Profit of Ethereum node server

1. Ethereum is the largest and most widely used public chain after bitcoin, also known as blockchain 2.0. It is an open source public blockchain platform with smart contract function. Its goal is to build a new generation of decentralized Internet application platform
bitcoin has been graally recognized by the market as digital gold, and bitcoin has also been graally recognized as personal private property by global law, which is protected by law. As the second largest cryptocurrency in the market value, Ethereum and bitcoin have no history of eliminating good money from bad money, but Ethereum's money, which is similar to the silver standard, has also been widely recognized
when Ethereum was launched in 2014, it was only 2 yuan. In early 2018, the highest price rose to 10000 yuan. Now, after the price fell, the bull market will restart. With the launch of Ethereum 2.0 system, the peak of exceeding 10000 yuan is just around the corner
the investment method is very simple. Search "tacu Asian Stock Exchange". After registering and logging in, follow the prompts to invest in bitcoin. Now you can also give free digital currency for registration. This is a transaction registered in Thailand. The Thai royal family has a share in the transaction, and the credit is guaranteed. I registered on this platform and sent 1000 coins, with a maximum value of more than 10000 yuan. If you have other problems you don't understand, you can solve them by contacting customer service directly.

2. First of all, you need to understand what Ethereum is. Ethereum is a platform and a programming language that enables developers to build and release the next generation of distributed applications. Ethereum can be used to program, distribute, guarantee and trade anything: voting, domain names, financial exchanges, crowdfunding, corporate governance, contracts and most agreements, intellectual property, and smart assets that benefit from hardware integration. Eth is a kind of digital token of Ethereum. Developers need to pay eth to support the application.

3. Although the domestic exchanges were completely shut down in 2007, overseas exchanges are still open to domestic investors, such as the domain kingdom. Ethereum is the world's second largest virtual currency by market value, second only to bitcoin. Although the price of Ethereum has been falling in recent days, it can still be invested because it can also buy profits when the market falls.

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. I plan to start a series to talk about architecture. My previous experience is mainly in the area of Internet architecture. Recently, I am sorting out and analyzing the architecture of bitcoin, Ethereum and EOS, so I am going to write a series of articles to talk about the understanding of Internet architecture and blockchain architecture. It will be divided into four articles: 1. Internet proct architecture, 2. Bitcoin architecture analysis, 3. Ethereum architecture analysis, 4. EOS architecture analysis
there is no central server in Ethereum. Instead, there are many equal nodes connected by P2P protocol, which store all the data in many nodes. When a user initiates a transaction, the transaction will be broadcast out through P2P protocol. The miner node verifies, packages and further broadcasts the transaction to the whole network. After confirmation in the blockchain, the operation is considered to be unchangeable
in the articles on blockchain on the Internet, the two words distributed and decentralized are mentioned, sometimes slightly different, sometimes mixed. The author thinks that if we want to distinguish accurately, the distributed system emphasizes that multiple components work together by sending messages, and the decentralized system emphasizes that there is no central node to control the operation of the whole system. Therefore, we think that Ethereum is both decentralized and distributed, or running a decentralized program on a distributed platform.

8. If halving leads to greater difficulty in mining, then the reward will surely be higher. Because bitcoin is graally scarce, it will rise. At present, bitcoin on bitoffer is US $9300. If it is halved and doubled, the later theoretical price is US $18600. Let's give it a discount. How can it be US $15000

9. Bitcoin needs mining machine for a long time, but VPS is not powerful.
if it's a transaction, it's OK to use VPS for transit.
it's better not to touch counterfeit money
