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

physics
alternating current refers to the current whose size and direction change periodically, which is widely used in power transmission (i.e. AC transmission). After Michael Faraday discovered electromagnetic inction, the principle of alternating current has been revealed. In 1891, Nicolas Tesla obtained the patent of "high frequency" (15000 Hz) alternator< In the process of porosity logging, acoustic time difference is used to reflect the curve data of lithology and rock structure. Because acoustic can be written as acoustic, AC is used to refer to this data
attenuation coefficient, also known as attenuation constant and attenuation coefficient, refers to the change or loss of a certain substance or physical quantity (light, sound, electricity, heat, pollutant composition in water body, etc.) under the influence of other physical phenomena (medium density, humidity, temperature, etc.) under one unit measurement. If sound propagates in the air, it will be affected by the viscosity of the air, heat conction (classical absorption) and relaxation effect (molecular absorption) of the vibration of oxygen and nitrogen molecules in the air
chemistry
actinium (element symbol: AC) is a metal element with extremely strong radioactivity. It was discovered in 1899 and exists in pitchblende or uranium bearing minerals, resulting from the decay of uranium. Its atomic number is 89. It belongs to actinide. Its radioactivity is about 150 times that of radium. It can emit blue and white light in the dark. Because actinium content in nature is very low and difficult to extract, it is generally prepared by irradiating thorium-226 with neutrons in nuclear reactors. Its applications include medical tumor therapy and neutron source
acetate, also known as acetate, is a proct formed after the carboxyl proton (h-hydrogen ion) of acetic acid is replaced by other metal cations, such as sodium acetate (NaAc). At the same time, acetic acid itself can also be written as HAC. The molecular formula of acetate is CH3COO - or [c2h3o2] -, which belongs to one of carboxylate ions
acetyl group is an acyl functional group composed of methyl and carbonyl groups in organic chemistry. The molecular formula is ch3-c = o-r or CH3C (o) -, also known as AC -. Acetylation is a chemical reaction in which acetyl groups are introced into molecules by acetylating reagents (acetyl chloride or acetic anhydride are common). Compounds containing acetyl group can react with halogen under alkaline conditions to form haloform, which is called haloform reaction

Azodicarbonamide (azobisformamide) is a non-toxic, odorless, incombustible compound, soluble in alkali, insoluble in gasoline, alcohol, benzene, pyridine and water. Its molecular formula is c2h4o2n4, which can be used as food additive and foaming agent
activated carbon is also called activated carbon black. It is black powder or granular amorphous carbon. The main components of activated carbon are oxygen, hydrogen and other elements besides carbon. This is the reason why activated carbon is a hydrophobic adsorbent. In addition to I carbon element, activated carbon also contains two kinds of admixtures: one is chemically combined elements, mainly oxygen and hydrogen, which are left in the carbon e to incomplete carbonization, or in the process of activation, foreign non carbon elements are chemically combined with the surface of activated carbon, for example, when activated with water vapor, the surface of activated carbon is oxidized or oxidized by water vapor; The other kind of admixture is ash, which is the inorganic part of activated carbon. The element composition of several activated carbons is easy to cause secondary pollution
