1. Analysis of the application of blockchain Technology. Although theoretically any instry related to digital network can be applied, from the perspective of landing cost, the following instries are more suitable for blockchain technology
as the essence of blockchain is a distributed accounting book, digital currency represented by bitcoin and Ethereum is also a very simple and safe settlement method. In the financial field, the most important process is bookkeeping and clearing. Through blockchain technology, the efficiency of traditional banks and financial instry can be greatly improved
however, all of the above also play the basic functions of blockchain, and there is still much room for improvement. At present, there is no mature blockchain financial project in the world, and we still have a long way to go
when it comes to the application of blockchain, the first thing we think about is the banking and financial instry. Because the essence of blockchain is a distributed accounting system, it is most suitable for the financial instry. The digital currency based on blockchain can also be applied to transactions, clearing and settlement. The security and decentralization of blockchain can ensure the security of bookkeeping. At present, major countries are exploring this application
in addition, many businesses of government agencies are also very suitable for the application of blockchain technology, such as the management of resident identity information, ownership records and proct supervision, etc. Through distributed tamper proof records to ensure the security and privacy of key information. Ireland and many other countries have incorporated this development plan into their short-term goals, which is also one of the more common application areas of blockchain
financial sector: in addition to bitcoin, the financial sector is the most widely used sector of blockchain. After all, financial development is also mixed with money and digital money. In particular, the development of digital currency in recent two years has also driven the application of blockchain
when blockchain spoofing was just emerging, it was questioned by many people and was called blockchain spoofing. Now the chief economists of all countries in the region have begun to abstain from studying the blockchain, proving that the blockchain is graally accepted by the public
in addition, e to the emergence of Ethereum contract, blockchain can also better assist resource sharing related instries, such as our common bike sharing procts. For another example, in the medical field, we can also use blockchain technology to improve efficiency and security, which is a qualitative change in this instry
I believe you have a preliminary understanding of the practical application of blockchain. Looking back at the recent ICO fever in China, a large number of unreliable projects such as dog chain are forced to speculate. Obviously, domestic investors do not know enough about the application field of blockchain. Therefore, stopping ICO not only standardizes the instry, but also protects the investing public.

2. However, after the emergence of the computer and Internet, the status of paper is no longer unshakable
ten years ago, my article was written on a black notebook. Now, all the words in my mind are entered into notebook, becoming 0 and 1, which is the change
from the present point of view, the disadvantages of paper are too obvious:
not environmentally friendly
not easy to save
for paper, long-distance transmission is very troublesome (such as information transmission)
the cost is high
easy to modify and forge
when there is a better choice in front of me, if I don't use it, isn't it a loss for me
have you ever thought that one day we won't need paper for our money
you may say:
"yes, I use Alipay and online banking every day, and no paper is used. Is this not achieved?"
indeed, Alipay's payment system is to digitize paper currency and store it in a huge database, but after all, it still needs paper money. The central bank does not print banknotes. The figures in the bank database are not too outrageous. Do you say yes or no?
can we say that the amount of money in the bank account book is the amount of cash? Of course not, because of the existence of bank loans, credit cards and other procts, the number in the bank database will only be much larger than the amount of cash, and this account book is not open, and the specific data deviation is only known to a few people
is there any payment system that does not rely on paper money, has high transparency, and no one can tamper with it
not to mention, it's really possible. Why is it possible? It's just a relatively mature experiment (with a market value of US $5 billion). In 2007, Satoshi Nakamoto, an anonymous big God or organization, began to conceive a magic project. After more than a year of careful elaboration, Nakamoto completed the white paper of the project (bitcoin: a peer-to-peer electronic cash system, Chinese Name: bitcoin: a peer-to-peer electronic cash system), In early 2009, the project was successfully launched
for the explanation of the principle of the system, I don't want to be a teacher here. For those who are interested, please refer to the information of the college channel or library. It's a very good place for you to understand these things
we just need to know that this e-cash system has nothing to do with paper. It is very transparent. Everyone can access and query this payment account book, and everyone can really control their own bookkeeping rights, that is, bitcoin token. As long as the Internet exists, someone is maintaining this account book (using mining machine operation), Then this kind of payment system can exist forever
well, you say it so well, this kind of system should be very popular, right? Of course not, because it is still in the experimental stage, there are still many defects in this kind of account book. For example, its token value fluctuates greatly, which is not suitable for pricing goods for the time being. For example, it has the problem of scalability. Maybe 100000 people use this system every day, and 10 million people use it to block and collapse. For example, it needs a lot of learning costs, People who don't have relevant knowledge are easy to lose money and so on. In short, there are a lot of problems
can we solve so many problems? Theoretically, it's very possible, because it's open source. Open source means that everyone can review and participate in improvement
of course, it's not to deceive you into buying bitcoin. This is not the purpose of my writing. Talking about bitcoin is just to introce a kind of technology, or an idea. What is it? In other words, blockchain (Chinese name is blockchain) is too popular now. Maybe you don't feel much about it at home. In foreign financial circles, it's no exaggeration to say that this word is the same as Dabao's advertising words
nowadays, foreign companies talk about "blockchain has the potential to subvert xxoo", which is like a common occurrence. Every once in a while, some giant set up a blockchain laboratory, and even the chief economist of the Bank of England raised the possibility of issuing national digital currency based on blockchain
we can't help asking, what is the basis of blockchain? What magic is driving or "deceiving" these institutions to lose their position for such a rising concept
blockchain originated from bitcoin. At present, the most successful blockchain is also bitcoin's blockchain. The reason why blockchain makes people reverie is that it has the characteristics of high transparency, unchangeable and no middleman
suppose I brainstorm and apply these features of blockchain to various applications in other instries, will it proce disruptive effects? Well, it's like now you have a new drug, which can cure all kinds of diseases in theory. Does that mean it's really suitable for treatment? You have to try, because you don't know the side effects! Now the blockchain is in such a stage. It seems to be able to cure all kinds of instries, but in fact it is only in the theoretical stage
when it comes to theory, I have to talk about it
first of all, what is the biggest difference between paper ledger and blockchain ledger
the former accounts by people, while the latter accounts by computer. Because people are too "smart", so bookkeeping is easy to be unexpected, and the efficiency is also very low, but computers are different, computers are "stupid", it is to act according to instructions, and the efficiency will be very high, there is also scalability. Ordinary database is a proct between paper account book and blockchain account book. It can save the system's partial dependence on human beings, but there are also problems in ordinary database. For example, it has access rights, such as the pension you pay. Can you know where they are going
therefore, companies, institutions or indivials with some ideas have gone to study blockchain technology.

3. Because at this stage, all the right issues in China are in an exploratory stage, and the system is not yet complete, so the blockchain can not solve the right problem.
4. It's a way to solve many formality problems. Blockchain is decentralized and transparent. Now many payment channels are studying blockchain technology, maiteng
5. The main reasons for investing in blockchain are as follows:
1. Blockchain is a globally recognized outlet, just like the Internet in the 1990s
2. Blockchain is an advanced technology with great potential
3. With the support of national policies, many governments in the world support blockchain technology
4. Blockchain related applications have emerged, such as digital currency crowdfunding platform, coin Ying China.

6. Blockchain is a permanent and irreversible modified record generated by stacking (chaining) encrypted data (blocks) in chronological order
blockchain is a technology that can completely change the underlying design of the financial system, because it can realize the undifferentiated record between the ownership of all assets in the market and the transaction records of all market participants, so it can completely eliminate the intermediate links of clearing and trusteeship, which are used to confirm the ownership before, ring and after the transaction; In addition, as an electronic information record, blockchain can be combined with computer algorithm to realize the automation of transactions, that is, intelligent contract. There are many derivative applications of blockchain combined with other financial technologies, each of which can replace a kind of market intermediary. Blockchain is to financial services what TCP / IP is to the Internet: once the underlying standards are recognized and popularized, specific applications like bitcoin and R3 will appear in every corner of financial services.

7. Bitcoin is a distributed database. A database can be understood as a block (which contains input, output Amount)
What absenteeism does is to pack the transaction (after the transaction is formed, loitering on the Internet waiting for packing) - pack the block (about 400 transactions in each block) - calculate the answer (hash value) - form a new block (if it meets the requirements, it will be incorporated into the main chain)

8. In the era of blockchain 1.0
this generation of blockchain technology has no application function, which is to issue currency, represented by bitcoin
in the era of blockchain 2.0
blockchain 2.0 is a programmable blockchain
the era of blockchain 3.0
blockchain 3.0 is beyond the financial instry, covering all aspects of social life.

9. With the development of the whole blockchain instry, it is impossible to go back to the past. Bitcoin is far less likely to collapse than it is to reach $100000. Recently, a listed company has undergone earth shaking changes e to the application of a blockchain. Such a magic story will also stimulate more and more giant companies to pay attention to the blockchain, thus promoting the development of the whole instry. The Chicago Mercantile Exchange will launch the bitcoin futures contract in December, which may be another major turning point. It may mark a fundamental change in the game rules and market structure of the whole instry. Although we have missed the legend of bitcoin, from the perspective of the whole blockchain instry, it may be just the beginning to bring blockchain assets into our view of asset allocation.
