As difficulty increased over time for mining Ether, mining rigs with multiple GPUs were starting to be built by the miners.
A mining rig usually contains around five GPU cards with all of them working in parallel for mining, thus improving the chances of finding valid nonces for mining.
A Complete Guide to Understanding This Blockchain Concept
Mining rigs can be built with some effort and are also available commercially from various vendors.
A typical mining rig configuration includes the components discussed here: Motherboard: A specialized motherboard with multiple PCI-E x1 or x16 slots, for example, BIOSTAR Hi-Fi or ASRock H81, is required.
The SSD drive is recommended because of its much faster performance over the analog equivalent.
It is recommended that you have roughly 250 GB of free space on the hard disk.
GPU: The GPU is the most critical component of the rig as it is the primary workhorse that will be used for mining.
For example, it can be a Sapphire AMD Radeon R9 380 with 4 GB RAM.
Why This Matters for Blockchain Technology
A website that maintains these benchmark metrics is available at .
Also, it allows you to run a bare minimum operating system required for mining, and essential operations as compared to heavy graphical interfaces that another operating system may have.
There is also another variant of Linux available, called EthOS (available at ) that is specially built for Ethereum mining and http://ethosdistro.com/ supports mining operations natively.
Mining software: Finally, mining software such as Ethminer and Geth are installed.

Going Deeper: Advanced Concepts
Additionally, some remote monitoring and administration software are also installed so that rigs can be monitored and managed remotely if required.
It is also important to put proper air conditioning or cooling mechanisms in place as running multiple GPUs can generate a large amount of heat.
This also necessitates the need for using an appropriate monitoring software that can alert users if there are any problems with the hardware, for example, if the GPUs are overheating.
Power Supply Units (PSUs): In a mining rig there are multiple GPUs running in parallel, therefore there is a need for a constant powerful supply of electricity.
Conclusion
Mining rigs represents one of the many innovative layers that make blockchain technology so powerful and transformative. As distributed systems continue to evolve, a solid understanding of these core concepts becomes increasingly valuable — not just for developers, but for anyone building, investing in, or working alongside blockchain-powered systems.
Whether you are just starting your blockchain journey or deepening existing expertise, mastering these fundamentals gives you the tools to think clearly about decentralized systems and make smarter decisions in this rapidly evolving space.
