Zcash uses the Equihash proof-of-work algorithm. On Mining Rig Rentals, Zcash mining should use the Equihash/zcash algorithm category.

Do not confuse Zcash Equihash with other Equihash variants such as Equihash 144,5, Equihash 192,7, Equihash 210,9, or other parameter sets. These are different algorithms and are not interchangeable.

If you select the wrong Equihash variant, the miner may connect but submit rejected shares, invalid shares, or no accepted shares at all.


Zcash uses standard Equihash, not Equihash 144,5

Zcash mining uses the Equihash algorithm, but not every Equihash listing is suitable for Zcash. Zcash documentation identifies Equihash as its proof-of-work mining algorithm, while Mining Rig Rentals separates Equihash/zcash from other Equihash variants.

For Zcash, use the Mining Rig Rentals category intended for Equihash/zcash.

Do not use:

  • Equihash 144,5 / ZHash,
  • Equihash 192,7,
  • Equihash 210,9,
  • Equihash 150,5,
  • or any other Equihash variant unless the pool specifically requires that exact algorithm.

The algorithm selected in Mining Rig Rentals, the miner or ASIC firmware, and the pool must all match.


ASIC miners are the normal choice for Zcash

Older Zcash guides often recommended CPU or GPU miners. That information is no longer good practical guidance for modern Zcash mining.

Current Zcash mining is dominated by ASIC miners. Zcash’s own mining guide says an ASIC is required due to current network difficulty.

For Mining Rig Rentals, this means most Zcash-capable rigs will be ASIC-based. The ASIC’s built-in firmware usually handles the actual mining software. In most cases, you do not need to install a separate GPU miner.

A Zcash ASIC should work with Mining Rig Rentals if it can:

  • mine Zcash-compatible Equihash,
  • connect to a custom pool address,
  • use the worker name or username required by Mining Rig Rentals,
  • use the password field required by Mining Rig Rentals or the renter’s pool,
  • submit accepted shares,
  • reconnect cleanly,
  • maintain stable hashrate during the rental,
  • expose useful miner logs or status information.

If the ASIC firmware is locked to a specific manufacturer pool or does not allow custom pool settings, it may not be usable with Mining Rig Rentals.


GPU and CPU miners

Some old Zcash mining software was written for CPUs or GPUs. These miners may still exist, but they should not be presented as the normal way to mine Zcash today.

CPU and GPU miners may be unsuitable because:

  • current Zcash network difficulty is too high for practical CPU/GPU mining,
  • old miners may no longer be maintained,
  • driver support may be broken,
  • stratum support may be outdated,
  • hashrate may be far below modern ASIC performance,
  • old download links may be unsafe or dead,
  • the miner may not reconnect or report shares correctly.

Mining Rig Rentals should not maintain an old static list of Zcash CPU/GPU miner downloads. That list will become inaccurate and may encourage users to run abandoned software.

If a user operates unusual hardware or legacy software, they must test it through Mining Rig Rentals before listing it.


What makes a Zcash miner compatible?

A miner or ASIC is generally compatible with Mining Rig Rentals if it can reliably mine through the Mining Rig Rentals connection and submit accepted shares to a Zcash pool.

The miner should be able to:

  • connect to a custom stratum pool URL,
  • mine the correct Zcash Equihash algorithm,
  • use custom worker and password fields,
  • receive jobs from the pool,
  • submit shares correctly,
  • handle pool difficulty changes,
  • reconnect after interruptions,
  • report accepted, rejected, and stale shares,
  • remain stable for the full rental period.

The miner name alone does not guarantee compatibility.

A direct connection to a pool is useful for testing, but the rig must also be tested through Mining Rig Rentals before being listed for rent.


Renting hashrate to mine Zcash

To mine Zcash as a renter:

  1. Choose the Equihash/zcash algorithm category.
  2. Select a rig with suitable hashrate, price, location, and rental history.
  3. Configure your Zcash pool information.
  4. Use the pool’s required wallet, worker, and password format.
  5. Start the rental.
  6. Confirm that your pool shows accepted shares.

Do not rent an Equihash 144,5 or other Equihash-variant rig for Zcash unless you are intentionally mining a coin that uses that variant.

For Zcash, use the Zcash-compatible Equihash category.


Pool configuration

Before renting or listing a Zcash rig, confirm the pool’s required connection format.

Check:

  • pool URL,
  • pool port,
  • wallet or username format,
  • worker name format,
  • password field requirements,
  • TLS or non-TLS port,
  • fixed difficulty options,
  • regional pool servers.

Some pools allow a plain wallet address. Others may require wallet.worker, a username, a password parameter, or a specific difficulty setting.

Incorrect pool format can cause the miner to connect but fail to submit accepted shares.


Difficulty settings

Zcash pools may use variable difficulty or allow fixed difficulty.

If share difficulty is too low, the miner may submit excessive shares. If share difficulty is too high, shares may arrive less often and short-term hashrate reporting may look unstable.

For renters, use the pool’s recommended rental or ASIC difficulty settings if available.

For rig owners, set your rig’s Suggested Difficulty based on the stable share difficulty observed when the ASIC is mining normally through Mining Rig Rentals.

Do not use Zcash network difficulty as your Suggested Difficulty. Network difficulty and share difficulty are different.


Listing a Zcash rig as a rig owner

Before listing a Zcash rig, test it through Mining Rig Rentals.

Confirm that:

  • the rig is listed under Equihash/zcash,
  • the ASIC or miner supports Zcash-compatible Equihash,
  • the firmware allows custom pool settings,
  • the miner connects through Mining Rig Rentals,
  • accepted shares increase on a known working Zcash pool,
  • rejected shares remain low,
  • stale shares remain low,
  • the rig maintains stable hashrate,
  • the advertised hashrate reflects real sustained performance,
  • the rig reconnects properly after pool or network changes.

Do not list a Zcash rig based only on the ASIC dashboard showing local hashrate. Verify accepted shares through Mining Rig Rentals and the pool.


Common Zcash setup problems

Wrong Equihash variant

This is the most important issue.

Zcash-compatible Equihash is not the same as Equihash 144,5, 192,7, 210,9, or other variants.

If the wrong variant is selected, the miner may show activity but the pool may reject the work.


Miner connects but no shares are accepted

Possible causes include:

  • wrong algorithm category,
  • wrong pool port,
  • wrong wallet or username format,
  • incorrect password field,
  • ASIC firmware incompatibility,
  • pool difficulty too high,
  • pool-side issue,
  • using a non-Zcash Equihash variant.

Connection status alone does not prove the rental is working. Accepted shares must increase.


High rejected shares

Possible causes include:

  • wrong Equihash variant,
  • unstable ASIC hardware,
  • firmware bug,
  • incorrect pool settings,
  • difficulty mismatch,
  • overheating,
  • bad hashboard,
  • pool rejecting the submitted work.

Check ASIC logs, worker data, and pool-side reject messages.


Pool-side hashrate is lower than expected

Possible causes include:

  • pool reporting delay,
  • high share difficulty,
  • short rental duration,
  • stale or rejected shares,
  • unstable ASIC performance,
  • advertised hashrate set too high,
  • pool-side calculation differences.

Evaluate hashrate over a reasonable period, not only the first few minutes of a rental.


Do not rely on old Zcash miner lists

Older articles may mention miners such as Genoil ZECMiner, nheqminer, early EWBF versions, or other CPU/GPU miners.

Those references are legacy and should not be treated as current Mining Rig Rentals setup guidance.

Instead of relying on a miner name, confirm that the miner or ASIC can:

  • mine Zcash-compatible Equihash,
  • connect through Mining Rig Rentals,
  • submit accepted shares,
  • remain stable,
  • deliver the advertised hashrate.

Testing is the compatibility check that matters.


When to contact support

Contact Mining Rig Rentals support if your Zcash miner works directly with a pool but does not work correctly through Mining Rig Rentals.

Include:

  • rental ID or rig ID,
  • algorithm category selected,
  • ASIC model or miner software,
  • firmware version if available,
  • pool URL and port,
  • wallet or worker format used,
  • password field used, if relevant,
  • screenshots of the pool dashboard,
  • screenshots of the Workers tab,
  • miner logs showing accepted, rejected, or stale shares,
  • approximate time the issue occurred,
  • whether the issue happens on more than one pool.

Clear details help determine whether the issue is renter-side, rig-side, pool-side, firmware-side, or platform-side.


Summary

For Zcash, use Equihash/zcash on Mining Rig Rentals.

Do not use old CPU/GPU miner lists as current guidance. Do not use Equihash 144,5 or another Equihash variant for Zcash unless you are intentionally mining a different coin that requires that variant.

Modern Zcash mining is normally ASIC-based. Before renting or listing a Zcash rig, confirm the correct algorithm category, configure the pool correctly, and verify that accepted shares are increasing.
