Young people's understanding of blockchain

1. 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.

2. Blockchain technology uses mathematical methods to achieve distributed accounting and solve the trust problem, so as to complete the decentralization, which will bring far-reaching influence in many fields such as communication, finance, Internet of things, government management and so on
blockchain refers to the technical solution of collective maintenance of a reliable database through centralization and distrust in the past, and it is a technical way for the whole people to participate in bookkeeping. Previous bookkeeping methods were all centralized and needed centralized intermediary, whether it was traditional government, financial institutions, notarization institutions or emerging e-commerce platform and online payment platform
in economic hypothesis, information is sufficient. In fact, it is precisely because of insufficient information that there are very large intermediaries. The existence of intermediaries increases the transaction cost and raises the transaction threshold. In essence, blockchain technology is a large-scale collaboration tool. It makes direct value transfer possible by using pure technology for the first time, and continues the trend of Internet decentralization and disintermediation. Disintermediated blockchain technology will greatly subvert the information intermediary instry
blockchain technology is the basic technology for building bitcoin data structure and encrypted transmission of transaction information, which realizes the issue and transaction of bitcoin. The core of blockchain technology is that all the current participating nodes jointly maintain the transaction and database, so that the transaction is based on the principle of cryptography rather than trust, so that any agreed parties can directly carry out payment transactions without the participation of a third party
technically, a block is a data structure for recording transactions, reflecting the capital flow of a transaction. In the system, the transaction blocks are connected to form a main chain, and all the nodes participating in the calculation record the main chain or part of the main chain
a block contains the following three parts: transaction information, hash formed by the previous block and random number. Transaction information is the task data carried by the block, including the private keys of both parties, the number of transactions, the digital signature of electronic currency, etc; The hash hash formed by the previous block is used to connect the blocks and realize the sequence of past transactions; Random number is the core of the transaction. All nodes compete to calculate the answer of the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for updating, so as to complete a transaction.

3. Blockchain is a new application mode of distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and other computer technologies. The so-called consensus mechanism is a mathematical algorithm to establish trust and obtain interests between different nodes in the blockchain system
blockchain is an important concept of bitcoin, which is essentially a decentralized database and the underlying technology of bitcoin. Blockchain is a series of data blocks generated by cryptography. Each data block contains the information of a bitcoin network transaction, which is used to verify the validity of the information (anti-counterfeiting) and generate the next block
let's talk about the social or economic significance of blockchain. In fact, many of the previous technologies were devoted to "proctivity". For example, artificial intelligence is a kind of progress in proctivity. The blockchain, which has greatly improved the proction relations, is committed to the proction relations. So why do you say that
because the so-called proction relationship is actually how to do business between people and business partners. And these things, originally, are in the cognitive process between people, and there is no special program to program or quantify it
for example, if you and I are good friends now, we can do business. If someone stirs up our relationship and we are not good friends, we will not do business. Even if we can make money in business, we will not do business because there is no trust between us
as for blockchain, it is actually because the data is authenticated by all nodes and backed up at the same time, so my data is as real as possible and can't be tampered with. In this case, if you believe my data, you can make a program on this basis, and then use the data to make what kind of business contract, what kind of service, what kind of service, and what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, what kind of service, etc This "proction relationship" of commercial cooperation is programmed. In this way, we believe in the data and the program compiled by the algorithm. Because you believe in the data and the program, you can develop all kinds of apps in the program. These apps are the proction relations and what business to do. This is: blockchain is actually a reconstruction of "proction relationship".

4. The definition of Chongqing jinwowo analysis blockchain technology is as follows:
1. Blockchain is a distributed database (system) placed in a non secure environment
2. The blockchain uses cryptography to ensure that the existing data cannot be tampered with
3, the blockchain uses consensus algorithm to reach consensus on new data
the system with the above three properties is blockchain.

5. Buy one or two books about blockchain, and you will have a general understanding of blockchain technology and development prospects. But we should also pay attention to real-time dynamics. China has done a good job in this field. There are weekly, monthly and other instry analysis reports, which are relatively authoritative in China.

6. In essence, blockchain represents a transformation from monopoly of technical authority to decentralization, that is, a distributed concept“ Blockchain has three characteristics: tamper proof, whole process recording and encryption system, which can make the right of data more democratic, "said the above-mentioned person in charge of jinwowo group. By solving the problem of data ownership right, jinwowo blockchain has built a large number of blockchain digital asset networks with rich asset types, Its overall architecture has covered the entire southwest region“ With the increasing maturity of blockchain technology, jinwowo will be distributed throughout the country, dedicated to the Internet technology service platform of comprehensive collection, efficient storage, in-depth analysis of big data for the majority of small and medium-sized enterprises, and ultimately promoting the legal sharing and value circulation of big data

7. Let me tell you this. Those who say no pumping are hooligans! There's no pie in the sky. Development of a mining software needs a lot of time, energy, financial and material resources, and then said free to you, and do not have any benefits, do you believe it? A lot of software with the slogan of free pumping, in fact, pumping than no one is low! For example, Changsha miners! Some tests do not require pumping, but the power of stealing calculation is higher than that of pumping! So, it is said that the mining software without pumping, give up decisively!

8. The simple one is that e-money is not the traditional cash, but the transaction of data and data. No matter how you transfer or how you trade, the cash is in the bank, and the bank's money is invested, which is very helpful to the economic development and the dominant direction of money in the future. However, there are also shortcomings. E-money is very easy for the financial sector to cause economic bubbles. The same financial effect is doubling the financial effect. That is to say, funds have a circulation function in numbers, but in terms of banks, the cash they are holding has an additional effect on the circulation of electronic money in the society. It will inevitably rece the circulation of cash and RMB in the market, which will easily lead to inflation and price rise.

9.

At present, with the rapid development of science and technology, the situation is surging. If you and I are a little lazy, we may be out. No, the new blockchain is coming. Since the beginning of this year, blockchain has become one of the hottest knowledge points in the field of science and technology, and has become increasingly prominent in the fields of digital finance, Internet Governance and big data computing

blockchain technology also has broad application prospects in the military field, which is very likely to quietly subvert the future war

this is not Xiaole's boasting“ There is nothing more important about the three armed forces than secrecy. " We should know that in the future information battlefield, confidentiality is the key to win or lose the war. Because the blockchain system has many characteristics such as information independence, confidentiality and integrity, it can realize the perfect combination of data storage and data encryption. After being attacked, it also has strong recovery ability, and can protect highly sensitive data, which is of great help to win the war

according to the information collected by Xiaole, some countries are planning to build blockchain information platform and begin to study the application potential of blockchain in several scenarios such as military satellites and nuclear weapons; An international organization is currently evaluating the performance of blockchain technology in military logistics, Internet of things and other fields

if bitcoin and other digital currencies are blockchain 1.0 applications, blockchain 2.0 is the "smart contract" that provides a strong guarantee for network transaction data security. There will be 3.0 in the future, from Dao (blockchain self consistent organization), DAC (blockchain self consistent company) to blockchain society

"cultivate new kinetic energy with informatization, promote new development with new kinetic energy, and create new brilliance with new development." I believe that blockchain, the "new kinetic energy" of science and technology, will bring us more surprises: "one machine in hand, I have it in the world", "trade autonomy", more extensive sharing, and the optimal life mode... Blockchain technology will create a more honest, convenient, and efficient Era of big data
