What is FPGA Mining and How Can You Make Money?

Cryptocurrency mining has come a long way since the early days of Bitcoin. Initially, mining was done using CPUs, then GPUs took over as they offered better performance. However, with the rise of FPGA (Field-Programmable Gate Array) technology, a new era of mining has begun. In this article, we will explore FPGA mining and its potential to revolutionize the cryptocurrency mining industry. AmazeWallet does not use FPGA mining—since most nodes run on everyday end-user devices including phones and laptops. But we still love the technology!

What is FPGA Mining?

FPGA mining involves using programmable chips to mine cryptocurrencies. Unlike CPUs and GPUs, which are designed for general-purpose computing, FPGA integrated circuits can be reprogrammed to perform specific tasks more efficiently. They are based around a matrix of configurable logic blocks (CLBs) connected via programmable interconnects. FPGA has been used for neural networks, hardware prototyping and acceleration, and even space avionics. For mining, the ability to reconfigure hardware is useful to optimise their mining algorithms and achieve higher hash rates with lower power consumption.

Intel and ARM (previously, Altera and Xilinx), are two of the leading manufacturers of FPGA chips. Though the technology is new, it holds a great deal of promise for several fields including cryptocurrency mining.

Pros and Cons of FPGA Mining

1. Efficiency: FPGA miners offer a significant improvement in energy efficiency compared to traditional mining hardware. With their ability to be reprogrammed, FPGAs can be fine-tuned to maximize performance while minimizing power consumption.

2. Versatility: Unlike ASIC (Application-Specific Integrated Circuit) miners, which are designed for a specific cryptocurrency algorithm, FPGAs can be programmed to mine multiple cryptocurrencies. This versatility allows miners to switch between different coins based on profitability, providing more flexibility in their mining operations.

3. Longevity: As new cryptocurrencies emerge, their mining algorithms often change to prevent ASIC miners from dominating the network. FPGAs, on the other hand, can adapt to these algorithm changes through reprogramming, making them more future-proof and capable of mining a wider range of cryptocurrencies.

4. Ease of use: FPGA mining requires significant understanding of both hardware as well as programming to set up. Other mining options, including AmazeWallet’s blockchain nodes that can run on the phone, are easier to get started.

5. Set up cost: FPGA circuits are not cheap, from several hundred to several thousand dollars per chipset, and require other hardware such as cooling, boards and more. There is no guarantee that after such initial costs, mining will be profitable—it can fluctuate significantly. 

FPGA Mining vs. GPU Mining

While GPUs have been the preferred choice for many miners, FPGA mining offers several advantages over GPU mining.

1. Performance: FPGAs can achieve higher hash rates compared to GPUs, resulting in faster mining and potentially higher profits.

2. Power Consumption: FPGAs are more power-efficient than GPUs, allowing miners to reduce their electricity costs and increase their overall profitability.

3. Flexibility: FPGAs can be reprogrammed to adapt to different mining algorithms, making them more versatile than GPUs. This flexibility enables miners to stay competitive in a rapidly evolving cryptocurrency landscape.

How to start FPGA mining

1. Research and Education

Before diving into FPGA mining, it’s crucial to understand the basics of cryptocurrencies, blockchain technology, and mining. Familiarize yourself with the different types of cryptocurrencies and their mining algorithms. This knowledge will help you choose the right FPGA board and mining software for your needs.

2. Choose the Right FPGA Board

Selecting the appropriate FPGA board is essential for successful mining. Look for FPGA boards that are compatible with the cryptocurrency you wish to mine and offer high-performance capabilities. Some popular FPGA boards for mining include Xilinx Virtex UltraScale+, Intel Stratix, and Lattice ECP5.

3. Set Up the Hardware

Once you have your FPGA board, you need to set it up correctly. Connect the board to your computer using the necessary cables and ensure that all drivers and software are installed. Follow the manufacturer’s instructions for proper installation and configuration.

4. Install Mining Software

Next, you’ll need to install mining software that is compatible with FPGA mining. Some popular options include CGMiner, BFGMiner, and EasyMiner. These software programs will allow you to control and monitor your FPGA board’s mining operations.

5. Join a Mining Pool

Joining a mining pool is highly recommended for FPGA miners, especially for beginners. Mining pools combine the computing power of multiple miners to increase the chances of finding blocks and receiving rewards. Some popular mining pools for FPGA mining include braiins pool, F2Pool, and Antpool.

6. Start Mining

Once everything is set up, it’s time to start mining. Launch your mining software, enter your mining pool’s details, and let your FPGA board do the work. Monitor your mining operations regularly to ensure everything is running smoothly.

The Future of FPGA Mining

As the cryptocurrency mining industry continues to evolve, FPGA mining is expected to play a significant role in shaping its future. With their energy efficiency, versatility, and adaptability, FPGAs offer a compelling alternative to traditional mining hardware.

However, it’s important to note that FPGA mining is still a relatively niche market. The initial setup costs and technical expertise required to program FPGAs can be barriers for entry for some miners. Additionally, as FPGA mining gains popularity, the competition may increase, potentially reducing profitability.

Nevertheless, FPGA mining holds great promise for the future of cryptocurrency mining. As technology advances and FPGA development becomes more accessible, we can expect to see more miners adopting this efficient and flexible mining solution.


In conclusion, FPGA mining represents a significant advancement in the field of cryptocurrency mining. Its energy efficiency, versatility, and adaptability make it a compelling choice for miners looking to optimize their mining operations. Whether FPGA is profitable depends on a number of factors, most notably the choice of algorithm, hardware investment, electricity/running costs and more.

While there are challenges to overcome, the future of FPGA mining looks promising, and it may very well become the preferred method of mining in the years to come. We believe that mobile phones are the key to blockchain scalability—but FPGA will surely play a key part in more technical mining operations.
