What are the decentralized digital currency platforms

2. 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.

3. Some with foreign qualifications will be better, safe and reassuring. At present, there are few in China. Most of them are done in Hong Kong on foreign platforms. You can ask the customer service for more information

4. Generally, the ranking is not reliable for two reasons:

1. Trading volume. Bitwise and Bti reports show that most of the trading volume of the head exchanges is water injection or "washing volume". Domestic exchanges are more serious, and even some exchanges have washing volume as high as 90%. Specifically, I don't guide public opinion and have no interests. You can search by yourself according to the above keywords. There are a lot of news< 2. Advertising strategy of ranking platform. At first glance, you may feel fair and beautiful, but where you don't easily pay attention, the operation of these platforms is very sneaky. For example, if you look at the second page of some ranking platforms (because you only pay attention to the first page, and the second page will not turn), all kinds of ghosts and ghosts are on it, and the weak trading volume is also on it. It's a shop bully. So we still have to clean our eyes

how to choose? Move back the priority of trading volume in your mind, and see what negative comments the exchange has, what controversial currencies are on it, and what functions you want to try. Just sort them out by yourself.

5. It should be reliable.

6. Bitcoin, Leyte coin, dogcoin, Diandian coin, American card coin, bitstock, dark coin, black coin, Ruibo coin, Malaysian coin, Mediterranean coin, Yuanbao coin, Zhaocai coin, sand coin, network gold

7. You will go to the professional big data platform to query

8. It is not recommended to pay attention to it. Digital currency refers to the digitization of currency. Digitization doesn't mean scanning. Just like digital signature, digital signature does not mean scanning your signature into a digital image.

In recent years, a series of policies and measures have been implemented to rece the cost and increase the efficiency of logistics, and remarkable results have been achieved. From 2013 to 2020, the ratio of total social logistics cost to GDP shows a downward trend. From January to September 2020, the ratio of total social logistics cost to GDP in China will drop to 14.4%, which has made a positive contribution to improving the development environment of the real economy and enhancing the operation efficiency of the national economy

however, behind the rapid development of the instry, there are still many problems to be solved, including commodity authenticity, logistics data island (data isolation leads to high interaction cost between enterprises, low efficiency of process collaboration), logistics credit rating (no standard, difficult financing), etc

blockchain technology helps the transformation and upgrading of logistics finance

through blockchain technology, we believe that the pain points of relevant instries can be continuously improved and optimized. For example, it involves commodity traceability, multi-agent collaboration, credit reference, supply chain finance, etc., and integrates "business flow, information flow, capital flow, and logistics". The logistics instry has become an important deployment of the logistics instry

for the future integration development direction, enterprises can combine logistics technology process optimization, logistics package traceability, financial application scenarios based on logistics and supply chain, supply chain and logistics related credit reference needs, rely on blockchain technology and existing logistics network, truly and reliably record and transmit capital flow, logistics and information flow, Optimize the utilization of resources, improve the overall efficiency of the instry, and promote the sustainable development of the logistics instry

through the combination of blockchain and logistics finance application scenarios, in essence, it is through mortgage property and data cross node sharing, and finally, it is to achieve logistics credit rating, so as to obtain financing convenience and interest rate level close to that of large institutions

with the implementation of new digital infrastructure technology represented by 5g, blockchain technology will be combined with AI, Internet of things, cloud computing and other cutting-edge technologies, enabling the construction of economic fields including logistics and other real instries

through the blockchain network, we can change the traditional management and service mode, promote department collaboration and business process optimization, rece communication and information costs, and improve management efficiency. The four major applications in the direction of process optimization, logistics tracking, logistics finance and logistics credit will be graally implemented in the fields of e-commerce logistics, shipping logistics, special logistics and logistics finance

10. Go to the internet post bar virus bar, there are tutorials. You can also install a Kaspersky (there is a special killing tool). If you can't, go to the computer virus for help. The talents there are more professional
