Ethereum Mining
Ethereum Mining: is the process of generating a block of transactions that will be added to the Ethereum blockchain later. it is like Bitcoin, presently employs a Proof of Work consensus method (PoW). However, the heart of Proof of Work is mining. Ethereum miners (computers that operate the software) dedicate their time and computational resources to processing transactions and generating blocks.
How to mine Ethereum
How to mine Ethereum: A beginner’s guide to ETH mining Cryptocurrency mining is a process by which complex mathematical problems are sought to be solved. Therefore, miners are a fundamental part of any cryptocurrency system that operates within a Blockchain network. By contributing their time and computing power to solve those math problems, they provide a so-called ” proof of work ” for the web, verifying Ether transactions. Additionally, miners are responsible for creating new Ether tokens through this process, as they receive Ether rewards for completing a proof-of-work task.
Why do Miners Exist
In decentralized systems like Ethereum, we need to ensure that everyone agrees on the order of transactions. Miners help make this happen by solving challenging computer puzzles to produce blocks to protect the network from attack.
A Bit about Ethereum
The miners apply their computational power to solve the mathematical puzzle for each transaction block.
To be more specific, miners take the metadata of each block’s unique headers. These data establish a timestamp and software version through a hash function, which generates a fixed-length string of random numbers and letters. Case sensitive. This chain is called a hash, and if the miner finds a hash that matches the current target, the block will be considered mined and broadcast to the entire network for other nodes to validate and add the transaction to their copy of the blockchain.
Ethereum Mining Hardware
Before we start, we will have to choose the dedicated hardware to set up our computer for full-time mining. There are two options: CPU (Central Processing Unit), which means using our computer’s processor, and GPU (Graphics Processing Unit), which will mean buying an expensive graphics card.
It is important to note that mining Ether with CPUs is currently not profitable, as even the most basic GPUs are around 200 times faster than mining CPUs. Therefore, before buying a graphics card, we need to consider the costs associated with the purchase itself and power consumption. The most important thing that we will have to consider is the performance of the hash rate, which is the speed at which the mathematical problem will be solved.
We might also consider installing a mining rig; a machine made up of multiple GPU units to increase your hash rate and, by extension, your chances of mining success.
Once we have chosen and bought the hardware, we will have to install the software. First of all, we will need drivers for our graphics card, which we can find on the manufacturer’s website or find together with the card itself.
Next, we will need to configure the node and connect it to the network. We will download the entire Ethereum blockchain, which is currently over 132 GB in size and continues to grow over time. Next, we will need to connect the node to the network. There are several ways to do it. Users familiar with the command line can fit Geth, with other services like MinerGate or Ethermine also available.
Once configured, our node will be connected to all other nodes and the network itself. This will allow us to start mining and implementing your smart contracts, create decentralized applications, and send transactions.
Tests
Before starting Ether mining, it is possible to set up a private test net. It is a handy tool if we want to test intelligent contracts, develop a new technology or test our mining capabilities. Although we are the only users in a private test net, which means we are responsible for finding all blocks, validating all transactions, and executing smart contracts, it is an Ethereum sandbox. Currently, this is done via a command line, with services like Geth providing such options.
Knowing at least an approximate hash rate of our device will also help when it comes to calculating the potential benefits that we can obtain in the network. We can use this profitability calculator, which will automatically calculate using our hash rate based on the hardware we are using and the electricity costs of the country we are in. Essentially, we will need the highest hash rate possible. The higher it is, the more profit we can make from mining Ether.
How Transactions Mine on Ethereum
Upon learning of the new transaction request. Each node on the Ethereum network adds appeal to its local temporary databases. This list includes all transaction requests for which information obtain but not yet completed. Have committed to the blockchain of a block.
A mining node adds several tens or hundreds of transactions at some point. Requests to a potential block in a way that maximizes the transaction fees. They earn while remaining under the block’s gas limit. Next, the mining node must:
Check the integrity of each transaction request. No one is trying to transfer ether from an account for which you have not produced a request signature, etc.). And then execute the request code, altering the state of your local copy of the EVM. Then, the miner grants the transaction fee for each transaction request to his account.
Start producing the Proof-of-Work certificate of legitimacy for the potential block. Once all transaction requests in the league have been verified. And executed on the local copy of the EVM.
At some point in the prospect. A miner will finish producing a certificate for a block that includes our specific transaction request. The miner then transmits the entire league. Including the certificate and a checksum of the new state of the mentioned EVM.
