1. Enjin (enj)

in the near future, the game instry is the instry most likely to adopt blockchain on a large scale. Enjin coin is the cryptocurrency of virtual goods created by Enjin. Enjin is the "largest online gaming community platform" with more than 250000 gaming communities and 18.7 million registered gamers

Cardano (ADA)

compared with Ethereum, EOS and Tron, Cardano is the third generation of decentralized app (DAPP) and smart contract platform. Cardano's design philosophy has the following points:

scalability: with the growth of users, the transaction processing speed is not affected or even faster, such as P2P protocol

interoperability: in the future, there will be countless devices connected to each other, instead of only connecting and forwarding through routers. All kinds of devices can communicate directly through standard general protocol

Sustainability: like bitcoin, Cardano project will not be controlled and influenced by a certain company or organization, which is a safe, decentralized and sustainable development platform

With the popularity of sto (security token offers), Nash also plays an important role. Nash is a kind of registered security token. In the past, Nash participated in and led the development of many projects

Nash exchange is a decentralized exchange. If you hold nex token, you can calculate the dividend here

4. Basic attention token (BAT)

bat mainly solves the problem of advertising:

user information is abused: large companies such as Google and Facebook track and use user information and behavior, and sell without the knowledge of users

the effect of advertising is restrained: middlemen earn most of the fees, a large number of advertisements are blocked by users using software, and advertisements are fake

in the past six to 12 months, the number of publishers using the brand browser (Note: the brand browser supports bat token) has grown rapidly, and almost no blockchain ecosystem has grown so fast

5, chainlink (link)

chainlink mainly solves the problem that each blockchain has and the smart contract cannot obtain external data. In order to introce external data into the blockchain, the concept of Oracle is proposed in smart contract

companies including Google are supporting the development of chainlink. Here is a list of chainlink partners

one of the main problems of chainlink is similar to Ethereum. The development team has reserved 650 million link tokens, while only 350 million are in circulation at present

Ethereum (ETH)

Ethereum has long occupied the second place in the top 100 cryptocurrencies. Its ecology is so big that we can't call it altcoin now. To tell you the truth, I'm not optimistic about Ethereum in the long run, but it will flourish in the short run

2. From the development stage of modern science and technology, innovation comes from the private sector, private digital currency develops first, and the central bank's digital currency rapidly becomes the mainstream form of digital currency by virtue of its sovereign advantage, which is the basic path of digital currency evolution.

3. Digital currency is the proct of currency development to a certain stage. The issuance of digital currency is mainly to make transportation more convenient and also concive to the supervision of the economy.

4.

Generally, the excellent digital currencies are mostly imported procts, such as bitcoin, Leyte coin, ether coin and so on. However, the domestic Yuanbao coin, Ruitai coin, bitcoin and the tokens of different crowdfunding projects of European crowdfunding are excellent digital currencies

digital currency (English: digital currency) is an alternative currency in the form of electronic currency. At present, no central bank of any government has indicated that it will issue digital currency, and digital currency does not have to have a benchmark currency and a central bank

it is different from the virtual currency in the virtual world, because it can be used for real goods and services transactions, not limited to online games. The early digital currency (digital gold currency) is a form of electronic currency named after the weight of gold. Today's digital currency, such as bitcoin, lightcoin and ppcoin, is an electronic currency created, issued and circulated by check sum cryptography

7. I want to know why your eth equipment is shown in red, while mine is shown in gray and marked with eth
in the past, I had a Diablo mod version, but it changed the settings of hackmap after installation. At that time, ETH equipment became scarlet letter, and weather effects still existed after hackmap was turned on, which made me angry. It was useless to reload hackmap. Finally, I reloaded the Diablo, which made me angry when I thought about it~~~~

8.

This is a Linux system IP address configuration command. The specific meaning is:

set the IP address of the system to 192.168.0.2; The subnet mask is 24, that is 255.255.255.0; The broadcast address is 192.168.0.255; The name of NIC device is eth0

all computers in the network must set a unique IP address to communicate normally. Because of this unique address, users can select the objects they need from thousands of computers efficiently and conveniently when they operate on networked computers

The IP address is just like our home address. If you want to write to a person, you need to know his or her address so that the postman can deliver the letter. A computer sending information is like a postman. It must know the only "home address" to avoid sending the letter to the wrong person. But our address is expressed in words, the address of the computer is expressed in binary numbers

eth0 is the name set by the system for the network card. If there are al network cards or multiple network cards, there will be names like eth1 and eth2. The name can be set artificially. It is the unique name of the network card in the current computer system
