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. Remember that in zamby community, there are courses based on erc20 protocol in zamby school section

4. Let's talk about the social or economic significance of blockchain. In fact, many of the previous technologies were devoted to "proctivity". For example, artificial intelligence is a kind of progress in proctivity. The blockchain, which has greatly improved the proction relations, is committed to the proction relations. So why do you say that
because the so-called proction relationship is actually how to do business between people and business partners. And these things, originally, are in the cognitive process between people, and there is no special program to program or quantify it
for example, if you and I are good friends now, we can do business. If someone stirs up our relationship and we are not good friends, we will not do business. Even if we can make money in business, we will not do business because there is no trust between us
as for blockchain, it is actually because the data is authenticated by all nodes and backed up at the same time, so my data is as real as possible and can't be tampered with. In this case, if you believe my data, you can make a program on this basis, and then use the data to make what kind of business contract, what kind of service, what kind of service, and what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, etc This "proction relationship" of commercial cooperation is programmed. In this way, we believe in the data and the program compiled by the algorithm. Because you believe in the data and the program, you can develop all kinds of apps in the program. These apps are the proction relations and what business to do. This is: blockchain is actually a reconstruction of "proction relationship".

5. Block chain is not omnipotent, there is not much at present landing. You don't want to hook up with supermarkets. I can only think that Alipay and WeChat are now paying for them, and the only possible advantage of using block chain means is that there is no need for third party agencies to guarantee (Alibaba and Tencent) to save costs. And Alibaba and Tencent have the risk of running away (although it seems almost impossible at present), and they won't worry about program Defection with blockchain

6. 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.

7. Understand the development history of the next block chain, and then focus on the company's four technology backgrounds, and also update the official account to see the daily updates.

8. You can only dig it. If you can't, you can only buy it by auction house. It's a little less than 10 in 2 hours. Where did you dig it? You can go to Huanxing mountain and xilisus. The output is still good. You can also find the transformation master's Alchemy to transform AOJIN ingot, which can be critical hit.

9. There is no specific measure. But we can choose from several aspects:
1 those who have many excellent tutors
2 those who have cultivated many excellent students
3 who only do training, but not others
4 who have done it for a long time.
