Application of virtual currency
bitcoin price has been cut by the waist
how to implement blockchain application is still the main problem. In addition to bitcoin, the large-scale application of blockchain in other scenarios has not yet reached the commercial stage. Looking back to the second half of 2017, the price of bitcoin almost reached a new high every day, and finally reached the peak in the South Korean exchange with the highest premium in the world - about 140000 yuan per piece. On June 3, 2018, as of press time, coinbase bitcoin trading platform quoted 49688 yuan, and the price of bitcoin has been cut. Since the beginning of this year, the price of bitcoin has rarely seen eye popping ups and downs, and the overall trend of monthly decline
bitcoin development status
according to the data of the in-depth analysis report on business model innovation and investment opportunities of the blockchain instry released by the foresight Instry Research Institute, bitcoin prices showed a downward trend in May, with the overall market value falling from US $157.3 billion at the beginning of the month to US $127.4 billion at the end of the month, a decrease of 19%; In addition, there are 444000 active addresses and 197000 transfers per day. From the trend point of view, the number of active addresses and daily transfers are positively correlated with the transaction price. In May, the overall trend is volatile, and the downward trend is very obvious
reasons for the steady decline of bitcoin in the past half year
how to understand the "steady decline" of bitcoin in the past half year? There are two main reasons: firstly, the most important reason is that institutional investors and speculators who have accumulated a large number of "profit" are cashing in their profits and leaving the market; Secondly, before the blockchain instry has no real application and profit model, the rise of bitcoin price can only be regarded as speculative speculation. In addition, it is an undeniable fact that the Central Bank of China has made a decisive move to close the bitcoin trading platform, which has achieved remarkable results in preventing bitcoin speculation
at present, the domestic bitcoin exchanges have basically moved to foreign countries, which has nothing to do with China. Investors operate on those platforms at their own risk
the current market is not very good. Only when the market is good, can investors find ways to participate in bitcoin investment. As the total market value of the coin circle is still small, with more blockchain applications, there is still potential in the future
over consumed blockchain
e to the "tepid" price of bitcoin, blockchain, as its underlying technology, has reached the level of "known to all women and children", and even surpassed bitcoin in recent years
recently, a series of related reports are suspected of making up for the number and full of hype, and blockchain has obviously been over consumed. In addition to bitcoin, the large-scale application of blockchain in other scenarios has not yet reached the commercial stage
with the graal deepening of the understanding of blockchain technology, domestic enterprises have laid out blockchain technology, platforms and applications, including Internet enterprises such as network, Tencent, Ali, Jingdong, Netease, major banks, financial enterprises such as Ping An of China and Huawei. In terms of application, China actively explores and promotes blockchain + applications in the form of alliance chain and private chain to help solve the pain points of related instries, improve efficiency and rece costs.
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 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

Anti counterfeiting, such as frog coin and Weilian the source and process of frozen food monitoring of final procts such as imported milk powder and luxury goods: red wine, bags and refrigerators, because it is impossible to cheat by writing into the blockchain Back modification is being implemented or has been implemented (only the chain's partners are very strong)
smart contract or intellectual property rights, such as publishing a song. In the blockchain, you own the song, use the smart contract to sell and protect the property rights, such as Neo and Ethereum. Game development or program development: for example, cryptokitties are free to breed and trade different kinds of cats without age or rarity (the closer the age is, the more expensive it is)
