The gap between Ethereum and Ethereum classics

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. 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

3.

The idea of Ethereum was born in 2013. Vitalik buterin ˙ When he was a programmer in the bitcoin community, he suggested to the core developers of bitcoin to develop a language for application developers to facilitate the development of various applications. Bitcoin core developers disagree. So God V decided to develop a new platform for this purpose

V God wrote the white paper of etheric currency in 2013, in which he explained the goal of building a decentralized program. In 2014, we got development funds through crowdfunding, so we developed the Ethernet system< (better digital currency trading platform "currency exchange")

since its birth, it has carried out four hard bifurcations so far

for the first time, in order to adjust the difficulty

released a stable version of "homeland" for the second time

for the fourth time, in order to prevent DDoS and rece weight

there is only the third hard fork, because of the hacker attack, and forced to fork. This is the Dao event

On July 30, 2015, v-god and Ethereum Foundation created the first smart contract platform and designed the Dao Ethereum contract

on April 30, 2016, the Dao smart contract was officially deployed, and the world's largest crowdfunding was completed, reaching an amazing $150 million As an aside, the biggest crowdfunding event in time is EOS crowdfunding, which has reached an even more amazing $5 billion!)

on June 17, 2016, the Dao was attacked by hackers, who stole about 50 million US dollars of Ethernet currency, and the price also plummeted from US $20 to US $15, causing great harm to Ethereum. In order to recover the loss of investors, the community finally decided to hard fork

therefore, on July 20, 2016, at the block height of 1920000, the hard branching was successful, and the new chain is called Ethereum eth, while the original chain is now Ethereum classic etc

4. Ethereum is a kind of virtual currency, fire money network is operating virtual currency, also operating Ethereum, this is the relationship.

5. It can be understood that the number of people who support etc is far less than eth, which can be seen from the computational power of mining. If there are many people who support it, the price will be high. At the extreme, an e-coin supported by only a few people is likely to be the same as the one you don't have
central service contract number

6.

The extension of the chain of etc was unexpected by the Ethereum community at that time. When 90% of the computing power was switched to the new chain eth, Ethereum classic with 10% of the computing power appeared in the Ethereum community. This 10% of the computing power is still reported in the short chain, until P network suddenly launched a digital asset called etc, and the token of Ethereum classic was officially born. At that time, the online P network of etc once caused the threat of replay attack. It was predicted that if etc could not solve this problem, etc, a short chain abandoned by most Ethereum communities, would not last. However, etc is still running today< a better digital currency trading platform "currency exchange"

compared with eth, led by vitalik, a computer genius and blockchain star, etc's development team is too quiet. In today's blockchain field, Ethereum has become the second largest cryptocurrency after bitcoin in terms of market value. At the same time, community members are all over the world. According to statistics, among the 100 blockchain projects, 94 are based on Ethereum platform. Such brilliant achievements, in addition to Ethereum development team's superb technology, of course, there is no lack of fierce marketing. Compared with other teams, God V's blessing is originally a big IP, although Ethereum has grown into the second largest cryptocurrency. Today's V God will still hold meetings all over the world, marketing itself as well as eth

on the other hand, etc has been lukewarm for many years. With the continuous development of the blockchain instry, etc, as an old currency, is about to be submerged in the long history. Is it true that, as the instry says, etc and dogcoin are guerrillas? Looking back on the development history of etc in recent years, in 2016, Ethereum classic (etc) was born in the Dao event, which was maintained by a new development team. P network is the first online exchange of etc. with the addition of more and more computing power, the trading volume of etc has graally increased

7. Bitcoin, which is well known to the public, is the classic of ether. You can know that Ethernet classic has done some homework. It is a blockchain + smart contract platform, and many dapps are developed based on it. Function is similar to our mobile phone system, is the underlying technology, based on this technology can develop many applications and procts, drive the development of the whole instry.

8. Next to level 1 training area (you can see a small green dot on the small map, that's it)

9. Ethereum and Ethereum classic are the forks of a chain, but now Ethereum is the main chain, and these two kinds of coins are very common on the exchange platform.
