This, however, means that their earnings can wildly vary from day to day. Now, here is a chart that shows how the Bitcoin and Ethereum mining revenues have compared with each other since the start of It seems like ETH miners have enjoyed a higher amount of revenue during the period Source: Arcane Research's The Weekly Update - Week 17, As you can see in the above graph, Ethereum miners have been raking in consistently more revenue than Bitcoin miners for quite a while now.

However, besides the revenue being more volatile, ETH mining has another, larger drawback. On the other hand, Bitcoin mining has a less uncertain future as the network is going to run proof-of-work for the foreseeable future. The below chart shows the trend in the price of the coin over the last five days.

In each cryptocurrency it is different, but in Ethereum it is given at the rate of 2 Ether for each block mined. Miners also occasionally receive Uncles reward for mining an uncle block. Uncle blocks are old blocks whose parents are at a maximum of six blocks before the current block and are rewarded to stop the delay that occurs as a result of spreading a valid block to the entire network.

Summary In order to establish what we have learned, we will summarize the 8 steps of mining. The miners: Verify that these can be carried out Store valid transactions in a block They compete by performing calculations to find the value Nonce Whoever gets it, spreads his block to the rest of the miners. If the majority considers it valid, it is added to the blockchain. The winning miner receives the reward of the block Start over! What is mining for? The main goal of mining is to keep the network stable through the general consensus of the network.

But it also serves to prevent the following types of attacks: Denial of Service DoS Denial of service DoS is a specific attack on a computer network that causes a system to become inactive. The main difference with its predecessor is that it is carried out from several computers to a single server, consuming all its bandwidth and leaving it inoperative. The Ethereum network and any project based on Blockchain is susceptible to such attacks.

Spam Spam, as we know it colloquially, would be the typical email with advertising that we usually receive repeatedly. It could also be the message that we find in a forum and that has nothing to do with its subject matter. However, in Ethereum network, Spam refers to the repetition of multiple transactions at the same time. For example, someone might try to spam by sending thousands of low-cost transactions simultaneously to destabilize the network.

However, transactions with very low costs are often not confirmed. Therefore, spam in Ethereum is possible but it is costly and useless in equal parts since the attacker would have to spend a large amount of Ether to carry it out and the reward obtained would be much less than what was spent.

Double Spending The so-called double spending is a failure that occurs by default in systems based on Blockchain, which consists of being able to spend more than once the same amount of digital currency.

Carlos has in his wallet 1 Ether and sends that same Ether simultaneously to two different people, Diego and Julia. If they are confirmed at the same time, both transactions would be valid, so there would have been double spending of the same Ether. How is this problem resolved? Waiting for up to 6 confirmations. When a transaction is processed, it is added to a block of transactions. Before being added to the original chain, the block must be verified by the rest of the miners.

When this block receives confirmations from up to 6 different miners, it can be considered valid. To prevent double spending, there will be one of those two transactions that will be verified up to 6 times. As soon as that happens, the other transaction will be processed as invalid automatically, so double spending will not be possible.

By avoiding these three risk factors, Ethereum is established as a system: Honest: Any attempt at self-profit to the detriment of the network will not be approved, so trying to cheat is ridiculous. Stable: Receiving 6 confirmations of the same transaction, the risk of cancellation is less than 0. How to start mining We will explain the steps to follow to start in the world of mining.

Create a digital wallet First of all, we need to create a wallet for receiving our mining rewards. Important: we must have the correct wallet for each cryptocurrency we want to mine. For example, we cannot use a Bitcoin wallet to receive Ethereum and vice versa. If we do not do it correctly, our rewards will be lost forever. Choosing hardware for mining The next step is to get special hardware for full-time mining.

There are three types of hardware for mining: ASICs Application-Specific Integrated Circuit are chips whose function is to perform a specific and particular task. These machines are the most widespread in Bitcoin mining. Of the three options, this is the least powerful and is hardly used for mining.

They have a higher hash rate than CPUs, which means they can solve mathematical problems faster. Before choosing our hardware to mine cryptocurrencies, we should consider different factors such as the hash rate, the initial cost of the hardware, its electricity consumption and its profitability.

This last factor will be discussed later. However, to help us do the math, mining profitability calculators such as Coinwarz or What To Mine show us the probable amount of cryptocurrency we can earn with certain mining power. If the result is positive when comparing the estimate obtained with the initial costs — equipment purchase, installation, electricity consumption, etc.

This method of keeping records on which Ethereum, Bitcoin and the rest of the cryptocurrencies are based avoids, among other things, the possibility of making double spending of the same money, a problem that went unresolved for a long time. However, the mining process changed the scene. What is mining?

Mining is the act of verifying transactions within a blockchain. Miners must use their powerful computer equipment to compete with each other and find the solution to complex mathematical problems before the rest. Whoever manages to find that solution will have solved the problem, so the transactions will be verified and added to the blockchain.

As a reward, they will receive a specific amount of the cryptocurrency they are mining. Proof of Work PoW is a method to avoid malicious behavior in a blockchain-based system. To do this, miners must do work that is very expensive for them, but easy for the rest of the community to verify. This work is computational -computer-related- and it costs them processing power, which can be turned into time, electricity and hardware.

How does mining work? To understand how mining works through this method we will divide it into several sections. Receive transaction requests On a Blockchain-based platform, each user can have one or more public addresses known as wallets.

Each public address has a private key associated with it. For easier understanding, this key could be something like our fingerprint, and the public address would be our smartphone. Just as only we can unlock our mobile with our fingerprint, in a blockchain, only the holder of that private key is able to digitally sign a new transaction request.

To make one of these requests, we must first have cryptocurrency entries. In other words, to transfer — for example — Ether, we first need to get Ether either buying it or transferred to our address. After that, we can use it to finance a new transaction. The miners collect all valid transaction requests and then go on to verify that the data from these transactions match.

Verification of data When they receive a transaction request, the miners check two things: first, that we have previously received in our wallet that amount from Ether, and second, that we have not already spent it. To verify this information, the miners go to the copy of the blockchain that each of them stores in their computer, which has recorded all the movements since its inception. In this way, they can know with precision if the operations can be carried out. Completing a block Once the data has been verified, the miner will add that valid operation to his transaction block.

To avoid the difficult task of corrupting a blockchain, its protocols make miners have to compete with each other to find the solution to the mathematical problem. The community of miners checks this data through the digital signature of the winning block.

They consist of three entries: The digital signature of the previous block The list of transactions valid from the previous block The Nonce value With these three entries, miners can add their block of transactions to the blockchain for validation and confirmation by the rest of the miners. These digital signatures operate through the use of hash functions: mathematical equations that take any given input and create a single output for that particular input.

Therefore, if the entries for the digital signature of a new block are the signature of the previous block, a list of recent transactions and the Nonce, the output will have a unique value that can only be obtained with the correct data. All miners know the first two entries but do not know the Nonce value.

Finding it is the reason they compete and this is done through their computer equipment. To guess this Nonce value, miners begin mathematical calculations: they create hashes from the two entries they know along with random Nonce estimates. The rest of the miners should check that both the operations included in the block and the digital signature are valid. If the great majority approves it, the block will be added to the blockchain in an immutable way.

In Ethereum, the target of this is to add a new block every 15 seconds on average. To prevent blocks from completing too fast or too slow, the protocol is reset after each block is added to make it easier or harder to guess the Nonce value. The opposite will happen if it takes longer than that time. Reward for mining Having understood all of the above processes, we will also understand why miners perform this task. As every worker get his or her own salary, the miners also need compensation for theirs.

In each cryptocurrency it is different, but in Ethereum it is given at the rate of 2 Ether for each block mined. Miners also occasionally receive Uncles reward for mining an uncle block. Uncle blocks are old blocks whose parents are at a maximum of six blocks before the current block and are rewarded to stop the delay that occurs as a result of spreading a valid block to the entire network. Summary In order to establish what we have learned, we will summarize the 8 steps of mining.

The miners: Verify that these can be carried out Store valid transactions in a block They compete by performing calculations to find the value Nonce Whoever gets it, spreads his block to the rest of the miners. If the majority considers it valid, it is added to the blockchain. It also supports dual mining, so when you become more experienced you can dual mine Ethereum Classic and Siacoin or Decred among others. This is the easiest solution, but also gives the lowest returns.

Plus Nanopool is one of the most popular mining pools, with global servers and enough history that I know they are trustworthy. First head over to Nanopool. When you click the appropriate button it will take you to GitHub to download the mining software. We will take a look at mining with both the Finminer and Claymore although the latter is preferred.

Using the Claymore Miner Once you have downloaded the Claymore files and unzipped them, you need to generate a configuration file to run it. There are a number of online tools that will help you to do this although conveniently, Nanopool has one as well. You can now go back to the Nanopool Quick Start menu and click the button under step 3 to generate your config file. This is the file that starts the miner and specifies the various parameters such as the server to connect to, and what Ethereum Classic address to send earnings to, and what address to send secondary earnings Siacoin or PascalCoin to.

Ethereum Classic Claymore Configuration Note that the secondary wallet field is mandatory, so you will need to choose either SiaCoin or PascalCoin and generate a wallet address. That could mean you need to download and install a SiaCoin or PascalCoin wallet. Once you click the Generate button another. You need to download this. Claymore miner hashing for ETC in Command line. Image Source The miner will go through several steps verifying the parameters and will then launch the mining software.

Much like with Claymore, you must download the. Once you have downloaded the files and extracted them then you need to configure the miner to run. Then open the config.
