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. Gas & gt; ethestimateGas({ from:ethaccounts [1], to: ethaccounts[2], value:50000000000000 }) 21001 > Ethgasprice 2000000000, as shown above, shows this account [1] = & gt; The transaction of account [2] needs 21001 gas, and the current gasprice is 2000000000. How many gas does it take to send transaction / call contract method in Ethereum

investment in bitcoin is not so profitable now. All the financial procts I know belong to usury, and those with an annual rate of more than 24% are generally not protected by the state. As far as I know, the monthly profit of 30% are all pyramid schemes, such as BBT mint
of course, maybe you will refute me, because you do get the benefits, but if you don't get the benefits, will you invest more money, or will you pull the head? This can go to the network about the Ponzi scheme.

5. Return the result of ifconfig
eth0 to awk for processing
where - F & # 39;:|< br />+'
this is a separator defined by awk and then matched with "BCAST & quot;, Take the content of the fourth column
since your command is not universal, you can't output the result here, but you should intercept the broadcast address

6. There are many motherboards in this series. It is recommended to determine the suffix of motherboard. C.h81m
Pro is all solid-state version, but the suffix is vxx or something. Then log in to Qicaihong website to see the relevant BIOS version. Some models provide overclocking BIOS.

7.

Check the established bond information. The general information is as follows:

cat / proc / net / bonding / eth1

Ethernet channel bonding driver: v3.4.0 (October 7, 2008)

Bonding Mode: fault-tolerance (active-backup)

Primary Slave: eth2

Currently Active Slave: eth2

MII Status: up

MII Polling Interval (ms): 100

Up Delay (ms): 0

Down Delay (ms): 0

Slave Interface: eth2

MII Status: up

Link Failure Count: 0

Permanent HW addr: 00:0c:29: DB: 30:5a

slave interface: eth3

MII status: up

link failure count: 0

permanent HW addr: 00:0c: 29: DB: 30:64

< P > if the bond is not established, Using

nmcli dev disconnect eth1

nmcli dev connect eth1

Service restart network

linux gets support from software lovers, organizations and companies all over the world. In addition to maintaining a strong momentum of development in the server, it has made great progress in personal computers and embedded systems. Users can not only intuitively obtain the implementation mechanism of the operating system, but also modify and improve Linux according to their own needs to make it adapt to the needs of users to the maximum

linux is not only stable, but also open source software. Its core firewall component has high performance and simple configuration, which ensures the security of the system. In many enterprise networks, in order to pursue speed and security, Linux is not only used as a server by network operation and maintenance personnel, Linux can be used as both a server and a network firewall, which is a highlight of Linux

8. The difference between INTERVALUE and EOS lies in that the underlying protocol project of EOS takes Ethereum as the blueprint and iterates on this basis, but it has not yet reached the standard of 3.0 era (i.e. blockchain application extension), which is far away from the practical implementation of blockchain technology in various instries and fields, i.e. blockchain 4.0. The value of INTERVALUE interconnection focuses on the core technologies of blockchain infrastructure and platform layer. In the form of public chain, alliance chain and private chain, it is applied to the blockchain 4.0 infrastructure of practical application scenarios and the blockchain 4.0 ecosystem supporting applications on various chains.
