Blockchain and coal
bitcoin is equivalent to digital gold. As a generally recognized equivalent, gold naturally has monetary properties and has been regarded as a kind of currency since ancient times. Bitcoin was born in 2009 and created by a person named Nakamoto. As the earliest digital currency, it was worthless at the beginning of creation. Until 2017, the highest transaction price of bitcoin exceeded 30000 RMB. The reasons why bitcoin became a valuable digital currency are as follows:
first of all, it is like gold, as a natural mineral, The total amount of bitcoin is limited. Bitcoin can not be over issued according to its own algorithm, so there will be no rapid devaluation of currency e to excessive currency issuance. The number of bitcoin is controlled to no more than 21 million e to the algorithm, so it can not be issued in large quantities, so its value is guaranteed
these revolutions started and ended with the creation of better and more efficient machines. But the fourth revolution, the instrial Internet of things (iiot) asserts, is coming, and it will not follow in the footsteps of its predecessors
the fourth revolution will not focus on stronger and faster machines: it will focus on machines, processing, sharing and spontaneous information behavior, fundamentally changing our relationship with tools, the world and each other
the data revolution
is not coal, steel, nor silicon. The currency of the fourth revolution will be data
a single gas turbine, coupled to the instrial Internet, generates more than four times as much data in one day as the global Twitter as a whole, but the data we analyze is less than 1%. Bill RUH, chief executive of Ge digital, predicts that digital information will overflow, and today's analysis tools are hopeless
"ten years ago, we might have introced 1TB of data every day." "Today, it's up to about 10000 TB of data," RUH told the Boston Globe. By 2020, we expect to introce about 1 million terabytes of data a day. "
the data generated by future machines is about the same as that of the library of Congress. Imagine reading every book in the library of Congress and then having to summarize what you've learned on 10 pages. The task is not only huge, but also ridiculous
the real miracle of the fourth instrial revolution will not be to proce data, but intelligent machines that can analyze these data and communicate with their peers in the network. Each networked machine will then take action to change its processes to improve efficiency and feed back its changes to the network
I hope these smart machines will bring our world economy to a climax: RUH and Ge believe that in the next 20 years, the smart machines and Internet of things instry will add 10 to 15 trillion US dollars to the global economy. Given that global gross domestic proct (GDP) was about $74 trillion in 2015, this is a huge growth
the foundation of the revolution
for the coming revolution, there are two components that are important and necessary: a centralized, instry-specific Internet communication network, such as predix of General Electric; And systematic, decentralized way, and hinder dishonest communication to promote business development
the specific iiot network must act as a hub for intelligent machines to interact with each other and with human creators. Sensors on the computer collect a large amount of data, and then filter the data in real time. In other words, it can be imagined that it happened on the basis of a machine. However, the investigation results of relay equipment and the decision made without human intervention, in order to truly build an intelligent network, the machine needs a single communication network
imagine that when the aircraft is still in the air, the sensors of the aircraft engine recognize the part that is about to fail, and then communicate with the destination airport. The engine will need maintenance and order replacement parts before landing
this intuitive machine is not a science fiction dream: it's our future
in my opinion, iiot information network is only half the success, and ultimately it is about e-commerce. Seeing it as a public road, millions of autopilot cars will run on top one day.
now, these autopilot cars run on a single system. But how do we ensure that every autopilot will obey the traffic rules? For example, how can we ensure that the vehicle does not send fraud information about its whereabouts at the time of the accident? If there are only two parties involved in the accident, then each passenger will confirm the story of his own car, and there is no way to verify the position claimed by each party
considering that decentralized, satellite based GPS will affect the situation. The system is just and connected to every car. Of course, every car can continue to lie, but it's much easier to verify which side is telling the truth
e to the nature of the GPS system and the nature of its cancellation, the autopilot car has no reason or is tampered with by its owner. This strong incentive for integrity is to promote the trade between autopilot cars, and it is necessary for owners to feel that their investment in these vehicles is safe. Br />GPS technology is for auto driving vehicle, just like network block chain technology for instrial Internet. Of course, self driving cars can run on roads without GPS, but their owners probably will not allow them to do so. Similarly, on a larger scale, machines can communicate on a single, centralized network of the instrial Internet, but only when there is no risk blockchain is the core part of bitcoin technology. Its function is simple and similar to an account book, recording all transaction data. This account book: 1. It is stored on each bitcoin node of the Internet, and each node has a complete backup; 2. It records all bitcoin transfer transactions since the birth of bitcoin; 3. The ledger is stored in blocks, and each block contains some transaction records. Each block will record the ID of the previous block, forming a chain structure, which is called blockchain; 4. When you want to initiate a bitcoin transaction, just broadcast the transaction information to the P2P network, record your transaction information as a new block and connect it to the blockchain, and the transaction is completed
blockchain has stimulated the revolution in other places
of course, blockchain has promoted the development of e-commerce in the financial instry. But digital information packets are discrete assets like money, and blockchain can create digital records of their existence and transmission. The technology is essentially a unified ledger of records or digital events. The ledger is distributed in the network and shared by different parties, and can only be updated by the majority of these parties. Once a ledger item is created, it can never be erased
blockchain is the missing link in the revolution, because the e-commerce it inspires will define the trust between machines and stakeholders. For example, Volkswagen's recent emissions scandal. VW's tests show that its vehicles emit too much NOx, so it chooses to hide the problem to avoid subsequent inspection
although blockchain will not prevent machines or people from tampering with data, it will create transparent, shared and indelible documents about the original emission data. If this data has been created and shared through the blockchain system, Volkswagen will never embark on the road of fraud, because the difference between the two data sets is obvious
the benefits of iiot are obvious. We have developed machine to machine communication technology; Now, it's the standardization challenge between society and the next revolution. This has driven the development of database technology in the past 30 years, and we have finally seen the momentum of construction
the first mock exam is different from the other enterprises, but if we all want to benefit from the high efficiency brought by the fourth instrial revolution, we must adopt the single mode of machine to machine electronic commerce. And because the communication network has to operate commercially between voluntary participants, we have to integrate the blockchain into this system. In the need to constantly modify the data, and free information trade needs detailed environmental conditions, blockchain is the best path to a new instrial revolution.
bitcoin is a virtual digital currency. You can register an account on a professional trading platform and sell or buy bitcoin through advertising. Uto market as a professional bitcoin trading platform, its security, convenience is generally recognized by everyone, the important thing is that the transaction will not charge fees
nowadays, it takes a lot of time and money to raise a girlfriend, a family and a child. I always want to earn more. You can try bitcoin
at present, bitcoin is the mainstream currency, and people's cognition of bitcoin is also higher and higher. Bitcoin has doubled in just three months, which shows that its value has risen from RMB 25000 at the beginning of the year to RMB 80000 at present. It is very important to find a reliable trading platform. The technical team of utomarket has many years of experience in blockchain development, Professional wallet security team, unusual device IP login verification monitoring, wallet withdrawal common IP address monitoring, large amount operation manual audit, to ensure the security of account and wallet funds. Moreover, at present, there is no service charge for the transaction, and the price of bitcoin is more suitable than that of similar platforms, so bitcoin is the best choice for the transaction of virtual currency.
You can participate in it with small funds. Bijing is the next generation Internet outlet. The following is my investment experience in the past year. I hope it can help you
taking advantage of the holiday to relax physically and mentally, I took stock of the pits I stepped on and sorted out the gains and losses. My experience is as follows
1. In the early days, I believed too much in the big V of the coin circle and bought some coins from their platform. Now it is close to zero. I feel that I am really naive to believe their lies. In the face of the temptation of huge wealth, people can hardly stand the test. Of course, they can't get beyond it. However, if they don't accept what they say and do, they will lose their moral bottom line. They make a lot of money, leaving me shivering on the top of the mountain
two, the official account of the currency circle and all kinds of media, the judgement of the market trend is almost the same as that of the throwing dice. Of course, this is not to say that the media are totally irresponsible, or that they are not competent at all. In fact, some media are more reluctant to feather their feathers and do their best to analyze projects for fans and judge the trend. But don't forget, in essence, the market is unpredictable, otherwise it will not be called the market. Makers and leeks are always playing cat and mouse games. The prediction of the media will often provide the smart makers with reverse action guide. When most media are optimistic about the market, it is also the time for the makers to raise their sickle; When the media generally think that the market needs further exploration, the makers may be stealing Yu Jiancang, which is not difficult to understand, because the media acts as the opinion leaders of leeks
Third, the current market mainly shows the characteristics of investment gold plate, with speculation as the main factor, and the real block chain value investment has not been reflected. The performance is that almost all counterfeit currencies are linked with the rise and fall of bitcoin. Why bitcoin? Because there is no other standard to rely on. If there is no killer application, this linkage effect is difficult to break, and there will not be a real bull market in the currency market. The killer applications mentioned here are not like Ethereum, such as issuing currency and being an underlying public chain, but have real landing application scenarios, which can link the virtual digital assets on the chain to the supply and demand of real scenes. At the same time, DAPP should have a good user experience and be accepted by the public outside the coin circle. In this way, digital currency will have real support, and the development of blockchain will usher in the spring, otherwise it will be speculation Fourthly, we often set out from the historical phenomenon to form the expectation of the future. In 2017, some counterfeit coins went out of the market 100 times or even higher, so I always felt that the counterfeit coins in my hand had gone up three or five times after I bought them, which was not enjoyable and not in place. As a result, I didn't sell them in time, so it was rotten in my hand. To analyze, this is not the time. At that time, there were less projects and more funds. At this time, there were more projects and less funds. The situation is just the opposite. Ignorance and greed are very dangerous. Since 2018, with the big V's profits leaving the market, the funds in the market have shrunk significantly. Even the rising market is the game of the original funds in the market, and the profit-making effect is getting smaller and smaller. The funds outside the market are waiting and waiting. Only when there is a wealth making effect, can the funds outside the market have the impulse to come in Fifthly, new ways of playing appear constantly. As the effect of making money is getting smaller and smaller, new leeks become old ones. Traditional harvesting methods are difficult to cut down the order. Only by making some innovations can leeks flock to the market. Fcoin trading, mining, firebull video and so on, has made a small number of people rich and at the same time, it has made a large number of people miserable. In essence, these projects are all capital games of drum beating and flower passing, with no change in dressing or soup. The earlier we participate, the more accounting we have. When we wait for leeks to participate, they are basically in the middle and late stage. If we put money in, they will be harvested. I, fcoin, because I participated earlier and made a small profit, but firebull participated later and was cut as soon as I went in. Fortunately, I only tried to cast a little bit Will the market rise again? The answer is yes. In two ways. On the one hand, blockchain is the trend in the future, which has formed a consensus. It is said that there is a rule that can prove whether a technology can become a trend in the future. It depends on whether the number of articles published on this technology can multiply every year. Blockchain is fully in line with this rule. On the other hand, as mentioned above, the current market is mainly capital market. So even if blockchain is not the future trend, it will still come out of a good market. Because the characteristic of the capital market is that when the capital enters the market, the market will rise, and when the capital withdraws from the market, the market will come down, and there is no reason for the capital to enter or leave the market. At present, there are not only retail investors, but also large investors and institutions in the market. What is covered is not only leeks, but also makers who cut vegetables but did not cut them. No matter who is in the currency circle, there is only one purpose, that is to make money. If the market doesn't rise, there will be no big money making effect. If it falls for a long time, it will rise. This is an irrefutable law. Of course, whether indivial investors can make money depends on their own fortunefuture plans:
first, the best policy. Strictly control the position, adjust the layout and stay away from the air currency. Position control is always the first and the lifeline of investors. After losing money, we realized the importance of position control. Now I really regret that if I didn't enter the warehouse, I wouldn't be so deep. So far, decisively clear all the air projects, and more or less free up a little money. Then, select a few high-quality projects to make fixed investment, if the funds are not enough, a small part can be disbursed from the daily income. To do this well, we need to make up an important link, that is learning. In the past, I didn't know whether the project was good or bad, but I didn't learn enough and my skills were shallow. It's better to focus on study than on reading the market, consulting the public number and asking for information. The accumulated knowledge and skills are also a kind of wealth, and no one can take them away. It is necessary to learn the basic knowledge of economy, finance and investment, as well as the knowledge of blockchain. I have read some books (general knowledge of economics, one course of economics, Xiangshuai's finance course at Peking University (I get a subscription, but I can't provide an electronic version), buffet's rule, buffet's Guide to read financial report, blockchain technology guide, decoding blockchain complete works), and give the link address (link:

extract code: SBMV) you can download it when you need it Second, the medium strategy. Do oversold rebound. Small earning effect does not mean no earning effect. We must invest small funds in one or two projects, and we must go in and out quickly when there is a sharp drop and most people feel panic. We must not be in love with war You can focus on one or two big public accounts to judge the panic of the market.) Third, the worst way. Make a wool party. On the premise of not wasting energy, it's OK to get candy and some welfare. In the current market, grasshopper is also meat. The traditional way of getting candy is too cumbersome. We found two candy delivery platform projects, one is the fulcrum:the other is the ant Miner:
the former airdrops all kinds of candy from time to time, and at the same time has the social attribute of the community. It operates in a systematic way and obtains the strategic investment of coin safety and fire coin; The latter is a brand new candy game platform of candy world, which accumulates candy in the form of chicken laying game. It is reported that it has just won the strategic investment of gbls (Global sleepless blockchain Leaders Summit)
in addition, some dapps in the testing stage are also worth a try. Anyway, it doesn't involve any energy. It's just a way to relax after work. Fighting video (IOS version: https://fir.im/51ds Android version: http://a.app.qq.com/o/simple.jsppkgname=com.xysk.mvpart.douxi , invitation code: wn4viz), focusing on the vertical segmentation of professional artists, fans can accumulate star power and sign in every day to get stars. Stars can be exchanged for prizes or sold in private. October is the right time to go online
it's like wechat that we use every day, dealing with so many chat messages, transfers and so on. These data are stored and run in Tencent's server. Then the server that processes data can be called "node"
in addition to the world of blockchain, we all know that blockchain is a decentralized distributed database. It does not rely on any centralized server, but is composed of tens of thousands of "small servers". As long as we download a blockchain client, we will become one of the thousands of "small servers"
in this way, if we want to play blockchain, we are equivalent to a node
nodes are also divided into light nodes and full nodes. The whole node is the node that has all the transaction data of the whole network, so the light node only has its own related transaction data node
moreover, the more widely distributed the nodes are, the more decentralized the blockchain network will be, and the more secure and stable the network operation will be. The existence of nodes is the representation of distributed blockchain, and also the charm of blockchain
