1. Understanding PRL Pearl Coin

1.1 What is PRL

PRL is the network token of the Pearl Network.

The Pearl Network uses PoUW, Proof of Useful Work, a useful proof-of-work mechanism. PRL employs the PearlHash mining algorithm, supporting GPU devices to participate in network computing.

Currently, PRL mining mainly uses NVIDIA GPUs, with common devices including NVIDIA RTX 50, 40, and 30 series graphics cards. Some AMD and Intel Arc graphics cards can also participate in mining through compatible kernels, but different models have varying hashrate, power consumption, and software support. The current KuPool tutorial recommends GPUs have at least 6GB of VRAM.

Unlike coins such as LTC and ZEC, which are dominated by ASIC professional miners, PRL is mainly mined using GPU miners or GPU servers.

 

1.2 What is PearlHash

PearlHash is the mining algorithm used by PRL.

The mining software calls the GPU to perform PearlHash computation tasks and submits qualifying results to KuPool.

KuPool calculates mining rewards based on the effective work submitted by miners and the current settlement rules. The current KuPool PRL tutorial shows that PRL uses the PPS (Pay Per Share) reward distribution method; specific fees and payment rules are subject to the KuPool account page and latest announcements.

 

1.3 Differences Between PRL Mining and ASIC Mining

Coins such as LTC, BTC, and ZEC currently mainly use ASIC professional miners designed for fixed algorithms.

PRL mainly uses GPU devices.

The main differences between the two types of devices include:

GPU Miners

• Require installation of operating system and GPU drivers;
• Require downloading mining kernels;
• Require configuration of startup commands;
• Can adjust parameters for individual GPUs;
• Performance varies significantly among different GPU models;
• Can switch to other compatible GPU tasks;
• Software, drivers, and parameters greatly affect stability.

ASIC Miners

• Usually configured via web backend to input pool parameters;
• Devices support only specific algorithms;
• Configuration is relatively fixed;
• Maintenance focuses on hash boards, chip temperature, and power supply;
• Devices have relatively single-purpose use.

Therefore, PRL tutorials need to focus on GPU compatibility, drivers, mining software, and GPU parameters, and cannot directly apply ASIC miner configuration methods.

2. Preparations Before Mining

2.1 GPU Requirements

PRL currently mainly uses GPU devices for mining.

Common devices listed in the current KuPool tutorial include:

• NVIDIA RTX 50 series;
• NVIDIA RTX 40 series;
• NVIDIA RTX 30 series;
• Other NVIDIA GPUs supported by PearlHash kernels;
• Some AMD RX 50 series and newer models;
• Some Intel Arc series GPUs.

Some AMD and Intel Arc models can participate in PRL mining, but actual earnings may differ from NVIDIA devices.

It is recommended that GPUs have at least 6GB of VRAM.

When selecting devices, confirm:

• GPU model is supported by the current mining kernel;
• VRAM capacity meets requirements;
• Driver version is compatible with the kernel;
• GPU has no VRAM errors;
• GPU does not frequently drop drivers;
• GPU cooling is normal;
• Power supply can meet total power consumption;
• Motherboard can recognize all GPUs.

The following devices are not recommended for PRL mining:

• GPUs with insufficient VRAM;
• GPUs that have VRAM errors;
• GPUs that frequently drop cards or crash;
• Devices with long-term outdated drivers;
• Multi-GPU miners with insufficient power margin;
• Models not explicitly supported by the current mining kernel.

2.2 Other Hardware Requirements

Besides GPUs, a complete GPU miner requires:

• No circuit exceeds safe load.

Do not use ordinary household power strips with insufficient rated power to connect multi-GPU miners.

When calculating electricity costs, prioritize using power meter or smart PDU readings of total wall power consumption rather than only calculating GPU power consumption shown by mining software.

2.4 Network Requirements

Miners should use a stable wired network.

Before starting, confirm:

• Router can access the internet normally;
• Network cables are connected properly;
• DHCP function is working;
• Miner can obtain an IP address;
• DNS resolution is normal;
• Firewall does not block mining software;
• Network does not frequently drop packets;
• Latency from miner to KuPool access node is stable;
• System time and time zone are correct.

For large mining farms, it is recommended to configure:

• Primary and backup networks;
• Fixed IP or DHCP address reservation;
• Dedicated miner network;
• Switch port monitoring;
• Network outage alerts;
• Proxy service operation status alerts.

2.5 Cooling Requirements

GPU miners continuously generate heat during operation.

Ensure that:

• GPU intake areas are unobstructed;
• Hot air is expelled promptly;
• Hot air does not re-enter the miner;
• Reasonable spacing is maintained between GPUs;
• Ambient temperature is within device limits;
• Fans are operating normally;
• Dust is cleaned regularly;
• GPU core and VRAM temperatures are within normal ranges.

If using GPU servers, also check:

• Server airflow channels;
• Cabinet airflow direction;
• Server fans;
• Hot and cold aisles in data center;
• GPU throttling status;
• Data center air conditioning and exhaust capacity.

2.6 Operating System

PRL mining can use:

• Windows 10;
• Windows 11;
• Linux;
• Professional mining OS like HiveOS;
• Other GPU management systems supporting PearlHash kernels.

KuPool currently recommends:

• Windows mainly for remote operation and standard GPU miners;
• Linux mainly for GPU servers and professional computing devices;
• Use professional mining management systems for multiple miners or centralized management.

2.7 GPU Driver Check

Before mining, confirm:

• GPU drivers are correctly installed;
• System recognizes all GPUs;
• No GPU errors in Device Manager;
• Mining software supports current driver version;
• GPU does not frequently drop drivers;
• System time and time zone are normal;
• GPU is not heavily occupied by other programs.

On Windows, open "Device Manager" and check under "Display adapters" for all GPUs.

If a yellow exclamation mark appears next to a GPU, first troubleshoot:

• Drivers;
• PCIe riser cards;
• GPU power supply;
• Motherboard BIOS;
• System resources;
• GPU hardware status.

2.8 Windows System Settings

It is recommended to complete the following settings:

• Disable system auto-sleep;
• Disable hard drive auto-sleep;
• Prevent Windows from auto-restarting for updates during mining;
• Set sufficient virtual memory;
• Add mining software directory to security software exclusions;
• Close unnecessary programs that may occupy GPU;
• Set system to auto-login;
• Set mining program to auto-run on startup;
• Ensure system time auto-sync.

Security software may identify some mining programs as risky software.

This does not mean all mining software is safe. Only download from official developer pages or trusted KuPool links. Do not run programs from unknown sources.

3. KuPool Registration, Login, and Sub-accounts

Refer to the following tutorials for detailed steps:

KuPool Registration and Login

How to Set Up Sub-accounts

When creating a PRL sub-account, it is recommended to name it based on mining farm, customer, data center, or device type, for example:

• prl-hk01;
• prl-gpu-a;
• prl-4090;
• customer01-prl;
• server-room02.

Miner identification usually consists of sub-account and worker name.

Example:

prl-hk01.GPU-001

Where:

• prl-hk01 is the KuPool sub-account;
• GPU-001 is the worker name;
• The dot separates the sub-account and worker name.

Different mining software may have different ways to fill in account and worker names.

Some software merges the two as:

sub-account.worker-name

Some software separates sub-account and worker name.

Fill in according to KuPool’s provided access parameters and mining software instructions during actual configuration.

4. Preparing PRL Payment Address

After configuring the PRL miner, you also need to bind a valid PRL payment address on KuPool.

Once the address is successfully verified and activated, KuPool will send PRL earnings that meet the payout threshold to this address according to current settlement and payment rules.

1. Using the Official PRL Wallet

Visit the official PRL wallet page and register.

After logging in:

1. Click "My Wallet";
2. Find "Receive Address";
3. Click the copy button below;
4. Obtain the PRL wallet address;
5. Verify the address is complete;

2. Backing Up Wallet Recovery Information

After creating the official wallet, immediately back up wallet recovery information.

On the wallet page, find:

Recovery Phrase

Click:

Export Recovery Phrase

You can choose to:

• Copy Key, copy the private key;
• Copy Phrase, copy the mnemonic phrase;
• Or back up both private key and mnemonic phrase.

The private key and mnemonic phrase represent control over wallet assets.

Be sure to:

• Store offline;
• Prepare at least two backups;
• Verify the order of mnemonic words;
• Do not send via chat software;
• Do not send via email;
• Do not store in online documents;

Note that KuPool only requires the public PRL payment address and will never ask users for private keys or mnemonic phrases.

3. Using Wallets or Deposit Addresses Supporting PRL

Besides the official wallet, you can also use wallet services or asset platform addresses explicitly supporting PRL deposits.

After logging into the respective service:

1. Go to asset or deposit page;
2. Search for PRL;
3. Select Pearl Network;
4. Obtain PRL deposit address;
5. Verify address and network;
6. Check if deposit function is normal.

Before using such addresses, confirm:

• Platform currently supports PRL deposits;
• Deposit network is Pearl Network;
• Deposit address is complete;
• Whether there is a minimum deposit amount;
• Whether the address is permanently valid;
• Whether the platform has suspended PRL deposits;
• Whether your country or region allows use of the related services.

Regulatory requirements vary by country and region. Users should independently confirm local policies and assess risks related to accounts, deposits, and asset custody.

4. Wallet Address Usage Recommendations

Before using a new address, it is recommended to:

• Verify the first 6 characters of the address;
• Verify the last 6 characters of the address;
• Confirm the network is Pearl Network;
• Ensure the address has no extra spaces;
• Confirm it is not an address of another coin;

5.1 Address Modification Freeze Period

Please note that after each new addition or modification of an address, payments will be suspended for 48 hours.

During the freeze period:

• Mining rewards continue to be calculated normally;
• Rewards enter the KuPool account balance;
• No payments are sent to the wallet temporarily;
• Payments resume on the first eligible settlement day after the freeze ends.

Specific freeze status and duration are subject to actual display on KuPool pages.

5.2 Security Reminders When Binding Addresses

When binding addresses, please note:

• KuPool only requires the public payment address;
• Do not enter private keys or mnemonic phrases;

6. Downloading PRL Mining Software

6.1 Supported Mining Software

KuPool’s current PRL tutorial recommends the following software:

SRBMiner-Multi

Compatible devices include:

• NVIDIA GPU series;
• Some AMD RX 50 series and newer models;
• Intel Arc series GPUs.

tw-pearl-miner

Mainly compatible with:

• NVIDIA GPUs.

Specific compatible models and latest versions should be based on the software’s official release page.

6.2 How to Choose a Kernel

When choosing mining software, consider:

• GPU brand;
• GPU model;
• Operating system;
• Driver version;
• Kernel hashrate;
• Power consumption performance;
• Stability;

The same GPU may have different hashrate, power consumption, and stability on different kernels.

It is recommended to first test with KuPool’s currently recommended version and avoid using unverified old or modified versions directly.

6.3 Software Update Notes

PearlHash kernels may continue to be optimized.

For example, later versions of SRBMiner-Multi have optimized PearlHash performance for NVIDIA RTX 20, 30, 40, 50 series and some AMD devices. Different versions may also provide additional parameters for specific GPUs.

Before upgrading kernels, it is recommended to:

1. Record the original version;
2. Save the original startup commands;
3. Record original hashrate and power consumption;
4. First upgrade a small number of test machines;
5. Compare effective hashrate;
6. Check rejection rate;
7. Check stability;
8. Keep old versions for rollback.

7. Obtaining KuPool PRL Proxy

KuPool’s current PRL tutorial uses a proxy access method.

If you need to use a PRL proxy, please contact your customer manager to obtain:

• Proxy program;
• Proxy deployment tutorial;
• KuPool access parameters;
• Account filling format;
• Miner connection address;
• Port;
• Node information;
• Backup access methods.

KuPool’s official tutorial currently requires users to contact the KuPool key account manager to get the PRL proxy.

Do not use proxy programs from unknown sources or unknown proxy addresses provided by others.

Using unofficial proxies may cause:

• Hashrate being redirected;
• Earnings going to others’ accounts;
• Proxy program being remotely controlled;
• Internal network device information leakage;
• High rejected shares;
• Proxy disconnections;
• Inability to receive KuPool technical support.

8. Deploying KuPool PRL Proxy

8.1 Proxy Device Requirements

Proxy devices usually need to meet:

• Network connectivity with GPU miners;
• Stable network connection;
• Ability to run continuously;
• Correct system time;
• Firewall allows specified ports;
• No conflicts with other service ports;
• Sufficient CPU and memory;
• Access to KuPool nodes.

Actual hardware, system, and network requirements are subject to KuPool’s PRL proxy deployment tutorial.

 

9. Windows Miner Configuration

9.1 Configuration Structure

PRL startup commands usually include:

• Mining program name;
• PearlHash algorithm;
• KuPool proxy address;
• Proxy port;
• KuPool sub-account;
• Worker name;
• Log parameters;
• Auto-reconnect parameters;
• Other GPU or kernel parameters.

Parameter names differ slightly between kernels.

For official configuration, use the proxy parameters and kernel instructions provided by KuPool.

 

11. Checking Miner Operating Status

11.1 Local Checks

After starting the miner, check:

• Number of GPUs recognized by the system;
• Number of GPUs recognized by the kernel;
• Hashrate per GPU;
• Total hashrate of the machine;
• GPU core temperature;
• GPU VRAM temperature;
• Fan speed;
• Power consumption per GPU;
• Proxy connection status;
• Accepted Shares;
• Rejected Shares;
• Whether the kernel restarts frequently.

If 8 GPUs are installed, the mining kernel should also recognize 8 GPUs.

11.2 KuPool Backend Checks

Log into KuPool:

1. Go to the mining page;
2. Switch to the PRL sub-account;
3. Open miner management;
4. Check if the miner is online;
5. View real-time hashrate;
6. View average hashrate;
7. View rejection rate;
8. View PRL earnings;
9. View pending payout balance;
10. View payment records.

After starting the miner, valid shares must be submitted first before KuPool backend gradually forms effective hashrate statistics.

11.3 Local Hashrate vs. KuPool Hashrate

Local hashrate is the instantaneous value calculated by mining software based on GPU status.

KuPool hashrate is estimated based on valid shares received over a period.

Therefore, situations may occur where:

• Local hashrate is present, but KuPool does not yet show it;
• KuPool real-time hashrate is higher than local hashrate;
• KuPool real-time hashrate is lower than local hashrate;
• Short-term fluctuations are large;
• Long-term average hashrate is relatively stable.

When judging if a miner is operating normally, prioritize observing longer-term average hashrate, valid shares, and rejection rate.
