Blockchain subversion

1. The subversive characteristics of blockchain lie in the following four aspects: first, transparency. The data record of the blockchain system is transparent to the nodes of the whole network, and the update operation of the data record is also transparent to the nodes of the whole network, which is the basis of the trustworthiness of the blockchain system. Because the blockchain system uses open source programs, open rules and high participation, the data records and operation rules of the blockchain can be reviewed and traced by the nodes of the whole network, with high transparency< Second, openness. The blockchain system is open. In addition to the fact that the private information of the parties directly related to the data is always encrypted, the data of the blockchain is open to all (except the blockchain system with special permission requirements). Anyone or participating nodes can query blockchain data records or develop related applications through the open interface, so the information of the whole system is highly transparent< Third, information can not be tampered with. Once the information of the blockchain system is verified and added to the blockchain, it will be permanently stored and cannot be changed (except for private blockchain systems with special change requirements). Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high
Fourth, decentralization. Decentralization is the most basic feature of the blockchain, which means that the blockchain no longer depends on the central processing node and realizes the distributed recording, storage and updating of data. In the traditional centralized network, attacking a central node can destroy the whole system, while in a decentralized blockchain network, attacking a single node cannot control or destroy the whole network. More than 5% of the nodes in the master network are just the beginning of gaining control. 2019 is the first year for the commercial application of blockchain technology, and the stimulation of favorable policies will make the development of blockchain technology more stable
with the application of blockchain technology graally penetrating into many fields such as digital finance and Internet, we have a clearer understanding of the value of blockchain
blockchain has formed a situation of global competition, and all countries are seizing the development opportunities, let alone China; Therefore, there is no doubt that blockchain has become a national strategy.

2. Femtosecond detection found that 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. Its characteristics include:
decentralized
e to the use of Distributed Accounting and storage, there is no centralized hardware or management organization, the rights and obligations of any node are equal, and the data blocks in the system are jointly maintained by the nodes with maintenance function in the whole system
thanks to the decentralization of blockchain, bitcoin also has the characteristics of decentralization [6]

openness
the system is open, in addition to the private information of all parties to the transaction is encrypted, the data of the blockchain is open to all, and anyone can query the blockchain data and develop related applications through the open interface, so the information of the whole system is highly transparent
autonomy
blockchain adopts consensus based specifications and Protocols (such as a set of open and transparent algorithms) to enable all nodes in the whole system to exchange data freely and safely in a de trusted environment, so that the trust in "people" is changed into the trust in machines, and any human intervention does not work
information cannot be tampered with
once the information is verified and added to the blockchain, it will be stored permanently. Unless more than 51% of the nodes in the system can be controlled at the same time, the modification of the database on a single node is invalid, so the data stability and reliability of the blockchain are extremely high<
anonymity
since the exchange between nodes follows a fixed algorithm, their data interaction does not need to be trusted (the program rules in the blockchain will judge whether the activity is effective by themselves), so the counterparties do not need to trust themselves by disclosing their identities, which is very helpful for credit accumulation

3. At present, the blockchain instry and technological innovation are developing rapidly, which has extended to many fields, such as digital finance, Internet of things, intelligent manufacturing, supply chain management, digital asset trading, and even disruptive innovative applications. But these may just be the beginning. Blockchain will continue to restructure subversive applications in the field of commercial economy, social life governance, and even proction relations. Blockchain + instry innovation is an inevitable thing in the current situation. The blockchain + public service mode initiated by Changsha high tech Zone, which now has a SMIC blockchain service platform project, is soliciting enterprises to join the chain. In the future, relevant enterprise affairs and government affairs can cooperate on the chain.

4.

A few days ago, some media reported that the Internet can be called a great revolution. Since its birth, it has constantly refreshed its imagination and transformed the world, and the blockchain is subversive

in the early stage of blockchain development, on the one hand, it needs the full brewing of the market, on the other hand, it needs the guidance of the government. Blockchain may bring some challenges to the current laws and regulations, especially in the financial field. We do not have to predict its future, but to do a good job in process supervision, the next step is to see the application and development of blockchain in all aspects

5. The subversion from blockchain is a manifestation of digital currency becoming a national line. Now the country should actively promote the development of blockchain.

6. First,
decentralized feature
as the name suggests, a blockchain does not need a centralized server, and all the information is stored on each node in the chain in a distributed form. Even if a node is damaged or tampered, the operation of the whole blockchain will not be affected, and the data will not be disordered
Second, consensus mechanism
consensus mechanism plays an important role in the trustworthiness of data on blockchain. Due to the decentralized architecture, any two nodes in the chain do not need to trust each other's identity to establish a connection, and there is no need to trust each other for data exchange. Since all nodes in the network can act as "supervisors", there is no need to worry about fraud. When a transaction is completed, all nodes on the blockchain will synchronize this information, so the consensus mechanism is based on the distributed architecture to ensure the data can not be tampered with
Third, smart contract
before we talk about blockchain + smart contract, let's first clarify the meaning of smart contract: a set of commitments defined in digital form, on which contract participants can implement these commitments. Generally speaking, it is a smart contract. In a computer system, when certain conditions are met, the contract can be executed automatically.

7. The emergence of blockchain is an iteration of economic and social evolution to a certain extent. It can improve economic growth and break the original investment threshold. The characteristics of blockchain make investors happy. However, e to the progress of national strategy, blockchain has developed rapidly and has been valued by the state. It's good to have a hashton blockchain company.

8. It will be many years before the instry and government reform really guided by blockchain can be realized. The reason is that blockchain is not a "subversive" technology. It can not subvert the traditional business model with a lower cost solution and quickly overwhelm the incumbent enterprises. Blockchain is a "fundamental" technology: it has the potential to create a new foundation for the economic and social system. Although its impact is enormous, it will take decades to penetrate into our economic and social infrastructure. With the rapid development of technology and system reform, the application of blockchain will be steadily promoted
blockchain is a P2P network based on the Internet, which was first used in bitcoin protocol in October 2008. Bitcoin is a virtual currency system; It decentralizes currency issuance, ownership transfer and transaction confirmation. Bitcoin is the first application case of blockchain technology. Digital currencies such as Puyin, Laite coin and doggy coin are also the application of blockchain.

9. Some people predict that blockchain may cause unemployment in banking, auditing and other instries

blockchain is like an account book. Every point in the Internet is being accounted for so that reconciliation can be made. For example, there are people blowing plastic bottles in sweatshops in the south. The workers and the boss keep a record. At the end of the month, the workers made 8000 bottles, but the boss had only 5000. Then one by one. Two people's accounts, of course, need to be signed. But if there are three or more people checking accounts, there is almost no mistake. You can know what it is by studying a pair of details

in this case, it will not be so troublesome to send money to the bank. The Internet is already convenient, from one point on the earth to another, that is, a matter of seconds. How much money has been remitted? There may be countless points in the bookkeeping. In general, as long as there are six points to ensure, the blockchain will regard it as correct. In addition, we can boldly guess that the audit work is unnecessary

blockchain is the underlying technology of bitcoin. Now bitcoin is slowly cooling down, but its methods remain. Now there are applications in voting places. Just like e-commerce, people used to think that they were cheaters, but now they are developing very well.

10. According to this development trend, I think it will. Because of the characteristics of disintermediation, openness, non tampering, programmability and so on, the blockchain itself is easy to be valued and developed. Just like blockgame, the new model of blockchain + game is highly praised
