1. Please specify your server parameters and desktop workstation parameters

the server has strict requirements such as fast throughput of large amount of data, super stability and long-time operation. The main goal of server CPU is to achieve the above parameters

the main purpose of desktop workstation is the efficient processing capacity of single task

the design concepts and uses of the two CPUs are different, because it is difficult to compare without your specific parameters. For a simple example, the ability to run a program is not necessarily weaker than that of the server CPU, but the characteristic of the server CPU is that it may be able to run 50 identical tasks to maintain the efficiency level of a single task.

The authenticity of foreign exchange platform can be judged by the following conditions:

(1) first of all, foreign exchange trading is subject to the supervision of the host country, so whether it has obtained the permission of the host country is a very important judgment standard. There is no regulation, or licensing regulation is a false foreign exchange trader

(2) to see whether the trading software used in this platform is genuine, if the use of pirated software, then it is a false platform

(3) some clues can be seen from the website domain names used by the platform. For example, the other party says that he is a big British company, but he finds that the domain name of the other party's website is registered in China, which is a problem

(4) a further step is to do field investigation. According to the reports of netizens, they go to the companies to be reported for on-the-spot investigation: they pretend to be investors and have positive contact with these companies to obtain relevant information. Or go to the places where these companies are registered

extended information:

how to select and use foreign exchange trading platform

(1) first of all, we need to check which regulatory agency the platform belongs to, whether the regulatory number is consistent with the name of the agency, the historical complaint record and reputation of the platform, etc. This information can be checked on the website of the regulatory agency. Regular foreign exchange companies should be subject to regulation. They must not choose unregistered dealers or market makers

Secondly, it is very important to find a transparent platform for transaction costs and rece or eliminate hidden costs. Any investor should know the composition of the fee. Note that spread is not the only cost, investors should pay attention to the hidden cost, because each trader may have different costs. What investors need is dealers with transparent fees

3. Public chain
1, neutral, open and decentralized
2, it can't be changed or cancelled
3, have network effect

when we talk about blockchain, we often hear all kinds of "chains", such as public chain, private chain, alliance chain and side chain. So let Gus give you a simple science popularization of these "chains". Today's "chain world" starts with the public chain
what is public chain

public chain is the abbreviation of public chain. It refers to the blockchain that no matter who can read the transaction data, send the transaction and the transaction can be effectively confirmed, and everyone can participate in the consensus process of the transaction. bitcoin and Ethereum are well-known public chains in the market
we have said before that the essence of blockchain is an account book. In the public chain, everyone can become a node in the system to participate in bookkeeping. Moreover, we can join and leave the blockchain network anytime and anywhere without authorization, which has a high degree of freedom
public chain has many advantages. It is neutral and open, so it can protect users from the influence of developers; All transaction data are open, tamperable and revocable; Moreover, the model without authorization reces the access threshold; Public chain can also achieve large-scale collaboration and sharing through community incentive mechanism
the security of public chain can be maintained by workload proof mechanism POW and rights and interests proof mechanism POS. They usually combine incentive mechanism with digital encryption verification, and follow the general principle: the economic reward everyone can get from it is proportional to the contribution to the consensus process. It is often called "complete decentralization"
problems of public chain

although public chain has many advantages, there are still some problems. For example, the incentive mechanism mentioned above is to encourage all nodes to provide resources and maintain the whole network spontaneously. However, the incentive mechanism like bitcoin has a "verifier's dilemma", that is, the node that has not obtained the bookkeeping right pays the computational effort to verify the transaction without any return

there are also efficiency and safety issues. Take bitcoin as an example. At present, one block is generated every 10 minutes on average, and its POW mechanism is difficult to shorten the block time. POS can shorten the block time relatively, but it is easier to proce bifurcation. Therefore, transactions need to wait for more confirmation before they are considered safe. The test shows that: under the premise of assuming 30% of the computing power each, POS can rece the block time, Ethereum needs 37 block confirmations to reach the security level of bitcoin's 6 block confirmations. It is generally believed that the blocks in bitcoin are secure enough only after six confirmations, which takes about an hour, and can not meet the requirements of most enterprise applications
privacy is also the embarrassment of the public chain system. Due to the characteristics of the public chain itself, the data transmitted and stored are publicly visible, and only through the "pseudo anonymous" way to protect the privacy of both sides of the transaction. For some business scenarios involving a large number of trade secrets and interests, data exposure certainly does not meet the business rules and regulatory requirements
in addition, many public chain projects build platforms first and then find application scenarios, which also brings some challenges to the actual implementation

at present, public chain is regarded as the most promising direction in the field of blockchain, because it conforms to the nature of blockchain and is likely to become the next system level platform
as the underlying platform, the "completely decentralized" feature of public chain may promote the whole society to enter the era of "trusted digital".

4. Futures account opening needs to be handled by regular futures companies. When choosing futures companies, we should mainly consider the following aspects:
first, formality
since online account opening is common nowadays, inexperienced investors are likely to enter the black platform or illegal allocation platform and order platform by mistake, resulting in unnecessary capital loss
1. Before opening an account, log in to the official website of China Securities Regulatory Commission and click on the list of futures companies in the column of regulatory objects. The 149 futures companies listed in the list are all regular and can be selected with confidence
2. Ask the account manager if he supports the opening of futures account in the cloud when opening an account online, and what is the number of the futures company in the cloud. If you can inquire by yourself, you can find that it is normal
3. Don't easily believe that the so-called teachers bring orders or allocate funds. There is no pie in the sky. As long as it is a regular futures company, it will not provide these services. It will only provide the Research Report of the Research Institute for your reference< 2. Qualification rating
China Futures Association will publish the classified evaluation results of futures companies every year, which can be found in the notice on the official website. At present, the rating of futures companies is divided into nine categories: AA, a, BBB, BB, B, CCC, CC, C, D. the highest rating is AA. The highly rated futures companies are rarely subject to regulatory punishment. The compliance supervision is strict, and they are more secure and reliable. The corresponding business scope is wider, and the trading channels and servers are more advanced. Some big companies with the background of state-owned securities companies have better reputation, better service system and high cost performance< Third, trading channel
trading channel determines trading speed, which is an important factor that can not be ignored in futures investment. At present, CTP channel is generally recognized as the best trading channel in futures instry. Large companies with high ratings use CTP channel, and CTP principal is the default after opening an account, Can let the account manager help you apply for CTP two seats, the transaction speed is faster, avoid the loss caused by the slow transaction< 4. Handling fee and margin
at present, the minimum standard of adjustable handling fee is exchange handling fee plus 0.01 yuan, and the minimum standard of adjustable margin is exchange margin plus 0%, which needs to be negotiated with the customer manager in advance, but there are certain capital requirements. If you open an account directly on the official website of the futures company, the initial standard will be default, which is relatively high
generally, the handling fee can apply for the minimum standard without limiting the capital threshold, but the margin ratio needs to be adjusted according to the amount of capital. If the amount of capital is too low, it is not recommended to adjust it too low, because futures have leverage, leverage = 1 / margin ratio, that is to say, the lower the margin ratio, the greater the risk, Futures companies floating part of the margin ratio is also to protect investors.
