Safex Miner is a free, open-source CPU mining program for the SAFEX network, built for people who want a simple way to mine with their processor on Windows. It is released under the MIT license and offered as a Windows build or installer, with versions listed for macOS and Linux as well.
Before you install it, know its status: the code has not been updated since December 17, 2018, and the latest release is v.0.0.2. That makes this an old project, best treated as a historical tool rather than a maintained one. Read the safety notes below before running it on a machine you care about.
How Proof-of-Work CPU Mining Works
Proof-of-work networks ask participants to repeat a computational task until someone finds a valid result. Miners who contribute computing power compete for the right to add a block, and the network rewards the successful one. Mining software is the program that runs this calculation on your hardware and reports results.
The key measure is hashrate, the number of attempts a device makes per second. CPUs generally produce a lower hashrate than graphics cards, which is why many miners who use GPUs choose dedicated GPU tools. Mining difficulty adjusts over time, so the same hardware can produce different outcomes as a network changes.
Many miners join a mining pool, where participants combine their hashrate and share rewards in proportion to their contribution. Solo mining is possible but less predictable. Whichever approach you choose, results depend on network conditions, hardware and electricity costs, and no program can promise a profit.
Who Safex Miner Is For
Safex Miner suits a few specific groups. The first is a hobbyist who wants to see how CPU mining works on a home computer, using a simple interface instead of configuration files. Running a small test on a spare machine can show the basic workflow before you commit to anything larger.
The second group is developers and students. Because the project is MIT-licensed and published on GitHub, the source code can be read, studied and modified. That makes it useful as a learning resource for how a desktop mining client is put together.
It is less suitable for anyone who needs current security patches, support for new networks or a tool that tracks ongoing development. Those readers should look at actively maintained alternatives listed below.
Key features
One-Click CPU Mining
Desktop App Built With Electron
Supported coins
The program is built for mining SAFEX, the network it is named after, and it is described as a CPU miner rather than a multi-coin tool. If you plan to mine other coins, a dedicated miner that lists those algorithms is a better fit. The comparison section below covers alternatives.
How to install Safex Miner on Windows
- 1
Get the official build
Download only from the official website or the project's GitHub Releases page. Choose the Windows build or installer, and avoid mirror sites, file-sharing links and downloads shared in chats or forums.
- 2
Verify the file
If the release publishes a SHA-256 checksum or signature, compare it with your download. In Windows PowerShell, Get-FileHash -Algorithm SHA256 followed by the file path prints the hash. A mismatch means you should not run the file.
-
Install and launch
Run the installer, or extract the build to a folder you control, then open Safex Miner. If Windows SmartScreen or antivirus software warns you, check the source and hash first rather than disabling protection altogether.
How to use Safex Miner
Setting up a miner takes only a few minutes, but the order of steps matters. Follow them so you know where the files came from and what the program is doing.
- Download the Windows build or installer from the official GitHub Releases page.
- Compare the file's SHA-256 checksum with the value published by the project, if one is available.
- Install the program to a folder you can find later, or extract the build into one.
- Open Safex Miner and review the settings screen before starting any mining session.
- Start mining with your processor and leave the program running for a short test period.
- Watch CPU temperature and fan noise, and stop the program if the system becomes unstable.
- Close the program when finished, and keep a record of the version you installed.
Pros & cons
- Free to use and released under the MIT license, so the source code is open to inspection
- Designed as a one-click CPU mining app, which keeps the start-up process simple
- Available as a Windows build or installer, with macOS and Linux versions listed as well
- Built with Electron, giving it a conventional desktop window instead of a command-line-only interface
- No code updates since December 2018, so security and compatibility fixes are absent
- Focused on the SAFEX network, so it is not a general multi-coin miner
- CPU mining generally produces a lower hashrate than GPU mining
- Mining software is often flagged by antivirus tools, which can make installation more confusing
Is Safex Miner safe?
Safex Miner has not received code updates since 2018, so treat it with more caution than a maintained tool. Download only from the official website or the project's GitHub Releases page, never from mirror sites or links shared in chats. Compare the file's SHA-256 checksum or signature with the value the project publishes, and do not run a file that fails the check.
Antivirus software often flags mining programs. Treat that warning as a reason to check the source and hash of the file, not as a reason to turn protection off entirely. Keep your security tools running. Never enter a seed phrase or private key on a third-party website, and a miner has no legitimate reason to ask for one. Check the latest version on the official website before installing.
- Official source only. Download from github.com/safex/safex_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
Safex Miner is narrower than most tools in this category. It targets SAFEX on the CPU, while XMRig is described as a CPU and GPU miner that supports RandomX, KawPow and CryptoNight, which makes it a broader choice for people who want several algorithms. GMiner, Rigel, NBMiner, T-Rex Miner and WildRig Multi are GPU-focused tools for graphics cards, so they answer a different hardware question. Chia Blockchain is not a miner in the same sense; it is a full node and farming stack. Safex Miner's advantage is its simplicity for one network on a processor, and its main drawback is the lack of recent updates.

Frequently asked questions
Yes. Safex Miner is free and released under the MIT license, which allows the source code to be read and reused under its terms. Download it only from the official website or the project's GitHub Releases page to avoid modified copies.
It can be used with care, but the project has had no code updates since 2018. Verify the file's SHA-256 checksum or signature, download from the official source, and keep antivirus protection active. Never enter a seed phrase on a third-party site.
No. The last code update was on December 17, 2018, and the latest release is v.0.0.2. The project is best treated as a historical tool rather than one receiving regular fixes.
It is built for the SAFEX network and described as a CPU mining app for that network. If you want to mine other coins, look at a dedicated miner that lists those algorithms, such as XMRig for several CPU and GPU algorithms.
Antivirus tools often flag mining software because its behavior, which uses a lot of processor time, resembles some malicious programs. A flag is a reason to verify the file. Check the source and hash, and do not disable your protection entirely.
No one can promise a profit. CPU mining generally produces less hashrate than GPU mining, and results depend on network difficulty, hardware, power costs and pool fees. Test carefully on a spare machine before relying on any result.
Verdict
Safex Miner is best for curious users who want a simple, free way to try CPU mining for the SAFEX network on Windows, and for developers who want to read an MIT-licensed mining client. It is not a good pick for anyone who needs current updates, broad coin support or active security maintenance. If you choose it, verify the download, keep your protection running and treat the program as a learning tool. Check the latest version on the official website before installing.
