blockchain technology is not only the underlying technology of bitcoin, but also the core and infrastructure of bitcoin bitcoin has been running without any centralized organization operation and management. Later, bitcoin technology was abstracted, which was called blockchain technology or distributed ledger technology
extended data:
disadvantages of blockchain technology applied to digital currency:
first, there is no circulation management organization for "decentralization" blockchain technology is essentially a distributed database system with one-way linked list logic structure and P2P network design mode, which determines that there is no unified central control system for virtual currency based on blockchain technology
Second, it is difficult to effectively control the quantity supply the circulation of virtual currency based on blockchain technology is fixed, and according to Fisher Equation, the total transaction volume of the whole society under a certain price level in a certain period has a certain proportion with the required nominal currency volume, while the constant currency volume obviously can not meet the requirements of the growing total price of social goods Thirdly, "mining mechanism" is difficult to create recognized value bitcoin itself has no value and no national credit support. Some people think that "by continuously consuming computing power and energy to inject value into virtual currency", but it is obviously not the most efficient choice to consume millions of calculations in order to find a hash value that meets the requirements Fourthly, procers and early holders are easy to get high seigniorage any virtual currency based on blockchain technology is held by a few people at the initial stage of its development. Take bitcoin as an example. At first, bitcoin was only a proct of a few people's game. The first bitcoin purchase in May 2010 was $10000 BTC's purchase of $25 pizza. The first bitcoin transaction completed in July of the same year was $0.04/btcyou can't help it if you have money
in a few days, the safe also released the blockchain development plan. It seems that the whole world will be transformed by blockchain. Many people have a kind of blockchain application, which will give the currency transaction and foreign exchange transaction a false identity
blockchain has a natural anti censorship international nature in terms of asset transaction and circulation, and can freely and conveniently circulate without the constraint of traditional concurrent management. On the one hand, there is a great risk, so the safe also said that in China, only RMB can be used for pricing, and anything that may threaten this basis should be prohibited. In a short period of time, it may be difficult for blockchain to achieve anything at the level of foreign exchange transactions. The foreign exchange bureau mentioned the application scenarios of blockchain technology in cross-border trade financing and macro Prudential Management. This direction belongs to the pure technology application direction, which is less related to transactions. At present, it is also the direction that the top priority is to develop, using blockchain technology to optimize the real instry
how to optimize it? Because blockchain has the characteristics of traceability, distributed transparency, tamper proof, etc., for example, in cross-border trade, the data of related parties involved in trade are linked and opened to third parties (such as banks) with permission. In the past, enterprises may need more practical asset mortgage to borrow money from banks, Now, by associating reliable trade data on the blockchain, the bank can know the future cash flow of the enterprise, and can use the operation of the enterprise as asset mortgage to give credit. This will greatly optimize the allocation of assets
another example is the patient information in the hospital. The traditional scenario is that the data of each hospital is independent. Every time you go to a new hospital, you will be asked to do a booklet or a set of examinations. If there is a medical chain open to all hospitals and all information is recorded in this account book, you can avoid a lot of plication and simplify efficiency
it is clear that the priority is to develop blockchain technology to optimize and transform traditional instries, with the focus on the combination with the real economy. I am also very optimistic about this, but in terms of asset trading, the expectation of currency trading and foreign exchange trading should not be too high. After the excitement, it will be calm.

To tell you the truth, this question will become very big if it is unfolded. If I want to write clearly my personal feelings from the beginning to the end, it will become smelly and long. So I want to use a few simple aspects and my personal views to answer this very difficult question
let's briefly talk about what bitcoin is, because this simple problem is misunderstood by most people at present. Because it is called "bitcoin", because there is a currency, this word naturally equals to RMB, US dollar, franc and other legal compensation currencies. In fact, this is totally wrong. The definition of legal currency is "the currency given by the state in the form of law for compulsory circulation". When bitcoin appeared, it was written in the white paper that the e-cash system was completely realized through point-to-point technology, which enables online payment to be directly initiated by one party and paid to the other party without any financial institutions
so what exactly is bitcoin? To be exact, it should be regarded as a commodity rather than a currency, because you can see in the white paper that "there is no need to go through any financial institutions". When bitcoin was created by Nakamoto, it was intended to change the life of the bank which was not trusted by the people because of the economic crisis. But we say the vision is good, but the reality is cruel. Even Alipay with 1 billion users can't get rid of the bank's life, let alone a small bitcoin. p>
but you can say why bitcoin is still used by many people for trading and its price is not low, that is because its market demand is very large, resulting in its high price. What is this demand for? Let's talk about it next time. In a word, its high market demand leads to high price. What is bitcoin? I prefer to compare it to a hard currency or a very scarce commodity. Like gold. Let's take a look at an interesting figure:
to tell you the truth, the development of blockchain is very, very early now. All of a sudden, so much capital has poured in, which makes everyone crazy. When the slump comes, it's a bit at a loss. Now the price of bitcoin is more stable, which gives more time for many people who are calm down to do things
out of trust in blockchain technology, bitcoin, as the genesis currency of blockchain, will have a place in the future. Money price is not the most important thing. But make a bold guess. Bitcoin or digital virtual currency will definitely recover in early 2020 and mid-2019. The bull market will come at that time. Is it possible to go back to $2W? Maybe more. Maybe
in the future world I imagine, blockchain technology will surely create a happier and better future for mankind. And the accompanying bitcoin will certainly lead to a bull market
is to read more about the various currencies or project's white paper. I pay attention to my WeChat official account: "Nanjing block chain" can get thousands of white papers free of charge, so that you will have a better understanding of the chain world. p>
There is no problem with the monitoring disk for hard disk mining. The monitoring level hard disk is mainly used to store video images in the monitor, and the reading and writing speed is relatively good. It's enough for ordinary miners
but if you want to have better speed, read-write speed and stability, you need to use enterprise hard disk. Because the enterprise hard disk will perform better than the monitoring disk in this aspect, and the enterprise hard disk is not easy to make mistakes in the storage process, so it can rece the profit risk of hard disk mining as far as possible
many hard disk mining machine service providers purchase enterprise disks for assembly. Of course, it's not good to use ordinary hard disks, because both enterprise disks and monitoring disks can operate for 7 * 24 hours. Ordinary hard disks are very easy to be damaged after digging for such a long time
bitcoin broke through the $50000 mark, and its value is supported by its scarcity, value preservation function and unique blockchain core technology with the continuous development of science and technology, our life has brought great changes, and emerging instries are also booming. Bitcoin, as an emerging instry, has attracted the attention of many people, and has increased tens of thousands of times in more than ten years, which has witnessed the miracle of wealth. Bitcoin broke through the $50000 mark, and its value was supported by scarcity. Because the number of bitcoin is limited, but the demand is very large, and scarcity makes it more valuable. Bitcoin has unique blockchain core technologies, which are the core competitiveness of technological change. At the same time, bitcoin also has the function of preserving value, which is also the reason for supporting the value of bitcoin
I suggest that ordinary people should not participate in bitcoin, because the price of bitcoin is very expensive. It costs about 300000 yuan to buy a bitcoin. Moreover, the fluctuation of bitcoin is very large, which means that the risk is high. Ordinary families may not have the ability to admit it. Therefore, I do not recommend ordinary people to participate in bitcoin. This position is relatively high, so I do not recommend participating
