Ethernet mining tutorial

1. Create a new folder on the hard disk, which is better than C: eth. Then all the mining software is stored here

2. Download the following software

1) geth -- select geth win download and unzip

2) ethernet -- download and unzip to the same folder and rename it as "miner"

3) Ethereum wallet -- Download the win Ethereum wallet and unzip it and rename it as "wallet"

install all the software

3 Open the command prompt (click win and R at the same time, or click Start menu and enter CMD). The command prompt is a command line parser that allows you to execute command input software in the operating system

After

, you will have Ethereum wallet. But there is no balance, so next you need to build an ethminer. It's time to minimize your wallet

Mining

2. At the top of Ethereum is DAPP. It exchanges with the smart contract layer through Web3. JS. All smart contracts run on EVM (Ethereum virtual machine) and use RPC calls. Below EVM and RPC are the four core contents of Ethereum, including: blockchain, consensus algorithm, mining and network layer. Except DAPP, all other parts are in the Ethereum client. The most popular Ethereum client is geth (go Ethereum)

3. Ethereum also uses blockchain technology, but it is more convenient to use than bitcoin's blockchain Turing, which is complete and open source. Anyone can create their own application on the basis of Ethereum

4. Build / env.sh go run build / ci.go install. / CMD / geth
make: * * [geth] error 1
there is no such directory, or the directory has insufficient permissions

5. Generally speaking, undefined index is the exact writing problem in the process of writing. Notice generally prompts for errors that are not directly related to the execution of code, but don't forget that notice sometimes returns some rendant error information

Generally speaking, the steps of deploying smart contract are as follows:

start an Ethereum node (such as geth or testrpc)
use Solc to compile smart contracts=& gt; Get the binary code
deploy the compiled contract to the network This step will consume Ethernet currency, and you need to use the default address or specified address of your node to sign the contract.)=& gt; Get the blockchain address and ABI of the contract (JSON representation of the contract interface, including variables, events and callable methods) The author confused ABI with contract interface here. ABI is the binary representation of the contract interface.)
use the JavaScript API provided by web3.js to call the contract Depending on the type of call, it may consume Ethernet currency.)

The

Ethereum mining

Berlin hard fork will mark the end of the metropolitan era. This is a key stage in Ethereum's history, which is divided into two stages (Byzantine and Constantinople), including several branches, including Atlantis, Istanbul, and finally reached its peak in Berlin

8. Virtual currency without instrial chain will certainly collapse

9. Ethiopia is located in the northeast of Africa, on the southwest coast of the Red Sea, bordering on Djibouti and Somalia in the East, Sudan in the north and West, and Kenya in the south, covering an area of over 1103600 square kilometers. The coastline of Ethiopia is 1013km long. The territory is mainly mountainous plateau, most of which belong to the Ethiopian plateau. The central and western regions are the main part of the plateau, accounting for 2 / 3 of the whole territory, with an average altitude of 2500-3000m; African roof & quot; It's called "the best of the best"< At the same time, ETH is the country code of the Federal Democratic Republic of Ethiopia in FIFA.
