Number of Ethereum communities

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

3. 1. What is the ether classic<

etc (Ethereum Classic) is a bifurcated currency that Ethereum hard bifurcates after 1920000 blocks, and its function is very similar to Ethereum. Etc adheres to the concept of decentralization and supports the consensus mechanism of blockchain guarantee. Etc firmly believes that once the blockchain starts to run, its development direction will not be controlled by any central team, but will be determined by the consensus of the people participating in the whole network and the consensus of the computing power of the whole network

the Ethereum blockchain hard branching in July 2016 aims to transfer the Dao funds stolen by hackers to an account controlled by investors, and let the old transaction records be forgotten by history. Most Ethereum developers are involved in the reversal, as are exchanges, startups and other members of the ecosystem. A few days later, the project returned to normal. But not everyone wants to forget the old record. As a result, a small number of miners continued to use the original blockchain as a protest. They described the hard fork as a capital withdrawal for the abandoned project of the Dao. So Ethereum classic (etc) was born

2. Detailed parameters

Chinese Name: Ethereum classic English Name: Ethereum classic English abbreviation: etc

developer: Ethereum Classic team core algorithm: ethash consensus proof: POW

release date: 2016 / 7 / 20 block time: About 15-17 seconds / block

total currency: fixed at 210 million, up to 230 million, Every 5 million blocks decelerate by 20%, and the first proction rection is expected to be in December 2017

main features: independent cryptocurrency

4.

The price of Eth and other virtual currencies is determined by the following aspects: 1. Frequency of use; 2. Actual use; 3. Number of participants

as for how much room to go up, the current price of Ethereum is about 6600. Recently, e to the frequent use of Ethereum private placement, Ethereum has risen to more than 10000. Ethereum is a smart contract, and there are countless tokens developed based on Ethereum. Therefore, as the underlying public chain of smart contract, its prospect changes with the popularity of blockchain, However, some time ago, the disadvantages of Ethereum were exposed. The main chain was congested and the handling fees were extremely expensive. The development of Ethereum was close to the bottleneck. Therefore, the room for its growth was whether the developers could improve the main chain environment according to the disadvantages. As for the number of participants, it was not a big problem now. Pay more attention to the current development progress of the developers and focus on doing things, There is a bright future ahead

at present, the websites that can trade Ethereum include: btctrade international station, Huo coin, coin an, etc.

5. Different communities belong to community assets, and forums belong to different local attributes of communication

6. In fact, most trading platforms support eth Ethereum trading

7. The bifurcation of Ethereum Constantinople is about to begin. Many people are curious about this bifurcation and are not sure whether they need to be prepared in advance
to put it simply: if you are only the holder of eth, you don't need to make any preparation for this upgrade.

9. 🌎 &# 128144; The shock is coming&# 127758;
it took only three years for Ruibo 5 yuan to become 100 million yuan
it takes eight years for bitcoin to change from 300 yuan to 100 million yuan
it took two years for the small ant coin to change from 110000 to 100 million
it took three years for Ethereum to change from 20000 to 100 million
have you seized all these opportunities? If not, then you must seize our Dakar

10. Define target groups, such as blockchain, and strengthen identity. In fact, a community is a group of like-minded people gathering and connecting to maintain the vitality and activity of the community. A community needs a series of activities to gather users, strengthen user relations, and promote the existence of the community. The value of the community lies in its operation. Operation needs professional execution team, content proction, activity planning, new media operation and customer service. What's more, we should do something that resonates, gather people's popularity and resonance, let everyone in the community mutual benefit, and do incentive welfare
together with WeChat users, QQ group, micro-blog, official account, network promotion, etc., we will gather users with common concerns. For example, we set up chain link groups in QQ group, bitcoin, Ethernet similar, let people who find common sense of belonging join in, and promote keywords in the network.
