0xbitcoin Miner is a free, open-source program that mines ERC-20 tokens on your computer's processor. It is aimed at hobbyists who want to experiment with proof-of-work mining on Windows and Linux without buying dedicated graphics hardware. Because it runs on the CPU, it is better suited to learning how the process works than to earning meaningful income.
Be aware that the project has not received code updates since July 2021. That means it will not reflect newer network changes or security fixes. Treat it as a reference build for understanding how token mining works, and review the project's current state on GitHub before you commit any funds or hardware time to it.
What Is Proof-of-Work Token Mining?
Proof of work is a consensus method in which participants compete to solve computationally expensive puzzles. The first participant to find a valid solution is allowed to add a block of transactions or issue newly minted tokens, depending on the protocol.
For ERC-20 tokens built on Ethereum, this process typically means your computer repeatedly generates candidate solutions and checks them against a difficulty target. Most of the work is trial and error, which is why the speed of your hardware, measured as hashrate, has a direct effect on how often you find a solution.
Understanding this basic loop helps set realistic expectations. Mining is a probabilistic activity: results depend on difficulty, competition from other miners and how long your machine runs.
Who Is a CPU Miner Like This One For?
A CPU miner like 0xbitcoin Miner is mainly useful for people who want to learn how mining software operates. You can see the process in action, read the source code and understand what the software does with your processor without investing in specialized equipment.
Developers and students may find the codebase useful as an example of a JavaScript-based mining client. Hobbyists who already own a capable desktop can run it in the background as a low-stakes experiment.
People looking for consistent output usually turn to GPU miners, because graphics cards perform the same hashing work far more efficiently than a general-purpose CPU.
Why Mining Is Resource-Intensive
Mining keeps the processor under sustained load for hours at a time. That load produces heat, raises electricity consumption and can wear on cooling systems if fans are dusty or airflow is poor.
Before running any miner for an extended period, check your CPU temperature with a monitoring tool and make sure your cooling is adequate. Laptops are generally a poor choice, since they tend to throttle or overheat under continuous load.
Also consider the electricity cost in your region. A CPU that mines slowly while drawing significant power may not justify the expense, especially with low expected returns.

How to use 0xbitcoin Miner
Using 0xbitcoin Miner is mostly a matter of preparing the configuration and starting the process from a terminal. The steps below assume you have already completed installation and have Node.js available.
- Open a terminal window and navigate to the folder where you extracted the project.
- Copy the sample configuration file and rename the copy so the miner can read it.
- Open the configuration file in a text editor and enter your Ethereum address. If you do not have one, create it with a wallet such as Metamask, and keep your seed phrase offline.
- Adjust any parameters the sample file exposes, such as the number of threads, so they match your processor's capabilities.
- Save the file, return to the terminal and run npm run miner to start.
- Leave the terminal open while the miner runs, and check the output for errors or connection problems.
- Stop the miner with Ctrl+C when you want to pause. Review your results periodically rather than leaving the process unattended for long stretches.
Pros & cons
- Free and open-source under the GPL license
- Source code is available for inspection and modification
- Simple configuration through a single file
- Runs on Windows and Linux
- Useful as a learning tool for proof-of-work mining
- No code updates since July 2021
- Requires Node.js and terminal use, which may be unfamiliar to some users
- CPU mining is slow compared with GPU mining for the same tokens
- Heavy processor load can cause heat and higher electricity use
- Output is typically modest, so earnings are unlikely to be significant
Is 0xbitcoin Miner safe?
Because this program interacts with your computer's processes and with a cryptocurrency address, handle it carefully. Download only from the official GitHub repository, and verify the SHA-256 checksum or signature when the project publishes one. Never enter a seed phrase or private key on third-party websites or in response to unsolicited messages.
Mining software is frequently flagged by antivirus programs, sometimes as a false positive. If your security software blocks the miner, investigate the alert and consider the source code rather than disabling protection entirely. Since the project has not been updated since 2021, review the open issues and commit history on GitHub before running it.
- Official source only. Download from github.com/daikirifinance/0xbitcoin-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
Compared with the GPU miners in this catalog, 0xbitcoin Miner takes a fundamentally different approach. 0xbitcoin Gpuminer uses graphics cards to handle the same kind of work, which generally yields much higher throughput. Among the other GPU-focused tools, lolMiner and BzMiner are designed for broader hardware support, while Nanominer targets a range of algorithms with its own configuration format.
The key difference is hardware. If you want to learn how a CPU miner works or experiment without graphics hardware, this program is a reasonable starting point. If your goal is more serious throughput, a GPU miner from the catalog is the better fit, though it also carries higher power and cost requirements.
