Ethereum is listed as a security
-
about the variability of blockchain
-
eth, if most people agree to modify the chain, that is, variability, then they can modify the blockchain records and contracts
-
etc, blockchain records and contracts can't be modified, that is, they can't be tampered with
-
here are the advantages and disadvantages of the two methods
The advantage of -
variability is that people can make timely changes to make the right decisions. Therefore, modifying the specification is more practical than finding loopholes
-
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
-
differences in development
-
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
-
etc, the decision-making of blockchain is mainly decided by the feedback of three loose, collaborative teams with community participation
-
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
-
about compatibility
-
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
-
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
-
etc focuses on making developers create more secure contracts, such as viper, iohk research, at the cost of consuming the number of potential developers
-
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
-
about the transaction speed
-
eth, the average is 25 seconds, which will be shortened after upgrading
-
etc, with an average time of 14 seconds, maintained at 10-14 seconds after upgrade, according to ecip-1010 and ecip-1036 protocols
-
about the block capacity
-
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
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
-
about community
-
eth, mainly discuss on reddit
-
etc, mainly discuss on slack
-
about monetary policy
-
eth, the planned supply is growing steadily, resulting in an average inflation of 3% in eth blockchain in its life cycle
-
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 -
etc owns etc trading trust, which allows investors to own etc instead of the asset itself
Ethereum is a cryptocurrency whose market value is only lower than that of bitcoin. The emergence of Ethereum also makes up for the lack of scalability of bitcoin. After five years of development, Ethereum has accumulated a large number of fans. Ethereum's concise functional application highlights its own advantages, but Ethereum, which has been developing smoothly, has encountered a "blow", In an interview, SEC Chairman Jack Leighton made it clear that Ethereum was a security, which caused an uproar and led to a crisis of trust in Ethereum
some days ago, people have been worried that once Ethereum is identified as a security, most Ethereum transactions will be banned. Once Ethereum trading stops in the U.S. market for some reason, its currency price will plunge, and other Ethereum related cryptocurrencies will avalanche one after another, or even withdraw from trading. The blow to the coin ring is unimaginable
If Ethereum is really a security, the consequences will be unimaginable. After all, Ethereum has a very small position in the currency circle. Most people have Ethereum in their hands, which may make the Ethereum in the hands of investors depreciate significantly, which will bring a disastrous blow to the currency circle. Whether Ethereum can survive the disaster will make the exchange and investors sweat. For more details, please clickthe broker disclosed that the simulation test will launch both call and put options, and the contract units are divided into three levels according to the stock price. For indivial shares of less than 20 yuan per share (inclusive), each contract corresponds to 10000 shares; Each share of 20-100 yuan corresponds to 5000 shares, and each contract of more than 100 yuan corresponds to 1000 shares. Based on this calculation, the price of each stock option contract ring the simulation test is about 100000 to 200000. The option fee is 2% of the contract price
the maturity months of indivial stock options will be divided into four stages: current month, next month, next quarter and every other quarter. The way of performance is European style, that is, the position must be closed at the expiration time of the option
the Shanghai Stock Exchange has previously published the "options real simulated trading business plan" and "options real simulated trading settlement business plan" through its website, which shows that the trading time of indivial stock options is from 9:15 to 9:25, 9:30 to 11:30 and 13:00 to 15:00 on each trading day. Among them, 9:15 to 9:25 is the opening call auction time, which ends randomly in three minutes between 9:22 and 9:25, and the rest is continuous bidding time. The minimum change unit of the declared price of the contract is RMB 0.001. The last trading day of the option contract is the fourth Wednesday of the expiration month< According to the known indivial stock option contract scheme, the amount of indivial stock option is relatively large, which is not suitable for indivial investors to speculate. It is more suitable for institutional investors to lock in the stock position risk and hedge the market fluctuation.
