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:
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 cost③ 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 technology4. 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 agreementbitcoin 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

daily tasks: (3 times of equipment manufacturing + 3 times of humanoid manufacturing + 15 times of repair + 3 times of simulated combat + 5 times of customs clearance) can get 5, and a month is 150
weekly tasks: if you calculate as 4 weeks, 5 times of skill training (1 purchasing currency) + 100 wins (2 purchasing currency) + 10 boss tasks (2 purchasing currency) can get 5, and a month is 20
expeditionary gains, Even if you hang up the expedition with purchasing currency on time every day, and you can get one purchasing currency every expedition, one for 0-4 (24 hours) a day, two for 6-4 (12 hours), three for a day, and 90 for a month
if you don't spend a cent, you can get 260 purchasing currency in a month theoretically, If you want to buy money for your skin, you must buy at least 2000 yuan. Even if your face is black to the extreme, you can get a 200 coupon skin at least. Or 100 coupons for two skin, one for a black card
by the way, don't run 0-4 expeditions every day just because you can (have the probability) get the purchase currency. Run 6-4 is enough for blood loss. The essence of this game is to build up the resources to practice and push the map. The skin doesn't improve the combat power at all. If you really want the skin to be krypton gold or krypton. Pay more attention to the latest official activities. It's possible to send purchasing currency. Sometimes, you can learn to calculate the price of the special gift package sold in the store. If you have a discount, don't hesitate
he didn't do it because he was cheated by the swindler and he lost tens of thousands of yuan one day, while playing with mobile phones, children working outside saw an investment advertisement in their circle of friends. They could easily make a profit of several hundred yuan a day. In the face of this temptation, I believe many people may be attracted. As you expected, the girl born in 1990s was cheated and introced into the capital market by a swindler, although after prosperous operation, The staff began to guide the post-90s girls to make money
First, because of greedthis time, the operation mode of the fund disk is different from the fund disk that you usually encounter. In the early stage, they let the post-90s girl achieve violent profits, because only in this way can the post-90s girl trust the staff's technology more. In this way, the post-90s girl has completely entered the routine of swindlers step by step, Because in a short time, the staff really helped the little girl make tens of thousands of yuan{ RRRRR}
this is my opinion. I have other ideas to discuss below
-
this is a billion Dinar note issued by Yugoslavia (today's "Serbia") in 1993. The front of the note is a girl of the Serb nationality, and the back is the federal parliament building of Yugoslavia
-
this is an old version of the Yugoslavian banknote. Now it has stopped circulating, so this kind of banknote can't be changed. It has only collection value. At present, it is worth 25 yuan / piece in the coin collection and trading market
and you said that Yuner can make money very much. That's right. In the first half of 2012 alone, Yuner earned more than 4 billion won (about 22.16 million yuan), which is also the first income of Korean artists (including male and female artists and groups)
it can be seen that Yuner and her group are more popular in the girlhood.
Guanghui collection can draw out the previous four-star and five-star furniture and unlimited skin (as well as a pile of Samsung furniture that lowers the winning rate) for 6 yuan
purchasing currency can be obtained from two logistics, several daily tasks, and sometimes some tasks will be sent
