Decentralized forecasting platform

1. Whaleex: it's a decentralized exchange based on EOS. I usually choose it when I trade. The trading depth is good, and the transaction can be completed soon after I register. The best place is the high security. The smart contract passes the security audit and can be used safely
x protocol: a point-to-point open protocol running on Ethereum. The protocol aims to become a general open standard, as a basic mole that can be combined with other protocols to drive more and more complex blockchain applications. However, Ethereum is famous for its congestion, so its current situation is not very good
loopring
Road printing protocol: decentralized transaction protocol of class X. The on chain smart contract is responsible for asset custody, matching and transaction, and the off chain smart contract is responsible for order matching. It has an on chain trading loop matching technology, which encourages the exchange to match the transaction path with the maximum discount, so as to save transaction costs for users and make the exchange profitable at the same time. But on the other hand, it also increases the complexity of smart contract and the execution cost of Ethereum transaction, and the effect in practical application remains to be seen
there are also kyber, idex, bitstocks, etc. decentralized exchanges are the trend in the future, so there are still quite a few in the market. But comparatively speaking, I still think whaleex is the most reliable.

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. The so-called Internet platform is to develop and utilize the information resources of the Internet. I personally understand that the instry should be concentrated together and one key solution should be taken to save the middle cumbersome steps. The 16 year Internet plus summit, which is the latest Internet plus summit held in Beijing in 16, will be held in the 16 month of. This will further promote the development of Internet +. To promote the integration of "Internet plus" with government, people's livelihood and all walks of life, we can learn about this area.

4. I have been playing currency for many years, and I have used many trading platforms. I think the best one to use is gotc decentralized trading platform. First of all, this platform is a truly decentralized trading platform. On this platform, the power to initiate and agree transactions, as well as the power to quote, are in the hands of users, and the platform has no right to interfere or participate in the reconciliation. It's very safe and reliable.

5. Defi, a decentralized trading platform, is more reliable. I think it's a professional platform. It's a better platform because it has a wide range of radiation

6. Take gotc for example. All records can be queried through blocks, which is true and reliable
the order is linked in seconds, and the transaction is completed in an average of five minutes; Only 0.2% will be charged to platform merchants.

7. First, the goal of refined operation. For example, if your proct is just a tool, I'm afraid it can't be said that there are too many refined operations. Generally, it's enough to do a good job in routine user behavior analysis, and then cooperate with user qualitative research to guide proct design; If it is a content-based proct, or a proct with both function and content, it really needs to be considered. 2. Design statistical framework suppose that users will frequently interact and use functions on your app, and browse or generate content at the same time, so you need to design your statistical framework well while designing procts. 2、 Data collection first lists the data items you need, then evaluates which parts need to be reported by app and which parts can be counted in the background, and then adds them on the front and back platforms. Generally speaking, the collected data reported by app must be carefully checked and tested before release, because once the version is released and the data collection goes wrong, not only the previous efforts are wasted, but also a lot of dirty data will be brought. At the same time, the running efficiency of the client may be reced, and the gain is not worth the loss. 2. After data collation and data collection, all kinds of original data need to be processed into intuitive and visible data needed by proct managers. Here, we need to do some basic data logical association and display, so we won't repeat it. 3. Data analysis according to the statistical framework designed at the beginning, you can clearly see the data you need. Of course, the above is just a more basic analysis. If you get these data, you can analyze that users who use a function also like B function. The two are closely related. Can you consider more integration or interface adjustment in front-end design; For example, by analyzing the click stream, what are the paths for most users to visit or use the app, and do they hide the core functions too deeply? For another example, we can analyze different user attributes, such as male users and female users. Do they have significant differences in user behavior? wait. There is a big gap between the data analysis methods and models of different procts, which cannot be explained at once. So the above are more examples. 3、 Some principles need to be noted: 1. The data itself is objective, but the data interpreted must be subjective. The same data analyzed by different people is likely to draw completely opposite conclusions, so we must not analyze it with opinions in advance (for example, if we have hypotheses, we can use the data to demonstrate them); 2. Data collection by app must be of low priority. It can't affect proct performance and user experience because of data collection, and it can't collect user's privacy data (although many domestic apps don't do this); 3. Data is not omnipotent. You should trust your own judgment.

8. If it is truly decentralized, there will be only one dotc.pro, and the others are not truly decentralized. Dotc.pro, from transaction to transfer currency, is settled on the smart contract chain, not on other platforms

9. Specifically, in short, the service provided by the OTC area is similar to the digital currency Taobao. Users can freely display their digital currency assets on the platform, and conct point-to-point legal currency trading with people from all over the world. The platform does not participate in trading and mixing, and the whole process is supported by EOS blockchain technology. Gotc is OK

10. There are many such systems, and there are many such projects in the chain

for example, the underlying technology of the decentralized quiz application platform based on wikichain is blockchain technology. In 2017, blockchain is no longer just a concept term, but is slowly landing to provide more convenient and advanced services for the public. Blockchain with its decentralized, distributed accounting, tamper proof and other characteristics has quickly gained public attention. It is well known that the role of blockchain in "trust" is just like that of Internet in information. The most scarce element of the Internet is the "credit Protocol" to determine whether each transaction is approved and effective. Blockchain technology can provide the basis for solving this problem and optimize the way people deal with trust, security and privacy issues

based on its ability to improve transparency and protect privacy, blockchain technology can lead people to a fairer, more efficient and more accessible global financial system, bringing great changes to traditional manufacturing instry, financial instry, government departments and even human society

based on the technical characteristics and advantages of blockchain, the wikichain team has developed a decentralized application platform for guessing - wikichain.
