Ethereum in Ubuntu

1.

Ethereum is an open source public blockchain platform with smart contract function. It provides decentralized virtual machine (Ethereum virtual machine) to process point-to-point contract through its special cryptocurrency ether (also known as "Ethereum")

The token on the

blockchain is called ether, and the code is eth. It can be traded in many foreign exchange markets of cryptocurrency, and it is also the medium used to pay transaction fees and computing services on Ethereum

the concept of Ethereum was first proposed by vitalik buterin, a programmer, from 2013 to 2014, inspired by bitcoin, with the general meaning of "next generation cryptocurrency and decentralized application platform", and began to develop through ICO crowdfunding in 2014. As of February 2018, Ethernet is the second highest cryptocurrency in market value, second only to bitcoin

extended data:

Ethereum platform has no characteristics and value. Like programming languages, it's up to entrepreneurs and developers to decide what to use. However, it is clear that some application types benefit more from the functions of Ethereum than others. Ethereum is especially suitable for those applications that automatically interact directly between points or promote group coordination activities across networks

for example, coordinate the application of point-to-point market, or the automation of complex financial contracts. Bitcoin enables indivials to exchange money without the help of financial institutions, banks or governments. The impact of Ethereum may be more profound

in theory, any complex financial activities or transactions can be automatically and reliably carried out on Ethereum with coding. In addition to financial applications, any application scenario with high requirements for trust, security and persistence, such as asset registration, voting, management and Internet of things, will be affected by Ethereum platform on a large scale

2. If IP is not automatically assigned, it needs to be manually filled in in the network management
click the network connection icon in the upper right corner to edit the connection, and then double-click your current wired connection to switch to the IPv4 interface and edit it.

4. sudo ./configure
sudo make
sudo make install

5. There is a space in the middle: ifconfig-a network card name is not necessarily eth0, it may be other name. If you don't see the network card, it means that the system doesn't recognize it, and you need to install another driver

6. You want a network card device, right
/ etc / network / interfaces
sudo VI / etc / network / interfaces
you can edit it and replace the line about eth0 with the following line:
? The primary network interface - use DHCP to find our address
auto eth0
Iface eth0 INET DHCP

use the following command to make the network settings effective:
sudo / etc / in It.d/networking restart
you can also directly enter the following command from the command line to get the address

7. How many network cards do you have? The cable network card starts from eth0.

8. I don't understand what you mean... If you start the eth0 instruction ifconifg eth0 up. If you do not recognize the network card.. Please install the NIC driver

9. If you want to see your network card, you can use: ifconfig - all view

you can use ifconfig eth1 & lt; ipaddress> netmask < netmask> Up command to enable your network card

thank you.

10. You can directly click the network icon in the upper right corner, select static IP and fill it in. Or you can directly modify the configuration file to set static IP, 1) edit / etc / network / interfaces 1.1) mask the primary network interface auto eth0 ᦇ Iface eth0 INET DHCP 1.2) add and static
