When it comes to investing in Ethereum, mining is one of the more popular ways. It is the activity of dedicating computing resources toward the verification of transactions and generating new Ethereum blocks. It also entails contributing to the governance and security of the network.
This detailed guide will learn about the unique features of mining Ethereum and how different it is from mining Bitcoin. We’ll take you through things to consider before investing in Ethereum mining, such as hardware, software, and the mining community.
Ethereum is a decentralized autonomous blockchain network comprised of three parties:
The developers create the code and implement technical changes to the network. The miners help generate the new coins, confirm transactions and contribute to the governance of the blockchain. Users take advantage of the selling proposition of the network. In Ethereum’s case, it is a platform that hosts smart contracts.
Smart contracts are pieces of code that execute automatically when a specific set of conditions is met. They utilize Ethereum’s global computing network.
Ethereum also provides a decentralized digital currency called Ether (ETH) to facilitate value exchange within the network or cryptocurrency exchanges.
The three components of the Ethereum network are interdependent and have to work together in harmony all the time. If the developers stop contributing to the network, it will fail. The same case happens if miners stop mining or users abandon the community.
Cryptocurrency mining means dispensing computing resources towards solving complex math challenges. Since there are several miners in the network, the first one to solve the challenge is to create the next block and be rewarded with new ETH coins. This type of mining is referred to as Proof of Work (PoW).
Additionally, mining in the Ethereum network also means verifying and validating transactions. Every transaction performed has to be verified before it’s included in the blockchain. For this activity, miners are compensated with transaction fees.
Both individual users and smart contracts have to pay network fees to have their transactions included in the blockchain.
As described above, we can identify three types of rewards to Ethereum miners:
We’ve stated above that Ethereum uses the popular PoW consensus mechanism to facilitate block generation. This method has its pros and cons. However, according to the Ethereum core developers, it seems to have more cons than pros.
The biggest con is that it is not scalable in its current implementation. Ethereum is a Turing Complete blockchain that allows other decentralized applications (dApps) to run on its network. It needs to be fast to achieve this.
To solve this problem, the developers upgrade the network to Ethereum 2.0 that implements the Proof of Stake (PoS) consensus mechanism. PoS uses staking instead of the mining as a means to secure and scale the network.
There are two aspects of PoW mining that are essential to understand. These are:
The two factors are directly correlated to one another. The network difficulty trails the hash rate, as an increase (or decrease) in hash rate, causes a subsequent increase (or decrease) in the difficulty score.
Network difficulty is essential in regulating block generation time. Ethereum’s blocks are created every ~14 seconds, and whenever this number rises or falls, the difficulty automatically adjusts appropriately.
Bitcoin and Ethereum have many similarities. They are both public blockchains. They both have native cryptocurrencies used for value exchange, and they both use the Proof of Work consensus mechanism.
This is about the extent of similarity that the two networks share. They have a lot more differences than they do similarities. Here are some of them:
Bitcoin’s SHA-256 allows for the use of highly specialized equipment called ASICs (Application Specific Integrated Circuit chips). Ethereum, on the other hand, can be mined using GPUs (Graphical Processing Units). ASICs are much more powerful and expensive compared to GPUs.
Ethereum core developers are upgrading the network to Ethereum 2.0, which will mean the end of mining in favor of staking through the PoS consensus mechanism. In this mechanism, individuals or institutions interested in verifying Ethereum transactions will be required to stake Ether.
Additionally, an Ethereum block is significantly smaller than a Bitcoin block at roughly 45Kb and 1.0Mb, respectively.
The above points are not the only differences between Ethereum and Bitcoin mining. However, these are the main.
There are three ways to mine Ethereum (and any other cryptocurrency that supports a PoW consensus). They are:
Mining Ethereum solo is highly discouraged unless you are able to set up an industrial-grade mining operation. The hash rate required to mine a block on Ethereum has grown past the hobbyist level, and anyone trying to mine solo may have to do so for a very long time to see any returns.
However, not all pools are recommended. Here are the factors to consider when looking for a mining pool to join:

PROS: Here’s why you might opt to invest in a cloud mining company:
CONS: The disadvantages of cloud mining include:
There are so many different wallets in the market today that will help you store your Ether. However, most are not ideal for a miner’s needs. Miners often hold their mined coins for medium to longer-term periods. The safety of these assets is paramount.
In this section, we will highlight the subtypes of cold wallets that are ideal for miners. If you need a more detailed look into the different wallets, check out our guide on ‘How to buy Ethereum Safely.’
A wallet is considered either hot or cold, depending on its connectivity to the internet. Hot wallets can be accessed remotely through the internet, making them less secure to store Ether for the medium to long term. Hot wallets include web, mobile and desktop wallets.
On the other hand, cold wallets are safer to use since they are inaccessible over the internet. They include hardware wallets such as Ledger Nano S and Trezor, paper and steel wallets like ColdTi, Billfodls, or SteelWallet.
Ethereum wallets can be either full or light nodes. Full node wallets are designed to download the entire Ethereum ledger onto the device in which they are installed. An example is Mist, the official Ethereum wallet.
Light node wallets do not store a full copy of the Ethereum ledger. Instead, they refer to other trusted full nodes. This makes them easier to download and operate. Most Ethereum wallets are light, including the Ledger Nano S and Trezor wallets we mentioned above. All mobile and web wallets are light nodes.
Choosing the right hardware for your Ethereum mining activities is essential. This is because the wrong hardware could mean the difference between being profitable and losing money.
When considering the perfect hardware for you, the most significant factors to consider will be price, availability, and performance. There are two major brands to choose from – AMD and Nvidia. Both of these are well known for their graphics cards which are popular with gamers.
AMD cards are generally cheaper but more versatile than Nvidia’s, meaning that they can mine several other cryptocurrencies. Nvidia cards, however, trumps AMD’s in terms of performance.
Better performance often means more energy consumption which increases mining costs and eats into your profits. To be profitable, a miner needs to strike the right balance amongst all these factors. To know which card best suits your situation, use a profitability calculator.
You can get profit estimates for almost any mining equipment online. If the specific card you are considering is relatively new with no prior metrics, you can use the calculator above from CryptoCompare. Just plug in the paper specifications from the manufacturer’s website and energy price in your region.
A profit calculator is essential in deciding which mining GPU to invest in based on your profitability targets.
Another significant consideration for mining hardware is the amount of VRAM that comes onboard the graphics card. Due to the Ethash mining algorithm used to mine Ether coins, there is a DAG (directed acyclic graph) file that has to be stored in every card. The DAG file is updated every 30,000 blocks, and its size is now just over 4Gbs. This means that every GPU under consideration has to have at least 6GBs of VRAM to mine Ether.
Most computer hardware components need companion software to communicate effectively with a computer’s other components. The software designed to perform this task is called a driver.
Each manufacturer creates a companion driver for its hardware. Both AMD and Nvidia have repositories for all versions of their hardware as well as target operating systems.
Visit the following support pages from either manufacturer to download the latest versions of drivers for your chosen hardware: AMD | Nvidia
Make sure to download the correct driver depending on your operating system and GPU card.

Mining clients are different from drivers. While drivers help the graphics cards communicate effectively with the computer, the mining software (also called a client or miner) allows the computer to communicate with the Ethereum blockchain.
These are some of the mining clients to consider:
Claymore receives regular software updates and is one of the most optimized Ethereum miners. It is a popular option. Experiment with most of these choices and find the one that works best for your mining setup. Each software comes with detailed instructions on how to install and set up the computer for mining.
Note: Ensure that you download the correct miner from the official repository. Use the links provided above. Do not download any miner from a third-party vendor.
At the moment, mining Ethereum can be done on either Windows or Linux operating systems. Windows is the more popular option given its ease of use and appealing interface, but Linux gives users more advanced settings and greater control of their mining rigs. It’s best suited for advanced miners.
Now that you have everything in place – your wallet installed, hardware installed and configured, and the mining client installed – there is one last step to go.
Your operating system’s default settings may not be ideal for mining and therefore require some changes. These changes include:

The final step to mining Ethereum is joining a mining pool. Earlier, we mentioned that joining a mining pool is the best way to mine Ether. It is possible to mine ETH alone, but it is not likely you will succeed.
Revisit the section above on the “Ways of mining Ethereum” for some things to consider when choosing a mining pool to join.
Here are three popular mining pools (TH/s at the time of writing):
Each pool will have a specific setup guide and possibly a list of stratum servers you will need to connect. You can find this information on their websites. Within these instructions, you will find other details, such as instructions for editing your miner files,
changing your mining address and the mining rig name.
All mining pools provide their users with a balance inquiry feature. For instance, with Ethermine, you can input your wallet address on the search bar on the top right-hand side to check how much ETH you have mined.
Additionally, if the coins have been sent to your wallet, you can use conventional blockchain explorers such as Etherscan.io to check your balance.
In the ongoing upgrade to Ethereum 2.0, the popular PoW consensus mechanism will become obsolete in favor of Proof of Stake (PoS). Ethereum’s core developers argue that PoS has several advantages over PoW. These include:
Ethereum 2.0 is rolling out in three phases – 0, 1, and 2. Phase 0 (called BeaconChain) launched in December 2020. Phases 0 and 1 will see both Eth1 and Eth2.0 run concurrently. It is only in Phase 2 that Eth1.0 will be fully deprecated and replaced by Ethereum 2.0.
Given Ethereum core developers’ history of implementing the Ethereum roadmap, it is hard to tell when the rest of the phases will launch. They are, however, proposed to roll out in 2021 and 2022 for phases 1 and 2, respectively.
This means that if you are mining Ether using GPU or considering it, you have until 2022 to mine Ether. Once Ethereum 2.0 launches, ETH miners will have to repurpose their gear towards mining other PoW coins or consider becoming stakers instead.
There you have it, your detailed guide to mining Ethereum. You have learned what it means to mine ETH, the various ways to do it, and what to consider before starting.
We also covered the mining setup from choosing the perfect Ethereum mining equipment, installing it, and configuring it correctly.
Finally, we highlighted the highly anticipated network upgrade to Ethereum 2.0, which uses PoS instead of PoW for transaction verification and validation.
You are now ready to start mining and staking Ethereum.
