How does Etz mine

1.

1. about the variability of blockchain

2. eth, if most people agree to modify the chain, that is, variability, then they can modify the blockchain records and contracts

3. etc, blockchain records and contracts can't be modified, that is, they can't be tampered with

4. here are the advantages and disadvantages of the two methods

   The advantage of

5. variability is that people can make timely changes to make the right decisions. Therefore, modifying the specification is more practical than finding loopholes

6. non modifiability means that no matter how smart people are at that time, it is impossible not to make mistakes. Therefore, when problems arise in this scheme, it is best to find and solve the loopholes through the existing legal framework

7. differences in development

8. eth, whether it is intentionally arranged or since its birth, the core decisions of blockchain are made by Ethereum foundation with the participation of the community and most of them are developed by it

9. etc, the decision-making of blockchain is mainly decided by the feedback of three loose, collaborative teams with community participation

10. in any case, anyone can put forward improvement suggestions for the two kinds of blockchains. This is the benefit of open source, and it is also very common. You will find that developers of the two chains communicate with each other through GitHub and reddit. I hope to improve the frequency of communication in order to achieve the common goal

11. about compatibility

12. at present, the two kinds of blockchains are compatible with each other. Contracts or applications written by eth can be applied on etc, and vice versa

13. eth, focusing on ewasm, is committed to providing a platform for more and more developers, while the issue of contract security is secondary, such as viper

14. etc focuses on making developers create more secure contracts, such as viper, iohk research, at the cost of consuming the number of potential developers

15. it's obvious that both chains can accept each other, regardless of whether their wishes are the same or not. My view is that the number of developers is not necessarily related to the quality of the proct

16. about the transaction speed

17. eth, the average is 25 seconds, which will be shortened after upgrading

18. etc, with an average time of 14 seconds, maintained at 10-14 seconds after upgrade, according to ecip-1010 and ecip-1036 protocols

19. about the block capacity

20. eth, with the daily trading volume of eth graally reaching 5 million, the block capacity is graally saturated. This situation is similar to the recent transaction cost of bitcoin. This problem can be solved by expanding the block capacity by increasing the default fuel limit

21. ETC­， At present, there is still a lot of room for block capacity. As more and more people accept etc, the block capacity will also increase, just like eth

22. about community

23. eth, mainly discuss on reddit

24. etc, mainly discuss on slack

25. about monetary policy

26. eth, the planned supply is growing steadily, resulting in an average inflation of 3% in eth blockchain in its life cycle

27. etc, before 2025, inflation will reach 3%, and then the total supply will reach 200 million etc, and then there will be deflation

    As for the regional distribution of trading volume, China accounts for 20%, South Korea 25% and the United States 25%
    In etc, China accounts for 50%, South Korea 25% and the United States 10%
    About securities, at present, investors do not have the option to trade securities. Recently, one of eth's ETFs, trading open-end index funds, was denied by the regulators

28. etc owns etc trading trust, which allows investors to own etc instead of the asset itself

2. The simple point is to use the tools in the optimization master to test
the advanced point is to use 3dmark2005

and then look at the memory and CPU. The second-hand computer's memory is better than 256M,
many friends can't be sure how their computer performance is after they install a new computer. How should I test the performance of my love machine? Friends who often read computer evaluation articles may know that many friends evaluate their computers by running a large number of evaluation software. But it's not necessarily for all friends. Many friends may have a headache in the face of various data, and they may not understand what kind of performance these data represent. What's more, we don't necessarily have such complete testing software on hand. Isn't there a simpler way to test it? Yes

in fact, the simplest test method is to let the computer run our commonly used software to check whether there is any problem with the computer, and simply judge whether the computer performance meets the requirements. Generally speaking, tests can be divided into several categories: game test, movie playing test, image processing test, file test, compression test, network performance test. These tests basically include the overall test of computer performance

game performance test. Few friends who buy computers don't play games, and the game can be said to be a comprehensive test of computer performance, including the test of CPU, memory, graphics card, motherboard, display, CD-ROM drive, keyboard and mouse, sound card, speaker, etc. So, the first thing a computer should do is test the game. We can choose several common games to test our PC. For example: top speed car, Tomb Raider, quake, CS, unreal arena, Warcraft. You don't have to try all these games. You can choose some of them to test the performance of your computer. Friends with higher computer configuration can choose a higher version of the game to test, while friends with lower computer configuration can choose a lower version of the game to test. The test should pay attention to the game installation speed, the game running speed, the game picture quality, the game fluency, the game sound quality and so on. You can change the display settings, graphics card settings, BIOS settings, system settings, game settings to feel the different performance of the computer under different settings. For example, change the brightness and contrast of the display, change the resolution of the game, change the frequency of the graphics card, change the memory delay, change the CPU frequency, change the hardware acceleration ratio of the system, change the system cache settings, and so on. You should pay attention to that before the test, you'd better install all the patches, change the settings, and change the settings back (or to the best state) after the test. Qualified friends can compare with computers with similar configuration, and I believe I can feel the performance of my favorite computer
next, consider playing a movie to test your computer. It is recommended to choose the commonly used player and familiar movie, so that you may not need to compare with other computers to see the "advantages" of your favorite computer. At this time, we should pay attention to whether the playback is abnormal, the brightness of the picture, the change of the picture after adjusting the brightness of the display, the clarity of the movie picture and so on

next, we can consider testing the image processing ability of the computer. The author recommends using common graphics processing software to test, such as Photoshop, fireworks, AutoCAD, 3D Max and so on. You can try to open multiple picture files, change pictures or edit pictures to test the image processing speed and observe the image quality

the test of ing files is relatively simple. You should try to choose a larger file . You can choose to VCD or DVD. Compression test can choose our commonly used winzip or WinRAR to compress larger files. You can also test the computer by compressing CD and VCD, and choose our commonly used super software to test. The above tests focus on speed

network performance test is relatively simple, mainly to check whether the network can connect normally and whether the connection speed is normal

in addition to the above aspects, you can also run some common test software to see the computer score. For example, 3dmark2001se, 3dmark03, pcmark04, etc. Then you can compare it with the online reference score to get the evaluation of the computer.
