The replacement of Ethereum

2.

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. Really, Ethereum itself is a kind of virtual digital currency. When trading, it is a string of numbers. How can there be a fake? ZB trading has been going on for many years

4. In fact, the rise and fall of digital currency is a normal situation. The key is to see whether you are optimistic about its long-term value. Relatively speaking, if the long-term value is worth investing in, then the short-term decline can be ignored. At the same time, if you don't know much about digital currency users, it is recommended to choose a reliable and good platform for investment. The investment period needs more than six years, Word of mouth should always be good, you can take a look at AEX, fire coin these two, but also more reliable, you can also understand their own network first

5.

Many people think that the reason why bitcoin is valuable is because it is "rare", and if bitcoin is no longer "rare", then it will not have value

this is a misunderstanding. Let's consider a question: what is the essence of all "currencies"

the answer is trust. The biggest reason for the value of the dollar is because of the credibility established for the dollar under the Bretton Woods Agreement, rather than the so-called equivalent exchange with gold (although others say so). The main reason why RMB is valuable is because of the trust system of RMB in China and neighboring countries, rather than the exchange with us dollar reserves (see offshore RMB). This can explain why the currencies of some countries (such as the ruble of Russia, as well as the Zimbabwean currency as you all know) have been greatly devalued, because the government and the current world situation have led to a trust system that does not support the existence of this currency. The so-called economic sanctions and currency speculation are very superficial and superficial reasons

the essence of money is trust

What about bitcoin

bitcoin has no centralized Trust Measurement institution. The value of bitcoin, namely its "credit system", comes from distrust of centralized units. Every country finds that seigniorage is too easy to collect, which leads to the increasingly poor trust between countries. Even the people of all countries do not trust the national currency

and trust, like quality, is conserved. Trust in centralized money decreases, while trust in decentralized money increases naturally

this is the essential reason why the value of bitcoin continues to rise. Therefore, for digital currencies such as bitcoin, there are only two outcomes. Either countries want to understand that they will no longer issue excess currencies, issue additional currencies in a scientific and reasonable way, unify stable exchange rates, and maintain the credit system of centralized currencies, then the value of bitcoin will be infinitely close to zero. Or countries will continue to drink water to quench their thirst, and more frantically use the method of issuing excess currency to collect seigniorage from everyone, then the trust in the centralized currency will be lower and lower, and the total value of bitcoin, a decentralized currency, will be infinitely close to the gross labor value of all the units that do not trust the government and other governments, but need international trade

either the price is crazy or it's worthless

after understanding these, we can answer this question. Will bitcoin be replaced by other digital currencies

swindlers like * * and even the old Wang next door can come and yell, "I spent 10 minutes to change bitcoin's core and create a new digital currency called SBC. Come and join my ICO and pay me seigniorage ~". So, if this happens, will you immediately choose to use Lao Wang's SBC next door

the answer is that some speculators will participate, but the market will not. The reason is very simple, the new cryptocurrency has not been recognized by the market, the application has not been proced, this kind of currency has no way to exchange for means of proction. Then this kind of currency is not money, but a virtual commodity for speculation. In other words, even if old Wang ICO next door has an SBC, no one will choose this kind of currency except those speculators who have no brains

in the current market, there are many other digital currencies, such as Ethereum, EOS, XRP, and so on, which may have technological advantages in some aspects (in fact, BTC has been evolving, and it will also learn from the advanced technologies of other digital currencies that have been successfully proved by the market. LTC and other currencies can be said to be the experimental currencies of BTC's advanced technologies.), There may be more application scenarios than BTC in the future, but they are not likely to challenge the status of BTC. BTC will always be the first consensus in the currency circle, which is the belief of many people. BTC will exist for a long time as the gold in the currency market, not mainly for the circulation of digital currency

7. First of all, we need to be clear that these investment procts are virtual currencies. This requires investors to have more first-hand information and accurate financial sense. In this way, many virtual currencies can be made!

8. There are hundreds of digital currencies on the market. Apart from bitcoin and Ethereum you mentioned, there are also Leyte, ecell, reborn and TEDA coins with good reputation.
