1. " It's a long winter. According to the current market situation, there is a high probability that it will fall in 2019. It's almost impossible to break out. However, the instry will continue to move forward, and the decentralized exchange will continue to move forward. This is the trend of the future
one of the core advantages of decentralized trading is to avoid any assets being entrusted. You have absolute ownership and control over your own assets. The possibility of asset theft is extremely low, which greatly reces the trust cost of users on the exchange
from another point of view, with the implementation of blockchain applications, we have more and more digital assets at the same time, and we need to pay different tokens when using services. In this case, cross currency trading will become more and more frequent, and the process of realizing this transaction needs to rely on the mechanism of decentralized exchange
therefore, the decentralized exchange will have a bright future. Among all the decentralized exchanges, whaleex is my favorite. It not only has fast trading speed, but also does a very good job in security performance. Among all the exchanges at present, I think it is the best one. I don't have to worry about stealing or losing money when I put money in it. Their smart contracts are through security audit, and they will also support cross chain and legal currency OTC. If they grow up in this bear market, they will be a giant. I am very optimistic about its prospects& quot;

2. Compared with centralized trading platform, what are the advantages and disadvantages of decentralized trading platform
since 2013, many decentralized trading platforms have emerged. Different from the centralized trading platform, the decentralized trading platform does not need to register an account, and can participate in the transaction by using the personal digital asset account
secondly, every transaction of the decentralized trading platform is carried out through the blockchain, and it needs to wait for the confirmation of the blockchain before the transaction is successful. At the same time, the decentralized trading platform is not responsible for keeping users' assets and private key information. On the one hand, it avoids the moral hazard of the trading platform, on the other hand, it requires you to keep your private key well
e to the low liquidity and slow transaction processing of decentralized trading platforms, the total transaction volume only accounts for 0.03% of the global total transaction volume of digital assets. At present, the tokens of airswap, kyber, 0x and omisego can be traded on huobi.pro.

3. Part of the code is open source, the core code is not open source
or when it is open source, there is a bug in 10 lines
the development of likelib public chain has the following stages: condensation stage, solid foundation (in the next 1-2 years), improvement of technical design documents, completion of basic mole code development, online main chain, continuous improvement of intelligent contract, multi chain parallel, cross chain consensus and other early functions, improvement of main chain, side face and surrounding ecology, including blockchain browser, light wallet and mobile wallet, Smart contract, virtual machine, compiler, development tools, multi language adaptation, etc. Establish, develop and improve open source community, start and promote more application access
in the integration stage, it will grow steadily (in the next 3-5 years), complete the implantation of more consensus moles, realize the self evolution of network, storage and other moles (support EB level data storage), form a standard technical solution system for docking applications in various instries, and explore a new ecosystem combining blockchain with big data, artificial intelligence and other fields. Form a mature open source community and establish application side chain on a large scale
in the sublimation stage, a technology platform integrating blockchain, big data and artificial intelligence will be established everywhere (in the next five years) to provide comprehensive solutions for the proction and operation needs of instry, agriculture and commerce. Form an open source community with the integration of blockchain, big data and artificial intelligence, and provide a comprehensive value docking and cooperation platform.

4. One of the three conditions for large-scale implementation of blockchain applications is blockchain 3.0 technology, which can improve the performance, ease of use, operability and scalability of blockchain, and involves new technologies such as side chain, sub chain, cross chain, layering, fragmentation and zoning. According to Xiao Feng's observation, most of these technologies will mature in 2019, and the main network will go online. The launch of these new technologies is the premise of large-scale commercial application of blockchain. So from a technical point of view, after 2019, the large-scale commercial application of blockchain can be expected
the second is that only mature technology is not enough. In order to realize a large number of DAPP and commercial applications on the blockchain, we must be prepared on one hand: that is, the digital currency that can be used as payment tool, exchange medium, value measure and value storage. Xiao Feng said that everyone thinks that bitcoin is a payment system, but the real bitcoin can not meet our demand for payment because its currency value fluctuates too much
for example, he said that a mall sold a bottle of water and accepted bitcoin payment. When he got up the next morning, he found that 20% of the value was gone. So it can't be accepted. After the Japanese parliament made it clear that bitcoin could be used as a payment tool, some Japanese businesses announced that they would accept bitcoin payment. But later found that it caused a lot of trouble for the stability of the company's balance sheet. Your balance sheet is unstable, up or down. This not only affects the value of the things sold, but also affects the credit evaluation of enterprises and the services provided by banks to companies
the third condition is the construction of laws and regulations and supervision system. The digital economy on the blockchain must obtain legal protection and comply with the law. Xiao Feng stressed that there can be no decentralization in this regard
the differences between blockchain and Internet are discussed. He believes that the core difference between the two is that the Internet is a centralized trust mechanism, while the blockchain is a decentralized trust mechanism, and there is no need to trust a third party
the second core difference between the Internet and blockchain is the incentive mechanism, not the digital currency or the ability to issue currency. Economics has been discussing incentive incompatibility. Under the company system and on the Internet, the incompatibility of incentive mechanism has not been solved. However, in the decentralized blockchain, the blockchain achieves complete incentive compatibility. Without shareholders, board of directors and employees, the conflicts of interest between these roles will not happen again.

5. I have been in touch with Qian'an for a long time. In terms of ability, Qian'an is still very good. Its advantage is that it is the largest digital asset transaction in the world, and the best trading volume in 24 hours has exceeded US $10 billion. It's amazing to achieve such a performance in the instry.
6. How much does it cost to register a company in Shanghai? Many entrepreneurs will probably ask this question. In the era of national entrepreneurship, most people will choose to register the company after they have a project. However, there are two practical problems in front of Shanghai registered company:
first, if there is not much start-up capital in hand, how to raise funds to set up a company with a registered capital of 1 million yuan
Second, we are going to start business at home at the beginning, but we can't complete the instrial and commercial registration of family residence. What should we do< In fact, since March 1, 2014, the state has begun to adjust its policies and implement the system of subscription of registered capital. Even if there is no start-up capital, other methods can be used to register the company. In the new policy, the restrictions on the way, time limit and amount of capital contribution are cancelled. The purpose of the state's move is to encourage entrepreneurship. Even if you don't have any money, you can easily register a company with 1 million yuan in this way. In the future, when you make money, you can supplement the registered capital
What are the fees for registering a company in Shanghai, regardless of the registered capital? Zhihao has sorted out for you the expenses of business registration, seal engraving and tax registration certificate in the process of company registration, as well as the expenses of subsequent business tax declaration, taxpayer and registered address of the company
I. business registration fees. In the national policy, business registration does not need to spend money, free of charge
2. The cost of official seal engraving. A very important step to complete the instrial and commercial registration is to obtain the official seal. The cost of carving the official seal is 50 yuan / set, which is a necessary cost< Third, the cost of tax registration certificate. The fee is free< 4. Fees for Instry license and food hygiene license. If the company needs to apply for these certificates, there may be corresponding expenses< 5. The bank opens the basic account of the company. For bank account opening, the fee charged by each company may vary to a certain extent. The general fee is more than 500 yuan< 6. The cost of purchasing invoice. The company needs to buy tax cards, special printers, billing software and so on. The total cost is about 2000-3000 yuan< 7. If you need to apply for general taxpayer qualification and issue VAT invoice, the cost will be increased. If an enterprise is engaged in import and export trade, there are administrative charges when it goes through the import and export filing proceres, and the cost is about 2000 yuan.
8. If it is entrusted to an agent company, the cost of registering a million companies in Shanghai is not much, but in the process of registering a company, there may be a lot of cumbersome affairs to deal with, In this case, in fact, looking for an agent to complete the registration can save more time and energy. The total agent fee is about 500 yuan
simply speaking, the process of business registration in Shanghai is as follows:
check the name - register online - hand in the business establishment information - get the business license - engrave the seal - do the organization code certificate - do the tax registration certificate - open the basic account (taxpayer)
the detailed steps and cycle are as follows:
1. To approve a company name, it is better to submit 3-5 company names in the preferred order at a time to prevent plicate names. If it is submitted again, the approval time will be longer. The name of the company requires the company name, shareholder name, ID number and capital contribution ratio. 1-3 days
2. After the name is approved, fill in all the delivery materials, make an appointment, and submit the documents to the Administration for Instry and commerce; 7 days
3 and 7 days later, after obtaining the business license, we will handle the tax, code and stamp. 7 days to complete the documents

7. Seedlings, then, according to the size of each plant 0.8-20 pieces of ocean, dry (commercial medicinal materials), 420 / kg!
8. Polkadot is the representative of the existing cross chain technology, which pays more attention to the cross chain infrastructure; The emerging fusion emphasizes the realization of asset smart contract, while ether universe emphasizes high-performance, decentralized cross chain infrastructure, and access to a variety of cross chain applications, focusing on commercial landing.
9. The cross chain relay layer realizes the basic logic of asset trusteeship and inter chain interaction through smart contract, and the public trust node realizes the input of out of chain state through oracle; Through the relay layer, we can realize the trusted interaction between gxchain, parallel chain, application chain, decentralized business alliance and other homogeneous and heterogeneous chains.
