QLC Miner for Windows is a free, open-source mining program written in Go, aimed at developers who want a simple miner to test with. It is not built as a polished everyday tool for people chasing mining income, and its scope is deliberately narrow.
Before you install it, note the project status: there have been no code updates since February 2020, so the software is effectively unmaintained. The latest release is v1.3.0. That makes it a poor choice for anything beyond learning how a miner is structured or running short tests on your own machine. The sections below cover installation, safety checks and how it compares with other miners, including several listed programs that have also stopped development.
What Is a Developer Test Miner?
A mining program does two jobs: it performs the computing work a network asks for, and it reports progress so the operator can see what is happening. Production miners add tuning options, dashboards and support for specific algorithms. A developer test miner strips that down. Its value is in showing the moving parts clearly, so you can see how a connection is made, how work is handled and where failures appear.
Two terms come up often. Hashrate measures how much work a device completes per second, and it is the basic unit for comparing hardware. A mining pool combines the work of many participants and shares rewards by contribution. Once you understand these, a small tool like this makes more sense, because you can follow each step without a crowded interface getting in the way.
Testing in a controlled environment matters. Run the program on a machine you control, with no real funds tied to the test setup, and watch what happens. That habit makes it easier to catch configuration mistakes before they cost anything.
Who Is QLC Miner For?
The program fits three kinds of readers. The first is a developer working on QLC-related software who needs a simple miner to exercise a build or confirm that a setup behaves as expected. The second is a student or self-learner who wants to read a compact mining codebase written in Go. The third is someone comparing mining software at a technical level who wants to see what a minimal implementation looks like.
It is a weaker fit for people hoping to earn from mining. The project is aimed at developer testing, and it has not been updated since February 2020. Miners looking for ongoing updates and broader hardware support should compare the alternatives listed below and check each project's status before choosing.
If you fall into the first two groups, a typical session might look like this: build from the repository, read the main files, run the program against a test setup, and note what each output line means. That approach gets more value from a small tool than simply starting a miner and hoping for results.
Key Concepts: Developer Fees and Reading the Source
Many mining programs include a developer fee, which is a small share of the work routed to the program's author. Before you run any miner, look for how fees are handled in its source code and documentation. Transparency here is a basic check of whether the tool does what it claims.
Reading the source is one of the most useful things you can do with an open-source miner. Start with the entry point, then follow how the program reads its settings, connects to a server and handles results. Pay attention to anything that sends data outside the machine. Even a simple tool deserves that scrutiny, because behavior cannot be judged from the name alone.
Source reading also helps with version differences. Compare the code of the release you downloaded with the repository at the time you run it. If the code has not changed in years, the behavior you see today is the behavior that was written then, which is useful to know when diagnosing problems.

How to install QLC Miner on Windows
- 1
Get the files
Download the program only from the official website or the project's GitHub Releases page, which is linked from the source repository at github.com/qlcchain/qlc-miner. Avoid mirrors and file-sharing links, since copies of mining software are often altered.
- 2
Verify the file
Compare the SHA-256 checksum of the downloaded file with the value published alongside the release. If a signature is provided, check it as well. Do not run a file whose hash does not match the published value.
- 3
Install or unpack
Run the Windows installer, or extract the Windows build to a folder of your choice. Pick a dedicated folder so you can remove the program cleanly later, and keep test files out of it.
-
Build from source if you prefer
To build from the repository, clone it and run make clean build in a terminal with the required tooling installed. A Go toolchain and make are needed only for this build step, not for running the finished program.
How to use QLC Miner
A short session with QLC Miner is mostly about understanding the output, not chasing results. Keep the test on a machine you control and treat the first run as a learning exercise.
- Build or install the program, using the steps above, and confirm the version you expect.
- Read the configuration settings in the source or build files before changing anything.
- Point the program only at test endpoints you control or have explicitly permitted to use.
- Start the miner and watch the console output for connection messages and error lines.
- Record what each line means, so you can compare runs after changes.
- Stop the program cleanly and review the logs before running it again.
- Remove the test folder or container when you finish, so no leftover setup remains on your system.
Pros & cons
- Free and open source, so the code can be read and checked
- Small Go codebase that suits study and experimentation
- Offered as a Windows build or installer, with Docker also listed
- Simple design makes the basic mining flow easy to follow
- No code updates since February 2020, so it is unmaintained
- Latest version is v1.3.0, which is several years old
- Built for developer testing, not for profit-focused mining
- Minimal feature set compared with larger miners
Is QLC Miner safe?
Mining software needs extra care because it runs with real resources and is often targeted by fake copies. Download QLC Miner only from the official website or the project's GitHub Releases page, and verify the SHA-256 checksum or signature against what the release publishes before you run anything.
The project itself is a risk factor. It has had no code updates since February 2020, so it will not receive fixes for issues found later. Check the latest version on the official website before you install, and read the code yourself if you plan to rely on it.
Antivirus tools often flag mining software, even legitimate tools. If your protection warns about the file, investigate the source and the hash instead of disabling protection entirely. Never enter a seed phrase on third-party websites or into any tool that asks for one.
- Official source only. Download from github.com/qlcchain/qlc-miner. Ignore ads and lookalike domains.
- Check the SHA-256. Compare the installer hash with the value the developer publishes before running it.
- Never share your seed phrase. No developer, support agent or website — including CryptApps — will ever ask for it.
Alternatives
Most programs in this category are built for production mining on specific hardware or algorithms. GMiner, NBMiner, T-Rex Miner, Rigel and WildRig Multi are GPU miners, and XMRig covers CPU and GPU mining for RandomX, KawPow and CryptoNight. NBMiner and T-Rex Miner have stopped development, so check status before you rely on any of them.
QLC Miner takes a different path. It is a minimal developer tool that does not aim at GPU or algorithm breadth, and it is meant for learning and testing rather than daily operation. Chia Blockchain is a different case altogether: it is a Python blockchain implementation with several components, not a general-purpose miner. Pick based on your goal, not on the name.

Frequently asked questions
Yes. QLC Miner is free and open source, so you can download, run and read its code without a purchase. Free use does not mean it is current, though. The project has had no code updates since February 2020, and its latest version is v1.3.0. Weigh that status before you install it on any machine you rely on.
It can be, if you verify the file before running it. Compare the SHA-256 checksum or signature against the value the project publishes, and keep antivirus protection turned on. Because the project is unmaintained, later-found issues will not be fixed. Never enter a seed phrase on third-party sites.
No. The most recent code update was in February 2020, and the latest version is v1.3.0. Bug fixes and compatibility changes for newer systems are therefore unlikely. If you need mining software that is still being developed, compare the alternatives on this page and check each project's status first.
The program is built for developer testing, not profit-focused mining, and this page makes no promises about earnings. Mining income depends on hardware, electricity costs, network conditions and pool rules, none of which the software controls. Treat QLC Miner as a learning tool rather than an income source.
Not for the ready-made Windows build or installer. Go and make are needed only when you build the program from the source repository with make clean build. Once the binary exists, you can run it without the build toolchain installed on your system.
Yes, the project is listed for Docker as well as Windows. Running it in a container keeps a test separate from your main system, which is useful for developers. Check the repository for current container instructions, and verify any image you pull before you use it.
Common alternatives in this catalog include XMRig for CPU and GPU mining of RandomX, KawPow and CryptoNight, and GMiner and Rigel for NVIDIA GPU mining. Choose by your hardware and target algorithm, and check each project's status before installing anything.
Verdict
QLC Miner for Windows is a small, free and open-source tool for developers who want to study or test a simple miner. It is not a practical choice for profit-focused mining, and the lack of updates since February 2020 is the main reason. Use it in a controlled environment, verify every download, and keep your system protection on. If you need a miner for ongoing use, compare the alternatives in the catalog and check each one's current status before you commit.
