Application of blockchain technology in petroleum field

2. 99% of them are deceiving. It's deceiving to say how much it will appreciate. It's just a technology, its application is valuable.

Fried coins or something

at present, the application of blockchain technology is virtual currency. Therefore, virtual currency is also known as the first real birth proct of blockchain. The popularity of virtual currency is also obvious to all, which has set off a frenzy of investment in many countries. According to foreign media reports, the number of virtual currency transactions in the United States has reached 5 million; South Korea is estimated to be the craziest nation in the world, with one in every 50 people speculating, and 31% of the working class buying and selling virtual currency; Venezuela has also issued the world's first virtual currency with the nature of national sovereignty - oil currency

with the popularity of virtual currency, market investors are not only satisfied with the conventional trading mode of buying low and selling high, but also actively seek more simple and convenient trading ways to obtain more profits. The virtual currency trend trading method was born and successfully captured the hearts of investors in a short time, becoming a major mainstream trading mode

according to

, the trend trading method of virtual currency is exclusively launched by speedxo, an international financial service provider with deep experience. It mainly deals with the currency pair composed of virtual currency and real currency, and it can make profits as long as it is bullish or bearish. For example, if an investor trades in "bitcoin / US dollar", he or she only needs to judge whether the price will rise or fall after 30 seconds, and buy up or down according to the trend. If he or she buys in the right direction after 30 seconds, he or she can get 93% of the net income of the investment amount. It is this kind of rise and fall are profitable, time-consuming, no need to take advantage of the market, the trend trading method quickly swept the entire currency circle

7. In the field of blockchain technology, Dao refers to the community of distributed autonomous organizations, and block is a blockchain technology community
Dao is a mechanism through which we can use software on the Internet to achieve reasonable economic incentives (allocation of risks / rewards). With Dao, people can coordinate with each other and achieve common goals on a global scale without relying on trust or a third party. Blockchain technology makes this mechanism feasible
the establishment of block community is under the background of the rapid development of blockchain, which is faced with some problems: the mainstream blockchain community focuses on media positioning, has a fickle mentality, pays attention to currency speculation and ignores the promotion and discussion of blockchain technology; After blockchain project financing, they are keen on media PR promotion, and do not solidly develop procts and build technology communities; There is no platform to focus on the development of blockchain technology, open up instry university research and government departments, and construct a complete blockchain ecosystem; There is no fair, independent and powerful third-party platform in the instry, which can objectively reflect the quality and community influence of blockchain project development
block is a community that serves blockchain developers and projects, and promotes the implementation of blockchain technology and applications.

Today, with the rapid development of information technology, real money is far from meeting people's demand for capital flow. Virtual currency is the information flow or data flow that replaces the real currency in high technology. Virtual currency is different from check and telegraphic transfer. Virtual currency can not be transferred. At present, it can only be circulated in the network world. Virtual currency is released by each network machine, and there is no unified issuance and management standard. According to incomplete statistics, there are no less than 10 kinds of network virtual coins in circulation, such as Q coin, u coin and so on. Take Q coin as an example, with more than 300 million users. It is understood that the domestic Internet has a virtual currency market scale of several billion every year, and the growth rate is relatively large. Virtual currency is a newly emerging form of electronic currency in recent years. In essence, this kind of virtual currency is a form of goods. It is the result of a series of digital program algorithms through a series of mathematical algorithms. Virtual currency is also a kind of currency in essence, which can be used for trading

one Christmas, an editor of the financial times decided to buy bitcoin, a special Christmas gift for his parents. The reason is very simple. For the first time before Christmas, the value of bitcoin exceeded US $10000, which rose more than ten times in a year. Moreover, young people in Europe and the United States are talking about bitcoin. A survey found that 30% of the 20-30-year-old people in the United States have bought bitcoin. They don't know what bitcoin is, and they will definitely fall behind. The idea of taking bitcoin as a gift, on the one hand, can let oneself also try water in the coin circle, on the other hand, can also let the elderly parents play something new

as a result, the editor, who bought a $100 bitcoin, kept an eye on the market of the exchange every day ring the days when bitcoin jumped up and down, for fear that bitcoin would plunge into the water with his gift. On Christmas day, he spent half a day wrapping the electronic money of bitcoin for his father, and it took a lot of trouble to transfer the bought bitcoin as a gift to his father. After the transfer, he received the bill - the transfer cost was $30, which could be confirmed an hour later. Dad was very happy. He called in the new year to say that the bitcoin in his account had risen to 85 yuan

bitcoin is now the most popular cryptocurrency. To understand what bitcoin is, we need to explain it in several steps. First, it is cryptocurrency. Transactions are secure and will not be tampered with, because it relies on a technology called blockchain; Second, the blockchain technology is a kind of distributed general ledger that can safely record transactions, that is, a technology that stores transaction data on all networked computers, because each transaction needs at least half of the networked computers to confirm, so it ensures the security and transparency of transactions; Third, because of the use of distributed blockchain technology, bitcoin is different from the legal tender known as RMB or US dollar. It is no longer issued by the Central Bank of a country, there is no credit endorsement behind the country, there is no central authority to determine the currency value, and there is no central trading system to verify transactions

in 2016, the economist's cover article "trust machine", which introced "blockchain", was regarded by bitcoin insiders as a landmark event for bitcoin to enter the mainstream crowd According to the article of the economist, blockchain, as an emerging decentralized technology, has broad application prospects not only in the field of digital currency, but also in many fields such as supply chain, medical treatment, real estate transaction, etc

however, bitcoin has risen from less than $1000 in early 2017 to a maximum of $20000. Although this round of rise has made it a household investment, it is further and further away from the digital currency as a substitute for legal tender

if measured by the three main functions of currency, bitcoin can not shoulder any of them. The three main intelligences are value reserve, circulation means and pricing unit. Let's see why one by one

let's look at the stored value method first. The price of bitcoin has been soaring all the way. Recently, there is a roller coaster market. The price often fluctuates 20% to 30% in one day. If bitcoin is used as a value reserve, the volatility will obviously make people nervous: if you bought a car with bitcoin in January last year, the same amount of bitcoin will be enough for you to buy the most expensive sports car in January this year

As a means of circulation, bitcoin is also very weak and not environmentally friendly. In the first example, the editor of the financial times had to pay $30 to transfer bitcoin, and it took more than an hour to get it. There is no way to compare this with the free real-time payment of wechat wallet, and even less with the system that can handle hundreds of thousands of transactions per second. The reason for this is that bitcoin has set the rule that it can only process seven transactions per second, while at least 50% of the connected computers are required to confirm, so each transaction costs 275 kwh. Bitcoin's total annual electricity consumption is enough for Morocco, a small country in North Africa. In other words, with the existing technology of bitcoin, there is no way to meet the needs of global digital transactions

Finally, as a unit of valuation, bitcoin will have problems if it is widely circulated. For example, if your housing loan is priced in bitcoin, the house price has not increased much in the past year, and your debt may have increased more than ten times if it is converted into RMB. Without a stable currency value, bitcoin could not support slightly more complicated financial transactions

then why can bitcoin Soar so much? In fact, the reason can be described in one word: fomo, which is the abbreviation for fear of missing out. Every one of us is afraid of missing this opportunity to make a fortune. If the story of people around us who are speculating in bitcoin and suddenly become a billionaire spreads, more and more people will buy bitcoin because of the money making effect. There are so many examples of such rapid bubbles in history. If many investors buy an illiquid asset, the price may double. p>

but fomo belongs to fomo, and the blockchain behind bitcoin has great potential, which is why the economist calls it a "credit machine"

some people regard blockchain as the future Internet. But the problem is that the application of blockchain in various fields mentioned above can be completed with centralized database. Blockchain has not brought advanced technology, and even has bottlenecks in the speed and frequency of transactions at this stage. So why do you do that? The answer lies in the concept of decentralization. Centralization means that all data are placed in a core database. When the database becomes larger and larger, it will face more and more security risks. Similarly, for each indivial, if data concentration in a center also gives the center great power, how to ensure that this power is not abused? Blockchain technology is the representative of "decentralized" technology. Decentralization, as the name suggests, means that there is no longer a core, no longer a center that commands and has authority, but a new organizational mode of decentralization, in which every participant is equal

therefore, the driving force behind the promotion of blockchain applications is actually to achieve a certain balance between the core and the public, that is, between the center and the decentralization. Another problem that centralization may lead to is that platform dominance will curb competition, just as our digital economy has been dominated by faang and bat. The United States is Facebook, Amazon, apple, Netflix and Google, let alone bat in China. The decentralized model dominated by blockchain can encourage the creation of new competitive markets

another point is also very important. Many experts hope to automate more processes by virtue of the transparent and tamper resistant characteristics of the data on the blockchain, as well as the characteristics of its smart contract, such as completing a transaction when a certain agreed condition is reached, and auditing the process at the same time. This feature of blockchain is particularly effective in some markets with corrupt government and lack of rules, which is why there are real estate transaction applications based on blockchain in some Latin American countries

look back at bitcoin and the explosive but problematic ICO market. Both experts and people in the instry are talking about the word "token", which is the meaning of adding a token to the chain. Bitcoin mania tells us how amazing fomo's wealth effect is. However, some experts believe that the blockchain with token can better motivate the participants to find the potential security risks on the public chain and make the blockchain based applications more efficient

Finally, although bitcoin has become a "dark horse asset" sought after by funds, the rise of crypto digital currency should still cause people to think about what money is and how money is created? If money is based on some kind of credit that more and more people think is valuable, then the next generation of cryptocurrency may open up many other possibilities. Don't you see that Venezuela, which has been plagued by inflation, has issued "oil currency"? It is hoped that this kind of petroleum currency, which claims that every petroleum currency is directly linked to every barrel of crude oil, will not collapse as fast as the gold dollar. After all, Venezuela has plenty of oil, and the blockchain itself has credit that is not so easy to tamper with

9. Oil token refers to the oil information equity certification technology based on blockchain technology. According to Reuters, oil is the commodity with the largest trading volume in the world. The annual oil trading volume is about 14 trillion US dollars, almost equivalent to China's total GDP in 2017. China surpassed the United States as the world's largest crude oil importer in 2017. Many energy companies have begun to study blockchain technology to optimize the operation process and rece costs. Oil token will become the first P2P trading system of energy procts based on blockchain technology
in Asia, the population density is relatively high, and the demand for gasoline and other fuel oil has declined for a long time e to the decrease of population and the improvement of fuel efficiency of transportation equipment. In addition, e to the "oil reform" of the United States and the slowdown of global economic growth, there is a global oversupply of crude oil. In addition, e to the problem of carbon dioxide emissions in the use of primary energy compensation, nuclear energy, geothermal energy, solar energy and other new energy has attracted much attention. Due to the above reasons, it is predicted that oil demand will continue to decline, and governments are formulating policies to establish a supply system to optimize the balance of oil supply and demand. Based on these conditions, oil dealers are experiencing a lot of restrictions and integration of facilities, as well as rationalization of logistics
more and more people believe that blockchain will lead energy trade into a new era. McKinsey, a well-known global consulting company, pointed out in a report that blockchain is the core technology with the most potential to trigger the fifth round of disruptive revolution after steam engine, power, information and Internet technology. For a widely distributed, complex and huge instry such as oil and gas, the golden age of blockchain technology is coming
the hematopoietic function of oil token is much higher than that of the traditional energy instry. With the application of blockchain technology, oil trading can achieve the maximum effective control of costs, and then improve revenue. In addition, profit from price difference in the global crude oil market is also one of the main means of making blood in the oil pass. Oil is the commodity with the largest trading volume in the world, with an annual oil trading volume value of about 14 trillion US dollars, almost equivalent to China's total GDP in 2017
because of the direct impact on their profits, it is very important and urgent for logistics companies to rece fuel costs. Oil pass is a digital technology that creates new profit opportunities by matching the needs of these two things with each other. Specifically, gasoline can be purchased more cheaply in cash, and can be sold directly to transportation companies without the need for an intermediary agent to make a lot of profits. Part of the operating profit will be distributed to investors
it sounds tall, but in fact it's a lie. Pie falls from the sky
