In cryptocurrency mining, speed is important because miners are essentially trying to solve a question and get rewards before anyone else. The higher the hash rate, the greater your chances are of finding the next block and receiving a reward.

Some miners decide to set up a mining rig, which is a machine composed of several GPU units. A mining rig will increase your hash rate and therefore boost your chances of successful mining. The next step is to download the Ethereum blockchain and connect your node to the network. You can use a service like Geth, which continuously attempts to connect to other nodes on the network until it has peers.

Once installed, your node will be connected to all the other nodes and the Ethereum network itself. This allows you to start mining, deploy your own smart contracts, build decentralised apps, and send transactions. Test your mining capabilities Before you start mining, you can mine test Ether on your own private network. This enables you to test your mining capabilities, experiment with smart contracts, and try out new decentralised apps.

You are the only user in a private test network, meaning you are responsible for finding all the blocks, validating transactions, and executing smart contracts. Join a mining pool If you join a mining pool, you can pool your computational power with other miners to improve your chances of solving the cryptographic puzzles and earning Ether.

Ethereum Addresses Ethereum addresses are unique identifiers that are derived from public keys or contracts using the Keccak one-way hash function. Note It is worth noting that the public key is not formatted with the prefix hex 04 when the address is calculated. Unlike Bitcoin addresses, which are encoded in the user interface of all clients to include a built-in checksum to protect against mistyped addresses, Ethereum addresses are presented as raw hexadecimal without any checksum.

The rationale behind that decision was that Ethereum addresses would eventually be hidden behind abstractions such as name services at higher layers of the system and that checksums should be added at higher layers if necessary. In reality, these higher layers were developed too slowly and this design choice led to a number of problems in the early days of the ecosystem, including the loss of funds due to mistyped addresses and input validation errors.

Furthermore, because Ethereum name services were developed slower than initially expected, alternative encodings were adopted very slowly by wallet developers. ICAP addresses can encode Ethereum addresses or common names registered with an Ethereum name registry. IBAN is an international standard for identifying bank account numbers, mostly used for wire transfers.

IBAN is a centralized and heavily regulated service. ICAP is a decentralized but compatible implementation for Ethereum addresses. An IBAN consists of a string of up to 34 alphanumeric characters case-insensitive comprising a country code, checksum, and bank account identifier which is country-specific. Because this encoding fits less than the full bits of a general Ethereum address, it only works for Ethereum addresses that start with one or more zero bytes.

The advantage is that it is compatible with IBAN, in terms of the field length and checksum. Basic Same as the Direct encoding, except that it is 31 characters long. Indirect Encodes an identifier that resolves to an Ethereum address through a name registry provider.

It uses 16 alphanumeric characters, comprising an asset identifier e. We can use the helpeth command-line tool to create ICAP addresses. You can tell because it is 33 characters long. If our address did not start with a zero, it would be encoded with the Basic encoding, which would be 35 characters long and invalid as an IBAN. Tip The chances of any Ethereum address starting with a zero byte are 1 in At this time, ICAP is unfortunately only supported by a few wallets. EIP offers a backward-compatible checksum for Ethereum addresses by modifying the capitalization of the hexadecimal address.

The idea is that Ethereum addresses are case-insensitive and all wallets are supposed to accept Ethereum addresses expressed in capital or lowercase characters, without any difference in interpretation. By modifying the capitalization of the alphabetic characters in the address, we can convey a checksum that can be used to protect the integrity of the address against typing or reading mistakes. Wallets that do not support EIP checksums simply ignore the fact that the address contains mixed capitalization, but those that do support it can validate it and detect errors with a The mixed-capitals encoding is subtle and you may not notice it at first.

Some of the alphabetic A—F characters from the hexadecimal encoding alphabet are now capital, while others are lowercase. EIP is quite simple to implement.

Step Click the words according to their respective sequence as displayed in the Secret Backup Phrase box. Click Confirm. Step Once the Congratulations page appears, click All Done. Your Main Ethereum Network account page should appear. Step 2: On your Main Ethereum Network page, click the public key to copy on your clipboard. Step 3: Click the Export Private Key button.

Step 4: Enter your MetaMask password and then click Confirm. Step 5: Copy your Private Key, paste into a text file, and save in a secure location. If the executables are not moved then either navigate to the bin directory to run them e. These instructions can be ignored for other installations.

Background Geth is an Ethereum client written in Go. This means running Geth turns a computer into an Ethereum node. Ethereum is a peer-to-peer network where information is shared directly between nodes rather than being managed by a central server. On receiving a new block, each node checks that it is valid and adds it to their database.

There are two types of account: externally-owned accounts EOAs and contract accounts. Contract accounts execute contract code when they receive transactions. EOAs are accounts that users manage locally in order to sign and submit transactions. Each EOA is a public-private key pair, where the public key is used to derive a unique address for the user and the private key is used to protect the account and securely sign messages.

This tutorial will guide the user through creating an account, funding it with ether and sending some to another address. Read more about Ethereum accounts here. Step 1: Generating accounts To generate a new account in Geth: geth account new This returns a prompt for a password. In this tutorial the keys will be stored in a new data directory geth-tutorial. Your new account is locked with a password. Please give a password. Do not forget this password.

Others need it to interact with you. The key controls access to your funds! Without the key, it's impossible to access account funds! Without the password, it's impossible to decrypt the key! It is important to save the account address and the password somewhere secure.

They will be used again later in this tutorial. Please note that the account address shown in the code snippets above and later in this tutorials are examples - those generated by followers of this tutorial will be different. The account generated above can be used as the main account throughout the remainder of this tutorial.

However in order to demonstrate transactions between accounts it is also necessary to have a second account. A second account can be added to the same keystore by precisely repeating the previous steps, providing the same password. Notice that the path to the secret key includes a long filename that starts UTC This is the name of the file that contains the keys for the new account. It is extremely important that this file stays secure because it contains the secret key used to control access to any funds associated with the account.

The file should be backed up securely along with the password used to encrypt it. If the file or the password is lost, then so is access to the funds in the account. If someone else gains access to the keyfile and password, they have access to any assets in the account. Step 2: Start Geth Geth is the Ethereum client that will connect the computer to the Ethereum network. In this tutorial the network is Goerli, an Ethereum testnet. Testnets are used to test Ethereum client software and smart contracts in an environment where no real-world value is at risk.

To start Geth, run the Geth executable file passing argument that define the data directory where Geth should save blockchain data , the network ID and the sync mode. For this tutorial, snap sync is recommended see here for reasons why. The following command should be run in the terminal: geth --datadir geth-tutorial --goerli --syncmode snap Running the above command starts Geth.

The terminal should rapidly fill with status updates that look like the following: INFO [ INFO [ Once it finds peers it can request block headers from them, starting at the genesis block for the Goerli blockchain. This is confirmed by the logs printed to the terminal. There should be a rapidly-growing sequence of logs in the terminal with the following syntax: INFO [][ If there is no error message reported to the terminal, everything is OK. Geth must be running in order for a user to interact with the Ethereum network.

If this terminal is closed down then Geth must be restarted again. Geth can be started and stopped easily, but it must be running for any interaction with Ethereum to take place. To start it again, run the previous command geth --datadir You can also try doing a light sync which will be much quicker but depends on light servers being available to serve your node the data it needs. Step 3: Get Testnet Ether In order to make some transactions, the user must fund their account with ether.

On Ethereum testnets, the ether has no real world value so it can be made freely available via faucets. Faucets allow users to request a transfer of testnet ether to their account. The address generated by geth account new can be pasted into the Paradigm Multifaucet faucet here. This requires a Twitter login as proof of personhood.

The faucets adds ether to the given address on multiple testnets simultaneously, including Goerli.
