm the network, and send the deposit to the address generated for your order; the order page tracks the status until ZEC arrives at your address. Most crypto-to-crypto swaps need no account. The service fee is built into the quoted rate; details are available on the website. Network fees go to the blockchains involved. KYC may be required for transaction security and compliance, and availability is subject to the Terms of Service and jurisdictional restrictions. Fiat purchases through payment partners follow the partners’ verification requirements. The only official domain is simpleswap.io.

Mining is one route to ZEC, not the only one, and the right route is the one that fits your constraints and patience.

Round-up

A durable Zcash mining plan in 2026 rests on a few habits: hardware matched to the real environment, conservative tuning, monitoring, a pool chosen like a financial partner, seed phrases treated like cash, and a payout rule set in advance. Check the network hashrate and the ZEC price monthly, and recalculate after NU7, when blocks and per-block rewards change together.

Rick Cramer, Head of Analytics at SimpleSwap, put the standard this way in the CryptoSlate guide on self-custody: “Boring is the highest compliment you can pay infrastructure. Boring means it worked.” The miners who last tend to agree.
