Some older mining software, ASIC firmware, and proxy setups use Ethereum-style mining protocols that were originally developed for Ethash, Dagger-Hashimoto, or similar algorithms.

Mining Rig Rentals may be able to route some of these connections when they use compatible stratum behavior, but support is limited. These setups are more likely to require testing and may not work with every miner, ASIC, firmware version, proxy, or pool.

This article is intended for advanced users who are trying to connect Ethash-style miners or proxies through Mining Rig Rentals.

Important: Ethereum itself is no longer mineable

Ethereum no longer uses proof-of-work mining.

Since Ethereum moved to proof-of-stake, Ethereum miners and Ethereum ASICs cannot mine Ethereum mainnet. Hardware or software that was originally built for Ethereum may still be usable on other compatible proof-of-work coins or Ethash-family algorithms, but that does not mean it is mining Ethereum.

When this article refers to Ethereum-style mining, it means legacy Ethash or Dagger-Hashimoto-style mining behavior, not mining Ethereum mainnet.

Limited support for Ethereum-style stratum

Mining Rig Rentals may support some Ethereum-style stratum connections, depending on the miner, proxy, firmware, and pool being used.

However, compatibility is not guaranteed.

Ethereum-style mining has used several different protocol behaviors over time. Some miners use eth_ style JSON methods. Others use stratum-like mining.subscribe, mining.notify, or mining.submit behavior with Ethash-specific modifications. Some ASICs and proxies implement these behaviors differently or incompletely.

Because of this, two miners that claim to support the same algorithm may not behave the same way when routed through Mining Rig Rentals.

ASIC compatibility

Some Ethash-capable ASICs may work through Mining Rig Rentals if their firmware allows proper custom pool configuration and uses a compatible stratum method.

An ASIC is more likely to work if it allows you to configure:

• pool URL,
• pool port,
• worker name or username,
• password field,
• backup pools,
• algorithm or coin mode where applicable.

An ASIC may not work if:

• the firmware is locked to a manufacturer pool,
• the pool settings are restricted,
• the ASIC uses a non-standard stratum implementation,
• the firmware does not reconnect cleanly,
• it cannot submit accepted shares through Mining Rig Rentals,
• it requires a pool feature that Mining Rig Rentals does not proxy or translate.

Do not assume an Ethash ASIC is compatible simply because it can mine directly to a pool.

You must test it through Mining Rig Rentals before listing it.

Proxy-based setups

Some users may try to connect Ethash-style hardware through a stratum proxy or translation proxy.

A proxy may help when the miner and pool use different Ethereum-style protocol variants, but it can also introduce problems.

Common proxy-related problems include:

• rejected shares,
• stale shares,
• duplicate shares,
• failed authorization,
• broken reconnect behavior,
• incorrect worker names,
• incorrect extranonce handling,
• pool switching failures,
• inaccurate hashrate reporting,
• hidden worker instability,
• incompatibility with renter pools.

Mining Rig Rentals does not guarantee that third-party proxies will work. If you choose to use a proxy, you are responsible for testing and maintaining it.

A proxy setup should not be listed for rent unless it can mine through Mining Rig Rentals to a known working pool and submit accepted shares consistently.

GPU miner compatibility

Some older GPU miners were designed for Ethereum or Dagger-Hashimoto mining and may no longer be maintained.

Avoid relying on old setup guides for miners such as legacy ethminer builds, qtminer, Claymore, or old getwork-to-stratum proxy examples. These tools may be outdated, abandoned, incompatible with modern drivers, or unsuitable for current rental use.

A GPU miner should only be used if it:

• supports the selected algorithm,
• accepts a custom pool address,
• accepts the required worker and password fields,
• submits accepted shares through Mining Rig Rentals,
• reconnects correctly,
• remains stable over time,
• produces low rejected and stale shares.

If the miner only works with a direct pool connection but not through Mining Rig Rentals, do not list it until the issue is resolved.

Do not use old getwork-only instructions

Old Ethereum mining guides often mention getwork, local HTTP proxies, or direct ethminer -F style configurations.

These instructions are legacy and should not be treated as current Mining Rig Rentals setup guidance.

Modern listings should be tested using the actual connection details shown in your Mining Rig Rentals rig setup page. If a proxy is required, it must be tested as part of your full rig configuration before the rig is made available for rent.

How to test compatibility

Before listing an Ethash-style rig or proxy setup, test it carefully.

Recommended test process:

1. Configure the miner, ASIC, or proxy using the Mining Rig Rentals connection details.
2. Select the correct algorithm for the rig listing.
3. Connect through Mining Rig Rentals.
4. Mine to a known working pool for that algorithm.
5. Let the rig run long enough for difficulty and hashrate reporting to stabilize.
6. Confirm accepted shares are increasing.
7. Confirm rejected and stale shares are low.
8. Confirm the miner reconnects correctly.
9. Check the Workers tab for hashrate, share difficulty, and worker status.
10. Compare miner-side, pool-side, and Mining Rig Rentals reporting.

Connection status alone is not enough. The rig must submit accepted shares.

Signs the setup is not compatible

Your miner, ASIC, or proxy may not be compatible if:

• it connects but submits no accepted shares,
• all or most shares are rejected,
• shares are repeatedly stale,
• the miner disconnects and reconnects repeatedly,
• the renter’s pool does not receive work,
• worker names are not passed correctly,
• the proxy crashes or hangs,
• hashrate reporting is inconsistent or unusable,
• the setup only works with one specific pool,
• pool switching does not work during rentals.

If these problems occur, test without the proxy where possible, test with another known-good pool, review miner logs, and verify the algorithm and pool format.

Renter pool compatibility

Even if your setup works with one pool, it may not work with every renter’s pool.

Some pools expect specific stratum behavior, password options, coin modes, TLS settings, or worker formats. Ethereum-style protocol differences make this more likely than with normal stratum mining.

Rig owners should not advertise a setup as broadly compatible unless it has been tested through Mining Rig Rentals and behaves reliably under normal rental conditions.

Resold or third-party hashrate

If the hashrate comes from another marketplace, cloud mining service, or external provider, compatibility is even less predictable.

Third-party hashrate may fail if the provider does not allow:

• custom pool configuration,
• stable reconnect behavior,
• correct algorithm selection,
• correct worker naming,
• compatible Ethereum-style stratum behavior,
• enough visibility to troubleshoot rejected or stale shares.

If you do not control the actual miner, firmware, proxy, or logs, support options may be limited.

Summary

Ethereum-style mining support is legacy and compatibility varies by miner, ASIC firmware, proxy, algorithm, and pool.

Before listing one of these rigs, confirm that it can:

• connect through Mining Rig Rentals,
• mine the selected algorithm,
• submit accepted shares,
• reconnect correctly,
• maintain stable hashrate,
• work with the pool configuration renters are likely to use.

Do not rely on old Ethereum, qtminer, Claymore, ethminer, or getwork proxy guides. Test the actual rig through Mining Rig Rentals before making it available for rent.
