How to Mine XHD in 2026?
XHD, also called XRPHD, is a hard drive mining cryptocurrency built on Conditioned Proof of Capacity (CPOC). It uses plotted hard drive space instead of a graphics card or an ASIC rig. The network assigns rewards based on the amount of storage used for mining.
In this guide, you will learn how to:
How XHD mining works?
In order to start XHD mining, a miner must prepare hard drive space and write plot files to the disk. The mining software then uses that stored data whenever a new block appears and checks whether it can produce a valid deadline.
XHD uses a different mining model than standard Proof of Work. A PoW miner keeps solving new calculations, while an XHD miner relies on data written to the drive in advance. More plotted space gives the miner a better chance of producing the best deadline and receiving the block reward.
Plot files store the data used in mining. That data is organized into nonces, and each nonce is divided into smaller parts called scoops. For every new block, the software reads the relevant scoop, calculates a deadline, and submits it to the network if it meets the required value.

What do you need to start mining XHD?
You must set up your XHD wallet before you plot any drive. Each plot file is created for a specific wallet address, and all mining rewards will be allocated to that address.
To start mining XHD, you need:
- A computer with stable network access
- One or more HDDs for plot files
- The XHD full node wallet
- Mining software
- Enough drive space for the capacity you plan to plot
High-end graphics hardware is not required. CPU performance mainly affects how long it takes to create plot files. After plotting is complete, mining relies on disk access and consistent access to the plotted files.
Use a separate system drive for the operating system to keep the setup more organized. Reserve mining HDDs for plot files only. This will make future drive additions or replacements easier.
What is the best HDD for XHD mining?
You should choose an HDD based on these factors:
- Price per usable terabyte
- Warranty length
- Drive type
Plotted capacity will determine your mining output. A 16TB drive with only 10TB plotted will mine as 10TB of capacity. Unused space will not count until you plot it.
Larger drives will reduce the number of bays, SATA ports, and cables needed for the same plotted capacity. A single reliable HDD will be enough for a first XHD build. It will let you test wallet setup, plotting, mining software, and reward tracking before you expand capacity. You will be able to add more drives later and assign separate nonce ranges to each one.
Here’s the list of drives that perform well for XHD mining:
We cannot recommend or advocate for any particular models, though. Look up these drives and use them as a starting point for your own research.
How do you set up the XHD wallet?
Install the XHD full node wallet and allow it to sync with the current chain. Generate a wallet address, then back up the wallet file and recovery information.
You must confirm the wallet address and account ID before you start plotting. Some plotting tools will require the numeric account ID. Plotting will take hours, and in some cases days. An error at this stage will waste that work.
Keep a local record with:
- The wallet address
- The numeric account ID, if the plotting tool requires it
- The list of drives assigned to that wallet
You should store wallet backups offline. A failed drive or a deleted file will otherwise cut off access to future rewards.
How do you create plot files?
Plotting will write mining data to the HDD. The process can take hours or several days. Drive size, CPU speed, write throughput, and the plotting tool will determine how exactly long it takes. Larger drives will take longer because the software will need to fill more space with valid data.
Each plotting job will require:
- The account ID
- The starting nonce
- The nonce count
- The destination folder
The account ID will link the plot file to your wallet. The starting nonce and nonce count will define the exact nonce range stored on that drive.
You must not reuse nonce ranges across different drives. Two HDDs with the same range will not add effective capacity. The miner will read the same data twice. Keep a local record for each drive with its size, starting nonce, and nonce count.
Optimized plot files will reduce unnecessary disk seeking during mining. The miner will read the plotted data more efficiently, especially on systems where several drives share one controller or USB hub.
How do you configure the mining software?
Once plotting is complete, you must add each plot folder to the mining software and enter the wallet address used during plotting. Then, you will need to choose pool mode or solo mode. The software must detect the full plotted capacity before it begins to submit deadlines.
The first startup will confirm whether the configuration is correct. The miner should display the total plotted capacity, the current block height, and the deadlines it finds. The reported capacity should match the amount of plotted space assigned to the miner.
A zero-capacity reading will usually point to an incorrect plot folder path, a mismatched account ID, missing file permissions, or the wrong drive letter. You should verify each of these before you assume the plot files are damaged.
Keep the miner active long enough to confirm that every assigned drive is being read correctly. A drive that remains inactive usually indicates a cable issue or an incorrect folder setting.
Pool Mining vs Solo Mining
Pool Mining
Pool mining will combine your capacity with the capacity from other miners. Your miner will submit work to the pool, and the pool will distribute payouts based on your contributed capacity and accepted work. Payouts will usually arrive in smaller, more regular amounts compared to solo mining.
Solo Mining
Solo mining will use only your own wallet and plotted capacity. If your miner finds a block, you will receive the full block reward. Smaller setups can wait much longer between block wins because they will compete against the full network on their own.
Pool mining is the more practical starting point for most XHD miners. Your choice of pool will affect fees, payouts, and connection settings.
Review the following before you connect your miner:
- Fee percentage
- Payout rules
- Minimum payout
- Connection settings
- Reported worker capacity
How do block rewards work?
XHD uses capacity-based rewards. XHD will pay a fixed 8,000 XHD per T until total network capacity reaches 1000 PB. After that threshold, the rate will change. Each new rate will be based on the average capacity recorded over the previous 2016-block window.
The effective reward rate will also depend on how long capacity remains committed.
| Time committed | Effective rate |
|---|---|
| Over 9 months | 100% |
| Over 6 months | 60% |
| Over 3 months | 30% |
| Under 3 months | 10% |
Reward estimates will need to use effective capacity rather than raw disk size.
How do you estimate HDD mining profitability?
Effective capacity will serve as the base for any profitability estimate. Raw drive size can overstate expected output, so the calculation should reflect only the capacity that counts toward rewards.
The calculation should account for:
- Effective capacity
- Total network capacity
- Current reward rate
- Pool fee
- Electricity cost
- Hardware cost
- XHD market price
- Current market availability
Here’s how you should calculate profitability:
- Measure your share of total network capacity
- Estimate how much XHD that share can generate over the period you want to track
- Deduct pool fees and electricity costs
- Include the hardware cost if the drives were purchased for mining
- Compare the result with the current XHD market price
Trading access will affect the final result as well. A break-even estimate will remain incomplete until you confirm where XHD is trading and whether you can sell the amount you plan to mine.
Common XHD mining problems and how to solve them
1. Rewards go to the wrong wallet.
If mined XHD does not appear in the expected wallet, check the wallet address and account ID used during plotting. Plot files are tied to that data. If the address or account ID does not match, the affected drive will need to be replotted. A miner restart will not correct that mismatch.
2. Reported capacity is lower than expected.
If the miner shows less capacity than you plotted, review every plot folder path, drive letter, and nonce range. Remove any duplicate ranges and add any missing plot folders. The capacity shown by the miner should match the amount of plotted space assigned to it.
3. Deadlines arrive too slowly or stop appearing.
If deadlines become slow or inconsistent, check drive response, controller load, USB connectivity, and drive temperature. Move overloaded drives off shared hubs, confirm stable connections, and use optimized plot files where possible. Systems with several HDDs on one shared connection may lose read performance during mining rounds.
4. The miner shows zero capacity.
A zero-capacity reading usually points to an incorrect plot folder path, wrong account data, missing file permissions, or a drive that is not mounted correctly. Check it first. After that, restart the miner and confirm that every assigned drive is visible under the correct path or drive letter.
5. The wallet is out of sync.
A full node wallet must stay on the current chain state. If the wallet falls behind, let it complete sync before you change plot files or mining settings. Then confirm the current block height in the wallet and in the miner.
