Background: the financial application of blockchain technology brings high investment value

2018 China international big data instry Expo opened in Guiyang City, Guizhou Province on the 26th. At the meeting, it was pointed out that China will vigorously develop the digital economy in the future, deeply implement the action plan for the development of big data and cloud computing, and deeply study blockchain technology and application. Especially in the field of finance, the landing application has become the focus of the scientific and financial circles

1. The value source of blockchain is that it can perfectly solve the pain points of the current financial instry:

in today's asset securitization, insurance, supply chain finance, commodity trading, asset custody and other financial scenarios, e to many participants, high cost of credit evaluation, low settlement efficiency of intermediary institutions and other reasons, Traditional financial service methods are difficult to effectively solve the long-standing core pain points in the instry, such as information asymmetry, complex and rendant processes, and high information verification cost

2. Why can blockchain solve the above pain points:

blockchain technology integrates many basic technologies, such as distributed accounting, tamper proof, built-in contract, etc., and constructs a trust building mechanism with lower cost. The financial application based on blockchain technology can realize the ability of all market participants to obtain all transaction information and asset ownership records in the market without discrimination, and effectively solve the problem of information asymmetry; Smart contract embedding reces the error rate of payment and settlement, simplifies the process and improves efficiency; At the same time, based on transparent information and brand-new trust mechanism, there is no need to spend manpower, material resources and financial resources to confirm information among participants, which will greatly rece the trust cost between institutions, and then rece the price of financial services and transaction costs

3. The application of blockchain technology in the financial field mainly includes the following aspects:

① digital currency

among which bitcoin is the most famous. On the basis of bitcoin, a large number of other types of decentralized digital currencies have been derived. Such as: the heyday of bits

Compared with the traditional payment system, blockchain payment can directly carry out end-to-end payment for both parties without the help of the banking system, which can greatly improve the speed and rece the cost

③ digital bills

④ bank credit management: the advantage of blockchain is that it can rely on program algorithm to automatically record credit related information and store it on every computer in the blockchain network, with transparent information, tamper proof and low cost

The major financial institutions and exchanges in Europe and the United States have explored the application research of building the next generation of financial asset trading platform based on blockchain technology

4. The development prospect of blockchain. The future development of blockchain technology will have the most vitality with alliance chain as the entry point, and will have a significant effect and far-reaching impact on the transformation of traditional financial instry pain points

in response to the good investment prospects of blockchain, domestic enterprises such as Alibaba, Jingdong and Netcom have entered the market. The application of financial scenarios based on blockchain technology not only brings us security and convenience, but also provides us with broader investment space. The rise and price surge of digital currency represented by bitcoin (bitcoin was about RMB 20 cents when it was first listed in 2009, and its current price is about US $7300!) It's the best proof that people with a keen sense of smell have made a lot of money from it

Abstract: This is an encrypted digital currency based on the bitcoin developed by Nakamoto Tsung, which improves and adds many new functions, such as the double-layer reward system network, also known as the main node network. It also includes anonymous payment to improve the interchangeability (bitage) and real-time payment function docking to realize real-time transaction confirmation without relying on the authority of the center (P2P mall)

In 2009, Nakamoto put forward the concept of bitcoin. Since then, bitcoin has spread rapidly in mainstream applications and commercial uses, becoming the first digital currency to attract a large number of users, which is a milestone in the history of digital currency. However, from the perspective of completing the transaction, we can find an important problem, that is, it takes too long for bitcoin block to confirm the transaction. Traditional payment companies have found a solution to enable the buyer and the seller to realize zero confirmation of bitcoin transaction, but this solution usually requires a trusted third party to complete the transaction outside the agreement

bitcoin provides pseudonym transaction, realizes the one-to-one transaction relationship between sender and receiver, and can always record the transactions occurred in the whole network. Bitcoin only provides low-level privacy protection, which is well known in academia. Despite this deficiency, many people still believe in the transfer history recorded by blockchain

based on Nakamoto's achievements, bitshengshi is an encrypted digital currency with the purpose of protecting privacy. We have made a series of improvements on the basis of the concept of bitcoin, resulting in a decentralized cryptocurrency with good anonymity. It supports tamper proof real-time transactions, and has a point-to-point sub network that can provide service reward system for bitsheng network

2. Master node network

the whole node is the server running on the P2P network, so that small nodes can use them to accept the dynamic changes from the whole network. These all nodes need significant traffic and other resources that consume a lot of cost. Therefore, it will be observed that the number of these nodes on the bitcoin network presents a steady downward trend over a period of time, so that the block broadcast time needs an additional 40 seconds. In order to solve this problem, many solutions have been put forward, such as the introction of Microsoft Research's new incentive plan and bitnodes incentive plan

4. Don't listen to others any more. I've experienced it myself. Fortunately, I have to go back. Don't worry

5. It doesn't need a license to operate virtual currency in China. China's attitude towards virtual currency is neither positive nor negative. In the bitcoin risk notice jointly issued by the central bank and other five ministries at the end of 2013, bitcoin was clearly defined as a special Internet commodity, and people can buy and sell it freely at their own risk. It is required that bitcoin trading platform must carry out website filing, and users must carry out real name authentication for transactions

to carry out bitcoin related business in New York state of the United States, you need to apply for a license from the Financial Services Department of New York state. At present, one enterprise has successfully applied for the license

at present, most bitcoin related companies in China adopt corporate operation. The website also basically carries on the record. In China, there is no record of virtual currency related website risk is great. Fuyuan currency trading platform has also been put on record, and the information is public.

Rtx3080 was launched on September 24, and the time for lifting the ban has yet to be determined

There will be multiple versions of rtx3080, including 10g and 20g versions. The core specifications are the same. Rtx3080ti has 24g video memory, which is amazing. Rtx3080 will be 20% ahead of rtx2080ti. The specification of rtx3080 identified by gpu-z is unknown, and the maximum limit frequency is 2.1GHz, but it is not acceleration frequency. In fact, rtx20 series is also similar

the gddr6x video memory with matching frequency of 4750mhz has a capacity of 10Gb. The total bandwidth is 760gb / s, which is 53% higher than that of rtx2080super

{rrrrrrr}

extended data:

precautions:

the power consumption of rtx30 Series graphics card is greatly improved, reaching more than 300W, which means higher requirements for power supply

Generally speaking, power consumption = graphics card power consumption + CPU power consumption + other hardware power consumption (60w-120w, depending on the number and total power consumption of other hardware, note that TDP is not equal to power consumption)

The frequency of 4266mhz is 16% higher than 3200mhz. Although memory is very important to improve the performance of graphics card, the influence of memory on performance can not be ignored

The concept of virtual currency has penetrated into our life with spirit. Not only bitcoin, which was very popular before, but also virtual currency with different forms and concepts in our life. So how many types of virtual currency are there? Have you ever bought virtual currency before mobile phone payment mobile payment in some sense, it can be said to be the payment of virtual currency.

virtual currency has too many conceptual procts, but in our life, we can hardly leave the mobile phone because we can pay mobile phone in some public places, such as bus card, and some group receipts in work and study, which can be paid by WeChat or Alipay. Very fast and convenient to complete. This is one of the reasons why people choose virtual currency to pay{ RRRRR}

virtual investment is graally rising, and we should also be clear eyed

at the beginning of the stock speculation in the last century, our country has also begun to have a lot of investment forms. But now we can't invest. The display is operated by virtual currency, but the network is virtual after all. Therefore, while investing in virtual currency, we still need to calculate the risk

8. Why can't Huabei pay?
your Huabei status is normal. If you can't choose Huabei payment ring payment, it may be the following reasons:
1
2. If multiple goods are paid together, and one of them does not support Huabei payment, Huabei cannot be used in the combined transaction
3. According to your current transaction, the system will evaluate whether you can support flower payment or not. Due to different evaluation results, even for the same goods and stores, you may be able to pay today but not tomorrow

at the same time, if you have a red envelope in your current account, it may be e to the following reasons:
1. When using the red envelope dection, you need to ensure that the order amount is greater than the red envelope amount< When br />2. is paid, you need to choose "flower chant" as the payment method to use on Alipay wireless.
3. Huabei red envelope supports offline physical stores, taxi, online shopping and other scenarios (but Huabei red envelope does not support the purchase of virtual goods, including but not limited to virtual currency and other virtual goods). The red envelope of Huabei physical store only supports payment in physical store
4. When making offline payment, the store needs to open the function of "collect money by paying", which can remind the seller to confirm

at the same time, under the condition of meeting the above red envelope rules, the system will also automatically detect both sides of the transaction and the transaction situation. If the transaction is real and effective, the red envelope can be dected
if you are still unable to use it, it is recommended to change the merchant or try again the next day

warm tips:
the system will evaluate whether the payment can be made by using flower according to the transaction situation in real time, which cannot be intervened manually.

9. Hehe, it's hard for newcomers to get KB. It's like getting red envelopes for newcomers. There's a red envelope in "member benefits", a special gift for newcomers!

10. Virtual currency investment needs to be cautious. Once the capital chain is broken, do you understand? It's not reliable. It's suggested to invest in the health instry. It's also a development trend instry. I don't know cocoa nickname exchange.
