Ethereum adds its own nodes

1. Many institutional investors have begun to pay attention to Ethereum. Ethereum also rose and institutional investors have a lot to do with admission. I think Ethereum will go up. The stock exchange proposed to go to Zhongyuan, which is a seven-year-old stock exchange and has never had any security incidents. Trustworthy.

2. Note that Ethereum is 2.0 now. As of 13:57 on the 4th, the current deposit contract address of Ethereum 2.0 has received 1000098eth, and 31252 addresses have completed the mortgage of 32eth. With the increasing number of mortgage, the annual yield of mortgage will graally decrease. After the mortgage amount reaches 1 million eth, the current annualized yield is about 15.7%. Zhongyuan, a well-known exchange, has taken the lead in opening the mining channel of eth2.0 verification node, and then launched qeth. Users can invest their own eth in verification node mining and exchange qeth to obtain liquidity, and then participate in mining. Compared with the disadvantages of eth2.0, qeth has too many things: the liquidity is guaranteed, the user does not have to bear the technical cost, the threshold of participation does not need 32 eth as low as 0.1eth, the nodes are maintained by the platform, and the income is distributed according to eth2.0.

3. Eth mining mainly uses graphics card to mine. Therefore, you need a PC with the following devices:
graphics card, motherboard, power supply, CPU, memory, hard disk (more than 60g SSD is recommended), extension cable, adapter cable, etc
among them, the graphics card determines the speed of mining, and the motherboard and power supply largely determine the stability of mining machine operation.

4. Yes, but it is better to use overseas servers. In addition, the server configuration should be medium or above.

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

6. How many account addresses can an Ethereum node have at most
A: generally, there is only one account address, otherwise there will be an error! blockchain itself is unique. If there are multiple account addresses on one node, it violates the fundamental principle of blockchain!

7. Go to the crater.
although the place is large,
the mines are relatively concentrated,
it won't let you go around.
moreover,
a vein can be g many times,
that's where it's a little scary

8. There is no problem at all, but relatively speaking, we must buy some reliable ones, because we must pay attention to them.

9. Blockchain technology has a natural advantage in the realization of smart contracts
bitcoin, Ruitai coin, Laite coin, Ethereum and other digital cryptocurrencies all use blockchain technology
blockchain is an important concept of bitcoin, which is essentially a decentralized database. At the same time, as the underlying technology of bitcoin, it is used to verify the validity of its information (anti-counterfeiting) and generate the next block. Blockchain is a series of data blocks generated by cryptography, each of which contains the information of a bitcoin network transaction
